It aids hormone production, facilitates digestion, and even aids growth and repair of cells. Ah well, there’s more – but we ain’t telling everything here, read on to know all the benefits of zinc!

What Does Zinc Do To Your Body?

Zinc is found in cells throughout the body. It strengthens your immunity and even contributes to the production of proteins and DNA. It also helps in wound healing.

Zinc is also present in all the body tissues and is imperative for healthy cell division. It has antioxidant benefits too – the mineral fights free radical damage and can even slow down aging. That’s about zinc in a nutshell. For more detailed information on the benefits, keep reading.

What Are The Benefits Of Zinc? 

1. Builds Immunity

Benefits Of Zinc - Builds Immunity
Zinc was found to have a beneficial effect on the immune cells. In studies conducted on both young adults and the elderly, zinc supplementation was found to decrease oxidative stress and halt the generation of inflammatory cytokines. Zinc deficiency was also found to alter immune responses in animals – and can have a similar effect in humans as well.

The mineral works miraculously well to treat the common cold. It promotes faster wound healing as well. And as per reports by the World Health Organization, zinc supplementation might help boost respiratory health in children. Though more research is required, this is an encouraging move.

2. Helps Combat Cancer

An American study speaks of how zinc can aid cancer treatment. The mineral reduces the development of inflammatory blood vessels and induces cancer cell death. Other studies have stated that zinc can halt the proliferation of esophageal cancer cells. Zinc deficiency is quite common in cancer patients, suggesting a link between the mineral and cancer remission.

And since zinc is an effective anti-inflammatory and antioxidant agent, it helps prevent cancer.

3. Aids Diabetes Treatment

Zinc supplementation can have beneficial effects on glycemic control. As per other reports, women with prediabetes were found to be deficient in zinc.

Zinc has also been found to prevent amylin (a protein) from forming clumps in the body, which can contribute to diabetes and other chronic ailments. The mineral also balances insulin, which can help deal with diabetes. Zinc also allows for the adequate utilization of digestive enzymes – these help insulin bind to cells and ensure glucose is used as fuel and not stored as fat.

4. Protects The Heart

Studies have shown that zinc can protect the heart muscles. The mineral can prevent oxidative stress that might otherwise harm the heart in the long run. It helps the heart deal with oxidative stress and other related issues.

Zinc can also regulate heartbeat. Research showed that patients with congestive heart failure had excess zinc deficiency. The mineral also regulates the way calcium travels through the heart. Another American study shows how high zinc intake can help prevent angina pectoris (severe pain in the chest).

Zinc deficiency can also lead to high blood pressure, which might eventually lead to cardiac issues.


5. Might Aid Weight Loss

Studies have stated that obese individuals tend to have low levels of zinc. This means that boosting dietary zinc can aid weight loss. Obese patients on zinc supplementation had improved body mass indices, lost weight, and even showed improvements in triglyceride levels. This could be because zinc deficiency can provoke the body to store excess fat.

6. Can Boost Brain Health

Several studies have spoken about the beneficial effects of zinc on brain health. One such study talks about how the mineral has been successfully employed to treat certain types of schizophrenia. Zinc also plays a role in modulating the brain and the body’s response to stress. In fact, the highest amount of zinc in our bodies is found in our brains (in the hippocampus). 

High dose zinc supplementation was also found to enhance learning and memory.

7. Strengthens The Bones

Benefits Of Zinc - Strengthens The Bones


Zinc is found to have a restorative effect on bone loss. The mineral can be used in various forms to prevent and even treat osteoporosis. Zinc deficiency has also been linked to deterioration of bone metabolism. It can also stimulate bone formation and mineralization, two important aspects of bone health. This is particularly true as zinc helps in cellular protein synthesis.

Zinc has also been observed to be a precious trace element for oral health. The mineral is effective against commonly prevalent oral health issues like gingivitis, dental caries, and periodontitis.

