"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 1200mg of KSM-66 root extract (from a 12:1 extract) per serving of 2 tablets, once daily. Bottle contains 365 tablets; the listing states this is a 6-month supply, which is used here for the day-supply calculation rather than the raw 365 ÷ 2 = 182.5 tablet count. Vegan, non-GMO, gluten-free. Manufacturer claims post-production heavy-metals testing and BRC-certified packaging facilities; no specific lab or certificate was linked.
