All Potential Benefits Studied

Includes emerging, secondary, and context-dependent effects

1

Increases Testosterone Levels 1 2 3 4

Zinc supplementation can significantly increase testosterone levels, but only when a deficiency is present. Studies have shown meaningful increases in testosterone in zinc-deficient individuals, but supplementation has little effect in those with normal zinc levels.

2

Boosts Immune Function and Reduces Infection Risk 5 6 7 8

Zinc is essential for immune system function, and deficiency increases susceptibility to infections. Maintaining adequate zinc levels supports immune health, and supplementation may help prevent pneumonia in children.

3

Shortens Cold Duration 9 10

Zinc lozenges can reduce the duration of colds by limiting viral replication in the nasal epithelium. However, they must be taken at high doses and early in the infection. Nasal sprays may also be effective, though they carry a higher risk of side effects.

4

Improves Depressive Symptoms 11 12

Zinc supplementation has been linked to improvements in depressive symptoms, particularly in individuals with chronic conditions.

5

Supports Glycemic Control and Heart Health 13 14

Zinc may help regulate blood sugar levels and improve blood lipid markers, especially in people with metabolic disorders.

6

May Help with Severe Acne 15 16

Zinc supplementation has shown promise in improving severe acne, though more high-quality studies are needed to confirm its effectiveness.
