Siberian Ginseng is a superior tonic herb shown to be effective for athletes and active people for supporting their levels of energy stamina and endurance. Because Siberian Ginseng roots are too hard to assimilate we process our roots into a liquid extract which is dried into a concentrated powdered extract. It takes 10 pounds of pure roots to make one pound of our 10:1 concentrated extract powder which is much more easily absorbed for better nutritional support.Other products from HerbsPro
