Rhodiola

Rhodiola rosea, also called roseroot or golden root, from the stonecrop family

A root of high mountains and the far north, studied mostly for tiredness, endurance exercise and stress. Here is every study in people we could find, sorted from each study's summary.

  • Part used: root
  • Most tested: 400 mg a day
  • Often 4 weeks or less

The research map

From every paper to the studies that matter

Most research on rhodiola is in the lab or about the plant's chemistry. Only a small share tests it in people, and that is what this page is about.

  1. 1,725 papers mention rhodiola. Every record in PubMed, all years
  2. 95 are about people. The rest: 957 lab and animal studies, 156 reviews, 517 on chemistry, farming and more
  3. 59 give rhodiola on its own. 28 more test it inside a blend
  4. 33 are randomised against a placebo. The strongest kind of study

Bar lengths use a square-root scale so the small numbers stay visible.

What was measured

What the studies looked at

Each study can measure several things. Choose a topic to see its studies in the list below.

Studies in people with a diagnosed condition are counted here and listed with their population. We describe what they measured, not what they might treat. Most studies also report safety; see below.

Doses and extracts

What was tested, and how much

Rhodiola extracts are made in different ways, so the same number of milligrams can mean very different amounts of the plant's active compounds. Several studies used a named extract, most often SHR-5, and a few sports studies gave one dose before exercise.

Daily amount, one dot per study

Studies per extract

  • SHR-59
  • Golden Root Extract3
  • Other named20
  • Not named27

Named extracts are the maker's brand. "Not named" means the study didn't say.

Safety

What's known about safety

  • In trials

    A review of 11 placebo-controlled trials found only a few mild side effects. Headache, dizziness, stomach upset and poor sleep are listed, and it is thought possibly safe for up to 12 weeks.

    Hung 2011, review of 11 trials; NCCIH, updated April 2025; EMA herbal monograph, 2024

  • In the UK

    Rhodiola rosea root can be sold in food supplements. It is also in several registered traditional herbal medicines (THR), which are approved on long use rather than trial results.

    EU Novel Food Status Catalogue; FSA novel foods guidance; MHRA products register, THR 23056/0039 and 21710/0020, Oct 2026

  • Check first

    It isn't recommended in pregnancy, breastfeeding or under 18, because there isn't enough safety data. Interactions have been reported with losartan, a blood pressure medicine, and with an antidepressant, so speak to a pharmacist or doctor first if you take regular medicines.

How we built this

Where these studies come from

We list every published study of rhodiola in people. This first version is built from each study's summary; full-paper checks come next.

  1. We search

    PubMed, the world's main library of medical research, for every paper on L-theanine.

  2. We keep studies in people

    Lab and animal work is counted but left out of the list, because it doesn't tell you what happens in people.

  3. We note the basics

    Who took part, how many, how much and for how long, from each study's published summary. A second check corrects what the first read gets wrong.

  4. We read them in full

    Results appear once we've read the whole paper and checked every number. The date at the top shows when this entry was last updated.
