Zinc is a mineral that is essential for human health. It plays a role in various biological processes, including growth and development, the immune system, and DNA synthesis. Zinc supplements are available in various forms, such as tablets, capsules, and lozenges, and can be taken to increase zinc intake in individuals who may not get enough from their diet or who have a medical condition that affects their ability to absorb zinc from food. It is important to talk to a healthcare professional before starting a zinc supplement, as excessive intake can cause adverse effects.
How much zinc do most people need?
The daily recommended intake of zinc varies based on age, gender, and life stage. According to the National Institutes of Health (NIH), the recommended daily allowances (RDAs) for zinc are as follows:
- Adult men: 11 milligrams (mg)
- Adult women: 8 mg
- Pregnant women: 11 mg
- Breastfeeding women: 12 mg
It’s important to note that these values are general recommendations and individual needs may vary. Consultation with a healthcare professional is recommended to determine the appropriate amount of zinc for you.
What foods contain zinc?
Zinc can be found in a variety of foods, including:

It’s important to have a balanced and varied diet to ensure an adequate intake of zinc and other essential nutrients. If you have concerns about your zinc intake, consider speaking with a healthcare professional or a registered dietitian.
Who requires zinc supplements?
Anyone can be susceptible to a zinc deficiency, but certain groups of people are at higher risk, including:
- Vegetarians and vegans who don’t consume animal products, as zinc is more readily absorbed from animal sources
- Older adults, as ability to absorb zinc, decreases with age
- Pregnant and breastfeeding women, needs may not be enough through diet alone
- People with conditions that affect the absorption of nutrients from food, such as Crohn’s disease or celiac disease
- Alcoholics, as heavy alcohol consumption can interfere with zinc absorption and increase the risk of deficiency
