More about this report

It's very hard to find a good ashwagandha supplement. Only 25% of the products we selected to review passed our tests and quality criteria. Meanwhile, there is increasing evidence that ashwagandha may reduce anxiety, improve memory, and have other beneficial effects.

Many ashwagandha supplements don't deliver their labeled amounts (or a reasonable dose) of expected ashwagandha compounds, called withanolides. At a minimum, an ashwagandha product should provide 6 mg of these per day, yet 3 products contained less -- one didn't even provide 1 mg! Two contained much more withanolides than listed.

Fortunately,'s tests found 3 ashwagandha supplements of high ingredient quality with accurate labeling and dosages like those used in successful clinical trials -- including trials for treating anxiety.

You must be a member to get the full test results and quality ratings for ashwagandha supplements and ConsumerLab's recommendations. In this comprehensive report, you'll discover:
    • Which ashwagandha supplements failed testing, which passed and, of these, which one is the best value  
    • The amount of withanolides in each ashwagandha supplement and how much to look for 
    • How ashwagandha root powders and root extracts differ, and what they have been shown to do    
    • Ashwagandha dosage for specific uses, such as reducing anxiety and improving memory  
    • Potential side effects and drug interactions with ashwagandha

(1/23/15): was contacted by a representative of the distributor of one of the products which failed to pass this review for not meeting expectations applied by CL. CL acknowledges that it mistook the product for being a concentrated extract when information on its label indicated it to be a more dilute extract. CL has corrected the information in the report about this product, indicating that it does meet the expectations of its label, although it still does not pass the review as it does not provide the minimum expected total daily amount of withanolides generally shown to be effective in clincal trials. CL recognizes that it made a similar error with regard to a second extract and has corrected this information as well. That product also continues to not meet expectations applied by CL, as it provides a lower dose than expected from its label and a low daily dose.

(12/23/14): was contacted by the distributor of one of the products which failed to pass this review. The distributor claims that the product should not have been held to the expectations applied by CL. However, CL believes that it properly interpreted the product labeling and applied appropriate expectations. More details are available in the Update in the full review.
