Importance Of Zinc In Health


Would it surprise you to learn that many of us do not get the Recommended Daily Allowance (RDA) of vitamins and minerals necessary from our foods, even if we are consuming the suggested daily servings of fruits and vegetables?

Due to current farming practices, mass food production, processing, and cooking, our foods are less nutrient dense than they were in previous years. In fact, The U.S. Department of Agriculture says that it takes seven cups of today’s spinach to equal the nutrition that a single cup provided in 1960.

Vitamins and minerals help maintain cellular efficiency by activating enzyme systems that are essential to cellular function. Phyto-nutrients which are found in various forms of plant life are so important that nutritionists recommend at least 5 to 7 servings of fruits and vegetables per day, and suggest even more is better. Sadly, less than one in five Americans get even half of these amounts.

Important reasons for taking a multi-vitamin and mineral formula with phyto-nutrients:
  • To prevent diseases
  • To get the Recommended Daily Allowance of nutrients
  • Nutrient deficiencies in food
  • Consistent nutrient intake
  • To maintain cellular efficiency
  • The activation of enzymes essential to cellular function

It would be ideal if everyone could eat at least 5 to 7 servings of fresh fruits and vegetables a day, which is generally recommended by nutritionists in order to get the optimal daily nutrient intake. However, as mentioned above, modern day food practices account for measurable losses of necessary nutrients.

The Journal of the American Medical Association (2002; 287:3127-9) published a report by the Harvard researchers, Fletcher and Fairfield, stating that:

“Most people do not consume an optimal amount of all vitamins by diet alone. Pending strong evidence of effectiveness from randomized trials, it appears prudent for all adults to take vitamin supplements.”

The two Harvard doctors reviewed approximately 40 years of research and discovered that there was a link between vitamins and certain diseases. While this information has been believed by many health care professionals for decades, the proof is finally in the pudding. For example, these doctors reported “suboptimal levels of vitamins B-6 and B-12 are a risk factor for cardiovascular disease, neural tube defects, and colon and breast cancer; low levels of vitamin D contribute to osteopenia (mild thinning of the bone mass) and fractures; and low levels of the antioxidant vitamins (A, C, and E) may increase risk for several chronic diseases.”

The importance of zinc to our bodies:

Zinc is an essential trace element and is a component of about 300 metalloenzymes systems. Many of these enzymes play key roles in extra-cellular matrix remodeling; wound healing, connective tissue repair, inflammation, and cell proliferation. At Seagate Medical, we understand the growing need for natural treatments to improve the body's health. That is why we have brought epizyn (an fda approved, natural skin drug) to the marketplace. Our mission is to assist not only the general public in finding optimum ways to remedy their skin problems, but to provide a natural solution for those with recurring conditions that seek medical aid.

Zinc is essential for maintaining normal cell-mediated immune function. It is critical for the formation and activity of many enzymes and cells that play roles in the maintenance of a healthy immune system. It is also critical to other enzymes that promote a healthy free radical balance in the body.

Zinc Helps to Support:

Mental health, Healthy libido, Normal and healthy red blood cell levels, Normal fertility, Healthy and normal memory, Healthy and normal blood glucose levels, Monthly feminine health, Oral and teeth health, Cardiovascular health, Healthy eating patterns and attitude, Healthy urinary tract, Complements the immune system, Weight management, Cheerful disposition, Healthy and full hair, Healthy pressure within blood vessels, Healthy facial complexion, Chemical independence, Healthy body odor, Healthy eye tissue, Healthy intestinal and digestive tract.

Zinc is critical for the formation and activity of many enzymes and cells that play a role in the maintenance of a healthy immune system and has been used in the medical world for centuries.* In the 1800's, surgeons used zinc as an antiseptic/antibiotic after surgery because of its amazing support of body repair.

