Zinc is one of the more evidence-backed minerals in male vitality formulas, with a direct, well-studied link to testosterone production.
The Deficiency Link
Studies inducing mild zinc deficiency in healthy men have shown measurable drops in testosterone, with levels recovering after zinc repletion.
Who's at Risk of Low Zinc
Diets low in meat and shellfish, high alcohol intake, and certain digestive conditions are all associated with lower zinc status.
Beyond Testosterone
Zinc also plays a central role in immune function, wound healing, and taste perception — making it one of the more broadly useful minerals in a daily formula.
