Recover & Feel More Comfortable

Support Recovery Through Nutrition

After exercise, your body is mending muscle, refilling its energy stores and replacing the fluid you sweated out, and food and drink are the raw materials for all of that. This page is about what to eat and drink to support recovery, and which recovery supplements have evidence behind them; sore muscles, rest days, training load and overall recovery have their own pages.

General information, not medical advice. Last updated October 31, 2026. Written by the AlternativeMed editorial team. Not medically reviewed.

Start here

Eat enough overall and keep regular meals: recovery runs on total food, and eating too little for the amount of activity you do can harm both health and performance.
Include a protein food (for example dairy, eggs, fish, meat, beans or lentils, soya) in each meal and snack across the day, and have a meal or snack that combines carbohydrate and protein within a couple of hours of hard or long sessions, especially if you will train again soon.
Drink to replace what you sweated out, and check that your pee is a clear pale yellow; after long or sweaty sessions, drinks or food that contain some salt help your body keep the fluid.

Be careful with

Do not try to speed recovery by eating less. Low energy intake relative to exercise is linked with harm to health and performance in both women and men, and restricting, bingeing, purging or fear of eating need professional support, not a recovery plan.
Supplements are an optional extra, not the base of recovery. "Natural" does not mean risk-free: check with a pharmacist or doctor first if you take any medicine, are pregnant or breastfeeding, are under 18, or have kidney disease, diabetes or another long-term condition.
Do not change or stop a prescribed medicine, and do not change a diet set by your care team (for example for diabetes or kidney disease), because of a recovery plan you read online.

Get help when

Tiredness, poor performance or low mood that last for weeks despite rest and enough food, or exercise that leaves you wiped out for days (see the fatigue and ME/CFS pages).
Dark urine together with severe muscle pain or weakness after exercise, or signs of serious dehydration such as dizziness that does not go away, confusion, fast breathing or very little urine. The NHS lists these as reasons to get urgent help and names 111 for urgent advice and 999 for emergencies in the UK; elsewhere use your local emergency number.
Unplanned weight loss, missed periods, repeated stress injuries, or a worrying relationship with food or exercise. A doctor or registered dietitian can help, and so can an eating-disorder service.
Vomiting or diarrhoea that stops you keeping fluids down, especially in children, older adults and pregnancy.

About Support Recovery Through Nutrition

What this goal means

This goal is about using food and drink to support the body after exercise: refilling energy stores (glycogen), supplying protein for muscle repair and adaptation, and replacing fluid and salts lost in sweat. A joint position statement from the American College of Sports Medicine and two dietetics bodies says that performance and recovery from sport are enhanced by well-chosen nutrition, and that athletes should be referred to a registered dietitian for a personal plan.

It is not about a single magic food or a recovery shake. It is about the everyday pattern of eating that makes the other recovery steps work.

What it can feel like

People often notice they feel flat, hungry or heavy-legged for a day after hard sessions, struggle to train well on consecutive days, feel light-headed or headachy after sweating, or are unsure what to eat when they are not hungry straight after exercise.

What affects how well food supports recovery

The main factors are total energy eaten compared with energy used, daily protein, carbohydrate in relation to how long and hard you train, how much you sweated and what you drank, and how soon you need to train again. Recovery after an easy walk needs no special plan; recovery between two hard sessions in the same day is where timing matters most.

The International Society of Sports Nutrition (ISSN) nutrient timing position stand focuses on healthy exercising adults, and particularly highly trained people, and says that meeting total daily protein intake, with protein spread across the day, should be a primary area of emphasis.

Conditions and situations to be aware of

Low energy availability (too little food for the amount of exercise) can cause a pattern of problems the International Olympic Committee calls Relative Energy Deficiency in Sport, which affects health and performance in female and male athletes. Disordered eating can sit behind it.

Kidney disease is common, often has no symptoms in the early stages, and changes what is safe to eat and take. Diabetes, pregnancy, breastfeeding and older age also change nutrition needs, so these groups should plan with a clinician or registered dietitian.

^3,4

Realistic expectations

Good nutrition supports recovery; it does not remove the need for sleep, rest days and sensible training loads. The research on recovery foods and supplements is mostly small, short and done in young, trained men, so effects reported in studies may be smaller or different in other people.

Most people who exercise for health, rather than as an athlete, do not need special recovery products. A balanced diet, enough protein and enough fluid cover most of what the research supports.

^5,6

Who this applies to

Anyone who exercises regularly and wants to eat and drink in a way that helps them recover, from beginners to club athletes. Recovery after illness, after an injury or from overall tiredness is covered on separate pages, and a persistent drop in energy or performance needs a medical check rather than a new diet.

A manageable starting plan

An educational starting point, not a personal prescription. Adjust it to your own situation and any advice from your clinician.

