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.
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, ConsumerLab.com'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.
