Strom Sports Ashwagandha KSM-66® — 500mg Per Capsule | 120 Capsules | 60–120 Servings

Strom Sports Ashwagandha KSM-66® delivers 500mg of the world's most clinically studied Ashwagandha extract in every capsule — standardised to 5% Withanolides (25mg per serving) for consistent, reliable potency. Originally featured as a key ingredient in Strom's SupportMax Neuro formula, the overwhelmingly positive response led to this standalone product, giving you the flexibility to dose it on your own terms.

KSM-66® is the gold standard of Ashwagandha supplementation. Unlike generic or full-spectrum extracts that use solvents in their extraction process, KSM-66® is produced using an exclusively root-based extraction — preserving the natural balance of the plant's bioactive compounds as nature intended. It is the most extensively researched Ashwagandha extract on the market, backed by over 22 clinical trials demonstrating measurable benefits across stress, cortisol, testosterone, cognitive function, sleep quality and physical performance.

With 120 capsules per tub, you have between 60 and 120 servings depending on your preferred dose — making this one of the most cost-effective Ashwagandha supplements available. Use it solo, or stack it seamlessly alongside your existing supplements for added adaptogenic support.

Suitable for Vegetarians. Not suitable for Vegans. Produced in a facility that handles milk, soy, egg and gluten.

Key Benefits

How To Use

  1. Take 1–2 capsules daily with water.
  2. For stress management and cognitive support: take in the morning, at least 2 hours after waking to avoid interference with the body's natural cortisol rhythm.
  3. For sleep and recovery support: take in the early evening with food to allow the calming effect to build before bed.
  4. For both: split the dose — 1 capsule in the morning and 1 capsule in the evening.
  5. Do not exceed 2 capsules daily. Consult a healthcare professional before use if you are taking any medication, managing a thyroid condition, or have any autoimmune concerns. Not suitable for those under 18, pregnant or breastfeeding.
