2/10 Legitimate
High confidence

Hype Score

0 = legit, 10 = all hype

"It's a single-ingredient ashwagandha tablet using the patented KSM-66 root extract, a well-standardised form with genuine clinical backing for stress and sleep support."

Similar to Solgar Ashwagandha, Holland & Barrett KSM-66, or any 300–600mg standardised ashwagandha capsule
Real benefit May modestly reduce perceived stress, lower cortisol, and improve sleep quality after 8–12 weeks of daily use.
The catch The 1500mg dose is 2–5x higher than what clinical trials actually used, so you're likely paying for more powder than you need — a cheaper 300–600mg product would probably deliver the same results.

Bottom line: A well-priced, transparently dosed ashwagandha supplement using a clinically studied extract form — one of the more honest products in the supplement space.

Consumer advice

  • This is a reasonable buy if you're looking for ashwagandha for stress or sleep support. The KSM-66 form is legitimate and the price is fair. However:.
  • check the label for withanolide % to confirm standardisation;.
  • if you take thyroid medication, sedatives, or immunosuppressants, consult your doctor first;.
  • the 1500mg dose is higher than what's been studied — you could likely get the same effect from a 300–600mg product at lower cost per tablet.
