The human body needs to absorb about 10 mg zinc and 300 mg magnesium every day, and, in particular situations, such as when we are stressed or engaged in physical activity, it may need more. As a cell-protecting antioxidant, zinc can prevent infections and allergies. It has an antiviral effect, thereby improving the mucosal structure so that viruses cannot so easily penetrate it or attach themselves to it. Its anti-inflammatory properties help wounds to heal. Zinc is found in, for example, hair, bones, skin, eyes and the liver. It is involved in many processes in the human body, both as a constituent and stimulus of numerous enzymes. And, as the human body itself is unable to produce zinc, and retains only a limited amount, a continuous supply from food is essential. Zinc also promotes the growth of skin, hair and nails.
