What the Word Means, What Research Shows & What to Check Before You Use.
Adaptogen is a traditional and Soviet-era idea, not a medical category. Explore each plant, root, mushroom and berry that is often called one: where it comes from, what studies in people have and have not found (and what was only in the lab), and what to check before you use it: stimulation and sleep, thyroid, autoimmune disease, pregnancy, blood thinners, blood pressure, diabetes medicines, liver and hormone-sensitive conditions.
Four quick questions. We show you where to start and what to do next. It takes about a minute.

No adaptogen matches all of these filters. Try removing one. Some topics (for example most herbs) are not adaptogens and live elsewhere on the site.
"Adaptogen" is a traditional and Soviet-era idea, not a medical category, and European regulators judge each herb on its own evidence rather than on that word. "Studied for" means a study in people exists, not that the plant works: most trials are small, short and often paid for by makers. "Check before you use" lists cautions a source we read raised. It is not a complete list, so ask a pharmacist or clinician if you take medicines or have a health condition.
A link between a adaptogen and a topic means the body needs the adaptogen for that job, or that low intake is linked to it. It does not mean extra supplements help if your intake is already adequate. See each page’s evidence label.
Asian, American, Korean red, Japanese and Vietnamese ginseng and relatives: the roots that gave "adaptogen" much of its fame.
Rhodiola, eleuthero, schisandra, rhaponticum and other plants from the Soviet-era research that coined the word.
Reishi, cordyceps, chaga, lion's mane and other mushrooms sometimes called adaptogens. Their full guides are in Mushrooms.
Ashwagandha, holy basil, shatavari, bacopa and other rejuvenating tonics (rasayanas) from Ayurveda.
Astragalus, codonopsis, cistanche and other Qi and yin tonics from Chinese medicine.
Maca, suma, tongkat ali and black ginger: roots from South America and Southeast Asia.
Pine pollen, licorice, moringa, ashitaba and other plants marketed with the word adaptogen.
Adaptogens work alongside other nutrients. Here is what our sources link to them.
Vitamin A: The body can convert beta-carotene to vitamin A.
Vitamin A: Vitamin E and beta-carotene were tested together in the Finnish smoker trial.
Vitamin D: Vitamin D increases calcium absorption; both matter for bones, and treatment of rickets and osteomalacia includes both.
Vitamin D: NHS says vitamin D helps regulate calcium and phosphate.
Vitamin E: MedlinePlus says vitamin E helps the body use vitamin K; both affect blood clotting, which matters for people on blood thinners.
Vitamin E: Vitamin E and selenium were tested together and apart in the SELECT prostate cancer trial.
Vitamin E: Vitamin C and vitamin E were pooled with other antioxidants in the Cochrane mortality review.
Vitamin K: Vitamin D with K2 products exist; the site page does not claim an added benefit.
Vitamin B1 (thiamin): The NHS page covers B vitamins together; MedlinePlus says doctors may recommend other vitamins alongside thiamin for beriberi.
Vitamin B2: MedlinePlus says riboflavin works with the other B vitamins.
Vitamin B3 (niacin): Pellagra comes from too little niacin or tryptophan in the diet, so both matter for avoiding deficiency.
Vitamin B5: MedlinePlus covers pantothenic acid and biotin together; both are needed for growth and metabolism and for making fatty acids.

These adaptogens have the most human research summarized in our guides (counted from the evidence ratings on each profile). More research does not mean the adaptogen works or is safe for you: open the guide to see what was found, including negative and mixed results.
Every published adaptogen guide (12), with its names and what it is made of. Each name opens one guide that brings together identity, traditional use, research, safety, forms and sources.
Search by adaptogen, benefit, body system, goal, symptom or lab test. Each result explains why it matches and how strong the evidence is.
Filters: group, evidence, body system, body part, goal, root cause, habit, biomarker, condition
Pick a way to look, then pick a choice. Every list links to the full guide.
Pick the part that is used. Different parts are often used differently and carry different cautions. A adaptogen can appear under more than one part.
Adaptogens whose guide mentions use in a traditional system. A mention shows history, not proof that it works.
The ways each adaptogen is used, from its guide: tea, tincture, capsule, powder, extract, topical or the whole adaptogen.
Adaptogens whose guide documents a point to check for this concern. Being listed does not mean the adaptogen is unsafe for everyone. Open the guide to read the details.
The best level of evidence in each adaptogen guide for any listed benefit. A stronger label for one use says nothing about its other uses or its safety.
Adaptogens have been used for health in many cultures for centuries. A traditional use tells you what people have done, not that it works. Here every adaptogen is listed under the goals, body systems and actions its guide connects it to, and each link carries the strength of the evidence behind it.

