Mangosteen is a super-food because of its rich store of essential nutrients which are beneficial to your whole body for growth, development and nutritional well being. It’s a tropical fruit with a hard red to purple outer shell, a soft inner fruit and seeds. This fruit not only maintains your optimal health but also helps you fight health problems from heart disease to asthma–and much more. If your nutrition gauge is on the low side, you will immediately notice a boost in energy levels when you take mangosteen. It is similar to other super fruits such as acai berry, noni and goji.