Because zinc naturally possesses antibacterial and anti-viral properties and is found in all the body fluids, including that of the eyes, lungs, nose, urine, and saliva, proper zinc levels work with the immune system in the defense of the body.* Because zinc is found in the body fluids, proper levels of zinc tend to decrease body odor, including foot odor, and promote the health of the throat with every swallow.* The body loses large amounts of zinc during perspiration. Therefore, athletes need to replace zinc regularly.*

Hunger is regulated by zinc and is the result of the body demanding nutrition. Zinc is important in metabolizing proteins, fats, and carbohydrates.* Tests show that zinc deficiencies increase the need for food by 50% over subjects who had proper zinc levels. Therefore, a person who is zinc deficient could consume up to 50% more food than is necessary, causing an undesirable increase in carbohydrates and weight increase due to overeating. Zinc is also involved in the process of gluconeogenesis, which is the formation of glucose from noncarbohydrates, such as protein or fat.*

Zinc is effective in hormone production and supports a healthy sex drive. Zinc promotes healthy prostate function and is important for the proper maintenance of the male reproductive system. It also supports the synthesis of testosterone and other male hormones.

Zinc is involved in many chemical reactions in the brain. It is essential in the development and continuous normal functioning of the central nervous system. There are many metalloenzymes and binding proteins in the body that require zinc for normal functioning. In scientific research, women who were given proper zinc supplements showed an increase of 20% in mental capacity over a 6-week period.

Zinc assists the body in making the 200+ enzymes that require zinc for their production.

Zinc supports the body's response to heat and occasional tenderness in various tissues.

Zinc is an essential trace mineral. Every cell in the body needs this nutrient and hundreds of body processes rely on it, from the immune system and the enzymes that produce DNA to the senses of taste and smell. Although the body does not produce zinc on its own, this mineral is readily available in drinking water and certain foods. Even so, a surprising number of adults fail to get enough of this mineral through their diet. Better food choices and a good multivitamin and mineral supplement can help compensate for such mild deficiencies.

Zinc is an integral part of human DNA and is necessary for cell division and synthesis. As such, it is critical that pregnant women get proper zinc levels during pregnancy for the health of the child within the womb. It is required for the nucleic acids DNA and RNA, the basic building blocks of the body.

There's now evidence that supplements may also be useful in providing the extra zinc needed to fight cold and flu symptoms. In addition, zinc has shown promise for speeding the healing of canker sores and sore throat, promoting recovery from skin injuries, reducing tinnitus (ringing in the ears), and controlling acne and eye problems.

Health Benefits:

Zinc is believed to promote a strong immune system by, among other things, revitalizing the thymus gland and its production of white blood cells. In addition, autoimmune diseases (chronic ailments linked to the improper functioning of the immune system, such as lupus, rheumatoid arthritis, or fibromyalgia) may also benefit from zinc supplementation.

Interestingly, the presence of too little zinc has been linked to a decreased immune response in older people. Again, supplemental zinc may be a viable remedy. In a study of 118 relatively healthy but elderly nursing home residents in Italy, researchers found that those given 25 mg of zinc daily for three months developed stronger immune systems.

By boosting the immune system, zinc may also protect against fungal infections and various infectious disorders, such as conjunctivitis and pneumonia. It also has anti-inflammatory properties.

Specifically, zinc may help to:

Fight colds and flu. When taken promptly at the first signs of illness, zinc lozenges can minimize the duration and severity of cold and flu symptoms. Research indicates that the zinc may actually destroy the cold virus, cutting the duration of an infection nearly in half. In one study, common colds disappeared about three days earlier in participants who sucked on zinc lozenges every couple of hours instead of on a placebo lozenge.

Only zinc in the form of zinc gluconate, ascorbate, or glycinate will fight a cold, however, so pick your product carefully. Avoid lozenges containing sorbitol, mannitol, or citric acid, as these chemicals, when combined with saliva, make zinc ineffective.

Accelerate healing of canker sores and sore throat. Zinc lozenges appear not only to boost your resistance to canker sores but also make them heal more quickly should they appear. The lozenges may even stave off a sore throat that's threatening to develop as a result of a cold.

