Properties and Benefits of Zinc

Properties and Benefits of Zinc: Having zinc in our diet is a genuine reassurance of good health. As a mineral of great dietary importance, zinc stimulates the immune function by increasing the body’s response to bacteria and viruses. In addition to this, it supports digestion, helps keep diabetes under control and accelerates the wound healing process. Moreover, zinc increases energy levels, combats acne, increases fertility and helps us deal better with stress. Studies suggest it can contribute to increasing longevity, along with molybdenum. Overall, zinc should not lack from our diet.

Because it plays a vital role in protein synthesis and regulates the production of white blood cells, zinc is essential for keeping in good health. It is predominantly found in muscles, red and especially white blood cells, in our retina, liver, kidneys, pancreas, bones and skin. Sufficient dietary zinc can increase male fertility and support conception.

Zinc properties

Almonds, pecans, peas, ginger root, turnips and whole grains are all great sources of zinc. Meat is an excellent source of the mineral because the zinc it contains is highly bioavailable, meaning our body can absorb more of it than it does the one in plant sources. Some plant sources may also contain various compounds that bind to the mineral and partially inhibit its absorption, encouraging a deficiency. Increasing intake of plant sources of zinc or supplementing can help restore balance and ensure our body gets all the zinc it needs.

Because the salivary glands, the pancreas and other organs ‘secrete’ zinc, reserves may deplete rapidly, especially in men. Contributing to this loss of the mineral are our white blood cells which actively use zinc to function properly. For these reasons, a diet providing adequate amounts of zinc is needed to keep us healthy and ensure that our immune system and most important organs work properly.

Researchers believe that the human body contains two to three grams of zinc at all times. Though small, this amount can support more than 300 different body functions. Moreover, around 100.000 proteins in our body contain zinc, which makes it even more important to meet our daily requirements. The current recommended daily intake of zinc is around 10-11 mg and represents a minimum amount meant to prevent a deficiency. Emerging research suggests the minimum intake of the mineral should be up to 3 times higher. Still, the standard reference remains 10-11 mg for the average adult.

Zinc foods

Just as too little zinc is bad for us, too much zinc can have unpleasant effects on one’s health: exceeding our body’s daily requirements may cause nausea. Caution is required when taking food supplements in combination, such as zinc and ascorbic acid or other vitamins. While vitamin C is harmless and can be taken in rather high amounts without serious side effects except maybe for diarrhea (2, 3 or 5 grams), zinc will cause nausea when taken in excess.




As far as its health benefits are concerned, the mineral stimulates recovery after chronic infections and restores and enhances the body’s ability to heal itself. Adequate zinc supplementation will lead to faster and better wound healing. In men, zinc supports fertility as well as the proper development and overall health of the reproductive system. Because it is of crucial importance for the health of the male reproductive system, the mineral is considered a fertility booster.

In women, it supports birth and lactation in particular. Zinc is also important for hair and nail health. An intake of 15-45 mg of zinc per day can improve night vision, researchers say. There are also studies that suggest zinc is an efficient treatment method against acne. Certain topical anti-acne medications use zinc as their main ingredient for reducing bacterial count on skin and preventing acne breakouts.

Topical preparations containing the mineral are often prescribed for the treatment of mild, moderate and severe acne. In some cases, the mineral is believed to be more efficient than antibiotics. A more severe zinc deficiency can result in eczema, also known as atopic dermatitis, a chronic skin inflammatory disease.

Other deficiency symptoms include: impaired or poor growth, delayed bone formation, weight loss as a consequence of loss of appetite, loss of smell and taste, rough or pale and dull skin, sudden loss of hair, low blood pressure (hypotension), depression, fatigue and white spots on fingernails. Symptoms may vary depending on the severity of the deficiency.

    • According to research, zinc regulates hair growth and low levels of this mineral have been identified in individuals suffering from hair loss (Analysis of Serum Zinc and Copper Concentrations in Hair Loss) and Oral Zinc Sulphate in Treatment of Alopecia Areata (Double Blind; Cross-Over-Study). So yes, an adequate intake of zinc can help achieve a satisfactory hair density, but genetics also plays a role. Shininess is better achieved by the proper use of oils. Applying olive oil, coconut oil, argan oil, macadamia nut oil or other oils of your choice regularly on the hair can improve its aspect considerably because the oils help smooth hair cuticles (the outer layer of the hair), preserve moisture and prevent the hair from becoming dry and thus look unhealthy, brittle and dull. Moreover, oil masks act as protective agents, preventing further damage. As for color, stress and genetics are the main factors that contribute to premature hair graying. Copper is believed to hold the most benefits in this respect, while zinc is involved in other aspects of hair and scalp health (Serum iron, zinc, and copper concentration in premature graying of hair).
