Zinc and Sexual Health: What It Does and When It Helps
Updated 2026-11-01 · Draft: awaiting expert review
Correcting a zinc deficiency is linked to healthier hormone levels. There is little evidence that extra zinc helps people who already get enough.
Zinc plays a role in hormone production and fertility. Here is what the research says, which foods are rich in it, and why more is not better.
Why zinc matters
Zinc is a mineral your body uses for hundreds of processes, including immune function, wound healing, and the production of hormones. In men, zinc deficiency is associated with low testosterone and reduced sperm production.
Because the body does not store zinc well, you need a steady supply from food.
How much do adults need?
- Recommended daily amount: about 11 mg for adult men and 8 mg for adult women (higher during pregnancy and breastfeeding).
- Upper limit for adults: 40 mg per day from all sources, including supplements.
Good food sources
- Oysters (by far the richest source), other shellfish
- Red meat and poultry
- Beans, chickpeas, lentils
- Nuts and seeds such as pumpkin seeds and cashews
- Whole grains and dairy
Do supplements help?
If you are deficient, correcting it can make a real difference. If you are not, there is no good evidence that extra zinc boosts libido or performance.
Taking too much zinc for a long time can cause copper deficiency and weaken immunity. Talk to a doctor before taking high-dose supplements, especially if you take other medications.
