Zinc has long been established as playing a vital role in helping to maintain a healthy immune system. In order to have a proper functioning immune system, you need an adequate amount of Zinc and Vitamin C in your system. This is because both components work synergistically together to contribute to the health of your body tissues & cells, bones, gums, teeth, skin & cartilage. Vitamin C is also an extremely important antioxidant.

What is Zinc & Vitamin C?
Zinc is an essential mineral that is found in almost every cell and is vital for numerous processes in the body. Zinc supplements stimulate the activity of several enzymes and is therefore involved in normal cell growth, healthy immunity and the maintenance of healthy bones.
Vitamin C is also known to have a number of biological functions. It is required for growth and repair of tissues in all parts of your body. It is also necessary to form collagen, an important protein used to make skin, scar tissue, tendons, ligaments, and blood vessels.
Why take Zinc & Vitamin C?
Zinc & vitamin C work synergistically together to help maintain the health of your body's tissues & cells, bones, gums, teeth, skin & cartilage. The combination offers overall health maintenance to the body and in effect its immunity.
Take Zinc & Vitamin C tablets if you:
Have lowered immunity
Are prone to colds & flu
You are following bad diets or are limiting calorie intake
You have recently undergone surgery, suffered an injury or those with skin problems
You drink alcohol excessively
How does Zinc & Vitamin C work? The science behind the secret…
Zinc is a mineral that has been used to help promote wound healing and a healthy immune system. Vitamin C also plays a major role in wound healing and is required for proper iron absorption. Vitamin C also helps in the growth and repair of tissues and helps keep teeth and bones strong.
Both Vitamin C and zinc possess antioxidant properties that help protect cells from harm caused by free radicals. Free radicals can speed up the rate of ageing and make you susceptible to a number of health problems and diseases.
A zinc deficiency may weaken your immune system and make you more vulnerable to a range of infections. Vitamin C may enhance immune system function.
"Both zinc and Vitamin C play vital roles in immune function and help fight and prevent infectious diseases, including pneumonia and diarrhoea infections" E. S. Wintergerst of Bayer Consumer Care in Basel, Switzerland.
Zinc & the Common Cold
Studies have shown that taking Zinc at the onset of a cold can help reduce the severity and length of cold symptoms.
A recent study, based on a review of 15 scientific trials, which included more than 1,300 participants, found that taking Zinc could reduce the duration of a cold if taken within 24 hours of the symptoms occurring. The study also found that participants who took Zinc for 5 months or more appeared to have a high immunity against catching colds.
The researchers included 15 trials involving 1,360 people in their analysis. Of these, 13 trials with 966 participants assessed treatment of colds with zinc. Two trials, with 394 participants, assessed prevention. All 15 trials were conducted in high-income countries among healthy people, and the participants ages ranged from one year to 65 years old. Zinc was provided in the form of syrup, lozenges or tablets.
Not all studies were useful for all of the analyses, but the researchers grouped the relevant ones together to assess their main outcomes. Overall:
A pooling of results from six studies showed that the intake of zinc was associated with a significant reduction in the duration of colds
Pooling five studies found that the severity of symptoms was also significantly reduced with zinc intake
People taking zinc were less likely to have cold symptoms beyond seven days of treatment when the five relevant studies were pooled.
Taking zinc for at least five months reduced the incidence of colds in the two studies that measured this outcome.
Two studies combined showed that school absence and antibiotic prescriptions were lower in people taking zinc for at least five months.
Wintergerst ES et al, Annals of Nutrition & Metabolism, 2006;50(2):85-94:
Immune-enhancing role of vitamin C and zinc and effect on clinical conditions
Vitamin C concentrations in the plasma and leukocytes rapidly decline during infections and stress.
Supplementation of vitamin C was found to improve components of the human immune system such as antimicrobial and natural killer cell activities, lymphocyte proliferation, chemotaxis, and delayed-type hypersensitivity. Vitamin C contributes to maintaining the redox integrity of cells and thereby protects them against reactive oxygen species generated during the respiratory burst and in the inflammatory response. Likewise, zinc under nutrition or deficiency was shown to impair cellular mediators of innate immunity such as phagocytosis, natural killer cell activity, and the generation of oxidative burst. Therefore, both nutrients play important roles in immune function and the modulation of host resistance to infectious agents, reducing the risk, severity, and duration of infectious diseases. This is of special importance in populations in which insufficient intake of these nutrients is prevalent. In the developing world, this is the case in low- and middle-income countries, but also in subpopulations in industrialized countries, e.g. in the elderly. A large number of randomized controlled intervention trials with intakes of up to 1 g of vitamin C and up to 30 mg of zinc are available. These trials document that adequate intakes of vitamin C and zinc ameliorate symptoms and shorten the duration of respiratory tract infections including the common cold. Furthermore, vitamin C and zinc reduce the incidence and improve the outcome of pneumonia, malaria, and diarrhoea infections, especially in children in developing countries.
