Orange juice.

Orange Juice

Citrus sinensis (the fruit it is made from) · also called OJ, 100% orange juice, jugo de naranja (Spanish)

Orange juice is the liquid pressed from sweet oranges. One cup has about 84 mg of vitamin C, but also about 21 g of sugars and almost no fibre. Trials show small changes in cholesterol, and cohort studies link fruit juice with slightly higher diabetes risk. The main cautions are sugar, potassium in kidney disease, a few medicines such as fexofenadine, and untreated fresh-squeezed juice.

About Orange Juice

Orange juice is a dependable source of vitamin C, with potassium and folate. It is also a sugary drink with little fibre. Trials show small, inconsistent changes in cholesterol, so it is best seen as a drink for pleasure and vitamin C, not a remedy.

What it is

Orange juice is the liquid pressed from sweet oranges (Citrus sinensis). It is sold fresh-squeezed, chilled from concentrate, or as "not from concentrate" in cartons. Some juice is pasteurized or otherwise treated and some is not.

One cup (249 g) of chilled juice provides about 122 calories, 20.7 g of sugars, 0.7 g of fibre, 84 mg of vitamin C, 443 mg of potassium and 47 mcg of folate (USDA FoodData Central). Fortified and fresh-squeezed juices differ.

What the research shows

Three pooled analyses of randomised trials found small falls in LDL or total cholesterol with orange juice. They disagree on which markers moved. One analysis in overweight adults found blood pressure about 1 mmHg lower.

In three large US cohorts, fruit juice went with a slightly higher risk of type 2 diabetes, while whole oranges showed no clear link. For 100% fruit juice, children's cohort studies show a very small higher BMI change per daily serving, and adult trials show no significant weight change.

Hesperidin, a citrus plant compound, did not change cholesterol or blood pressure when taken as a supplement.

Juice versus whole orange and supplements

A whole orange keeps its fibre; juice mostly does not. In diabetes studies, fruit juice and whole oranges did not show the same pattern.

Cholesterol results are for the juice. Hesperidin tablets are a different product, and in pooled trials they did not change cholesterol or blood pressure.

A 2026 symposium report argues juice should count as a processed fruit rather than a sugar-sweetened drink. It was sponsored by a fruit juice research body, so we mention it only to show the debate exists.

Isolated compounds versus whole extracts

The cholesterol results are for juice. Hesperidin supplements, tested on their own, did not change cholesterol or blood pressure. Whole oranges keep their fibre, which juice mostly lacks, and in diabetes cohort studies fruit juice and whole oranges did not show the same pattern. A 2026 sponsored symposium report argues juice should count as processed fruit, not a sugar-sweetened drink; it was sponsored by a fruit juice research body and is used here only to show the debate exists.

Nutritional composition

Per 100 g of chilled orange juice, including from concentrate (USDA FoodData Central, SR Legacy record 169100): 49 kcal, 8.3 g sugars, 11.5 g carbohydrate, 0.3 g fibre and 0.68 g protein. One cup (249 g, about 8 fl oz) provides about 122 kcal, 20.7 g sugars, 0.7 g fibre, 84 mg vitamin C (close to the whole Daily Value), 47 mcg folate and 443 mg potassium. Freshly pressed juice, not-from-concentrate juice and fortified juice differ; some cartons add calcium and vitamin D. Per-cup figures are the per-100 g values multiplied by 2.49. These numbers were carried over from the USDA record cited earlier and were not re-opened for this page. Values vary with brand, fortification and storage.

What is Orange Juice good for?

The main studied uses and how strong the human evidence is for each. Most results are small changes in lab markers or links seen in eating habits, not proof that orange juice prevents or treats a disease.

