What Is Zinc?
**Zinc** is a mineral that is crucial for maintaining overall health. It is involved in over 300 enzymatic reactions in the body, supporting functions such as metabolism, immune response, protein synthesis, and DNA synthesis. Unlike some minerals, Zinc cannot be stored in the body in significant amounts, so a regular intake through diet or supplementation is necessary to maintain optimal levels.
Zinc is found in various foods, particularly in animal-based products, but deficiencies can occur, especially in individuals with certain dietary restrictions or health conditions. Supplementation can help bridge the gap, ensuring that the body receives adequate Zinc to perform its essential functions.
