Quick verdict: If you want ashwagandha in a gummy, choose one made with KSM-66, the most studied ashwagandha root extract. Our top pick is Goli Ashwagandha Gummies for its wide availability and simple formula. If you want the full dose used in most studies in a single serving, look at a 600 mg KSM-66 gummy instead.
What is ashwagandha?
Ashwagandha is an herb that has been used for centuries in traditional Indian medicine. Today it is one of the most popular supplements in the U.S. for managing everyday stress. KSM-66 is a branded extract made only from the root and standardized to at least 5% withanolides, the plant’s main active compounds.
What the research says
The best-known study on KSM-66 (Chandrasekhar et al., 2012) followed 64 adults with chronic stress. Those who took 300 mg twice a day (600 mg per day) for 60 days reported lower stress scores and had lower cortisol, a stress hormone, compared with placebo.
The U.S. National Institutes of Health (NIH) says ashwagandha extracts might help reduce stress and anxiety, and that sleep benefits were small and seemed strongest at 600 mg a day or more for at least 8 weeks. Most studies lasted 8 to 12 weeks, so long-term effects are not well known.
Our top pick: Goli Ashwagandha Gummies
- Ashwagandha: 300 mg KSM-66 root extract per serving (2 gummies)
- Also contains: vitamin D2 (25 mcg) and about 4 g of added sugar per serving
- Servings: 30 per bottle (60 gummies)
- Diet: vegan, gluten-free, gelatin-free, non-GMO
- Typical price: about $15–$19 per bottle
Pros: uses the KSM-66 extract; tastes like a mixed-berry candy; easy to find in U.S. stores.
Cons: one serving gives 300 mg — half the 600 mg daily dose used in most studies; contains added sugar; if you also take a vitamin D supplement, check your total.
Alternative: 600 mg KSM-66 gummies
Some gummies, such as The Vitamin Shoppe brand Ashwagandha Gummies with KSM-66, provide 600 mg of KSM-66 per 2-gummy serving — the dose used in most studies — but they usually cost more per serving.
