Our take on the NOW Foods Ashwagandha KSM-66 300 mg Veg Capsules

NOW Foods Ashwagandha uses KSM-66, a full-spectrum root extract standardized to 5% withanolides, at 300 mg per capsule. KSM-66 is one of the most studied ashwagandha extracts, linked to stress and sleep support in several small trials. The capsules are vegan and vegetarian, and NOW is a large, widely stocked supplement brand, so this sits among the better-documented budget ashwagandha options. It suits adults who want a single-ingredient, clearly standardized capsule rather than a blend.

Questions and answers

How does KSM-66 differ from plain ashwagandha powder?
KSM-66 is a root-only extract standardized to 5% withanolides, so each capsule delivers a consistent dose. Plain root powder is unstandardized and varies batch to batch.
How many capsules should I take?
The label dose is one capsule, but many studies use 300 to 600 mg of KSM-66 daily. Follow the label or your doctor's advice rather than guessing.
When should I take it?
Many users take it in the evening because it can make some people drowsy. If it keeps you awake, try taking it in the morning instead.
Is it vegan?
Yes. The capsules are vegetarian and vegan, and the formula contains no animal-derived ingredients.
Can I take it with other supplements or medication?
Ashwagandha can interact with thyroid medication, sedatives and blood pressure drugs. Check with a doctor or pharmacist before combining it with prescriptions.
How long until I notice a difference?
Most users who report benefits notice them after two to four weeks of consistent daily use. Give it several weeks before judging.