Vitamin C from the drinkHigh certaintyOne cup of chilled orange juice has about 84 mg of vitamin C, close to the whole Daily Value. This is a nutrient fact, not proof that extra vitamin C prevents illness. Blood cholesterol (orange juice trials)Low certaintyPooled trials found LDL about 8 to 9 mg/dL lower in two analyses, and a third found total cholesterol lower but no clear LDL change. Effects are small and the analyses disagree. Blood pressure, blood sugar and inflammation markersLow certaintyOne analysis found about 1 mmHg lower systolic blood pressure; another found small falls in glucose, insulin and an inflammation marker; a third found no clear effect. Results are small and inconsistent. Type 2 diabetes riskVery low certaintyIn three US cohorts of health professionals, more fruit juice went with a slightly higher diabetes risk (HR 1.08 per 3 servings a week). Whole oranges showed no clear link. A link is not proof of cause. Body weightLow certaintyFor 100% fruit juice of any kind, children's cohort studies show a very small higher BMI change per daily serving. Adult trials found no significant weight change. Flavanones (citrus plant compounds) and heart healthVery low certaintyCohort studies link higher intake of citrus flavanones with lower heart disease, but hesperidin supplement pills did not change cholesterol or blood pressure in pooled trials. Preventing colds, heart attacks, cancer or other diseaseNot enough evidenceWe did not find a pooled trial showing that orange juice prevents heart attacks, cancer or colds. MedlinePlus says vitamin C does not reduce the chance of getting a cold in most people.

Vitamin C from the drink

High certainty

One cup of chilled orange juice supplies about 84 mg of vitamin C, which is close to the whole Daily Value. This is the main thing the drink is good for, and it is a nutrient fact rather than a trial result.

2 studiesChilled orange juice as a drink. Fresh-squeezed juice and fortified j…

Studies, doses and limits

What the trials found

MedlinePlus lists citrus fruits and juices such as orange among the richest sources of vitamin C. The USDA record gives the amount per cup.

Results

About 84 mg per cup of chilled juice (carried over from the USDA record; see notes). MedlinePlus says light can lower vitamin C, so juice in a carton keeps it better than a clear bottle.

Effect sizes as reported

Per cup: about 84 mg, roughly 93% of the Daily Value (as printed from the USDA record).

Why this rating

This is a food-composition fact backed by a government encyclopedia, not a trial. The exact USDA figures were carried over and not re-opened.

Form and dose studied

Chilled orange juice as a drink. Fresh-squeezed juice and fortified juice differ.

Who was studied

General population.

Limits

Getting enough vitamin C from food is not the same as proof that extra prevents colds or other illness. MedlinePlus says vitamin C does not reduce the chance of getting a cold in most people.

Why researchers looked

Orange juice is one of the most common sources of vitamin C in many diets.

Proposed mechanism Established nutrition

Vitamin C helps form collagen and helps the body absorb iron. It is an essential vitamin.

A proposed mechanism does not show that the effect happens in people.

Very high vitamin C intakes from supplements are a different matter (see Safety).

Blood cholesterol (orange juice trials)

Low certainty

Pooled trials of orange juice found small changes in blood cholesterol. LDL (the so-called bad cholesterol) fell by about 8 to 9 mg/dL in two analyses. A third found a fall in total cholesterol but not in LDL. The results differ between analyses and the trials were short.

3 studiesOrange juice as a drink. About 500 ml a day was where larger effects …

Studies, doses and limits

What the trials found

A 2023 pooled analysis of 9 randomised trials found LDL 8.35 mg/dL lower. A 2022 analysis of 10 trials found LDL 9.14 and total cholesterol 9.84 mg/dL lower. A 2021 analysis of 15 trials found total cholesterol 6.84 mg/dL lower but no clear LDL change.

Results

Small falls in LDL and total cholesterol in some analyses, no clear change in HDL or triglycerides in two of three. The authors of the 2023 analysis suggest intake above 500 ml a day might be what matters and ask for better trials.

Effect sizes as reported

LDL: -8.35 mg/dL (95% CI -15.43 to -1.26, 9 trials); -9.14 mg/dL (-15.79 to -2.49, 10 trials). Total cholesterol: -6.84 (-12.38 to -1.29, 15-trial analysis); -9.84 (-15.43 to -4.24).

Why this rating

The three analyses overlap in the trials they pooled and disagree on which markers moved. Small effects, short trials, and the authors of one call the evidence low to moderate quality. Blood markers only, no heart outcomes.

Form and dose studied

Orange juice as a drink. About 500 ml a day was where larger effects appeared in subgroup results, which is a lot of sugar (see Safety). This is not advice.

Who was studied

Adults in randomised trials.

Limits

Marker only; no study shows fewer heart attacks. Trials differ in amount and length.

Why researchers looked

Orange juice contains flavanones such as hesperidin, which might affect blood fats.

