What is Rhodiola?

From the FDA label:An adaptogenic herb taken for stress resilience and fatigue.

What the evidence says

What Rhodiola is

Rhodiola (Rhodiola rosea) — also called arctic root, golden root, rose root, rosenroot, or king's crown — is a plant that grows in cold regions and at high altitudes in Europe, Asia, and North America. Its root has a history of traditional use (for purposes such as work performance, endurance, fatigue, and altitude sickness), and extracts are sold today as dietary supplements.

Commonly used for

Athletic performance and physical enduranceFatigue and energyStress reductionMoodCognition (mental performance)

What the evidence shows

According to NCCIH, there isn't enough reliable evidence to determine whether rhodiola or its components are useful for any health-related purpose. Most of the research in people is of low-to-moderate quality, and NCCIH states it hasn't learned enough to say whether rhodiola is useful for any health-related purpose. The uses above reflect what rhodiola is traditionally used for or promoted for, not benefits that have been established.

Typical dosage

There is no established standard dose; NCCIH does not specify a recommended amount. Safety data extend only to about 12 weeks of use (see Safety). Because the evidence is limited and product strength varies between brands, talk to your doctor or pharmacist before starting rhodiola — especially if you take medication, are pregnant or breastfeeding, or have a health condition.

Safety

NCCIH describes rhodiola as possibly safe when used for up to 12 weeks; its safety beyond that period has not been established. Little is known about whether rhodiola is safe to use during pregnancy or while breastfeeding.

Side effects

According to NCCIH, possible side effects include dizziness, headache, and trouble sleeping, along with either a dry mouth or, conversely, excess saliva.

Interactions & cautions

NCCIH notes that rhodiola has been reported to interact with losartan, a blood-pressure medication. Let your healthcare provider know about every supplement you take so they can check for possible interactions with your medicines.

What people report to the FDA about Rhodiola Rosea

The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 96 reports naming Rhodiola Rosea — the active ingredient in Rhodiola, and the FDA flagged 75% of those reports as serious. The effects reported most often — leaving out reports about overdose, misuse or the condition being treated, which dominate the raw list for common medicines:

  • feeling abnormal10 reports
  • diarrhoea8 reports
  • disturbance in attention8 reports
  • fatigue8 reports
  • nausea8 reports
  • dizziness7 reports
  • neuropathy peripheral7 reports
  • suicidal ideation7 reports

Read these as a signal, not a rate. A report does not mean Rhodiola Rosea caused the effect — anyone can file one, and many describe people taking several medicines for several conditions. Crucially there is no denominator: FAERS does not record how many people took the drug, so these counts cannot be turned into “X% of patients” — a bigger number often just means a more widely used or more talked-about drug. Duplicates exist, and publicity drives reporting. For what is actually established, read the FDA label.
