2018's 10 Best
ZINC SUPPLEMENTS

If you want your immune system to be healthy throughout the year, then a zinc supplement is what you need. Unfortunately, deficiency of zinc is a major concern around the globe. In the USA, approximately 12% of people are at risk of developing a zinc deficiency. So, what is zinc? And how exactly can it improve the health of your immune system? Read on to learn the answers to these questions and more.


What is Zinc?


Zinc is a mineral essential for your body. It is used in immune function, protein synthesis, metabolism, and many other processes. It is required to maintain your health, but only in very small quantities.

Zinc is present in all the cells of your body. It helps your immune system in fighting off viruses and bacteria. Your body also requires zinc to synthesize DNA and proteins. Your body requires zinc at all stages of development (pregnancy, childhood, and infancy). Zinc is a powerful antioxidant that fights the free radicals in your body and slows the process of aging.

Depression is a serious issue that can affect many areas of your life and the lives of your friends and loved ones as well. Getting symptoms of depression under control is highly important, and supplements can frequently be of help.


What are the Health Benefits of Zinc?


FIGHTS COLDS

Zinc is quite often used as an OTC remedy to fight colds. When you take zinc supplements for a minimum of five months, it makes you less prone to catching the common cold. Moreover, taking zinc supplements when you are already sick speeds your recovery. One study published in the Journal of the American Pharmacists Association proposed that zinc was effective in shortening the duration of common cold when given within a day of the onset of cold symptoms.

A review published in The Cochrane Database of Systematic Reviews found that in people who received zinc within 24 hours of the onset of symptoms of common cold, there was a significant reduction in the duration of those symptoms.

BOOSTS THE IMMUNE SYSTEM

A 2010 study published in the European Journal of Immunology states that your body requires zinc to proliferate and activate T cells (T lymphocytes). T cells help your body in two ways:

· By regulating and controlling immune responses and

· By attacking cancerous or infected cells.

A deficiency of zinc may impair the proper functioning of the immune system.

Another study published in The American Journal of Clinical Nutrition states that persons who are deficient in zinc have an increased susceptibility to various pathogenic organisms.





HAS ANTIOXIDANT PROPERTIES

Zinc has potent antioxidant and anti-inflammatory properties. These properties help it to combat oxidative stress and the diseases caused by it. These diseases include cancer and autoimmune diseases. Zinc has the capability to promote healthy division of cells. It prevents cancerous mutation of cells and inhibits tumor growth.

In a study published in The American Journal of Clinical Nutrition, potential benefits of zinc supplementation were studied in 50 adults. At the end of the one-year study, the group that received zinc had a reduced incidence of infections. The group also had reduced levels of markers for oxidative stress in the body than the placebo group.

HELPS COMBAT DISEASES RELATED TO AGE

A 2013 study demonstrated that nutritional deficits due to aging may result in decreased cellular zinc levels. The reduced levels of zinc result in inflammation throughout the body and impaired functioning of the immune system. Both of these contribute to the occurrence of chronic diseases. The study states that due to zinc deficiency, there are excessive oxidants present in the body. These oxidants cause increased damage to the DNA. Furthermore, zinc also aids in the normal repair mechanisms of the body. Due to zinc deficiency, the damage caused to proteins is increased as well. All these factors lead to a chain of events that result in various chronic and autoimmune diseases.

Another study demonstrated that supplementation with zinc can tighten leaky guts in patients with Crohn’s disease. Crohn’s disease is an autoimmune disease in which there is chronic inflammation of the small bowel.

HELPS IN TREATING DIARRHEA

According to reports published by the WHO, approximately 1.9 million kids below the age of 5 years are killed by diarrhea every year. Zinc supplements may help in reducing the incidence of diarrhea. In a study published in the journal PLoS Medicine, a national campaign to increase the use of zinc to prevent diarrhea in children in Bangladesh was followed. The study confirmed that zinc tablets are effective for not only treating diarrhea but also preventing future bouts of it.





PROMOTES HEALING OF WOUNDS

Zinc plays a vital role in preserving the structure and integrity of the skin. People suffering from chronic ulcers or wounds often have lower serum levels of zinc. They may also have a deficient metabolism of zinc. The skin creams used for treating skin irritations such as diaper rash often contain zinc. A study published in the journal Acta Dermato-Venereologia concluded that the healing action in leg ulcers was stimulated by applying zinc. Zinc acts by restoring the skin and reducing the growth of bacteria and inflammation. Local application of zinc on wounds corrects this local deficiency of zinc and also acts as a medicine.

PREVENTS AMD

Age-related Macular Degeneration (AMD) is a disease of the eye that results in vision loss. A 2001 study published in the Journal Archives of Ophthalmology states that zinc as an antioxidant prevents retinal cell damage. It helps to delay the progression of age-related macular degeneration and loss of vision.





PROMOTES FERTILITY

Many trials and studies have linked low serum levels of zinc to a low quality of sperm. A 2002 study demonstrated that total sperm count increased after treatment with folic acid and zinc sulfate in fertile and sub-fertile males. Furthermore, zinc modulates the levels of testosterone in males. A deficiency of zinc in healthy young males causes the significant reduction of testosterone levels, impacting libido and fertility. A study published in the Journal of Exercise Physiology studied the effects of zinc and magnesium supplements on physical strength and hormonal levels of males. The study found that free testosterone levels were increased in males who took 30 mg of zinc every day.

Zinc also has an impact on the fertility of women. This happens because adequate zinc levels are required during the maturation of their eggs. If there are low levels of zinc, the eggs may not mature, and ovulation may suffer.

