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.
