Youtheory® Ahswagandha is powered by KSM-66® – an organic full-spectrum ashwagandha extract. KSM-66 is the highest potency ashwagandha on the market sourced only from the root. Ashwagandha (commonly called Indian Ginseng) is one of the most highly prized botanicals in the ancient Ayurvedic system of India. It is often described as an “adaptogen” because it helps the body successfully adapt to stressful conditions. When used regularly over time, Ashwagandha helps combat stress and provides numerous benefits for the body and brain.
