Glucosamine Chondroitin MSM

Mangosteen is a dietary supplement that offers several classes of powerful phytonutrient antioxidants that have been derived from the mangosteen (Garcinia mangostana L.), an exotic fruit that comes from Southeast Asia. The mangosteen has been nicknamed the "Queen of Fruits" and in some parts of the world the "Food of the Gods" for its various health benefits and for its delightful taste. For thousands of years, Asian countries have been using the mangosteen in Chinese, Ayurvedic and folk medicine to support optimal health. The secret to the mangosteen's health promoting abilities is the xanthones contained in the fruit. Xanthones are biologically active plant phenols that are structurally similar to flavonoids that have been found to possess multiple health benefits. Xanthones posses an extra electron, and help to seek out and quench free radicals in the body. Excellent source for antioxidants.
