10 Best Zinc Supplements 2024

Zinc is a powerful immune nutrient known for its benefits for providing immune health support and inflammation reduction as well as for improving cold and respiratory symptoms, wound healing, acne reduction, and lowering the risk of age-related diseases. Research on atherosclerosis and diabetes mellitus suggests that zinc deficiency may contribute to low-grade systemic inflammation.

In a ConsumerLab survey of 9,647 people who use dietary supplements shows that the supplements which experienced the greatest growth in popularity in 2020 were those being promoted to prevent or treat infection with SARS-CoV-2, the coronavirus that causes COVID-19. Zinc supplements achieved the highest growth with +13.5% points.

Benefits of Zinc

Zinc is an important element required for the chemical reactions of over 300 enzymes, according to Oregon State University (OSU).

1. Supports a Strong Immune System

Zinc is necessary for the proper functioning of your immune system. That's why zinc is most commonly used as a supplement to help improve immunity, William Li, MD, president and medical director of the Angiogenesis Foundation and author of Eat to Beat Disease, tells LIVESTRONG.com.

2. May Shorten the Life of a Cold

As we mentioned, taking zinc at the first sign of a cold (within the first 24 hours) could reduce both how long the cold lasts and the severity of symptoms, according to a November 2011 meta-analysis in ​The Journal of Family Practice​.

3. Supports Eye Health

Specifically, zinc supplements might help slow the progression of age-related macular degeneration (AMD), Dr. Li says.

Malnutrition in older adults is a concern and often a cause for zinc deficiency. As such, research indicates that zinc supplementation may be able to have positive effects on AMD, according to a July 2020 paper in the ​International Journal of Molecular Sciences​.

4. Aids in Wound Healing

Zinc is essential in the healing process. People who have skin ulcers or low levels of zinc may benefit from supplementing with zinc, per the Mayo Clinic.

5. May reduce your risk of getting severe COVID-19

Does zinc help treat COVID 19? As of September 2022, there are more than 30 studies that have been published on the benefits of Zinc against COVID-19.

Types of Zinc

What's the best absorbed zinc supplement form? In order to answer the question and to understand it, we have provided an overview on the types of zinc and a summary on each zinc type below.

There are several types of zinc supplements. Supplements contain several forms of zinc, including zinc gluconate, zinc citrate and zinc picolinate. The percentage of elemental zinc varies by form. 

Choosing a zinc supplement can be confusing because there are so many different types.
  • zinc acetate
  • zinc angstrom
  • zinc carbonate
  • zinc carnosine
  • zinc chelate
  • zinc chloride
  • zinc citrate
  • zinc glycinate
  • zinc gluconate
  • zinc lactate
  • zinc l-aspartate / zinc aspartate
  • zinc methionine & monomethionine
  • zinc orotate
  • zinc oxide
  • zinc picolinate
  • zinc sulfate
For details, check out Types of Zinc Supplementation and Absorption.

What is the Difference Between Zinc Citrate, Zinc Picolinate, Zinc Glycinate and Zinc Gluconate?

According to the Beth Israel Lahey Health Winchester Hospital, a person supplementing with zinc will find their best options in the form of zinc citrate, zinc acetate and zinc picolinate because these absorb the best. Zinc gluconate is not among the top three, but it is absorbed better than zinc oxide. As far as cost goes, zinc sulfate is the lowest-cost option among the supplements.

Zinc Gluconate vs zinc picolinate - Zinc picolinate and zinc gluconate are zinc salts. One key difference between zinc picolinate and zinc gluconate is that zinc picolinate is derived from picolinic acid, whereas zinc gluconate is derived from gluconic acid. Zinc picolinate is 20% elemental zinc whereas zinc gluconate has 13% of elemental zinc.

Another difference between zinc gluconate and picolinate is that zinc gluconate, along with zinc acetate, has antiviral properties. This makes it a good form for making lozenges and nasal gels that don't contribute to the amount of iron digested and absorbed by the body, but it can fight viruses infecting the nose and throat.

The Mayo Clinic explains that zinc-based lozenges and syrups can be effective if they are used within the first 24 hours of the sign of symptoms. However, be careful — use of intranasal zinc has been linked with the loss of smell.

Although different forms of zinc have different amounts of elemental zinc that can be used by the body, the National Institutes of Health explains that there is not enough research indicating whether there are any superior forms in terms of absorption, bioavailability or tolerability.

One older study — published in the June 1987 issue of Agents Actions — did look at the effectiveness of three forms of zinc supplement and may shed a little bit of light on choosing zinc glycinate versus picolinate. The study looked at only 15 healthy human subjects who were divided into four groups. Over the course of four weeks, the four groups were tested with zinc picolinate, zinc citrate, zinc gluconate or a placebo.

Based on the zinc measurements in their hair, urine, erythrocyte and serum both before and after, zinc picolinate was the only form to raise zinc levels, at least in the hair, urine and erythrocyte. 

Based on these results, it seems as if zinc picolinate is most likely to absorb into a person's body, and zinc gluconate is the least likely. 

Zinc glycinate or zinc picolinate? In terms of zinc glycinate versus picolinate, the picolinate wins this one. Still, more research would be needed to know more about zinc glycinate versus picolinate, especially because this study was done so long ago.

Best Form of Zinc to Take?

Many forms of zinc supplements are available, some better than others for certain conditions. It's useful to understand your choices when deciding which is the best form of zinc for you. Many forms of zinc supplements are available, some better than others for certain conditions. It's useful to understand your choices when deciding which is the best form of zinc for you.

The best form of zinc is one that's chelated to ensure absorbability. Some good forms of this type of supplement include:
  • ​Zinc gluconate​, one of the most popular forms of over-the-counter supplements. It is made by fermenting glucose, so it has a long shelf life.
  • Zinc acetate is the best zinc supplement to treat the ​common cold​. Findings of a study published in Open Forum Infectious Diseases in 2017 recommended using acetate lozenges within 24 hours of the onset of a cold for a three-fold increase in the rate of recovery.
  • ​Zinc orotate​, made by binding zinc to orotic acid. It is the ​most readily absorbed​ zinc supplement on the market, according to Global Healing.
Inorganic zinc is not as effective or useable by your body as chelated zinc sources. For example, zinc sulfate​ is an inorganic form of zinc or zinc salt. Sulfate conflicts with calcium and may cause stomach irritation. 

Toxicity and Precautions

According to the National Institutes of Health, the upper tolerable daily limit for adults is ​40 milligrams​ of zinc. Intake of zinc above the recommended upper level could result from a combination of dietary supplements, multivitamins, food and food additives, ingestion of zinc-containing medications or household products.

Conclusion

If you think a zinc supplement is right for you, talk to your doctor about which form you should take. This is especially important because zinc can interfere with your body's absorption of copper and iron, so you might need to supplement those minerals as well.
