You may have heard about zinc for immune support, but it's also key to many other bodily processes, so it's best taken daily. Here, we'll discuss zinc's health benefits and outline how much you actually need.

Key Takeaways

01.
Zinc is an essential element that contributes to enzyme function, immune health, DNA synthesis, and more.
02.
How much zinc per day you need depends on factors such as gender, diet, and overall lifestyle.
03.
Eating the right foods or consistently taking supplements will get you the zinc allotment your body needs.

Understanding Zinc and Its Benefits

Zinc is a trace element found in most cells throughout the body. While being a trace element means it exists and is needed in small quantities, zinc plays an outsized role in hundreds of bodily processes. Zinc is not simply associated with additional health benefits; it's required for the optimal functioning of these physiological processes. ^{1, 2}

How Much Zinc Should I Take? Recommended Daily Intake of Zinc

Your body does not produce or store zinc; you must replenish it regularly from food or supplements.

Recommended daily zinc dosages vary based on age, gender, and lifestyle. The Institute of Medicine recommends 11 mg per day for adult males and 8 mg per day for adult females. Most adults aged 20 and over do not consume enough zinc, with the average adult consuming about 9.9 mg of zinc a day. These are general guidelines, however. How many mg of zinc your unique body requires may change based on your diet, activity level, and other lifestyle or environmental factors.

Can you take too much zinc?

The Office of Dietary Supplements lists the daily upper limit for adults as 40 mg, noting that upper limits do not apply to people who take supplemental zinc for medical reasons with the direction and supervision of a doctor.² Excessive zinc intake can interfere with the absorption of other minerals and affect normal body functions.

Consult with a healthcare provider to understand the best dose for you.

Factors affecting zinc needs

Factors that may affect particular zinc needs include:

Some dietary choices: Because meat is a good source of zinc, vegans and vegetarians may find it a little harder to meet daily zinc needs through diet alone.
Highly active lifestyles: You may need more zinc than usual if you engage in high-intensity exercise, which can increase mineral demands.³

In all of these situations, you may benefit from zinc supplementation to ensure you're getting all the zinc you need.

Sources of Zinc in Your Diet

Many foods contain sufficient amounts of zinc, such as:

Oysters: the richest natural source of zinc, at 28-32 mg/serving
Beef: ~3.8 mg/serving
Turkey breast: about 1.5 mg/serving
Blue Crab: ~3.2 mg/serving
Whole grains and fortified breakfast cereals: about 2.3 to 2.8 mg/serving
Beans and legumes: ~1.2 mg/serving
Pumpkin seeds: ~2.2 mg/serving
Dairy: ~1 mg/serving

You can likely get enough zinc by consuming a variety of these nutritious whole foods. (For more ideas, visit our Complete Guide to Zinc on the blog.) Remember that zinc from animal sources is more bioavailable than from fruit and vegetable sources.⁴ If you follow a plant-based diet or you're taking GLP-1s and eating less, it's especially important to ensure adequate vitamin and mineral intake. Learn about the specific amount of zinc in your favorite foods on the USDA National Nutrient Database for Zinc.

Zinc is also available as a supplement and may be included in other mixed supplements you're already taking, such as magnesium or calcium.
