5 Best Zinc Supplements for Seniors: Price and Reviews 2021

Zinc is another 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.

Zinc deficiency is common in seniors, which may negatively impact the immune system and increase the likelihood of COVID-19. Its deficiency can play an essential role in the aging process and cause the nervous system’s degenerative diseases.

In the United States, about 12 % of the population is probably at risk for zinc deficiency, and as many as 40% of the elderly have a zinc deficiency. Experts say it is mainly due to inadequate dietary intake and less absorption of this essential nutrient.

Even more popular at the moment is the role of zinc and the potential benefits against COVID-19. This is probably one of the reasons that's driving the demand on zinc related products. There are many zinc studies underway and you can review the status of these trials on clinicaltrials.gov. As of March 2021, there are 19 studies that have been launched to investigate the benefits of Zinc against COVID-19.

Frequently Asked Questions

How to choose zinc supplements

When choosing a zinc supplement, it’s important to consider the type of zinc, dosage, and supplement form.

There are several types of zinc supplements. Some, such as zinc picolinate, may be better absorbed, while zinc acetate may be more effective at shortening the duration of the common cold (Trusted SourceTrusted Source).

Supplements contain several forms of zinc, including zinc gluconate, zinc sulfate, and zinc acetate. The percentage of elemental zinc varies by form. For example, approximately 23% of zinc sulfate consists of elemental zinc; thus, 220 mg of zinc sulfate contains 50 mg of elemental zinc. The elemental zinc content appears in the Supplement Facts panel on the supplement container. Research has not determined whether differences exist among forms of zinc in absorption, bioavailability, or tolerability.

How Much Zinc for Seniors?

Zinc dosage for senior: The Recommended Dietary Allowance (RDA) for zinc is 11 mg for adult male and 8 mg for adult female.

Men over age 60 do not usually meet their recommended daily zinc needs. On average, males in this demographic get 9.4 milligrams per day, slightly less than the recommendation, according to the Office of Dietary Supplements. In some cases, your doctor may suggest taking a daily multivitamin or zinc supplement to further boost your zinc intake. Zinc can be toxic at high doses, causing severe gastrointestinal problems. It is unlikely to get excessive amounts of zinc from your diet, but you can overdose on supplements. 

Zinc has two standard dosages (Examine). The low dosage is 5-10mg, while the high dosage is 25-45mg. The low dose works well as a daily preventative, while the high dosage should be taken by anyone at risk for a zinc deficiency.

Different forms of zinc contain different amounts of elemental zinc, which refers to the weight of the zinc molecule by itself (Note: Product labels tend to mark the elemental weight)
  • Zinc citrate is approximately 34% zinc by weight. For a dose of 50mg elemental zinc, take 146 mg zinc citrate. (Examine)
  • Zinc sulfate consists 23% of elemental zinc; thus, 220 mg of zinc sulfate contains 50 mg of elemental zinc (NIH).
  • Zinc gluconate is approximately 13% zinc by weight. For a dose of 50mg elemental zinc, take 385 mg zinc gluconate. (Examine)
  • Zinc monomethionine is approximately 21% zinc by weight. For a dose of 50mg elemental zinc, take 238 mg zinc monomethionine. (Examine)
  • Zinc picolinate (20% of elemental zinc) (Metabolics
  • Zinc ascorbate (15%) (Metabolics
  • Zinc chloride (48%) (Metabolics
  • Zinc carbonate (52%) (Metabolics
  • Zinc bisglycinate (25%) (Metabolics
  • Zinc oxide (80%) (FamilyPractice). Although the percentage of elemental zinc is high, do take note that zinc oxide is one of the least bioavailable form.
Taking zinc long term is typically safe for healthy adults, as long as the daily dose is under the set upper limit of 40 mg of elemental zinc (PubMed). Be aware that typical daily doses of zinc provided by zinc lozenges generally exceed tolerable upper limits for zinc, and for this reason, they should not be used for longer than about a week

Taking too much zinc can cause adverse side effects, such as decreased immune function, low copper levels, and reduced HDL (good) cholesterol levels.

Regarding the form, zinc supplements are available as capsules, lozenges, and liquids. For those who are unable or prefer not to swallow pills, liquid forms are likely a better option.

Before buying any supplement, it’s important to research high quality, trustworthy brands to ensure both safety and accuracy.

Look for supplements that are produced by reputable manufactures and free of large amounts of added ingredients like fillers, additives, and preservatives.

A good way to ensure the quality of a product is to look for ones that have been certified by a third-party company, such as NSF International or Underwriters Labs.

Foods that are high in zinc include oysters, crab, lobster, mussels, red meat, and poultry. Cereals are often fortified with zinc. Most multivitamin and nutritional supplements contain zinc.

Always check with your doctor before trying any new supplements or starting any new treatments. As your doctor may also prescribe supplements to you, do inform them about the supplements (including multivitamins, milk formula and nutritional supplements) that you are taking in order to avoid duplicates and overdosage.

The bottom line

Zinc is an essential nutrient that you need to get enough of in your diet. However, as not everyone is able to meet their need through foods alone, supplements can help reduce the risk of a zinc deficiency.

Of course, not all supplements are created equal. It’s important to look for high quality products that have been tested to ensure quality and accuracy.

If you’re concerned about your zinc intake, it’s worth speaking with your healthcare provider to see if a zinc supplement is a good option, as well as to determine an optimal dose.