Your first actions

Eat regular meals with enough food for your training, with a protein food at each meal.
Drink steadily through the day and after sessions; check that your pee is pale yellow.
After hard or long sessions, especially when you train again within a few hours, have a snack or meal with carbohydrate and protein soon after.
Look at sleep and rest days before adding any product.

Optional additions

Try a glass of milk or a yogurt or kefir as a post-session snack.
If you get very sore after hard sessions, you could trial tart cherry for a few weeks and see whether it helps you.
Weigh yourself before and after a long, sweaty session to see how much fluid you lose.

What to track

Energy, hunger, sleep and mood through the week.
Pee colour, headaches and dizziness after training.
Soreness and how long it takes before you feel ready to train again.
Any supplement you try, its start date and any side effects.

When to reassess

Give food and drink changes two to four weeks. If you are still very tired, sore for several days after easy sessions, losing weight without meaning to, or your performance is dropping, see a doctor or registered dietitian instead of adding more products.

When to seek professional support

Speak to a doctor if tiredness, low mood or reduced performance lasts for weeks.
See a registered dietitian for a personalised plan, especially with diabetes, kidney disease, pregnancy, a vegetarian or vegan diet or a history of disordered eating.
Get urgent help for dark urine with severe muscle pain, ongoing dizziness, confusion or very little urine.

What helps

Ordered by how well the research supports each step. Evidence strength is shown on every card; precautions sit next to the advice.

Start here

Eat enough, with regular meals

Moderate certainty

Addresses: Gives the body the energy it needs to repair and adapt

Why it may help: The IOC consensus statement describes health and performance harm in women and men who take in too little energy for the exercise they do. The NHS Eatwell Guide describes a balanced day built from fruit and vegetables, starchy foods, protein foods, dairy or alternatives, and small amounts of unsaturated fats.

How to apply it: Base meals on starchy foods and vegetables with a protein food, eat at regular times, and add a snack on heavier training days instead of cutting back.

Who it may suit: Anyone who exercises regularly, particularly people who have noticed low energy, poor sleep or frequent illness during hard training.

Precautions: If you feel afraid to eat, or exercise to "earn" food, talk to a clinician or an eating-disorder service. Needs differ in pregnancy, breastfeeding, adolescence, older age and with long-term conditions.

^3,6

Eating disorders and disordered eating →

Spread protein across the day

Moderate certainty

Addresses: Supports muscle repair and the gains from strength training

Why it may help: The ISSN position stand says a daily protein intake of about 1.4 to 2.0 g per kg of body weight is enough for most exercising people, and suggests dividing protein into servings of roughly 20 to 40 g about every 3 to 4 hours. It also says the benefit of timing around the workout is mostly a matter of what you tolerate. A meta-analysis of 49 trials found protein supplements gave a small extra gain in muscle size and strength during resistance training, with no further gain beyond about 1.6 g/kg/day total protein, and a smaller effect with increasing age.

How to apply it: Include a protein food at each meal and snack, such as dairy, eggs, fish, poultry, tofu, beans or lentils. Whole foods that contain all the essential amino acids are the position stand's first suggestion.

Who it may suit: Most adults who exercise, especially those lifting weights or training hard.

Precautions: People with kidney disease or reduced kidney function should ask their kidney team how much protein suits them before raising intake. Older adults, people who are pregnant and people on special diets should seek individual advice.

^7,8,4

Strength training and protein for older adults → Build Muscle Mass →

Have a carbohydrate-and-protein meal after hard or long sessions, particularly when you train again soon

Moderate certainty

Addresses: Refills muscle energy stores (glycogen) and starts repair

Why it may help: The ISSN nutrient timing position stand says that when there are fewer than 4 hours between hard sessions, eating carbohydrate soon after exercise, and combining it with protein, helps restore glycogen faster, and that protein eaten from straight after to about 2 hours after exercise stimulates muscle protein synthesis.

How to apply it: A meal or snack of rice, pasta, potatoes, bread, oats or fruit with a protein food such as yogurt, eggs, milk, fish, beans or lentils.

Who it may suit: People training more than once a day, endurance athletes and anyone doing long or very hard sessions. If you train once a day with a day between sessions, regular meals and enough protein across the day are the main thing.

Precautions: People with diabetes should plan carbohydrate with their care team. This is a position statement, not a set of large clinical trials.

^2,1

Prediabetes, type 2 diabetes and metabolic syndrome →

Replace fluid after exercise, with some salt in the mix

Moderate certainty

Addresses: Restores fluid balance and helps you start the next session well hydrated

Why it may help: The American College of Sports Medicine position stand says that after exercise the goal is to replace the fluid and electrolyte deficit, and suggests weighing yourself before and after exercise to estimate your sweat loss. A review of post-exercise rehydration says the volume drunk should be more than was lost, that large amounts of plain water are quickly passed as urine, and that adding sodium and food helps the body keep the fluid. The NHS says water is the best way to replace lost fluids and to drink extra when sweating from physical activity.

