Cordyceps sinensis is a fungus that has been used by traditional Chinese herbalists for its energizing and adaptogenic properties for centuries. Cordyceps has numerous bioactive compounds, including polysaccharides and nucleosides, which have been studied for their broad range of biological activities. Modern scientific studies have shown that Cordyceps constituents possess free radical scavenging properties and suggest that they may also support a healthy immune system and promote normal vascular function.* NOW® Cordyceps is a 100% vegetarian product made especially for those seeking a traditional supplement for their dietary needs.
