KSM-66 Ashwagandha Supplement

• CLINICALLY-STUDIED & AWARD WINNING KSM-66 ASHWAGANDHA: Double Wood’s Ashwagandha is formulated with KSM-66 which is backed by 20 years of research. This full spectrum extract is supported by extensive research, 32 published “Gold Standard' clinical trials and 42 high quality certifications. Because when you're rooted in science, wellness grows.
• STANDARDIZED TO 5% WITHANOLIDES — ROOT-ONLY EXTRACT: KSM-66 Ashwagandha is standardized to 5% withanolides, the bioactive compounds responsible for ashwagandha's adaptogenic, cortisol-modulating, and performance-enhancing effects. KSM-66 is extracted exclusively from the root of the Withania somnifera plant — not from leaves or stems — which produces a cleaner, more consistent withanolide profile and is the reason KSM-66 is backed by 24+ human clinical trials, more than any other ashwagandha extract on the market.
• KSM-66 ASHWAGANDHA BENEFITS: KSM-66 Ashwagandha offers several well-studied benefits, including supporting healthy cortisol levels, mental clarity, and a more positive mood. It also supports physical performance by boosting strength, endurance, and muscle recovery, while promoting overall well-being and vitality.
• ROOTED IN QUALITY: Manufactured and Tested in the USA from Globally Sourced Ingredients. Double Wood's KSM-66 Ashwagandha is sourced from the only ashwagandha manufacturer in the world with it’s own farms, production facilities, research and testing centers so you get purity and potency with every dose
• WE BOTTLE WELLNESS: At Double Wood we provide pure, potent supplements that deliver exceptional value, all backed by careful sourcing and rigorous third-party testing

Take 2 capsules per day, with or without food. KSM-66 can be taken in the morning to support daytime stress resilience and cognitive function, or in the evening to support sleep quality and overnight cortisol regulation — both are studied. Most users report noticeable effects within 4–8 weeks of daily use; clinical trials showing cortisol reduction used 8–12 week supplementation windows. Some users cycle ashwagandha (8 weeks on, 2–4 weeks off), though no specific cycling requirement has been established in the literature.