Proposed mechanism Preliminary mechanism

Flavanones and fibre-like pectin have been suggested as routes. Not shown in these analyses.

A proposed mechanism does not show that the effect happens in people.

A large daily amount means a lot of sugar and calories.

^{2 1 11}

Blood pressure, blood sugar and inflammation markers

Low certainty

Trial analyses disagree. One found about 1 mmHg lower systolic blood pressure in overweight adults. One found small falls in glucose, insulin and an inflammation marker (C-reactive protein). Another found no clear effect on these. The changes are small and not consistent.

Studies, doses and limits

What the trials found

A 2022 analysis of 8 trials in overweight adults found systolic blood pressure -0.98 mmHg. A 2022 analysis of 10 trials found lower glucose (-2.92 mg/dL), insulin and C-reactive protein. A 2021 analysis of 15 trials found a lower insulin-resistance score (HOMA-IR) but no clear effect on other markers, including blood pressure.

Results

Small, inconsistent changes. A fall of about 1 mmHg in blood pressure is very small.

Effect sizes as reported

Systolic blood pressure -0.98 mmHg (95% CI -1.52 to -0.44); glucose -2.92 mg/dL (-5.33 to -0.53); CRP -0.467 mg/L (-0.815 to -0.120); HOMA-IR -0.39 (-0.77 to -0.006).

Why this rating

The analyses disagree on which markers moved, overlap in the trials they pool, and are short. Markers only.

Form and dose studied

Orange juice as a drink. Larger daily amounts (500 ml or more) appeared in subgroup results of one analysis.

Who was studied

Adults in randomised trials, including overweight and obese adults.

Limits

Markers only. Whether any change matters for health is unknown. Observational studies point the other way for diabetes risk (see the diabetes entry).

Why researchers looked

Orange juice has flavanones and vitamin C, which might affect blood vessels and inflammation.

Proposed mechanism Unknown

Not established.

A proposed mechanism does not show that the effect happens in people.

Juice has about 21 g of sugars per cup; people watching blood sugar should ask their care team.

^{9 1 11}

Type 2 diabetes risk

Very low certainty

In three large US studies of health professionals followed for years, drinking more fruit juice went with a slightly higher chance of developing type 2 diabetes. Eating whole oranges showed no clear link either way. This is a link in eating habits, not proof that juice causes diabetes.

1 studiesFruit juice in general, as drunk.

Studies, doses and limits

What the trials found

A 2013 BMJ analysis pooled three cohorts (about 187,000 people). Per 3 servings a week, fruit juice had a hazard ratio of 1.08 for type 2 diabetes. Oranges: 0.99. The juice figure covers fruit juice as a whole, not orange juice alone.

Results

Slightly higher risk with more fruit juice; whole oranges neutral.

Effect sizes as reported

Fruit juice HR 1.08 (95% CI 1.05 to 1.11) per 3 servings a week; oranges HR 0.99 (0.95 to 1.03).

Why this rating

Observational. People who drink more juice may differ in other ways. The juice finding is for fruit juice in general. Participants were health professionals in the US.

Form and dose studied

Fruit juice in general, as drunk.

Who was studied

Health professionals in the US, followed 1984 to 2009.

Limits

Link, not cause. Not orange-juice specific.

Why researchers looked

Juice is a source of sugar with little fibre, so researchers have asked whether it differs from whole fruit.

Proposed mechanism Unknown

Not established.

A proposed mechanism does not show that the effect happens in people.

People with diabetes should ask their care team how juice fits into their plan.

¹²

Body weight

Low certainty

Studies of 100% fruit juice and weight are mixed. In children, each extra daily serving went with a very small higher BMI change in cohort studies. In adults, cohort results depended on whether energy intake was accounted for, and trials found no significant weight change.

1 studies100% fruit juice, a serving a day.

Studies, doses and limits

What the trials found

A 2024 analysis of 42 studies (17 child cohorts, 6 adult cohorts, 19 adult trials) looked at 100% fruit juice of any kind.

Results

Children: BMI change 0.03 higher per daily serving. Adults: cohorts unadjusted for energy showed 0.21 kg gain, adjusted showed -0.08 kg; trials -0.53 kg with a wide range that includes no change.

