The Active Ingredient Is: Zinc (Sulfate Form)

Zinc is a mineral that acts as a cofactor in numerous enzymatic reactions and plays a pivotal role in normal immune, cellular, and skin function.

This formulation provides zinc primarily from zinc sulfate and is presented as a hypoallergenic option suitable for sensitive individuals, with a clear label of the active ingredient zinc.

What Does Zinc Do?

Zinc supports immune cell development and function, DNA synthesis and protein formation, wound healing and antioxidant defence, and helps maintain healthy skin and mucosal barriers. It also supports the production and activation of T lymphocytes, helping regulate inflammation.

Evidence from independent research supports these roles, with findings noting zinc can influence immune response in adults. This aligns with EFSA/ NHS interpretations of zinc as a nutrient essential for normal immune and skin functions.
