Best Zinc Supplement – May, 2021 Reviews & Top Picks

You may mostly remember Zinc from its heyday in the late 90 were when it became the overnight craze to help prevent or cure a common cold.The good news is that it can prevent and shorten common colds.

Even better news is Zinc is purported to regulate hormones , aid in the storage of insulin in the pancreas, support immune function and wound healing, combat eczema, psoriasis, inflammatory bowel syndrome, promote male fertility, treat ADHD, combatting Alzheimer’s disease and down syndrome, and to encourage weight gain, among other possible benefits.

In fact, Zinc is essential for a well-functioning body. You may not know, however, that zinc is not naturally produced by the human body, meaning that you can only get zinc into your system through diet or by taking supplements.

There are countless first-hand accounts from folks singing the praise of zinc supplements. Men with low testosterone, women who are trying to regulate their hormones post-pregnancy, people prone to debilitating seasonal illness and more.

Information Every Informed Buyer Should Know when looking for the right Zinc Supplement:

There are seven different types of Zinc available in supplement form. Your body best absorbs most supplemental Zinc by attaching itself to another substance. The term ‘chelated’ is used to indicate that the zinc has been paired with organic or amino acids. There are a few non-chelated zinc supplements available, normally labeled as ‘zinc sulfate’ or ‘zinc oxide.’

Seven different types of Zinc

Zinc Orotate is neutrally charged and works best for quick and efficient absorption into the body through cells, making it the best to use for Zinc’s natural antioxidant properties.

Zinc Picolinate has been paired with amino acids but is not neutrally charged like the Zinc above Orotate. (Despite its higher acidity, it’s still known for very high bodily absorption rates).

Zinc Gluconate is often the most common Zinc supplement available due to its unusually long shelf life and ease of manufacturing, often making it a less pricey option. Zinc Gluconate, however, is merely a chemically synthesized version of Zinc and has been said to have a low bodily absorption rate.

Zinc Acetate is, like Zinc Gluconate, another supplement that contains chemically synthesized and altered forms of Zinc, however, unlike Zinc Gluconate, Zinc Acetate is said to have a higher bodily absorption and carries a lower price tag typically.

Zinc Oxide is most commonly used as a topical ointment for minor cuts and burns as well as a standard ingredient in sunscreen. It’s non-chelated, and some studies suggest that its absorption rate is not as high as other chelated forms of Zinc when found in supplement form.

Zinc Sulphate, like Zinc Oxide, is the non-chelated form of Zinc and has similar properties and effects.

Remember that zinc is always absorbed best your the body when a protein-rich diet accompanies it. Dosage is also important. It’s recommended that most adults receive between 9-12 mg of Zinc daily.

It’s always a good idea to ask for your doctor’s recommendations and carefully read label instructions.

All of the Zinc in this tablet is found naturally in fresh foods which are grown locally by organic and sustainable farmers and then milled and pureed for top nutrient content.

So again, if you’re looking for a sustainably made Vegetarian and Vegan product that boasts local fresh foods, this company from New Hampshire is probably the right fit for your supplement needs.

The ingredients list on this product includes organic spinach, organic beetroot, organic parsley, organic carrot, organic broccoli, and organic brown rice as sources of Zinc (though Zinc is also an ingredient listed).

This is also a Certified Dairy Free, Dairy Free, Soy Free, Non-GMO, Vegan, Farm Fresh and Kosher product that is tested for Herbicides and Pesticides.

Thorne Research’s Zinc Supplement is made from Zinc Picolinate, which is supposed to be highly absorbable. It also provides a 15 mg dose in each capsule, which is in line with the recommended daily quantity of Zinc.

It comes in capsule form, and though it contains some other ingredients, including Microcrystalline Cellulose, Hypromellose, Leucine, and Silicone Dioxide, they advertise that all parts are derived from natural sources. Their products do not include gluten GMOs, artificial preservatives, stearates, wheat, rye, barley, eggs, nuts, gluten, dairy, soy, corn, yeast, sugar or magnesium stearate.

According to Thorne Research, their products are always tested by MDs, PhDs, and NDs, and are tested in the first ingredients stage, halfway through production, and provide a finished product analysis to ensure that the purity of the ingredients is maintained throughout the production process.

They also partner with U.S. National Teams to support athletes, collaborate with research institutes to conduct clinical studies on their products, and partners with educational institutes and local charities.

Bulk Supplements Zinc Ororate Powder

There are quite a few reasons why you might choose to opt for a powder supplement as opposed to a capsule.

If you are interested in monitoring and changing your dosage if you can’t take pills, or if you are interested in mixing in a protein shake, this could be the right fit for you.

The other thing that might make this Zinc Ororate powder the right fit for you is that its only ingredient is Zinc Ororate powder- no fillers or inactive ingredients.

Bulk Supplements advertises that their product no other ingredients and that it is sugar, soy, dairy, yeast, gluten, corn, and additive free, so if you are worried about possible contaminants or allergens and prefer powder to capsules, this might be the right fit for you.