Too little evidence to say
Each adaptogen is counted once, at the strongest level its guide documents for any use. A strong label for one use says nothing about its other uses or its safety. "Traditional use" alone is not one of these labels: where a guide only reports history, the link is rated "Too little evidence to say". Read the guide on traditional use and research evidence.
Each card shows how many adaptogens are linked to a goal and how strong the evidence is. Green means clinical trials support a benefit; grey means too little evidence. These are links the guides document, not recommendations. For the wider picture, see the Wellness Goals section.

Side-by-side guides for adaptogens that people confuse or choose between. They explain differences; they do not rank the adaptogens.
Each guide below looks at one concern, from sleep to skin, and separates adaptogens that were tested in people from adaptogens that are only traditional or lab-tested.
People have used adaptogens for health for many centuries. A traditional use tells you what people have done, not that it works. For what research found, see the Health Benefits and Scientific Evidence tabs.
Ayurveda, Traditional Chinese Medicine and other traditions each use natural remedies in their own systems. The adaptogens below are the ones whose guide mentions the tradition in its own text. That a tradition uses an adaptogen is history, not clinical evidence. Each guide says separately what trials found.

Adaptogens are active substances. Some interact with prescription medicines, some are unsafe in pregnancy or with certain conditions, and some have been linked to serious harm. This tab brings together what the individual adaptogen guides document, plus the general rules. Medicine interactions have their own tab.

Some adaptogens change how a medicine works, or add to its effect. This matters most for narrow-margin medicines such as blood thinners, antidepressants, immunosuppressants, and diabetes and blood pressure medicines. Always tell your pharmacist and clinician about every adaptogen you take. Ask before starting, stopping or combining anything.
Each line comes from an adaptogen's own guide and its cited sources. A adaptogen missing from a list is not proven free of interactions: it may simply not have been studied. Open the adaptogen's guide for the full wording.

The guides cite 130 distinct sources. These are the ones cited most often, and the main places to check any adaptogen claim yourself.
The same material can be sold as a powder, capsule, liquid or concentrated extract, and these are not interchangeable. A study of one preparation does not tell you what another does. This tab shows which forms each guide describes, and how to judge product quality.
Different parts can contain different compounds, so the part named on the label matters.
For each kind of preparation, the adaptogens whose guides describe it. The guides say which form was actually studied. Detailed preparation instructions are in Herbal Teas & Extracts, so they are not repeated here.

A whole adaptogen (fresh, dried or powdered) contains everything in the raw material, in amounts that vary. A standardized extract is made to contain a stated amount of one or more marker compounds, which makes batches more consistent but is not the same as the whole adaptogen.
An extraction ratio such as 4:1 says how much raw material was used per unit of extract. It does not by itself say how much active compound a capsule holds or whether the product works. A marker compound is something measured for quality control; it is not always the compound that causes any effect.
Amounts and duration. We do not give universal dose recommendations. Where a source reports the amount and length of use tested for a named preparation, the adaptogen's guide gives it in that context; an amount studied in one product does not carry over to another, or to food-level use.
Absorption. Some active constituents are poorly absorbed, which is why concentrated or specially formulated products exist (curcumin is the best-known case). Better absorption can also raise the risk of side effects.
A good label names the species by its scientific name, says which part is used, and states the amount and form. Third-party testing can check identity, strength and contamination, but a seal is not a guarantee of safety or benefit.
