  • Our take on the Jarrow Formulas Ashwagandha KSM-66 300 mg Capsules

    Jarrow Formulas Ashwagandha uses KSM-66, a full-spectrum root extract that is the most clinically studied ashwagandha ingredient. Each capsule delivers 300 mg, a moderate dose that sits below the 600 mg many stress studies use, so some shoppers take two capsules. It is vegan, Non-GMO Project Verified and gluten-free, which puts it ahead of many cheaper root powders on testing and label transparency. Reviewers typically report calmer mood and easier sleep after several weeks, while a minority notice little effect or mild drowsiness.

    Questions and answers

    How does KSM-66 differ from plain ashwagandha root powder?
    KSM-66 is a standardized root-only extract with consistent withanolide content and published clinical trials behind it. Plain root powders vary batch to batch and often include leaf material.
    How long until I notice effects?
    Most stress and sleep trials run 8 weeks, and owners commonly report changes after 2 to 4 weeks of daily use. Give it several weeks before judging.
    Can I take more than one capsule?
    Yes. At 300 mg per capsule, two capsules give the 600 mg dose used in many studies. Check with a doctor before going higher.
    Is it safe with thyroid medication or during pregnancy?
    Ashwagandha can affect thyroid hormones and is generally not recommended during pregnancy or breastfeeding. Talk to your doctor first if you take thyroid or sedative medication.
    Does it contain gluten or animal ingredients?
    No. The capsules are vegan, gluten-free and Non-GMO Project Verified.