How to apply it: Sip steadily after exercise instead of drinking a lot at once, have a meal or snack with some salt, and aim for a clear pale yellow pee.

Who it may suit: Anyone who sweats in exercise, particularly in hot weather or in long or repeated sessions.

Precautions: Drinking very large amounts of plain water is not better. If you have a heart, kidney or hormone condition, or take water tablets, ask about the right fluid amount for you. Children, older adults and people with diarrhoea or vomiting dehydrate more easily.

^9,10,11

Stay Hydrated for Daily Wellbeing →

Build meals around whole foods first

Moderate certainty

Addresses: Covers recovery needs without relying on products

Why it may help: The ISSN protein position stand says it is possible for active people to meet protein needs from whole foods and suggests focusing on whole food protein sources, and the NHS says most people get the nutrients they need from a varied, balanced diet.

How to apply it: Think of a plate with a protein food, a starchy food, vegetables or fruit, and a drink. Add a snack if training is heavy.

Who it may suit: Almost everyone.

Precautions: Allergies, intolerances, vegetarian or vegan eating and medical diets need planning so protein, iron, vitamin B12 and energy are covered.

^7,5

Anemia and iron deficiency → Vitamin B12 deficiency →

Additional options

Milk or chocolate milk after exercise

Low certainty

Addresses: A simple drink that combines fluid, carbohydrate and protein

Why it may help: In a trial of 72 men, full-fat and skimmed milk kept more fluid in the body over the next hours than plain water. A systematic review of 12 trials in trained athletes found chocolate milk worked as well as, or better than, water or other recovery drinks on some measures, such as time to exhaustion in later exercise, but not on most others, and said the evidence is limited.

How to apply it: A glass of milk, or a yogurt or kefir drink, with a snack. Choose plant-based alternatives that are fortified if you do not drink dairy.

Who it may suit: People who tolerate milk and want a convenient option.

Precautions: Not suitable for milk allergy; lactose intolerance may cause gut symptoms. Chocolate milk contains added sugar, so it is not an everyday drink for everyone.

^12,13

Cows milk → Kefir →

Carbohydrate-and-electrolyte drinks in specific situations

Moderate certainty

Addresses: Replaces fluid, salts and energy when sessions are long or hot or when time is short

Why it may help: The American College of Sports Medicine position stand says drinks that contain electrolytes and carbohydrate can have benefits over water alone under certain circumstances. The NHS gives water as the first choice and advises cutting down on sugary drinks.

How to apply it: Consider them for very long or repeated sessions, heavy sweating or when you cannot eat soon after exercise. For most short workouts, water and a normal meal are enough.

Who it may suit: Endurance athletes and people training in the heat.

Precautions: They contain sugar or sweeteners and sometimes caffeine. If you have diabetes or high blood pressure, or are limiting salt for medical reasons, ask your care team first.

^9,11

Sports and electrolyte drinks → Coconut water →

Casein protein (for example milk protein or yogurt) before sleep

Low certainty

Addresses: May add to overnight muscle protein synthesis

Why it may help: The ISSN position stand says that eating about 30 to 40 g of casein before sleep increases overnight muscle protein synthesis. This is a measure of muscle building, not proven faster recovery.

How to apply it: A bowl of yogurt or a glass of milk as an evening snack on heavy training days, if it suits you.

Who it may suit: Strength trainees and people with higher protein needs who like an evening snack.

Precautions: A late, large meal can interfere with sleep or reflux in some people. Not suitable for milk allergy.

^7,2

Yogurt →

Still being studied

Tart cherry (juice or concentrate)

Low certainty

Addresses: May ease muscle soreness and speed strength recovery after hard exercise

Why it may help: A meta-analysis of 14 studies found tart cherry had a small effect on muscle soreness and moderate effects on recovery of strength and power. A 2026 network meta-analysis of 30 trials (595 people) found pomegranate and tart cherry were the only plant supplements to reduce soreness at 48 hours, but none clearly improved strength or blood markers, and the certainty of evidence was generally low.

How to apply it: Studies used tart cherry juice or concentrate around heavy sessions. We did not find a dose that is set by an agency, so none is given here.

Who it may suit: Trained adults with sore muscles after very hard sessions who want to try a food-based option.

Precautions: Cherry juice contains sugar; the effect is about soreness, not about faster healing. People with diabetes should check with their care team.

^14,15

Tart cherries and cherry juice → Pomegranate →

Creatine for recovery

Low certainty

Addresses: May help recovery between hard sessions

Why it may help: The ISSN position stand reports that creatine supplementation may enhance post-exercise recovery and help athletes tolerate heavy training, and says that short- and long-term use was safe and well tolerated in healthy people in the studies it reviewed. Its strongest evidence is for high-intensity performance, not recovery.