Effect sizes as reported

Children 0.03 BMI (95% CI 0.01 to 0.05); adult RCTs -0.53 kg (95% CI -1.55 to 0.48).

Why this rating

Mixed results; cohort studies cannot show cause; trials in adults were compared with no-calorie drinks. All 100% juices pooled, not orange juice alone.

Form and dose studied

100% fruit juice, a serving a day.

Who was studied

Children and adults.

Limits

No trials in children. Not orange-juice specific.

Why researchers looked

Juice adds calories without much fibre, so researchers have asked whether it adds to weight gain.

Proposed mechanism Unknown

Not established.

A proposed mechanism does not show that the effect happens in people.

None specific.

¹³

Flavanones (citrus plant compounds) and heart health

Very low certainty

Citrus fruits are rich in compounds called flavanones, such as hesperidin. A 2026 review of reviews links higher flavanone intake with lower heart disease and stroke in cohort studies. Hesperidin supplement pills, tested on their own, did not change cholesterol or blood pressure.

2 studiesFlavanones from foods and supplements (review); hesperidin supplement…

Studies, doses and limits

What the trials found

A 2026 review of 25 meta-analyses reported 12% to 22% lower relative risk of cardiovascular disease and 12% to 26% for stroke with higher flavanone intake, and favourable trial effects on cholesterol, blood pressure, glucose and CRP. A 2019 analysis of 10 trials (577 people) found hesperidin supplements had no effect on cholesterol, triglycerides or blood pressure.

Results

Cohort studies link flavanones with lower risk; hesperidin pills did not change markers.

Effect sizes as reported

Flavanones: relative risk reductions 12-22% (cardiovascular disease), 12-26% (stroke). Hesperidin supplements: total cholesterol -1.04 mg/dL (95% CI -5.65 to 3.57); systolic BP -0.85 mmHg (-3.07 to 1.36).

Why this rating

A review of reviews with mixed foods and supplements, whose authors urge caution. Flavanone intake is not the same as drinking orange juice. The supplement analysis is evidence against hesperidin pills.

Form and dose studied

Flavanones from foods and supplements (review); hesperidin supplements (trials). Neither is juice.

Who was studied

Adults in cohorts and trials.

Limits

Does not separate orange juice from other sources.

Why researchers looked

Flavanones are among the main plant compounds in orange juice.

Proposed mechanism Preliminary mechanism

Antioxidant and blood-vessel effects are suggested, mostly from lab work; not tested here.

A proposed mechanism does not show that the effect happens in people.

None specific.

Very little or very weak human data. Treat as a possibility only.

Mixed findings

Trials or reviews disagree with each other.

Not enough evidence

Not enough human research to say either way.

Evidence against

Good research found no benefit, or found harm.

We take the reviewers' own risk-of-bias and GRADE statements where they exist, and otherwise judge from study size, design, consistency, directness and whether a product matches what is sold. Many publications do not make evidence high. Method note: We started from our earlier orange juice summary, re-read the PubMed abstracts and the FDA, NIDDK, NHS, MedlinePlus and WHO pages. The USDA nutrient numbers were carried over and not re-opened. Only abstracts were read for studies. Items we could not verify are listed in the research gaps.

What we do not know yet

No trial has tested orange juice for heart attacks, stroke, diabetes or cancer outcomes.
The cholesterol analyses pool overlapping trials and disagree on which markers moved.
Most diabetes and weight data cover fruit juice in general, not orange juice alone.
Allergy to citrus, pesticide and metal testing, acid reflux and pregnancy advice beyond the FDA and MedlinePlus statements were not researched.
The USDA record was not re-opened for this page because the service was rate-limited; the nutrient numbers are carried over.

Safety

What studies and official sources say about side effects, medicines and who should check first. Each point shows what kind of evidence it comes from.

