"Resemblance to studied formulations" describes how closely this product's extract, form and dose match preparations used in published research - it is not a claim that the product itself has been clinically tested, and it does not mean the product "works" for any individual.

Ingredients & suitability

Vegan Vegetarian

Manufacturer states each tablet provides 150mg of KSM-66 ashwagandha root extract (10:1 ratio), described on the label as equivalent to 1500mg of ashwagandha powder, standardised to 5% withanolides. Labelled vegan, vegetarian and non-GMO. 180 tablets, 1 tablet daily (label states a 6-month supply, consistent with this rate). No third-party testing claim was found on the listing.