How to apply it: Studies used creatine monohydrate as a powder. Dose is not given here; see the creatine page.

Who it may suit: Healthy adults doing high-intensity or strength training.

Precautions: Ask a clinician first if you have kidney disease or take medicines that affect the kidneys, or if you are pregnant, breastfeeding or under 18. In tested sport, check your sport's rules.

^16,4

Creatine →

Branched-chain amino acids (BCAA)

Low certainty

Addresses: May lessen soreness a day or two after hard exercise

Why it may help: A meta-analysis of ten trials found BCAA reduced soreness 24 to 72 hours after exercise in trained people with mild to moderate muscle damage, but results varied and the authors could not say it works for untrained people. A broader umbrella review of nutrition studies rated BCAA effects on soreness as moderate certainty.

How to apply it: Whole protein foods already supply BCAA; the studies used isolated BCAA supplements.

Who it may suit: Trained adults who are sore after hard sessions and whose protein intake is already adequate.

Precautions: If you already eat enough protein, extra BCAA is unlikely to add much. Ask a clinician first if you have a liver, kidney or metabolic condition.

^17,18

BCAAs: leucine, isoleucine and valine →

Curcumin (from turmeric)

Mixed findings

Addresses: May reduce muscle soreness after hard exercise

Why it may help: One meta-analysis of ten trials reported lower muscle soreness and muscle-damage blood markers with curcumin supplements, while a later review of 16 papers found no statistically significant effect on muscle damage, soreness or inflammation. The two reviews disagree and both call for better trials.

How to apply it: Studies used curcumin supplements, not turmeric cooking spice. We did not find a reliable dose for this goal.

Who it may suit: Not clear. It is a food-first spice with an uncertain supplement benefit.

Precautions: Curcumin supplements may interact with some medicines; check with a pharmacist or doctor, and ask first in pregnancy or breastfeeding.

^19,20

Turmeric →

Omega-3 fats (fish oil)

Mixed findings

Addresses: May reduce soreness and support muscle function after hard exercise

Why it may help: The evidence conflicts. A 2020 meta-analysis of 12 trials found a small reduction in soreness that was below the level counted as a meaningful difference, and a 2026 review of 43 studies called results equivocal but found benefits in a pooled analysis of nine placebo-controlled trials of eccentric exercise, noting serious design limits.

How to apply it: The NHS Eatwell Guide suggests at least two portions of fish a week, one of them oily; the studies above used supplements.

Who it may suit: Not clear. Fish as food is a reasonable base.

Precautions: Fish oil supplements may interact with some medicines; check with a pharmacist or doctor before using them, and ask first in pregnancy or breastfeeding.

^21,22,6

Fish oil → ALA, EPA and DHA →

Food & nutrition

Enough energy across the day

Recovery starts with enough food overall. The NHS Eatwell Guide shows a day made from just over a third fruit and vegetables, just over a third starchy foods, then protein foods, dairy or alternatives and small amounts of unsaturated oils, and says you do not need to get the balance right at every meal but over a day or a week. Active people usually need more than the guide average, and the American College of Sports Medicine joint statement recommends a registered dietitian for personal plans.

Signs that you may be eating too little for your activity can include constant tiredness, falling performance, frequent illness or injuries, and low mood. The IOC consensus describes harms to health and performance from low energy availability and provides a clinical tool for doctors to assess it.

Base meals on starchy foods such as rice, potatoes, oats, bread or pasta, choosing wholegrain where you can.
Add an extra snack on heavy training days instead of cutting meals.

^6,1,3

Protein foods

The ISSN position stand says a daily protein total of about 1.4 to 2.0 g per kg is sufficient for most exercising people and that servings of about 20 to 40 g spread every 3 to 4 hours are most effective. In practical terms that is a palm-sized portion of a protein food at each meal. The Eatwell Guide lists beans, pulses, fish, eggs, meat, dairy and soya as protein foods, and suggests two portions of fish a week, one of them oily.

Plant protein can be used too. The ISSN notes that it is the essential amino acids that stimulate muscle protein synthesis, and that rapidly digested proteins with enough leucine are most effective, so it helps to include a variety of protein foods.

Eggs, yogurt, milk, cheese or kefir.
Fish and poultry; lean meat in moderation, with less red and processed meat as the NHS advises.
Beans, lentils, tofu and other soya foods, nuts and seeds.
Protein powder, only if you need it to reach your total.

^7,6

Carbohydrate for refuelling

Carbohydrate refills the glycogen your muscles burn through. The ISSN says glycogen stores are depleted most by high-volume exercise, and that when you need to restore glycogen quickly (less than 4 hours before the next hard session), eating carbohydrate soon after exercise, and adding protein, is the approach to consider..

