Healthy Vascular Function**
Cordyceps sinensis is a species of fungus that has been widely used by traditional Chinese herbalists for its rejuvenative and adaptogenic properties for hundreds of years. Recent scientific research on Cordyceps has uncovered a broad range of biological actions, which are conferred primarily through its high polysaccharide content. Cordyceps sinensis has been found to exhibit antioxidant properties, and support a healthy immune system, as well as to promote healthy vascular function.** NOW® Cordyceps is a 100% vegetarian product made especially for those seeking a traditional supplement for their dietary needs.