The downside to this product seems to be that it does not come with a measuring spoon and servings are suggested in a mg dosage – so you may want to use a cooking scale to figure out what the right dose is for you.


Pros and Cons

  • Low price
  • Contains highly absorbable Zinc Orotate
  • Accessible for those who can’t take capsules
  • Free of gluten, soy, dairy, sugar, yeast, corn, and other additives
  • Measuring device not included
  • Maybe less comfortable for some to take daily than a capsule

Solgar Zinc Picolinate, 22 mg 100 Tablets

The results are somewhat mixed as to whether Zinc Picolinate is as effective as Zinc Orotate, but it seems that Zinc Picolinate is still highly absorbable by the human body.

A 22 mg dose is higher than the recommended daily dose. However, this product still comes at a reasonable price point.

Solgar’s Zinc Picolinate is also free of additives, including Gluten, GMO ingredients, wheat, dairy, yeast, sugar, sodium, artificial flavors, sweeteners, and preservatives. They are also a Kosher product and suitable for vegetarians.

Due to the higher dosage of zinc in these capsules, however, you may want to choose a different product if Zinc supplements have upset your stomach in the past. Unlike some other products which are to be taken twice a day orally, Solgar’s Zinc Picolinate is to be made once daily by mouth, meaning that you get that high dose all at once (possibly inducing nausea).

Pros and Cons

  • Low price
  • Contains absorbable Zinc Picolinate
  • Suitable for Vegetarian and Kosher Eaters
  • Free of Additives, including Gluten, GMO ingredients, wheat, dairy, yeast, sugar, sodium, artificial flavors, sweeteners, and preservatives
  • Higher dosage of Zinc may cause nausea

Advanced Nutritional Research Zinc Ororate, 9.5 mg, 200 Capsules

As mentioned above, Zinc Ororate appears to have the highest natural absorption rate of all of the chelated and non-chelated Zinc Supplements.

Each capsule also contains 9.5 Mg of Zinc, the perfect amount of starting Zinc Supplement as the range for adults is between 9 and 12 mg.

This particular supplement also includes Magnesium, and the combination is intended to improve your Cardiovascular System, Digestive System, Hormonal System, Immune System, and Skeletal System

One tablet is to be taken twice daily, increasing the possible absorption rate.

Though Zinc Gluconate and Acetate are known for being cheaper options, this product comes on the lower spectrum of price for the type of zinc that it boasts.

Often the best or most efficient supplements are the most cost-prohibitive, so this is an excellent buy for the type and dose.

Pros and Cons

  • Low price
  • Contains Highly Absorbable Zinc Orotate
  • Dosage size is readily absorbable by the human body
  • Magnesium included
  • Some may not be interested in added Magnesium
  • Is not billed as ‘gluten-free,’ ‘non-GMO,’ or free from any other potential additives may affect your personal buying choices or allergies

Kal Zinc Ororate, 30 mg, 90 Tablets

This Zinc Ororate from Kal is in a sustained release tablet at a 30 mg dosage. This may be the only Zinc available in a time-release format.

Though it is a higher dosage, one might assume that the slow release might not induce nausea as some high dosage zinc products. It also contains Zinc Ororate, the type of Zinc that is supposedly most highly absorbable by the body.

This particular product is also marketed as vegetarian-friendly, though it does not make any claims about possible gluten, soy, nut, or GMO contaminants. The only ingredients listed are Zinc Ororate, Cellulose, and Stearic Acid.

This particular product is also available at a relatively low price-point, particularly considering that the Zinc Ororate available in these time release capsules is 200% the daily value.

If you are looking for a healthy daily supplement to combat a Zinc deficiency but are not interested in spending a lot of money, taking multiple pills a day, or are worried about becoming nauseous, this supplement may be right for you.

Pros and Cons

  • Contains highly absorbable Zinc Orotate
  • Vegetarian
  • Time release tablet
  • Large (time released) dose perfect for those who are Zinc deficient
  • Is not billed as ‘gluten-free,’ ‘non-GMO,’ or free from any other potential additives may affect your personal buying choices or allergies

Pure Encapsulations Zinc, 15 mg, 60 Capsules

Pure Encapsulations Zinc contains Zinc Picolinate, which has been touted as being highly absorbable by the human body. It also provides a 15 mg dose in each capsule, which is in line with the recommended daily quantity of Zinc.

 It comes in capsule form and is advertised to be free of any potential allergens. This includes wheat, gluten, egg, peanuts, magnesium stearate, hydrogenated fat, artificial sweeteners and colors, and ‘other unnecessary excipients.’

If you suffer from severe allergies or are looking for a slimmed down vegetarian supplement in capsule form, this may be the product for you.

Their website suggests that you may split the dosage by opening and divide the capsules, presumably in the instance that taking a full dose causes nausea, as Zinc is well known to cause nausea.

Pure Encapsulations also certifies that the raw ingredients used in their product are tested for identity, potency, and contaminants, including heavy metals, residual solvents, allergens, and pesticide residues.

