Cordyceps is a genus of parasitic fungi originating from the Asian highlands and containing valuable active compounds such as cordycepin, adenosine, and polysaccharides. Thanks to its antioxidant and anti-inflammatory effects and ability to increase ATP, this medicinal ingredient supports endurance, blood sugar regulation, cardiovascular protection, and slowing the aging process. In particular, cordycepin is notable for its potential to inhibit cancer cells and effectively improve immune function.
