Ashwagandha

Ashwagandha is an evergreen shrub native to India and North America. Its roots and leaves are used to make medicine and dietary supplements. The plant is typically grown for its medicinal properties.

Ashwagandha is most often found in beverages like water, soda, and sports drinks, as well as in supplements. Manufacturers add it for its adaptogenic properties, which are believed to help the body manage stress. It is not typically used as a functional ingredient like a sweetener or preservative.

Ashwagandha is generally available as a dietary supplement in the U.S. The FDA does not regulate supplements in the same way as drugs or food additives. Some research suggests ashwagandha may help reduce stress and anxiety, and improve sleep. However, more high-quality studies are needed to confirm these effects. JECFA has evaluated ashwagandha and has not set a numeric acceptable daily intake (ADI). Evidence regarding its long-term effects and safety at high doses is still being studied.
