Adaptogens by Wellness Goal

A plain-language index of what research and health agencies say adaptogens may or may not do for stress, energy, sleep, focus and exercise, with links to each goal page.

Content last updated . This page has not been medically reviewed.

Safety first. Natural products can cause side effects and interact with medicines. Read who should be careful, by situation before you use anything on this page.

If you feel overwhelmed, hopeless or unsafe, do not start with a supplement. In the US you can call or text 988 (Suicide & Crisis Lifeline), available 24 hours a day, or call 911 in an emergency. [1] Long-lasting tiredness, poor sleep or anxiety have many causes, and a clinician can look for them.

People usually come to adaptogens with a goal: less stress, more energy, better sleep, a clearer head, better workouts. This page is the map. For each goal it says in one line what the sources we read found, labels how strong that evidence is, and sends you to the page with the detail.

"Adaptogen" is a contested word. NCCIH (part of the US National Institutes of Health) describes adaptogenic herbs as ones thought to help the body resist physical and psychological stress. [2] Researchers define it in their own words, and which plants count is a question each page answers from its sources, not a given. How the idea started and why definitions differ are covered in What are adaptogens?.

The five main goals at a glance

GoalWhat the sources we read foundEvidence labelDetail
Stress, anxiety, resilienceNCCIH says some ashwagandha (Withania somnifera) preparations may be effective for stress but evidence on anxiety is unclear. [3] For rhodiola (Rhodiola rosea) it finds not enough reliable evidence for any purpose. [4]Promising but limited (ashwagandha); insufficient evidence (rhodiola)Stress, anxiety and resilience
Energy and fatigueA 2023 review of ginseng trials found no significant fatigue reduction overall, but a benefit in some subgroups. [5] NCCIH notes not all research agrees. [2]MixedEnergy and fatigue
Sleep and relaxationNCCIH says some ashwagandha preparations may be effective for insomnia. [3] A 2021 meta-analysis of five trials (400 adults) found a small effect on sleep. [6]Promising but limitedSleep and relaxation
Focus and mental performanceA 2024 meta-analysis of ginseng found an effect on memory but not on overall cognition, attention or executive function. [7] NCCIH finds not enough evidence for ashwagandha and cognitive function. [3]MixedFocus and mental performance
Exercise performance and recoveryNCCIH says the majority of research shows Asian ginseng does not improve athletic performance. [2] Two meta-analyses of rhodiola reached different conclusions on endurance. [8][9]MixedExercise and recovery

More goals and questions

These pages go deeper on related questions. Each one is its own guide, so we do not repeat their findings here.

How to read the labels

We use the same words on every goal page: established, promising but limited, mixed, insufficient evidence, no good evidence of benefit, evidence of harm, preclinical (cells or animals), traditional use only and marketing claim. Where we searched and found nothing usable, we write "Proper evidence not found" and say what we searched.

Three cautions apply to every row above:


  • A result for one plant part, extract or amount does not carry over to another. Ashwagandha, Asian ginseng (Panax ginseng) and rhodiola are different plants. NCCIH lists "Indian ginseng" as a common name for ashwagandha, [3] yet GBIF files ashwagandha in the nightshade family (Solanaceae) and Panax ginseng in the Araliaceae family. [10][11]

  • A change in a lab marker, such as cortisol, is not the same as feeling better or functioning better. See How stress, fatigue and sleep are measured.

  • Research findings are not instructions. A clinician or pharmacist decides what is right for a person.

Frequently asked questions

Which adaptogen is best for my goal?

We do not rank products or plants. The sources describe different plants, extracts and study groups, so there is no universal winner, and for most goals the human evidence is limited or mixed. [2][4]

Do adaptogens lower cortisol?

A 2026 meta-analysis reported lower blood cortisol with ashwagandha in 23 trials, but cortisol is a lab marker and the authors note heterogeneity. [12] Whether that means a person copes better is a separate question. See Adrenal fatigue and adrenal support claims.

Why do NCCIH and recent reviews sometimes sound different?

NCCIH pages summarize the evidence at a point in time and stress small studies and varied preparations. [3] Newer reviews pool newer trials but still report differences between studies. [13]

Can I use adaptogens instead of treatment for anxiety, depression or insomnia?

Proper evidence not found that they replace treatment. We read the NCCIH pages and PubMed reviews listed below on 2026-10-23 and none presents an adaptogen as a substitute for care. Ask a clinician, and see adaptogens and mental health conditions.

What if my tiredness or poor sleep does not go away?

See a health professional. The NHS lists sleep problems, stress, depression and several medical conditions among causes of tiredness. [14]

Safety before goals
Supplements can interact with medicines. NCCIH lists medicines for diabetes and high blood pressure, immunosuppressants, sedatives, anti-seizure medicines and thyroid hormone medicines among those ashwagandha might interact with. [3] Tell your prescriber or pharmacist about every supplement, including before surgery, and see how medicine interactions work and Adaptogen safety and interactions. For wider, non-supplement approaches to the same goals, see Stress & Relaxation, Energy & Vitality, Better Sleep and Focus & Memory.