Main points to know 4

Fresh-squeezed juice that is not pasteurized can carry harmful bacteria. The FDA says juice made from raw produce can be contaminated unless it has been pasteurized or otherwise treated. Children, older adults, pregnant women and people with weakened immune systems risk serious illness, or even death, from untreated juice. Packaged untreated juice must carry a warning label, but juice sold by the glass (for example at juice bars or farmers' markets) does not need one. Authoritative guidance ¹⁵
It is a sugary drink, even with no sugar added. One cup has about 21 g of sugars and about 122 kcal, with almost no fibre (USDA values carried over; see notes). The WHO says most fruit juices, including those with no added sugar, contain significant free sugars, which should be limited. The NHS counts juice as at most one 5 A DAY portion, with a combined limit of 150 ml a day for juice, vegetable juice and smoothies, and says the sugars released by juicing can damage teeth. Authoritative guidance ^{19 20 17}
Potassium: people with kidney disease may need to limit orange juice. The NIDDK says damaged kidneys can struggle to remove potassium. For people who must limit it, it suggests apple, grape or cranberry juice rather than higher-potassium juices such as orange juice. One cup has about 443 mg of potassium (USDA values carried over). Ask your care team. Authoritative guidance ^{18 19}
Some medicines are absorbed less well with orange juice. The FDA says the allergy medicine fexofenadine (Allegra) may not work as well with orange or apple juice, and its label says not to take it with fruit juices. A 2019 review of 46 trials also lists orange juice with lower absorption of aliskiren, atenolol, celiprolol, montelukast, fluoroquinolone antibiotics and alendronate. A pharmacist can check your own medicines. Authoritative guidance and trial review ^{14 4 3 6}

Side effects 3

Effect	How often	Severity and recovery	Evidence
Tooth decay with frequent juice The NHS says to drink juice with meals. The AAP says juice sugar adds to the risk of tooth decay.	Not established	mild to moderate Damage to enamel is not reversible; early decay can be treated by a dentist.	Authoritative guidance ^{17 7}
Food poisoning from untreated juice FDA says outbreaks have been traced to untreated juice. No frequency is given in the page read.	Not established	mild to severe Varies	Authoritative guidance ¹⁵
Stomach upset and diarrhoea from very high vitamin C intake MedlinePlus puts this at amounts above 2,000 mg a day, mostly from supplements. A cup of juice is far below that.	Not established	mild Settles when intake falls	Authoritative guidance ¹⁶

Liver

No liver injury linked to drinking orange juice was found in the sources read. LiverTox was not checked.

How often. No frequency found.

This is a safety connection. It is not evidence that Orange Juice supports liver health.

Medicines and supplements 4

With	Why it matters	Importance	Evidence	What to do
Fexofenadine (Allegra, an allergy medicine) prescription and over-the-counter	Juice may block uptake transporters in the gut, so less drug is absorbed.	The FDA and the label say it may work less well with orange or apple juice. Reviews say the clinical importance is not clearly established and that spacing juice and drug apart reduces the effect.	Authoritative guidance, trials and reviews Moderate certainty ^{14 3 6}	Follow the medicine label. A pharmacist can advise on timing.
Other medicines whose absorption fell with orange juice in trials (aliskiren, atenolol, celiprolol, montelukast, fluoroquinolone antibiotics, alendronate) prescription	Reduced absorption, described in trials.	A review of 46 trials lists these as potential adverse interactions. The abstract does not give the size of each effect, and it says juices other than grapefruit did not cause the severe interactions seen with grapefruit.	Trial review Low certainty ^{4 3}	Ask a pharmacist how to time juice and these medicines.
Grapefruit-type interaction (statins, some blood pressure and heart-rhythm medicines) prescription	Applies to grapefruit juice, Seville oranges, pomelos and tangelos.	The FDA page lists Seville oranges, pomelos and tangelos as possibly acting like grapefruit juice and does not list regular orange juice as a general problem. Marmalade made from Seville oranges is a different product.	Authoritative guidance Moderate certainty ¹⁴	Check the label that your juice is 100% sweet orange and not mixed with grapefruit.
Potassium-limiting treatment in kidney disease condition-related	Orange juice is relatively high in potassium.	NIDDK names it as a juice higher in potassium than apple, grape or cranberry juice.	Authoritative guidance Moderate certainty ¹⁸	Follow your dietitian's plan.

Who should check first 3

Situation	Advice	Evidence
Advanced kidney disease on a potassium limit	Ask your care team before drinking orange juice; NIDDK suggests lower-potassium juices.	Authoritative guidance ¹⁸
Pregnancy, older age, weak immune system, or children, with unpasteurized juice	Choose pasteurized or otherwise treated juice (FDA).	Authoritative guidance ¹⁵
Taking fexofenadine (Allegra)	Do not take with fruit juices, per the label quoted by the FDA.	Authoritative guidance ¹⁴

Overdose, product quality and regulators

Summary. Pasteurized orange juice is an ordinary drink. The concerns in the sources read are sugar, potassium for people with kidney disease, medicine interactions and bacteria in untreated juice.