Rice, pasta, potatoes, bread, oats or porridge, bananas and other fruit.
Pair them with a protein food in the same meal or snack.

Fluids and salt

The NHS suggests 6 to 8 cups or glasses of fluid a day as a guide, more if you are active for long periods, and a pale yellow pee as the target. The American College of Sports Medicine says sweat rates differ a lot between people and suggests estimating your own by weighing yourself before and after exercise, then replacing the deficit. In a trial of 72 men, milk and an oral rehydration solution kept more fluid in the body than water over four hours.

Food counts too. Soups, fruit, yogurt and salad provide fluid, and the salt in a meal helps the body hold on to what you drink.

Water is the base. Milk and unsweetened tea or coffee also count.
After long or very sweaty sessions, include a salty food or a drink with electrolytes.
Limit fruit juice and smoothies to a combined 150 ml a day with meals, as the NHS advises.

^11,9,12

Fruit, vegetables, nuts and healthy fats

Fruit and vegetables supply vitamins, minerals and fibre. Studies of tart cherry and pomegranate suggest plant polyphenols may help with soreness, but the effects are small and the certainty low. Oily fish and nuts provide unsaturated fats that the Eatwell Guide includes in a balanced diet.

Berries, cherries, pomegranate, citrus fruit and leafy greens.
Oily fish such as salmon, sardines or mackerel; walnuts and other nuts.
Unsaturated oils such as olive or rapeseed oil in small amounts.

^6,15

Remedies & supplements

Traditional use, laboratory findings and human trials are kept apart. "Natural" does not mean safe.

Creatine

Low certainty

Studied form and route: Creatine monohydrate powder taken by mouth

Intended outcome: Support for high-intensity training and, possibly, recovery between sessions

Human evidence: The ISSN position stand reports that creatine supplementation may enhance post-exercise recovery and help athletes tolerate heavy training loads, and found short- and long-term use safe and well tolerated in healthy people in the studies it reviewed.

Limits: The strongest evidence is for strength and high-intensity performance. The recovery claims in the stand are less well established.

Interactions and precautions: Ask a clinician before use if you have kidney disease or take medicines that affect the kidneys. Ask a clinician first if you are pregnant, breastfeeding or under 18. Check anti-doping and sport rules if you compete.

^16,4

Creatine →

Protein powders (whey and plant proteins)

Moderate certainty

Studied form and route: Powders or ready-to-drink shakes

Intended outcome: A convenient way to reach a daily protein total and support muscle gains with strength training

Human evidence: A meta-analysis of 49 trials in 1,863 people found protein supplements modestly increased strength and lean mass during resistance training. The ISSN says whole foods are a good first choice and supplements are a practical way to reach protein targets.

Limits: The gain is small on average, falls with older age, and stops when total protein is already high. Most trials were of strength training, not recovery between sessions.

Interactions and precautions: Not suitable for milk or soy allergy where those are the source. People with kidney disease should ask their kidney team first. Check labels, and anti-doping rules for tested sport.

^8,7,4

Protein powder → Plant protein powders →

Tart cherry

Low certainty

Studied form and route: Tart cherry juice, concentrate or capsules

Intended outcome: Less muscle soreness and quicker return of strength after very hard exercise

Human evidence: A meta-analysis of 14 studies found small to moderate benefits for soreness, strength and power, and a 2026 network meta-analysis of 30 trials found it was the most consistent plant supplement for easing soreness, though certainty was low.

Limits: Mostly small trials in young adults using different products and schedules.

Interactions and precautions: Contains natural sugars in juice form; people with diabetes should check with their care team.

^14,15

Tart cherries and cherry juice →

Curcumin

Mixed findings

Studied form and route: Curcumin supplements, often combined with an absorption aid

Intended outcome: Less muscle soreness

Human evidence: One meta-analysis of ten trials found lower soreness and muscle-damage markers. A later review found no statistically significant effects.

Limits: The reviews disagree, trials are small and use varied products.

Interactions and precautions: May interact with some medicines; ask a pharmacist, and ask first in pregnancy or breastfeeding.

^19,20

Turmeric →

Omega-3 fish oil

Mixed findings

Studied form and route: Fish oil or algae oil capsules

Intended outcome: Less soreness and better muscle function after hard exercise

Human evidence: Reviews conflict: a 2020 meta-analysis found a soreness reduction too small to matter in practice, and a 2026 review found benefits in a subset of nine eccentric-exercise trials but called the whole literature equivocal.

Limits: Methods, products and timing varied between trials, so reliable dosing could not be set.

Interactions and precautions: May interact with some medicines. Check with your pharmacist or doctor if you take any, and ask first in pregnancy or breastfeeding.

