If you take GLP-1 medicine, zinc is one nutrient worth checking in your glp1 multivitamin. Zinc supports immune cells, wound healing, and the lining of the gut. Research on zinc specifically for people on GLP-1 medicine is still limited, so this guide separates what is known from what is not.
What Zinc Does in Your Body
Zinc takes part in many body processes. It helps immune cells work, supports wound healing, and is needed for normal cell growth. Your body cannot store zinc for long, so you need a steady supply from food or supplements.
Good food sources include meat, shellfish, beans, dairy, and seeds such as pumpkin seeds.
Why Zinc May Run Low on GLP-1 Medicine
GLP-1 medicines often reduce how much people eat. Eating less means less zinc from food, especially if you cut back on meat, dairy, or beans.
A 2026 review of six studies named vitamin D, iron, and B vitamins as nutrients people on these medicines were particularly prone to lacking. Zinc was not one of them. That means the evidence for zinc on GLP-1 medicine is thinner than for the other three.
Immune Function: Why Zinc Matters
Zinc is needed for immune cells to develop and respond. A review of zinc and immunity describes this role in detail.
Zinc is not a shield against illness, though. More is not better. Taking large amounts of zinc over a long time can lower copper levels, which can cause its own problems. Ask your doctor how much zinc fits your needs.
Gut Repair: What the Research Shows
Zinc helps keep the intestinal lining, called the mucosal barrier, working well. A review on zinc and the gut barrier reported that both zinc shortage and zinc excess can weaken this barrier.
Most of that evidence comes from lab and animal studies. The authors said that whether zinc can treat gut diseases still needs clinical testing. No study so far proves that zinc supplements repair the gut in people on GLP-1 medicine.
Hair Shedding: A Small Link
Zinc is sometimes linked to hair shedding. In a 2025 study of 2,279 patients with hair loss, zinc levels were slightly lower than in the comparison group. The authors called the difference minor and not clinically significant. They also said routine zinc testing is not recommended for hair loss.

Frequently Asked Questions
Should I take zinc every day?
Ask your doctor first. Zinc needs vary by age and sex, and long-term high doses can lower copper.
