Zinc is a trace that your body only needs in small amounts, and yet it is necessary for your body in creating roughly 100 enzymes that perform vital chemical reactions. It is a major factor for creation of DNA, growth of cells, building proteins, healing of damaged tissue, and, the most popular function, supporting a healthy immune system. Symptoms of a lack of zinc can be wounds that won’t heal, weight loss, decreased sense of smell and taste, and sores on the skin. It is found in all body tissues. It is safe to take every day in doses from 10-50mg for most people, or higher doses for only a few days. Taking high dosages every day can decrease the amount of copper the body absorbs, and be a factor in hair thinning or hair loss.