^21,22

Fish oil →

BCAA supplements

Low certainty

Studied form and route: Branched-chain amino acid powders or capsules

Intended outcome: Less soreness 24 to 72 hours after hard exercise

Human evidence: A meta-analysis of ten trials found reduced soreness in trained people after mild to moderate muscle damage; an umbrella review rated the soreness effect as moderate certainty.

Limits: Mixed results, differing doses and timing, and no clear benefit shown in untrained people. Whole protein already contains BCAA.

Interactions and precautions: Ask a clinician if you have a liver, kidney or metabolic condition.

^17,18

BCAAs: leucine, isoleucine and valine →

High-dose vitamin C and E supplements

Evidence against

Studied form and route: Antioxidant vitamin tablets

Intended outcome: Marketed to reduce inflammation and speed recovery

Human evidence: We did not find a trial showing recovery benefits. One controlled trial of 39 men found these vitamins blocked some of the adaptations to training over 4 weeks.

Limits: Small, short trial of metabolic outcomes in young men; not a direct test of recovery.

Interactions and precautions: Check amounts with a pharmacist. The NHS says most people get what they need from a balanced diet.

^23,5

Vitamin C →

Therapies & care

Established professional help for nutrition and recovery starts with a registered dietitian or doctor. Check for causes such as low iron or low energy intake if you are persistently tired or your performance falls, and get help promptly if food or exercise feels out of control. Never stop or change a prescribed medicine or medical diet because of a recovery plan.

Registered dietitian or sports dietitian

Moderate certainty

Professional nutrition advice A personalised plan for energy, protein, carbohydrate, fluids and any supplements around your training and health.

Who it may suit: Athletes, people training hard or often, vegetarians and vegans, people with food allergies, diabetes or kidney disease, and anyone who is unsure how much to eat.

Precautions: Look for a registered professional. In some countries the title is protected.

Medical check for unexplained tiredness or falling performance

Moderate certainty

Primary care assessment A doctor can look for causes such as anaemia, low vitamin levels, low energy intake, illness or overtraining.

Who it may suit: Anyone whose tiredness or performance has dropped for weeks despite rest and enough food.

Precautions: Do not self-treat with iron or other supplements before testing.

^3,5

Fatigue: when to get help → Anemia and iron deficiency →

Eating-disorder support

Moderate certainty

Specialist care Specialist services support people who restrict, binge, purge, over-exercise or fear eating. Recovery nutrition is not the answer to these problems.

Who it may suit: Anyone worried about their relationship with food or exercise, or someone concerned about another person.

Precautions: Start with a doctor or a national eating-disorder service.

Eating disorders and disordered eating →

What to avoid

Habits, products and claims that can get in the way. Never stop a prescribed medicine without talking to the professional who prescribed it.

Risks that apply to most people

Under-eating to "stay lean" while training hard

Moderate certainty

Why: The IOC consensus links low energy availability (too little energy for the amount of exercise) with health and performance problems in women and men, and also reports a growing link with mental health.

Who it applies to: People who train hard and diet at the same time, people with a history of disordered eating, adolescents and endurance or weight-class athletes.

Try instead: Match food to training, add snacks on hard days, and speak to a doctor or registered dietitian if weight, periods, mood or performance are changing.

Eating disorders and disordered eating →

Relying on large amounts of plain water alone to rehydrate

Moderate certainty

Why: A review of post-exercise rehydration says large volumes of plain water bring on a quick increase in urine and so do not keep fluid in the body for long, whereas sodium and food help.

Who it applies to: Heavy sweaters and anyone drinking a lot at once after exercise.

Try instead: Drink steadily, with food, and include some salt in what you eat or drink.

¹⁰

Personal triggers to check

Alcohol straight after exercise

Moderate certainty

Why: The review of post-exercise rehydration notes that alcohol is often drunk after exercise and may affect rehydration. The NHS lists drinking too much alcohol among causes of dehydration and advises avoiding it when dehydrated.

Who it applies to: People rehydrating after long or hot sessions and anyone who sweats heavily.

Try instead: Rehydrate and eat first; if you drink alcohol, keep it moderate and have it with food and water.

^10,24

A very large meal or lots of fluid just before or straight after hard effort when your stomach is unsettled

Not enough evidence

Why: We did not find a study that tests this. The ISSN protein position stand says the best time to eat protein around a workout is likely a matter of individual tolerance, so there is no need to force food down if it upsets you.

Who it applies to: People who get stomach upset, nausea or reflux when they eat soon after exercise.

Try instead: Try small portions or drinks, like yogurt, a banana or milk, and build up as you tolerate them.

