Factors That Affect Zinc Needs

Absorption enhancers/inhibitors

Phytates (in whole grains, legumes) reduce absorption. Animal protein improves it. Vegetarians may need up to 50% more zinc.

Tolerable Upper Intake Level (UL)

The maximum daily intake unlikely to cause harm. For adults: 40 mg. Consistently exceeding UL may cause copper deficiency or other issues.