The Council for Responsible Nutrition (CRN) States:
Nutrition experts at the Harvard School of Public Health have created an online version of a food pyramid with a notation recommending a "
daily multivitamin plus extra vitamin D (for most people)."
Recognizing the special nutritional needs of senior citizens, researchers at Tufts University designed a food guide pyramid for the elderly, which features a flag at the top as a reminder that supplements of calcium, vitamin D, and vitamin B-12 may be needed for optimal health. The American Academy of Nutrition and Dietetics (formerly the American Dietetic Association) has a policy statement emphasizing the importance of good food choices but also recognizing that supplements can help some people meet their nutritional needs.
Supplement use should be seen as one component of the search for a healthier lifestyle, including improvements in overall food habits and engaging in physical exercise.
A generous intake of calcium plus vitamin D demonstrably helps build optimum bone mass during childhood and adolescence and also slows the rate of bone loss that naturally occurs with ageing.
Nutritional supplements are helpful in addressing a woman's increased nutrient needs during pregnancy. Prenatal multivitamins with minerals are commonly prescribed to ensure that both the baby's and the mother's needs are met. In addition to meeting normal nutritional needs during pregnancy, a multivitamin can also play a critical role in protecting against some birth defects. An abundance of data shows that women who get 400 mcg of supplemental folic acid per day for one to three months prior to conception and one to three months after conception can substantially lower the risk of having a baby with a neural tube defect such as spina bifida.
While adequate nutrient intake is critical for all age groups, it may have particular significance for the elderly. Calcium and vitamin D supplements, as previously noted, can have a powerful impact on bone health, and the Surgeon General says it is never too late to benefit from improved intakes of these nutrients. Vitamin D may also reduce the incidence of falls in older people. Vitamin and mineral supplements have been shown in some studies to improve immune functionin the elderly.
Low zinc intakes are associated with an increased risk of infections, including pneumonia. Supplemental intakes of vitamin E have had a positive effect in decreasing upper respiratory infections in some studies. For these reasons, it makes sense to encourage the elderly to use multivitamin and mineral supplements.
The bottom line is that a healthy lifestyle must include a focus on dietary improvement. Generous intakes of the essential nutrients will support the normal functioning of the body and enhance health in a myriad of ways. The rational use of nutritional supplements, combined with a healthy diet, will contribute substantially to health promotion and disease prevention.
Is Zinc & Vitamin C right for me?
In order to have a proper functioning immune system, you need an adequate amount of Zinc and Vitamin C in your system. This is because both components work synergistically together to contribute to the health of your body tissues & cells, bones, gums, teeth, skin & cartilage.

Zinc with vitamin C - immune system
Health Article: Daily Mail:
The knowledge that vitamin C can help stave off or shorten the duration of colds is universal; what is less well-known is that the mineral zinc is also essential to help fight colds and provide a boost to a flagging immune system.
Vitamin C is a well-known antioxidant, which helps keep damaging free radicals that damage cells and contribute to ageing at bay. In normal health it also helps keep the body tissues healthy, and assists with the absorption of iron, another essential mineral.
More zinc is found in the human body than any other trace element except iron, and is mostly located in bone, muscle, the prostate (in men) and the retina. It acts as a vital component in the production of enzymes, can speed up wound healing, and plays an important part in the immune and reproductive systems. Men with prostate and infertility problems are often found to be lacking in zinc and may need supplements.
The average diet quite often provides less than the Recommended Daily Allowance of 15mgs zinc, especially in vegetarians.
Zinc with Vitamin C - immune system
Health Article: Daily Mail:
Vitamin C has for a long time been known for its ability to help stave off or shorten the duration of colds and flu-like illnesses, and in normal health it is also responsible for keeping the body's tissues healthy.
Aside from helping the body to absorb essential iron, Vitamin C acts as an antioxidant, and helps control the formation of free radicals that damage cells and contribute to ageing.
Although the daily recommended allowance of Vitamin C is around 60mg, it is well tolerated in far higher doses by the body, and only recently have scientists called into question the long-term safety and efficacy of 'mega' doses; generally an excess of this water-soluble vitamin seems to pass through the body without harmful effects.
Zinc is increasingly being recognised for the important role this mineral metal plays in human health. Like Vitamin C, it helps keeps free radicals at bay, but is also a vital component in enzyme production, wound healing, and plays an important part in the reproductive and immune systems.
Because of this, zinc combined with Vitamin C is a popular cold-and-flu remedy. Pregnant and nursing mothers require more zinc than other women.
