KSM-66® Ashwagandha Extract 500mg - 90 Capsules - 90 Day Supply

KSM-66® is a premium branded Ashwagandha extract made from Withania somnifera root. It is one of the most extensively researched Ashwagandha extracts available and has been used in numerous human clinical studies investigating areas such as stress, sleep, cognitive and physical performance, recovery, and general wellbeing.

Unlike generic Ashwagandha powder, KSM-66® provides a standardized and clearly defined extract.

Yes. KSM-66® is produced exclusively from the root of the Ashwagandha plant. No leaves are used.

This is an important difference compared with extracts that combine roots and leaves to achieve their desired active compound concentration.

Each capsule provides 500 mg of genuine KSM-66® Ashwagandha Root Extract. With one capsule per daily serving, every pouch provides 90 daily servings.

Withanolides are naturally occurring compounds found in Ashwagandha and are commonly used as a marker of extract standardization. Our KSM-66® extract is standardized to 5.22% withanolides. At 500 mg per capsule, this corresponds to approximately 26.1 mg of withanolides per daily serving.

Clear standardization means you know exactly what you're getting — instead of relying on a large Ashwagandha number on the front of the package.

Regular Ashwagandha supplements can contain basic root powder or generic extracts with varying active compound concentrations. KSM-66® stands out because it combines: 100% root-only extraction, no leaves, standardized withanolide content, extensive clinical research, consistent branded raw material, strong global recognition.

This makes it particularly suitable for customers looking for a premium, standardized alternative to ordinary Ashwagandha supplements.

Ashwagandha is an adaptogenic botanical traditionally used in Ayurveda and is now widely included in supplements focused on stress resilience, relaxation, mental wellbeing, vitality, physical performance, recovery, and sleep. KSM-66® has become particularly popular because the branded extract itself has been extensively investigated in human clinical research.

Each pouch contains 90 capsules. At the recommended serving of one capsule per day, one resealable pouch provides a complete 90-day (3-month) supply.

Yes. Quality and transparency are core principles at BULKvitamins. We use genuine standardized KSM-66® Ashwagandha and apply quality control to ensure the finished product meets its specifications.

No mystery extracts. No vague standardization.

Just 500 mg KSM-66® with 5.22% withanolides per capsule.

Take one capsule daily with water, preferably alongside a meal. Ashwagandha can be incorporated into either a morning or evening supplementation routine depending on personal preference. Consistent daily use is generally more important than a specific time of day.