8. Improve Vision

The macula (part of the retina) contains high levels of zinc. This mineral helps vitamin A create melanin, which is a pigment that protects the eye. Some evidence also suggests that zinc supplements can help prevent age-related macular degeneration.

Poor night vision and cloudy cataracts have also been linked to zinc deficiency.

9. Promotes Digestive Health

It has been found that people with zinc deficiency often experience digestive disturbances, the most common of them being difficulty in digesting protein. This is because zinc plays a role in the production of essential stomach acids.

The mineral can also help prevent several gastrointestinal issues. This stems from the fact that zinc can enhance the gastrointestinal epithelial barrier function, which can prevent related ailments.

Digestive issues, including diarrhea, are some of the common signs of zinc deficiency.

10. Can Be Helpful During Pregnancy

Research has shown that low birth weight infants whose mothers were on zinc supplementation during pregnancy had a reduced risk of diarrhea and dysentery.

As per the World Health Organization, zinc deficiency might lead to intra-uterine deficiency during pregnancy. Maternal zinc deficiency might also compromise the health of the infant and lead to poor birth outcomes. Studies show that over 80% of the world’s pregnant women are deficient in zinc. Zinc was also found to give favorable outcomes during pregnancy as well as lactation.

Also, zinc is the most important mineral for fertility. And low levels of zinc have also been linked to melasma (dark skin coloration that occurs especially during pregnancy).

11. Might Relieve PMS Symptoms

Zinc was found to relieve cramping and pain related to PMS. This might be because it improves blood flow to the uterus and also reduces inflammation.

12. Boosts Men’s Sexual Health

Zinc enables the male body to produce testosterone, which is one reason its deficiency can also lead to erectile dysfunction. Studies have shown that zinc supplementation can increase testosterone, thereby treating male sexual problems – erectile dysfunction being one of them. Consuming 30 milligrams of zinc a day was found to increase testosterone levels in men. 

Another study shows that a sense of smell could be important for libido – and that zinc deficiency can decrease the sense of smell.

This pretty much means that low levels of zinc indirectly decrease libido. Adequate zinc levels were also found to support prostate health.

13. Can Fight Chronic Fatigue

One Belgian study states how zinc supplements can help treat chronic fatigue syndrome (CFS). CFS is accompanied by increased oxidative stress – and since zinc fights oxidative stress, it can help fight the condition. As a result, zinc can also increase the energy levels.

14. Is Beneficial For Bodybuilding

Though there is less information on this, some reliable sources say that zinc can help with muscle growth and repair. It can also aid protein synthesis – which can be beneficial in bodybuilding.

15. Detoxifies The Body

Zinc can help in detoxification by enhancing the function of the liver and kidneys. Zinc deficiency is often linked to liver cirrhosis, and adequate levels of the mineral can prevent oxidative liver damage. The mineral is also helpful in preventing kidney disease and keeping the organs functioning perfectly.

16. Treats Tinnitus

Benefits Of Zinc - Treats Tinnitus


Studies show that patients with tinnitus have low levels of zinc. Though we need more research in this area, zinc can be a potential treatment for tinnitus.

17. Treats Acne

Reports suggest that acne patients are usually low in zinc. The mineral is known to kill acne-causing bacteria. It also fights inflammation, which usually occurs when bacteria invade a blocked pore and cause severe irritation. Zinc also reduces the activation of keratinocytes – which are cells that produce keratin (a protein that binds the cells together). Excess keratin leads to blocked pores and acne.

These properties of zinc can make your skin clear. It might also help with scars and herpes. You can get creams and ointments from the pharmacy with zinc as the primary constituent. Check with your doctor before using them, though. The anti-aging benefits of zinc can also help reduce wrinkles and age spots.

18. Can Boost Hair Growth

Zinc helps you maintain healthy hair. A deficiency in the mineral can lead to the deterioration of the protein structure that makes up the hair follicles. Taking adequate zinc can help in this aspect.

Well, we are done with the benefits. But to enjoy these benefits, one must take adequate amounts of zinc.
