— Reviews the Evidence and Tests the Quality of Popular R. Rosea Supplements —
White Plains, New York, March 22, 2016 — Rhodiola (R. rosea) supplements are promoted to treat depression, anxiety, and fatigue — but do they really work? And do products on the market contain the right species, amounts, and appropriate doses of R. rosea? Adulteration is a known issue with R. rosea supplements. recently reviewed the clinical evidence and purchased nine R. rosea supplements in the U.S., testing them to see whether they contained their expected amounts of rosavins and salidroside - key marker compounds which may also play a role in the herb's activity. Products made from herb powders were additionally tested to be sure they did not exceed contamination limits for lead, cadmium, and arsenic.'s tests revealed that that one product contained just one-tenth of the amount of rosavin compounds expected and another contained only half. Among the products which passed testing (including four products tested through CL's voluntary Quality Certification Program), ConsumerLab identified two as its "Top Picks," as they contained the expected amounts of R. rosea compounds in doses most closely resembling what has been shown to be effective in clinical studies and at lowest cost to the consumer.

The test results and product ratings are now available in's Rhodiola Rosea Supplements Review at The report summarizes the clinical evidence regarding the use of R. rosea, dosage, what to look for on labels, safety and potential drug interactions.
