Ashwagandha, an adaptogenic herb, is an important component of traditional Ayurvedic Medicine. As an adaptogen, Ashwagandha extract has wide-ranging health benefits, most notably in combating the negative effects of stress and supporting a healthy immune system. Some recent studies have also indicated potential benefits for healthy mood and cognitive function. The key constituents of the herb (what makes it useful as a health supplement) include withanolides, alkaloids, choline, fatty acids and amino acids. Our Swanson Superior Herbs line of standardized herbs features an Ashwagandha Extract that is standardized to 1.5% withanolides for guaranteed potency.
