Although zinc is the best-known cold remedy, this essential mineral is also essential for cell growth and development. According to the NIH, the average adult needs eight to 11 milligrams of zinc per day, most of which is absorbed from food sources such as beans, meat, cheese, seeds, and oysters. Some people have trouble getting enough zinc in their diet, most of the time due to excessive alcohol consumption, a vegetarian diet, indigestion, gastrointestinal surgery, sickle cell disease , or older babies who are breastfed …

Supplements can be helpful if you are zinc deficient or feel you need to boost your immunity, especially if you feel like you are approaching a cold. In fact, research has shown that the combination of zinc and vitamin C found in some of our foods can help reduce symptoms of the common cold.

Here are the best zinc supplements:

Final verdict

While there are many high-quality zinc supplements on the market, we endorse Thorne Research's Zinc Picolinate (see on Amazon ) as the gold standard. Because the company is so committed to science and research, you can't go wrong with any of their products. We love this zinc because it is free of gluten, GMOs, artificial preservatives, and other major allergens. The picolinate form of zinc is also more easily absorbed than other types.

What to look for for zinc supplementation

Kind of:

Like most dietary supplements, you can take zinc in a number of ways. The most common are capsules, pills, tablets, gummies, and in liquid form. Gummies and liquid are definitely the best option for children or people who have a hard time swallowing tablets. Keep in mind, however, that gummies do not offer a more concentrated dosage than other types of zinc supplements and, like liquid formulas, may contain added sugars or sweeteners.

The shape:

There are several forms of zinc. Zinc picolinate, zinc citrate, zinc acetate, and zinc glycinate are more easily absorbed than zinc sulfate, but are usually more expensive.

Dose:

Pay attention to how many mg of zinc you need and what each tablet, capsule, gum, lozenge, or liquid offers. Keep in mind that more is not necessarily better, as we all have different needs. And you may experience nausea as a side effect of taking zinc supplements. Before taking any supplement, you should always check with your doctor to find out what your needs are.

Aim:

Looking for a daily zinc supplement or intermittent immunostimulation? Some zinc supplements can be taken once or twice a day, others several times a day for several days.

'Zinc is an essential nutrient that plays an important role in the body. It is essential for a healthy immune system and plays a key role in cell growth, protein formation, and wound healing. Meat, poultry, and seafood are excellent sources of zinc.
