Zinc (as Oxide): Zinc is involved in numerous aspects of cellular metabolism. It is required for the catalytic activity of approximately 100 enzymes and it plays a role in immune function, protein synthesis, wound healing, DNA synthesis, and cell division. Zinc also supports normal growth and development during pregnancy, childhood, and adolescence and is required for proper sense of taste and smell. (National Institutes of Health)
Selenium (as Sulfate): Selenium is a mineral found in the soil and it naturally appears in the water and some foods. It has attracted attention because of its antioxidant properties. While people only need a very small amount of this, Selenium plays a key role in metabolism.

The chemicals in gelatin, called amino acids, can be absorbed in the body.
