Best Liquid Zinc Supplements 2024

By Dr Frank Yap, MD -

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.

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.


While there are many food sources of zinc, including meat and shellfish, some people may be at a higher risk of not getting enough zinc in their diets (Source).

The zinc supplements in this review are all manufactured by reputable companies that follow Good Manufacturing Processes (GMP), use high quality ingredients, and test for purity and quality.

Reviews
We are using this for health of our immune system. This was recommended to us by a doctor who swears by it. As she is taking care of Covid patients, she believes this has helped her not catch it. So... we are trying it. We just got it and haven't had it for that long, so we'll see. But, we are taking other Zinc pills and believe that has helped us. This is stronger and will get into our system faster, so we're looking forward to positive results.

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 Source, Trusted 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.

It’s natural to have complex feelings about noticing signs of aging. You can embrace the beauty and privilege that it is to age, while also not love all of the physical changes that come along with it.  If you’d like to soften these signs but don’t want to go the injectables route, there are non-invasive products that can help. In the world of beauty products, there's perhaps no category more saturated than the anti-aging market. What to Look for in an Anti-Aging Product a. Vitamin C An antioxidant powerhouse, vitamin C is directly involved with collagen production in the body. Vitamin C is beneficial in anti-aging products for several reasons: It protects skin from environmental stressors, promotes cell turnover, and can fade dark spots which contribute to the appearance of aging skin.

Biggest Skin-Care Trends of 2024 - Allure

By Dr Frank Yap, MD -

Exosomes, neurocosmetics, and supercharged actives are the most innovative — and sometimes the most controversial — skin-care trends poised to revolutionize beauty in the next few years. We pored over the data and talked with experts to give you a snapshot of the top skin-care trends of 2024. Regenerative medicine will inspire your skin care. This year skin care won’t focus solely on addressing the signs of aging; it’s going to try to make cells behave younger, says Steven Cohen , MD, a board-certified plastic surgeon in San Diego. As with so many skin-care trends that have come before, this one is rooted in medicine — in this case, regenerative medicine, which is centered on developing and applying therapies to help the body heal itself. For example, stem cells — those biological blank slates that can turn into new skin, cartilage, or bone — are currently used in oncology to help the body produce new blood cells after high doses of chemotherapy. Again, this may sound like sci-fi (a t...

10 Best Cosmeceutical Ingredients of 2024

By Dr Frank Yap, MD -

A cosmeceutical is essentially a skincare product that contains a biologically active compound that is thought to have pharmaceutical effects on the skin. Both pharmaceutical and cosmeceutical grade skin care products actively effect skin at a cellular level, whereas cosmetic products have a shorter-term effect. They are usually used by doctors to restore pH, remove pigmentation, or restore the skin barrier. Cosmeceuticals must scientifically verify the claims stated on their packaging; as it is accepted that these formulations are backed by science, clinical studies, and rigorous testing. The main areas of concerns that these formulations address are ageing skin, sensitive/sensitized skin, sun damaged skin, acne/oily skin, loss of tone and elasticity, as well as superficial lines & wrinkles to encourage rapid cellular turnover that will renew and re-texturize the skin. Peptides composed of chains of amino acids give proteins their structure, and transport nutrients and signal mess...

Do nasal sprays actually work against COVID-19? Can I use nasal spray if I have COVID-19?  The COVID-19 pandemic has been roaring on for 3 years. During this time, the FDA has authorized many treatments  that help combat COVID-19. COVID-19 vaccines have also been recommended by the CDC ever since the first ones were authorized in December 2020.

Fenbendazole Joe Tippens Protocol: A Step-by-Step Guide

Image
If you have been diagnosed with cancer, or have a loved one that is suffering from cancer, chances are you have heard about the Joe Tippens Cancer Protocol. The Fenbendazole Cancer Protocol has been gaining rapid interest over the past years following some fenbendazole advanced cancer success stories. Joe Tippens founded the protocol after he was told a story about a scientist at Merck Animal Health that had been performing cancer research on mice. The research included injecting different types of cancers into different mice body parts. The scientists discovered, through trial and error, a product in their canine product line, fenbendazole, that was batting 1.000 in killing these different cancers in the mice. The scientist was later diagnosed with stage 4 brain cancer and was given a grim prognosis of only three months to live. She decided to try the fenbendazole, and after six weeks, showed a clean scan. Joe Tippens had been initially diagnosed with small...
