Why Not Natural sells a single-ingredient ashwagandha capsule built on KSM-66, a branded root-only extract standardized to more than 5% withanolides. KSM-66 is one of the most studied ashwagandha extracts, with published trials behind it, and this formula adds no fillers or additives. It suits people who want a plain, well-standardized root extract for stress, sleep and recovery support rather than a blend with added herbs. Against rivals, the main differentiators are the root-only extract, the low withaferin A content and the third-party testing; the trade-off is a simple one-ingredient capsule with no extras like black pepper or magnesium.

This supplement contains KSM-66 Ashwagandha, a full-spectrum extract made from the root only. Ashwagandha is an adaptogenic herb that helps the body and mind adapt to stress. It also promotes better sleep, helps promote muscle strength, size and recovery, and helps memory and cognition.
KSM-66 has more than 5% withanolides and almost no Withafarin A, a withanolide that should be avoided. The extraction process retains the original balance of the plant compounds. It uses green chemistry principles, with no alcohol or synthetic solvents.
Ashwagandha has been used in Ayurveda, where it is also known as "Indian Ginseng", since at least 6000 BC. KSM-66 Ashwagandha has been evaluated in 24 published trials. The formula uses no fillers or additives and is third-party tested for purity and potency.