⁷

Manage Nausea & Stomach Discomfort →

High-protein diets, protein powders or creatine if you have kidney disease

Not enough evidence

Why: The NHS says chronic kidney disease is common, often has no symptoms early on, and may only be found on a blood or urine test. Because kidney disease changes what is safe, extra protein or supplements should be agreed with your kidney team.

Who it applies to: People with known or suspected kidney problems, long-standing diabetes or high blood pressure, and older adults.

Try instead: Ask your doctor, kidney nurse or a registered dietitian what level of protein suits you.

⁴

Products that need caution

High-dose vitamin C and vitamin E supplements around training

Low certainty

Why: In a controlled trial of 39 healthy young men, taking vitamin C and vitamin E supplements during 4 weeks of exercise training blocked some of the usual improvements, including in insulin sensitivity. It is a small trial and did not measure muscle soreness, but the authors suggest high-dose antioxidant supplements may blunt the benefits of exercise.

Who it applies to: People taking antioxidant supplements to "reduce inflammation" or speed recovery.

Try instead: Get vitamins C and E from fruit, vegetables, nuts and seeds, and check with a pharmacist before taking supplements.

^23,5

Vitamin C →

Multi-ingredient recovery powders and pre-made shakes used instead of meals

Moderate certainty

Why: The ISSN suggests whole foods first, and the NHS says most people get the nutrients they need from a varied diet. The effect of protein supplements in the largest meta-analysis was small on average (about 0.3 kg of extra lean mass over training periods).

Who it applies to: People who add protein powder to a diet that already contains enough protein.

Try instead: Use a powder only when food is hard to get, and check the label for what it contains. In tested sport, check anti-doping rules.

^7,8,5

Protein powder → Whey protein →

Unsupported claims

"You must eat protein within 30 minutes or the workout is wasted"

Moderate certainty

Why: The ISSN says post-exercise protein within about 2 hours raises muscle protein synthesis, that the anabolic effect of exercise lasts at least 24 hours, and that the best timing is likely a matter of individual tolerance. The sources we read do not describe a 30-minute cut-off.

Who it applies to: Gym marketing and supplement labels.

Try instead: Hit your daily protein total and have a meal within a couple of hours if your next session is soon.

^2,7

"You need a sports drink after every workout"

Moderate certainty

Why: The American College of Sports Medicine says electrolyte and carbohydrate drinks can have benefits over water in certain circumstances, and the NHS says water is the best way to replace fluid lost in physical activity. Short, easy workouts do not usually need them.

Who it applies to: Ads and gym culture.

Try instead: Use water and a normal meal for short sessions, and consider other drinks only for long, hot or repeated sessions.

^9,11

"Detox" or "alkalising" recovery drinks flush out toxins

Not enough evidence

Why: We did not find any human trial evidence in the sources we read that such drinks speed recovery. The NHS describes fluid and balanced food as the basis for hydration.

Who it applies to: Product labels and social media.

Try instead: Rely on food, fluids and rest.

¹¹

Common mistakes

Skipping meals after training because you are not hungry or because you want to lose weight

Moderate certainty

Why: The IOC consensus describes harm from too little energy for the exercise done, and the ISSN stresses meeting daily protein, spread through the day. Appetite can be low after hard exercise, so small, easy foods help.

Who it applies to: Anyone who trains late, in the heat or when dieting.

Try instead: Try a yogurt, banana, milk, sandwich or smoothie, then a proper meal when appetite returns.

^3,2

Using supplements to cover for poor sleep, rest or too much training

Moderate certainty

Why: The studies on soreness and recovery supplements measure small differences, and the reviews call the evidence low or mixed. Nutrition supports but does not replace rest.

Who it applies to: People who keep adding products when they feel run down.

Try instead: Look at rest days, sleep and training load first, then food, then supplements if you still want them.

Evidence & safety

What the research shows

The most reliable advice is also the plainest: eat enough, include protein through the day, refuel with carbohydrate when you must train again soon, and replace fluids. These come from position statements and consensus reports from sports-nutrition and medical bodies and from a large meta-analysis of protein supplements. Evidence for recovery foods and supplements such as tart cherry, curcumin, omega-3, BCAA and creatine is smaller and less certain, and we did not find evidence that any of them speeds the repair of muscle tissue itself.

Limits of the evidence

Many recovery studies are small, short, in young trained men and measure soreness or blood markers rather than how well people actually train later.
Reviews of the same supplement sometimes disagree (curcumin and omega-3), and a 2026 network meta-analysis rated the certainty of plant supplement evidence as generally low.
Position statements are expert consensus built on research that is partly from elite or highly trained athletes; effects in casual exercisers may differ.
We could not read full texts of the studies and relied on abstracts and agency pages.

Precautions and interactions

Supplements can interact with medicines; check with a pharmacist, especially if you take regular medicines or have kidney or liver conditions or diabetes.
Do not raise protein or take creatine without advice if you have kidney disease.
High-dose antioxidant vitamin supplements may blunt some training adaptations.
If you compete in tested sport, check anti-doping rules before using any supplement.

