Minerals are nutrition rich food supplements that help in maintaining good health. Minerals such as calcium, chromium, Iron, zinc, folic acid and iodine protect bones, maintain hormone insulin and boost human energy levels. Minerals can only be taken from external sources and cannot be generated by our body. Minerals are classified in two broad categories: “macrominerals” such as calcium and magnesium (these minerals are generally needed in larger quantity for human body), and “trace minerals” such as iron, zinc selenium and folic acid (these minerals are needed in small quantity).
