For obvious reasons, maintaining a healthy immune system has become increasingly important over the last several years. Vitamins and minerals like zinc are found in many immunity-focused supplements, lozenges, and over-the-counter medications. Zinc is especially popular. Studies show the best zinc supplements help reduce the duration and severity of common colds by up to three days.(1) You may be able to achieve optimal daily zinc levels from diet alone, but vegan, vegetarian, or other restrictive diets may benefit from the use of a zinc supplement.
Zinc is also recommended for skin and hair health, as well as an anti-inflammatory and energy booster.(2,3) We can't help but wonder; is there anything this mineral can't do?

Best Overall Zinc Supplement - Transparent Labs ZMO
SPECS
- Dosage: 2 capsules daily, 30-60 min. before sleep
- Form: Capsules
- Ingredients: Magnesium, zinc, oyster meat powder
Our best overall zinc supplement is a no-frills option—just clean, transparent ingredients. As a matter of fact, Transparent Labs ZMO was named for its commitment to simple ingredients: just zinc, magnesium, and oyster meat powder. Transparent Labs is the first brand to create a highly bioavailable zinc and magnesium supplement, meaning it's easier for your body to absorb these key nutrients. As for the oyster meat powder, it's rich in zinc and vitamin C, has shown promising antioxidant benefits, and may aid in reproductive health, making it excellent for both immune support and hormone production.(4)
The recommended dosage is two veggie capsules daily, taken on an empty stomach 30 to 60 minutes before turning in for the night for muscle recovery and sleep support. For a one-time purchase, Transparent Labs ZMO is about $0.96 per serving, but if the cost gives you pause, there is a subscribe-and-save program that gets you 10% off and free shipping on your order.

SPECS
- Dosage: 1 gummy (4g)
- Form: Gummies
- Ingredients: Zinc, vitamins B6 and B12, vitamin D, acerola cherry extract, European elderberry, echinacea root, ginger root
Capsules and tablets aren't for everybody, especially if you have difficulty swallowing, so a vitamin in gummy form can be a helpful and effective way to fill those nutrient gaps. While opinions are mixed as to whether or not gummies can absorb better than vitamins in pill form, when chewed thoroughly, gummy vitamins may have a higher bioavailability and therefore be absorbed faster by the body.(5)
KOS Immunity Gummies are our pick in this category, first, because they're easy to take and taste great. Second, these powerful gummies contain an "immunity blend" of zinc, vitamins C and D, elderberry, acerola cherry, and echinacea. These are all ingredients often associated with immune health and cold prevention. Elderberry has especially been shown to help treat and shorten the duration of cold and flu-like symptoms.(6)
Best For
- Those who prefer vitamins in gummy form
- Individually packaged for easy travel
- Users who want a blend of immune boosting ingredients
- Those looking for plant-based and sugar-free options

If you find it hard to reach optimal levels for vitamins through diet alone, we got you. With a curated blend of 10 essential vitamins you need, Ritual Essential for Men 18+ is our pick for the best liquid zinc supplement. While this multivitamin is not a traditional liquid or tincture-based, the beadlet-in-oil capsule is delayed-release, meaning it is designed to dissolve later for higher absorption levels that are much easier on your stomach. Multivitamins, and excess amounts of zinc, have been known to cause stomach upset in some individuals.
Ritual Essential for Men includes 2.4 milligrams of traceable zinc—sourced directly from Ogden, UT—per serving, well under the daily allowance of 11 grams for men. Keep in mind, Ritual Essential for Women 18+ does not include zinc.
Best For
- Men looking for an easy-dissolve form of zinc
- Third-party tested, non-GMO, vegan, and gluten and major-allergen free
- Those with stomach issues that can benefit from a delayed-release capsule

Best Budget Zinc Supplement - Future Kind Vegan Zinc

That may seem pretty high considering the recommended daily limit for zinc is 40 milligrams, but keep in mind, that only refers to elemental zinc, and with the zinc citrate only about 5 to 6 milligrams will be elemental. Regardless, if you experience headaches or stomach upset, discontinue your zinc supplement or consult with your primary physician.

- Form: Gummy vitamins
- Ingredients: Vitamin C, zinc citrate, sodium, organic black elderberry fruit, organic cane sugar
With a trio of immune-supporting ingredients coming from a vitamin, mineral, and antioxidant, Future Kind Organic Vegan Elderberry Vitamin C & Zinc Immunity Gummies are a mouthful to say, but easy to chew and swallow. These raspberry-flavored gummy vitamins are non-GMO and free from wheat, yeast, soy, and gluten. They are also free from animal derivatives—like gelatin—that are often seen in gummies, making these truly vegan. As for the "immunity trio" Future Kind Immunity Gummies contain 45 milligrams of vitamin C, 5 milligrams of zinc, and 150 milligrams of organic black elderberry fruit. All ingredients are closely associated with improvements in immune health.
One thing to be aware of with this product is that it has 3 grams of total sugar which includes 3 added grams of sugar. While that's relatively low, if you're watching your sugar intake these gummies may not work with your goals. At $0.83 per serving, they're affordable, but not cheap.

