Intranasal zinc and zinc capsules are other forms used for supplementation. Food origins of zinc can help achieve adequate zinc levels, and supplemental forms of zinc may be necessary in some cases.

3. Meat and Poultry

Animal products, such as meat and chicken, are zinc-rich dietary powerhouses. According to the USDA, lean meats such as 90% lean beef and skinless chicken breasts are the healthiest cuts for maximum benefits.

Vegans and vegetarians may turn to legumes to add zinc to their diets due to their naturally high amounts of the mineral, and using zinc supplements can also be beneficial.

6. Nuts and Seeds

Pumpkin seeds and pine nuts provide the highest amounts of ZN, with other nuts and seeds also containing the mineral. According to the USDA, three teaspoons (30 grams) of hemp seeds provide 27% of the Daily Value (DV) for males and 37.1% of the DV for women. Cashews are also a great source of zinc as a one-ounce (28.35-gram) serving provides 14.9% of the DV for men and 20.5% of the DV for women.

7. Whole grains

Whole grains are an excellent way to get dietary zinc. Many whole grains contain a range of vitamins, minerals, and fiber and can provide 1-2.95 milligrams of zinc per cup.

8. Milk and dairy foods

According to the USDA, 1 cup of nonfat or low-fat milk includes 1.1 milligrams and 1.05 mg of zinc, respectively.
