WHY CHOOSE KSM 66 ASHWAGANDHA? – Unlike ordinary powders, KSM66 Ashwagandha is a certified organic ashwagandha root extract, which is standardised to 5% withanolides (the key active compound) for optimal potency. Each dose is powerful, consistent, and reliable. We’ve also added organic black pepper, proven to enhance ashwagandha absorption for greater effect – naturally.

GOODBYE BURNOUT, HELLO BALANCE – Ashwagandha (also known as Indian ginseng) helps your body manage stress by supporting a natural cortisol cleanse, rebalancing this so-called "stress hormone". It helps you cope with the stresses and challenges of daily life, promotes deep, restorative sleep so you wake up energised, and lifts your mood. The result? No more crashing - just calm, steady energy.
A 3 MONTH MEGA PACK – This pack of 90 ultra-concentrated capsules gives you a full 3-month supply. Just one single capsule a day delivers the equivalent of 5500 mg of organic Ashwagandha root powder, thanks to KSM-66, the patented extract that’s 10x more concentrated. This trusted natural remedy, used for millennia to reduce stress, lift the mood, and restore deep, restful sleep, is a natural cortisol blocker.
