Science-Based Health Benefits of Zinc

Zinc is an essential mineral that is needed by the body to function properly. It is used in a variety of processes including energy metabolism, cell structures, regeneration and growth. Although zinc can be found in a variety of foods, many people are deficient.

Zinc is included in Thyroid SupportImmune Support and Hair, Skin and Nails Support by Beyond Vita.

1. Immune System Function

Low levels of zinc have been shown to contribute to impaired immune system function.1

Zinc supplementation has been shown to reduce the duration of illness in people with the common cold.2 A meta-analysis also found zinc can shorten the duration of symptoms of the common cold.3

Zinc also may be an important factor in the activation of immunoregulatory genes.4

A 2016 randomized double-blind placebo-controlled study found that 3 months of zinc supplementation increased T cell numbers and function in 54 participants.5

Multiple other studies have also shown the beneficial effects of zinc on the immune system.6,7,8

Zinc may help improve immune system function and increase immunity.

2. Thyroid Health

Normal levels of thyroid hormones are necessary for maintaining a healthy metabolism and weight.

Zinc is needed to convert thyroxine (T4) to triiodothyronine (T3) which is the most potent thyroid hormone. Low levels of zinc could result in hypothyroidism.9

In a 1994 study with 9 hypothyroid and zinc deficient patients, oral supplementation with zinc normalized T3 levels after 12 months. The researchers concluded that zinc may play a role in thyroid hormone metabolism.10

Zinc may help restore and normalize thyroid hormone levels.

3. Heart Health

Low zinc levels have been associated with atherosclerosis, heart disease and heart failure.11,12

Researchers also believe that zinc supplementation may be able to decrease arteriosclerosis and increase circulation.13

A 2015 meta-analysis found zinc supplementation significantly reduced trigylcerides, total cholesterol and LDL cholesterol which may help reduce the incidence of mortality from atherosclerosis.14

Zinc supplementation may help improve heart health by lowering cholesterol levels.

4. Skin Health

Zinc supplementation has been shown to decrease pimples and acne in a double-blind trial involving 56 participants.15 This action may be due to decreasing inflammation.16

Oral zinc supplementation may also reduce dermatitis which is an inflammatory skin condition.17

Zinc may help improve skin health by reducing inflammation in the skin.

5. Improves Mood and Depression

A meta-analysis of 17 studies found that depression is associated with a lower level of zinc in the blood.18 Increased zinc intake is also associated with a lower risk of depression.19

A 2010 study found that zinc supplementation may be effective in reducing depression.20

Zinc also improved mood in a randomized double-blind placebo-controlled trial with 46 participants.21

Zinc may help improve mood and alleviate depression.

6. Eye Health

Zinc may be able to enhance antioxidant capacity in the eye and reduce oxidative damage in the eye resulting from light exposure.22

Another study claims zinc may slow the advancement of age related macular degeneration.23

Zinc may help improve eye health by reducing retinal damage from light.
