There are many minerals required for human health, including calcium phosphorus, iodine, iron, magnesium, zinc and selenium.  While minerals have long been found in supplements and fortified foods, they are increasingly appearing in new products, from functional foods to cosmetics. 

 

For nutraceutical use in functional foods and beverages, popular mineral additives include potassium, magnesium, calcium, selenium and zinc.  Each of these minerals supports key functions in the body when at an appropriate level.  Magnesium, for example, promotes bone health and supports energy and healthy blood sugar levels, while selenium is critical to the work of antioxidant enzymes.

 

In personal care and cosmetics, minerals enjoy widespread use. Copper detoxifies the skin and promotes collagen production, calcium maintains skin thickness and promotes cellular regeneration, magnesium soothes the skin and potassium helps maintain hydration.  Skin care products generally combine minerals, often derived from mineral-rich natural sources like sea salts and clay.
