Zinc safety
- The daily upper limit for adults is 40 mg of zinc from all sources, and it is much lower for children: 7 mg for ages 1 to 3, 12 mg for ages 4 to 8 and 23 mg for ages 9 to 13.[1]
- Too much zinc for a long time can lower immunity and HDL cholesterol and cause low copper levels, which can lead to numbness and loss of coordination.[1]
- Zinc can lower the absorption of quinolone and tetracycline antibiotics and of penicillamine. NIH says to take the antibiotic at least 2 hours before, or 4 to 6 hours after, zinc.[1]
- Zinc nasal sprays and gels have been linked to a lasting loss of smell, so skip them.[2]
Who Needs Zinc?
- What It Does – Zinc is found in cells throughout the body. It helps the immune system fight bacteria and viruses, and the body uses it to make DNA and proteins and to heal wounds.[1]
- Daily Amounts – NIH gives 11 mg a day for adult men and 8 mg for adult women, with 11 mg during pregnancy and 12 mg while breastfeeding. Children need 3 mg at ages 1 to 3, 5 mg at ages 4 to 8 and 8 mg at ages 9 to 13.[1]
- Higher Risk – People who have had gastrointestinal surgery or have Crohn’s disease or ulcerative colitis, vegetarians and vegans, pregnant or breastfeeding women, older breastfed infants and people with alcohol use disorder may have trouble getting enough.[1]
- Signs of Low Zinc – Low zinc can cause loss of appetite, slow growth in children, hair loss, frequent infections and a loss of taste and smell. Many of these signs have other causes, so ask your health care provider.[1]
Zinc Supplement Forms
- Common Forms – Supplements use zinc sulfate, zinc acetate, zinc gluconate and other forms. NIH says it is not clear whether one form is better than the others.[1]
- What Organic Means – Zinc is a mineral, so the mineral itself cannot be organic. A USDA Organic seal on a zinc product covers its farm ingredients, such as organic glycerin, fruit or leaf extracts, and the zinc is the same mineral either way.[4]
- Liquid Drops – Drops let you adjust the dose, and several of the products here are drops in a glass bottle with a dropper. Measure each serving and keep children’s doses within the age limits above.
- Capsules and Tablets – Easier to dose, with one serving per capsule or tablet. Check the milligrams of zinc per serving, since they run from low doses to 35 mg.
What to Check on a Zinc Supplement Label
- Amount Per Serving – Compare the milligrams of zinc with the daily amounts above. A 35 mg serving, such as the Naturelo capsule, is close to the 40 mg adult limit when you add food.[1]
- Supplement Facts Panel – It shows the ingredients, the serving size and the amount per serving.[3]
- Copper – Long-term high zinc can lower copper levels, and one product here adds copper. Ask your health care provider about long-term use.[1]
- Organic Seal – Look for the USDA Organic seal if you want a certified organic product.[4]
- Count and Price – Divide the price by the number of servings, not capsules or fluid ounces, to compare products fairly.
What the Research Says
The NIH Office of Dietary Supplements says some studies suggest that zinc lozenges or syrup speed recovery from a cold when started at the first signs, but they do not seem to change how severe the symptoms are, and more study is needed on the best dose and form.[1] It adds that zinc deficiency is uncommon in the United States and that people with age-related macular degeneration should talk to a doctor about the AREDS supplement, which uses 80 mg of zinc together with other ingredients.[1] The sheet notes that more research is needed on zinc and type 2 diabetes.[1]How We Chose These Products