MAINTAINS THE HEALTH OF THE HEART

Zinc is required to promote the health of the cardiovascular system. It acts as an antioxidant and anti-inflammatory and reduces oxidative stress and inflammation. The health of the endothelium, which is a thin cellular layer lining your blood vessels, depends on adequate zinc levels. Zinc also benefits the health of your heart by promoting healthy circulation. It does so by preventing the clogging of your arteries due to deposition of cholesterol. Hence, it acts as a natural therapy for those suffering from high blood pressure.





INCREASES LEAN MUSCLE MASS & IMPROVES STRENGTH

Zinc should be the first choice when looking for a supplement for your athletic needs. Zinc is present in every cell of your body and plays a key role during cell division. Hence, optimal levels of zinc are important to maximize athletic performance. According to recent research, zinc has a role to play in increasing the serum levels of three anabolic hormones important for your body. These hormones are testosterone, GH (growth hormone) and IGF-1 (insulin-like growth factor).

Several studies have demonstrated that low serum levels of zinc are associated with low levels of testosterone. This may affect multiple aspects of athletic performance such as strength, recovery, and percentage of body fat. Furthermore, researchers in Iran found that levels of both free testosterone and total testosterone were raised in cyclists post exercise. These cyclists received zinc supplements for four weeks. Additional research has also found raised levels of IGF-1 and GH after strenuous exercise. The raised levels of hormones result in increased strength and muscle building and improved recovery time.

Due to its ability to boost the immune system, zinc helps improve recovery time post-exercise in athletes. Furthermore, the antioxidant properties of zinc also help in recovery from exhaustive exercise by clearing free radicals.

IMPROVES INSULIN SENSITIVITY

Zinc is vital for proper functioning of insulin in three ways. It binds to the hormone insulin so that insulin is stored in the pancreas and released only when required to metabolize glucose. Zinc is also present in the enzymes required for attachment of insulin to the muscle cells when they take up glucose. This phenomenon is called insulin sensitivity. Reduced insulin sensitivity results in the decreased ability of insulin to attach to muscle cells. This results in a less-efficient uptake of glucose by muscle cells and chronic elevation of blood sugar levels. This leads to fat deposition in the body and the development of type 2 diabetes.

A review published in Biological Trace Element Research states that zinc is important in the synthesis and secretion of hormone insulin. Moreover, zinc deficiency is associated with insulin resistance and glucose intolerance.

Another study published in ‘The Journal of Maternal-Fetal and Neonatal Medicine demonstrated that supplementation with vitamin E and zinc for six weeks in females with gestational diabetes improved their lipid profile and insulin metabolism.





HELPS IN TREATING ACNE

Due to its anti-inflammatory properties, zinc is also useful in treating acne. A study published in the journal JAMA found oral zinc sulfate effective in treating acne lesions.

PLAYS A ROLE IN METABOLISM

Zinc is present in more than 300 different enzymes that take part in the degradation and synthesis of nucleic acids, proteins, lipids, and carbohydrates and the metabolism of many other micronutrients.


Recommended Dosage of Zinc Supplements


The adequate intake of zinc is essential, especially for children. This is because even a mild deficiency of zinc may hinder their growth and increase their risk to suffer from infection, respiratory illness, and diarrhea.

The dietary reference intakes (developed by Food and Nutrition Board situated at Institute of Medicine) for zinc are:

FOR INFANTS

0-6 months: 2.0 milligrams/day

7 months – 1 year: 3.0 milligrams/day

FOR CHILDREN

1-3 years: 3.0 milligrams/day

4-8 years: 5.0 milligrams/day

9-13 years: 8.0 milligrams/day

FOR ADULTS

Men, age 14 and above: 11.0 milligrams/day

Women, age 14-18 years: 9.0 milligrams/day

Women, age 19 and above: 8.0 milligrams/day

Pregnant women, age 19 and above: 11.0 milligrams/day

Breastfeeding women, age 19 and above: 12.0 milligrams/day





Possible Side Effects of Excess Zinc Consumption


There are many health benefits of zinc, but excessive intake may be harmful. Side effects of excessive intake of zinc may include:

  • Nausea
  • Reduced Appetite
  • Vomiting
  • Pain in Stomach
  • Diarrhea
  • Headaches
  • Reduced Urine Output

These symptoms appear within three to 10 hours after consuming zinc supplements. The symptoms disappear, however, soon after you stop taking the supplement.

Furthermore, a study conducted in 1991 found that the absorption of copper can be suppressed by consuming excess zinc.

Zinc in excess may also lead to iron deficiency. If you use nasal gels and sprays containing zinc, you may lose your sense of smell.





What to Look For When Buying Zinc Supplements


Consuming a zinc supplement is a way to treat or prevent zinc deficiency. But with the markets flooded with so many zinc supplements, how can you choose the best zinc supplements?

When buying a zinc supplement, read the labels. They will have information on food preservatives and dyes and potential allergens. In case, you are a vegetarian or vegan, look for a vegan-friendly or vegetarian-friendly label.

Buy a supplement that has fewer ingredients added in it, as many of them are not tested and not required. Moreover, they may have their own adverse effects and also dilute the product quality.

There are various forms of zinc supplements available in the market. Some of these supplements are absorbed better than others. The forms that are better absorbed are zinc citrate, zinc picolinate, zinc acetate, zinc monomethionine, and zinc glycerate.

Zinc supplements are either non-chelated or chelated. Chelated varieties attach zinc to some other compound such as an amino acid that helps with absorption. Zinc picolinate is a chelated form of zinc. You should talk to your physician before starting a zinc supplement.

You should avoid zinc oxides, as they are not absorbed easily. Zinc is also available in supplements that contain calcium. But you should avoid these. Zinc and calcium compete for absorption areas in your body. Hence, you should consume them separately.

Finally, buy zinc supplements from reputable brands, which have strong scientific backgrounds and offer strong values.
