Zinc, Plasma

What This Marker Means

Zinc supports immunity, wound healing, hormone balance, and neurological function. Low levels may cause low appetite, poor mood, slow recovery, or increased illness. Plasma zinc reflects short-term status.

How Alcohol Affects This Marker

Alcohol increases urinary zinc loss and reduces intestinal absorption. Low zinc is extremely common in people who drink frequently and contributes to cravings, poor immunity, and slow healing.

How to Discuss With Your Doctor

If low, ask whether supplementation or dietary adjustments are appropriate. Mention drinking habits so your doctor can identify zinc depletion as a contributing factor.
