Ashwagandha

Ashwagandha is a Botanical supplement available in 1 form.

Not all forms of Ashwagandha are equal. The form you choose determines how much Ashwagandha actually reaches your tissues, and the difference between the best and worst forms can be substantial. Root extract forms (KSM-66, Sensoril) deliver concentrated withanolides at standardized potency, providing up to 87x greater active compound delivery compared to raw root powder. Clinical trials consistently use standardized extracts, not whole root, for reproducible outcomes.

Ashwagandha (Withania somnifera) Root Extract Preferred (Preferred Form) has a bioavailability rating of good (S2). Typical dose range: not yet documented in our database.

Ashwagandha root extract (Withania somnifera) has been studied extensively for its adaptogenic properties. KSM-66 and Sensoril are the most clinically studied standardized extracts, with multiple randomized controlled trials demonstrating support for stress resilience, sleep quality, and exercise performance. Root extract forms are preferred over whole-plant preparations due to higher withanolide concentration and more consistent clinical outcomes.

Shoden ashwagandha (35% withanolide glycosides) achieved 226-281x greater systemic withanolide exposure per gram vs standard root powder PMID: 40792075

KSM-66 root extract (5% withanolides) demonstrates mid-range pharmacokinetic profile between root powder and high-concentration extracts PMID: 38144272

Withanolide glycoside standardization directly correlates with plasma withanolide exposure in dose-response study PMID: 38122911

Ashwagandha (Withania somnifera) Root Extract is classified as Preferred Form by FormulaForge — our top recommendation for Ashwagandha. It carries a bioavailability rating of good (S2), meaning more of the active compound reaches your tissues per dose unit compared to lower-rated forms.

When choosing a Ashwagandha supplement, look for the S1 (best absorption) bioavailability tier on the label. Preferred Forms have the strongest research-backed evidence for efficient absorption.

Other forms may be appropriate depending on individual goals, cost considerations, and your healthcare provider’s guidance. The best form for you depends on your specific health needs.
