Target Endurance Formula [Vital Nutrition, Structural] is a caffeine-free nutritional supplement to support the physiological needs of body during strenuous activity. Organic target minerals are chelated to specific amino acids, making them more readily absorbed by the body. In this formula, copper, potassium and zinc are chelated to the amino acids arginine, leucine and glycine, all of which are required to produce energy in the cells. Copper and zinc are balanced for optimal use in the body. Potassium is important in the transmission of nerve impulses, muscle contractions and blood pressure regulation. Zinc is stored in rather large amounts in the bones and muscles as well as the prostate and retina. It appears to be easily depleted and is important for many enzyme functions. The target minerals have been combined with a unique blend of bee pollen, Siberian ginseng root, gotu kola herb, capsicum fruit, licorice root, glutamine and choline bitartrate.