Benefits of Zinc
Zinc is a trace mineral and an essential nutrient that the body cannot produce by itself, so in order to meet our daily requirements for optimal health, we need to ingest zinc from either food or supplements. A well-balanced diet should always be your first choice but if you need additional support, it's perfectly fine to get your zinc in supplement form, especially if you are zinc deficient.
Here are a few of the benefits of adding zinc to your diet:
- Zinc may help boost your immune system and shorten the duration of the common cold by helping defend the body against bacteria and viruses.(14)
- Zinc has been shown to help with inflammation and potentially accelerate the healing of wounds.(15,16)
- Zinc may help treat skin issues like acne as sufferers of this condition may have lower zinc levels.(17)
- Zinc has been shown to help decrease the progression of macular degeneration (a retina issue) as you age.(18)
- Zinc has been shown to help treat the symptoms of psoriatic arthritis.(19)
Dosages
The recommended daily intakes for zinc are as follows:(1)
- Birth to 6 months: 2mg male, 2mg female
- 7-12 months: 3mg male, 3mg female
- 1-3 years: 3mg male, 3mg female
- 4-8 years: 5mg male, 5mg female
- 9-13 years: 8mg male, 8mg female
- 14-18 years: 11mg male, 9mg female
- 19+ years: 11mg male, 8mg female
Note: These levels can change based on preexisting conditions or pregnancy. Consult with your doctor if you're unsure about your optimal zinc levels.
What is the Best Time to Take Zinc Supplements?
According to the Mayo Clinic, the best time to take zinc supplements is approximately one hour before a meal or two hours after a meal.(20) Jessie Brownstein advises, "If stomach discomfort occurs, then it is good practice to take the zinc with a meal. Ideally, for most supplements, taking them at a consistent time daily is the most helpful with creating a habit of consistency." The Mayo Clinic does advise that you consult with your doctor if you plan on adjusting your zinc timing outside of the recommendations.
Next, always make sure to abide by the recommended dosages or timing listed on the product you choose. High levels of zinc can have adverse effects like nausea, dizziness, headaches, and vomiting.
What to Look For in a Zinc Supplement
Form
"In a zinc supplement it is important to know the source of zinc, and how much zinc it includes," says Brownstein. Zinc comes in several forms including those that are absorbed more easily like zinc picolinate, zinc citrate, zinc acetate, zinc glycerate, and zinc monomethionine. Each of these forms has their benefits, so you may consider trying another if one doesn't work for you.
Dosage
You'll want to be mindful of the dosage as overconsumption of zinc can have adverse effects. Zinc has a lower recommended dosage—8 milligrams for women and 11 milligrams for men—so you may be hesitant when you see that a few of the products on this list contain upwards of 50 milligrams of zinc per serving. How is that possible? That high number doesn't strictly come from elemental zinc—for example, zinc citrate is 34% zinc by weight—and will actually have a much lower amount.
Certifications
Certifications like "third-party tested" show that the supplement formula has been inspected for quality and purity by an independent organization. If you have dietary preferences or restrictions, certifications like vegan, organic, and non-GMO will be something to look for. Athletes should especially prioritize supplements that are NSF-certified for Sport.
Cost
Depending on the quality of the ingredients, zinc supplements can get slightly expensive. If you're needing to stretch your investment, rather than purchasing a supplement with zinc as the sole ingredient, look for a more comprehensive immune booster like a multivitamin to get your money's worth. We have several products on this list that have many actionable ingredients aside from zinc for overall health.
FAQs About Zinc Supplements
How should I take zinc supplements?
You'll want to take your zinc supplement as recommended by the manufacturer on the product label or by your doctor. A good rule of thumb is to take zinc one hour before a meal or two hours after.
Who should take zinc supplements?
Anyone can benefit from taking a zinc supplement as long as they're staying within the recommended daily dosage. Those suffering from zinc deficiency can especially benefit from supplementing with zinc. "Zinc supplements would be beneficial for anyone struggling with constant germ exposure, wound healing, or someone lacking in a diet full of zinc-rich foods," adds Brownstein.
Are there any potential side effects of taking zinc supplements?
Zinc is mostly safe at the correct dosage, but some users may experience side effects like nausea, diarrhea, vomiting, or stomach issues. If you fall into this category, you may consider taking your zinc supplement with food, changing the form of zinc you take, or discontinuing use altogether. Consult with your doctor if you are experiencing, or are concerned about, adverse effects from zinc supplementation.
What are the best sources of zinc?
The best sources of zinc are going to come from nutrient-rich foods like meat, fish, and seafood. Vegetarians can get zinc from sources like whole grains, fortified cereals, legumes, dairy, nuts, and seeds. Vegans can find zinc in chickpeas, lentils, quinoa, tofu, and a bevy of seeds. If you are unable to get an adequate amount of zinc from food alone, supplements with highly absorbable forms of zinc like zinc citrate, zinc picolinate, and zinc monomethionine are all excellent sources.