Animal. Not reviewed.

Human doses studied. Trials gave orange juice for weeks and the abstracts read mention no safety problem.

High dose or long term signals. Observational studies link much fruit juice with slightly higher diabetes risk and weight gain (see Benefits).

Overdose response. Not found.

Genotoxicity. Not reviewed.

The main concern in the sources read is bacteria in untreated, fresh-squeezed juice. Pesticide and metal testing for orange juice was not researched.

Bacteria in untreated juice. FDA says juice from raw produce can be contaminated unless pasteurized or treated, and outbreaks have been traced to untreated juice and cider. ¹⁵

When to get medical help

Swelling of the lips, face, tongue or throat after drinking it
Trouble breathing or wheezing
Fever, bloody diarrhoea, severe vomiting or stomach pain after untreated juice
Muscle weakness or an irregular heartbeat in someone with kidney disease (NIDDK says too much potassium can cause heart and muscle problems); seek urgent care

Frequently asked questions

What is orange juice good for?

It is a reliable source of vitamin C: about 84 mg per cup, close to the whole Daily Value. It also has potassium and folate. It is also a sugary drink with little fibre.

^{19 16}

Does orange juice lower cholesterol?

Three pooled analyses of trials found small falls in LDL or total cholesterol, about 6 to 10 mg/dL, but they disagree on which markers moved and the effects are small. No study shows fewer heart attacks.

^{2 1 11}

Does orange juice affect blood pressure?

One analysis of 8 trials in overweight adults found systolic blood pressure about 1 mmHg lower. Another analysis of 15 trials found no clear effect. The change is very small.

^{9 11}

Is orange juice bad for diabetes or blood sugar?

One cup has about 21 g of sugars. In three US cohorts of health professionals, more fruit juice went with a slightly higher chance of type 2 diabetes (HR 1.08 per 3 servings a week), though that cannot prove cause. People with diabetes should ask their care team.

^{19 12}

Does orange juice make you gain weight?

Studies of 100% fruit juice are mixed. In children, each extra daily serving went with a very small higher BMI change in cohorts. Adult trials found no significant weight change. These results cover fruit juice in general.

¹³

Is orange juice as healthy as a whole orange?

They are different. Juice mostly lacks the fibre of the whole fruit, and in diabetes studies juice and whole oranges did not show the same pattern. Some groups argue juice is closer to fruit than to soda, but the report we read was sponsored by a juice research body.

^{12 8 20}

Does orange juice prevent colds?

No pooled trial of orange juice was found for this. MedlinePlus says vitamin C supplements or vitamin C-rich foods do not reduce the risk of getting a cold in most people.

¹⁶

Is orange juice bad for your teeth?

The NHS says juicing releases sugars that can damage teeth and advises drinking juice with meals, not between meals. The American Academy of Pediatrics also notes juice sugar adds to tooth decay risk.

^{17 7}

Can people with kidney disease drink orange juice?

Ask your care team. The NIDDK says damaged kidneys can struggle to remove potassium and names orange juice as higher in potassium than apple, grape or cranberry juice. One cup has about 443 mg.

^{18 19}

Does orange juice interact with medicines?

The FDA says the allergy medicine fexofenadine may not work as well with orange or apple juice. A review of trials also lists lower absorption of some other medicines. This is separate from the grapefruit warning, which the FDA does not extend to regular orange juice. A pharmacist can check your medicines.

^{14 4 3}

Is fresh-squeezed orange juice safe?

The FDA says untreated juice can carry harmful bacteria. Children, older adults, pregnant women and people with weak immune systems are at higher risk, so pasteurized juice is the safer choice. Packaged untreated juice must carry a warning label, but juice sold by the glass does not.

¹⁵

Is orange juice safe in pregnancy?

Pasteurized juice is the safer choice, because the FDA names pregnant women as higher risk from untreated juice. MedlinePlus says large vitamin C supplement doses are not recommended in pregnancy. No other pregnancy advice specific to orange juice was found.