Promote healing of skin wounds, eczema, rosacea, burns, and other irritations. Zinc repairs the skin's top layer in part by helping to process the essential fatty acids that encourage healing. Adding zinc supplements to your diet may therefore lead to more efficient recovery from burns, psoriasis, rosacea, hemorrhoids, and eczema, especially if the affected area is not healing well. The body also requires extra nutrients such as zinc to help repair burned skin and reinforce the immune response.

Control acne. In some studies, zinc has been linked to skin health because it enhances the immune system, reduces inflammation, and promotes healthy hormone levels. Acne may improve as a result. In one study, zinc when taken in conjunction with topical prescription antibiotic solutions, such as erythromycin and clindamycin, considerably increased the capacity of these medications to clear up the acne.

Because long-term use of zinc inhibits copper absorption, it should be taken along with that mineral. One study reported that participants taking 30 mg of zinc daily had a clearer complexion after two months than participants taking a placebo, at least according to the evaluating physicians. In a separate study, zinc performed as well as the standard acne antibiotic, tetracycline. Not all studies have found zinc to be beneficial for acne, however.

Reduce tinnitus. High concentrations of zinc are found in the inner ear. A Japanese study tested the theory that insufficient levels of zinc may therefore contribute to tinnitus. Researchers found that tinnitus sufferers with low zinc levels in their blood experienced an improvement in their symptoms when, after two weeks of zinc supplementation, their zinc levels rose significantly.

Treat eye problems. Zinc appears to boost the effectiveness of vitamin A, a nutrient well known for its role in keeping the eyes healthy. In addition, zinc plays a critical role in the functioning of the retina and the light-sensitive area known as the macula found within it. Supplements have been shown to slow vision loss in individuals with macular degeneration, a common cause of blindness in individuals over age 50.

Symptoms of the inflammatory eye condition known as conjunctivitis, or pinkeye, may lessen with zinc as well. In a French study of people with symptoms of conjunctivitis from seasonal allergies, zinc combined with antihistamines led to considerable improvement in 78% of the study participants. In the case of infection in the eye, keep in mind that even mild cases that fail to clear rapidly should be seen by a doctor.

Control diabetes. By improving levels of insulin (the hormone so important to regulating the body's energy supply) zinc supplements may help people with type 1 or 2 diabetes manage their disease more effectively. In addition, some people with diabetes have wounds that fail to heal well; this problem relates in part to the presence of high blood sugar levels and zinc may help to control problems.

Minimize digestive complaints. Zinc's ability to foster healing may make it valuable in treating ulcers and other digestive tract problems. Interestingly, individuals with inflammatory bowel disease often suffer from a zinc deficiency. Supplements can help to normalize zinc levels.

Protect against osteoporosis. By promoting mineral absorption and keeping bones healthy, zinc may help to prevent this progressive bone disorder and its associated disabling complications, such as fractures. Zinc is often taken with copper, which plays a critical role in keeping collagen--a protein that strengthens the bones and connective tissue--in good shape. At least six months of treatment with zinc/copper combinations are needed before bone-strengthening effects occur.

Treat hormone-related infertility problems. Zinc's effect on sex hormones may make it valuable in treating infertility in both women and men. Zinc plays a positive role in female fertility by promoting proper cell division, a process critical to the earliest stages of conception and fetal development. Similarly, in male reproduction zinc may well be necessary for adequate testosterone levels and sperm counts.

Reduce the size of an enlarged prostate. Zinc ranks among the key nutrients for the health of the prostate gland in men. Some evidence indicates that it may not only reduce an enlarged prostate but actually relieve symptoms of benign prostatic hyperplasia (BPH), a common but bothersome condition that can result in problems such as difficulty urinating and weak urine flow.

Zinc supplements are most appropriate for prostate problems (BPH, specifically) categorized as mild to moderate; check with your doctor to see if your case qualifies as such. In fact, a doctor should check your condition regularly every six months to track your progress.

Nourish hair. Zinc, along with other vitamins and minerals, promotes hair growth. It may even help slow the loss of hair and counter brittleness, particularly if the problems are due to an underactive thyroid gland. Extra benefits are derived from combining zinc with copper, as this mineral is an essential ingredient in melanin, a natural pigment in hair.