For those of you looking for a clean and simple product and are worried about possible contaminants for any reason and are willing to pay a little extra to ensure this, Pure Encapsulations Zinc may be the right product for you.

Pros and Cons

  • Free of additives and marketed as non-GMO and hypoallergenic
  • Vegetarian and Vegan
  • Capsules are made with Raw Ingredients
  • Tested for contaminants
  • Higher price point

Solaray Bio Zinc, 15 mg, 100 Capsules

This Zinc Picolinate supplement by Solaray boasts a shallow price point and advertises ‘synergistic ingredients.’ Zinc Picolinate is highly absorbable by the human body, and Solaray claims that the B6 added to this supplement makes the Zinc even easier for your body to absorb.

The product is, however, manufactured with gelatin (for the capsule) and magnesium stearate, so if these are ingredients that you are staying away from keeping in mind that they are a part of this Zinc product.

Though they do not advertise that the product is free of additives, the bottle does indicate that Bio Zinc contains ‘zinc as amino acid chelates derived from rice, which does not contain the allergens associated with yeast, soy, or milk derived amino acid chelates.’ That being said, if allergies are a concern for you, it might be best to purchase a product that advertises its lack of potential allergy-causing substances.

This supplement is the right fit if the price is an essential factor for you and you are looking to supplement your daily vitaminintake with Vitamin B6 and are unconcerned with possible allergens or additives.

Pros and Cons

  • Shallow price point
  • Supplemented with Vitamin B6
  • Made with highly absorbable Zinc Picolinate
  • Not Vegetarian
  • Not free of artificial ingredients, potential allergens or fillers

EZ MELTS Zinc, 30 mg, 60 Capsules

Though this product contains Zinc Oxide, which is supposedly not as absorbable by the human body like other forms of Zinc, it does come in an easy to take ‘melt in your mouth’ style, perfect for those who want the ease of a capsule without the need to swallow with water.

The dose is higher than the recommended daily dose of Zinc, however, if you’re looking to thwart a cold, this more top treatment at a low price point may be the option for you.

It is also GMO-Free, Dye Free, Sugar-Free, and advertises only Natural Flavors, Sweeteners, and Colors. The price point isn’t unusually low but in the middle range.

Due to its flavoring and ease of use, it is also a good option for children. Again, be careful to avoid nausea with higher doses of Zinc.

Pros and Cons

  • Easy to take
  • Natural Sweeteners, Flavors, and Colors
  • Suitable for Children
  • Zinc Oxide is less absorbable by the human body
  • A high dosage of Zinc

Trace Minerals Research Liquid Ionic Zinc, 50 mg

This liquid Zinc product from Trace Minerals provides an easy solution for those who wish to add their Zinc Supplement to their food or beverages. It is formulated with Zinc Sulphate, which is not as absorbable by the body as Zinc Picolinate and Zinc Ororate.

However, there don’t appear to be a lot of options out there for liquid Zinc other than Zinc Sulphate.

This product is non-GMO and certified Vegan and gluten-free. If you are looking to take one supplement for a multitude of trace minerals, this option includes Copper, Chloride, Sulfate, and Boron as well as Zinc Sulfate.

Be warned, however, that the dosing is flexible and though the dropper is marked for a full and half sized dose, the upper limit for safe Zinc consumption for the human body is 40 mg, and this Zinc supplement is dosed at 50 mg (so only take half of the recommended daily dose).

It is recommended, however, that this product is added to a carrier food or beverage as the flavor is taste is unpleasant. If you are looking for something with other trace minerals that you can mix into food and drink, this product is a good option.

Pros and Cons

  • Easy to Use Liquid Form
  • Certified Vegan and Gluten Free
  • Includes other trace minerals
  • Bad Taste
  • Contains Zinc Sulphate

Zinc – Additional Information

If you are a vegetarian, you may be prone to a Zinc deficiency, as most Zinc-rich foods include seafood and meat, though whole grains and legumes also contain Zinc. It’s also particularly helpful if you are a drinker, as alcohol hinders the amount of Zinc that your body absorbs on a daily basis

Keep in mind that the safe upper limit for zinc intake in adults is 40 mg, so even if you starting to get the first scratches of that winter cold, make sure that you don’t overdo it on the Zinc supplements - always take supplements according to the labeling instructions or your doctor’s orders

Some reasons to consider taking a Zinc supplement include a desire to improve athletic performance, to support male or female fertility and reproductive health, to boost immune function (including preventing cancer!), to improve cardiovascular health, to prevent diabetes by becoming more sensitive to insulin, to promote whole brain health, to improve sleep as well as daily energy levels, to avoid depression and regulate hormones, and to improve cognition.


Zinc is an essential part of a well functioning human body, but not all Zinc supplements are made alike. Pay attention to factors such as the effectiveness of the type of Zinc used in the supplement (Chelated, Ororate, Picolinate, Gluconate, Acetate, Oxide, and Sulfate), possible additives that may not fit your lifestyle or may cause an allergic reaction, and dosage information.
