One of the most common elements in the earth's crust, zinc is found in the air, soil, and water and is present in all foods. Used since ancient Egyptian times to enhance wound healing, zinc is a mineral that is necessary for the functioning of enzymes and plays a vital role in many biological processes, including the production of cells that help keep the body healthy.

Why is zinc necessary?
Zinc helps maintain optimum immune function and boosts immunity, and creates new cells which allows healthy collagen production and wound healing. It is also a component of key enzymes that help preserve vision and protect against age-related vision loss, including macular degeneration. Zinc further plays a role in carbohydrate and protein metabolism, and may be beneficial as a supplement for people with severe diarrhea, sickle cell anemia, gastric ulcers, and acne. In addition, zinc is vital for normal fetal development and the maturation of sperm.

What are the signs of a deficiency?
Signs of zinc deficiency include hair loss, weight loss, delayed wound healing, chronic infection, and rough skin or rashes. Symptoms include poor appetite, depression and mental lethargy.

How much, and what kind, does an adult need?
Dr. Talebi recommends adults take 15 mg of zinc daily, or up to 30 mg daily for vegetarians or for those who don’t eat many foods of animal origin.