Life-stage considerations

Pregnancy and breastfeeding: needs and cautions differ; ask your midwife, doctor or dietitian before using recovery supplements. The NHS says to have no more than 200 mg of caffeine a day in pregnancy.
Children and teenagers: young athletes need enough energy for growth; supplements should not be used without medical advice.
Older adults: protein supplements had smaller effects on lean mass with increasing age in a meta-analysis, and older adults dehydrate more easily, so food, fluids and advice from a clinician matter.

Warning signs

Dark urine with severe muscle pain or weakness after exercise.
Ongoing dizziness, confusion, fast breathing or very little urine.
Weeks of tiredness or falling performance despite rest and enough food.
Unplanned weight loss, repeated injuries, or fear of eating.

Claim checks

Tart cherry juice speeds recovery

Low certainty

A meta-analysis found small to moderate benefits for soreness and strength recovery, and a network meta-analysis found it eased soreness most consistently but did not clearly change strength or blood markers, with low certainty. It may ease soreness; we did not find that it speeds repair.

^14,15

Chocolate milk is the best recovery drink

Low certainty

A systematic review of 12 trials found chocolate milk did as well as or better than water or other recovery drinks on some measures, with no effect on most, and called the evidence limited.

¹³

You need extra protein supplements to recover

Moderate certainty

Daily protein totals matter, and supplements gave a small average gain in strength and lean mass in resistance-training trials, but whole foods can supply what most people need.

^8,7

Antioxidant vitamins reduce inflammation and make recovery faster

Evidence against

We did not find evidence of faster recovery. A controlled trial of 39 men found that vitamin C and E supplements blocked some training adaptations.

²³

Fish oil prevents sore muscles

Mixed findings

Reviews conflict. One found a reduction too small to be meaningful; another found benefits in a subset of studies but called the literature equivocal with serious limitations.

Questions people ask

What should I eat after a workout?

A meal or snack with carbohydrate and a protein food is a sensible choice, such as yogurt with fruit, eggs on toast, a sandwich or rice with fish or beans. The ISSN says faster refuelling matters most when you will train hard again in under 4 hours, and that meeting your total daily protein, spread through the day, is a primary focus.

How much protein do I need for recovery?

The ISSN position stand says about 1.4 to 2.0 g of protein per kg of body weight a day is enough for most exercising people, spread through the day. Your own needs depend on your age, health and training; people with kidney disease should ask their kidney team, and a registered dietitian can set a personal level.

Do I need to eat within 30 minutes of exercising?

We did not find a 30-minute cut-off in the sources we read. The ISSN says protein eaten up to about 2 hours after exercise raises muscle protein synthesis and that the effect of a workout lasts at least 24 hours, so your daily total and regular meals matter more than exact minutes.

How much should I drink after exercise?

There is no single amount. The American College of Sports Medicine suggests weighing yourself before and after exercise to see your sweat loss, and a review says to drink more than you lost, steadily and with some salt. The NHS says to aim for pale yellow pee and to drink extra when you sweat.

Is chocolate milk a good recovery drink?

It is a reasonable option if you tolerate milk. Milk kept more fluid in the body than water in one trial of 72 men, and a review of 12 trials found chocolate milk did as well as or better than other drinks on some measures, but called the evidence limited. It contains added sugar.

Does tart cherry juice work for sore muscles?

It may ease soreness a little. A meta-analysis found small to moderate benefits and a 2026 network meta-analysis found it was the most consistent plant supplement for soreness, though the certainty was low and strength and blood markers did not clearly change.

Should I take BCAA, creatine or fish oil to recover faster?

The evidence is mixed. BCAA may lessen soreness in trained people. Creatine has strong evidence for high-intensity performance and some support for recovery. Fish oil reviews disagree. If you eat enough protein, supplements add little for most people, and you should check for medicine interactions first.

Do vitamin C and E supplements help recovery?

We did not find evidence that they help. In a controlled trial of 39 young men, vitamin C and E supplements blocked some of the benefits of 4 weeks of exercise training. Getting these vitamins from fruit, vegetables, nuts and seeds is a safer way.

Can I recover on a vegetarian or vegan diet?

Yes, with planning. The ISSN says it is the essential amino acids that stimulate muscle building, so a variety of protein sources helps. Beans, lentils, soya foods, nuts and seeds, and fortified dairy alternatives can help; ask a dietitian about iron and vitamin B12.

When is tiredness after exercise not normal?

Feeling tired after hard exercise is normal, but weeks of tiredness, falling performance, unplanned weight loss or repeated injuries are not. See a doctor or registered dietitian. Dark urine with severe muscle pain needs urgent medical care.
