They may benefit from a zinc supplement ( 1 , 2 ).

For example, pregnant or lactating women, vegetarians and vegans, people with gastrointestinal disorders, individuals taking certain medications like diuretics, and those who drink alcohol excessively are at a higher risk of developing a zinc deficiency ( 1 , 2 ). While there are many food sources of zinc, including meat and shellfish, some people may be at a higher risk for not getting enough zinc in their diets ( 1 ). Zinc is an essential micronutrient that’s needed for a number of critical processes in your body. For example, zinc plays an important role in immune function, cell division, and protein and DNA synthesis ( 1 ). We include products we think are useful for our readers. If you buy through links on this page, we may receive a small commission or other tangible benefit. Optum Store and Healthline are owned by RVO Health. Here’s our process . A good way to ensure high quality is to look for products that have been certified by a third-party organization such as NSF International or Underwriters Laboratories . Look for supplements that are produced by reputable manufacturers and free of large amounts of added ingredients like fillers, additives, and preservatives. Before buying any supplement, it’s important to research high quality, trustworthy brands to ensure both safety and quality. Zinc supplements are available as capsules, lozenges, and liquids. For people who cannot or prefer not to swallow pills, liquid forms are likely a better option. Taking too much zinc can cause negative side effects, such as decreased immune function, low copper levels, and reduced HDL (good) cholesterol levels ( 1 ). Due to potential side effects of excess zinc, it’s best not to exceed 40 mg per day unless under medical supervision. Most zinc supplements contain 15–30 mg of zinc per serving. Keep in mind the Tolerable Upper Intake Level (UL) of zinc is 40 mg per day for adults, 4–7 mg per day for infants, 7–23 mg per day for kids, and 23–34 mg per day for teens ( 1 ). There are several types of zinc supplements. Limited research suggests that some forms, such as zinc picolinate and zinc citrate, may be better absorbed than others, like zinc oxide. However, more recent studies are needed ( 3 , 4 ). When choosing a zinc supplement , it’s important to consider the type of zinc, dosage, supplement form, and product quality. Note that the serving sizes vary. Some supplements require two capsules per serving, while the serving size for others may be 1 teaspoon (5 mL), 1 mL, or 1 capsule, tablet, or lozenge. Generally, prices range from $0.08–$1.39 per serving, or $5.99–$38.90 per container, though this may vary depending on where you shop. General price ranges are indicated with dollar signs ($–$$$) below. One dollar sign means the product is rather affordable, whereas three dollar signs indicate a higher price range. Here are the 13 best zinc supplements to help you meet your nutritional needs. We chose the zinc supplements in this review based on the following criteria:
