A healthy and robust immune system is vital for good health and fitness. Vitamins provide the building blocks that help keep our body healthy. Some vitamins are especially beneficial in boosting our immune system, strengthening its natural resistance power. These vitamins provide the necessary boost to the immune system helping the body fight against several infections and diseases.

A strong immune system is necessary as it attacks invading microbes, pathogen, infections and other microorganisms. Our Immune system produces antibodies which help in destroying these antigens. If the immune system is not supplemented with required nutrients and vitamins, it will collapse and lose the ability to fight against infections.

The immune system is mainly affected if the diet lacks in essential vitamins. Adequate intake of vitamins not only ensures a healthy immune system but also supports and maintains cardiovascular, nervous system and skin health.

Vitamins which are rich in natural antioxidants prevent the damage done by oxidative stress caused due to large numbers of free radicals. Oxidative stress and free radicals increase the risk of cardiovascular disease and atherosclerosis (hardening of the arteries) and weaken the immune system.

Vitamins are classified according to fat soluble vitamins and water soluble vitamins. The vitamins which can dissolve in fats and can be stored in the body are known as fat soluble vitamins namely A, D, E and K. Some vitamins need to be dissolve in water before the body can absorb them. These vitamins are known as water soluble vitamins namely C, B6, B 12, niacin, riboflavin and folate.

Recurring infections, slow wound healing, allergies, thrush, colds, and flu are some of the common symptoms which are associated with a weak immune system. If the immune system is not supplemented with essential vitamins and nutrients over a long period of time, it can lead to diabetes, cardiovascular diseases, joint complications and even cancer. Sleep is important not only for rest and rejuvenation, but also for supporting and strengthening the immune system. Avoiding stress, including a well nourished diet and regular exercise will goes a long way in maintaining health and boosting immunity.

Antioxidants which are found in substances such as Vitamin E, Vitamin C or beta caroteneplay a crucial role in maintaining and nourishing healthy skin tone by reducing wrinkles and preserving the skin’s natural health.

Vitamins and their metabolites are essential for a large number of physiological processes since they act as regulators of tissue’s growth and differentiation. Immune system vitamins also decrease inflammation and immune mediated tissue damage. They stimulate the immune response by activating T-cells, which protect the body against viruses and cancer cells.  It also contains polysaccharides, which are chemicals known to boost the immune system.

The B-complex vitamins are essential for the production of energy by the body’s cells, including cells of the immune system.

Vitamins maintain the overall wellbeing of the immune system. They play a major role in keeping our immune system strong, fighting against viruses, germs and other harmful substances. Immune system vitamins help to regulate body’s metabolism and assist in forming bone and tissue. If the body is not supplemented with necessary vitamins, then the immune system would collapse and eventually it will lose its resistance to fight against infection and other diseases.

If the body is deprived of these vitamins for a long period of time it can result in impaired bone growth, blindness, dry skin and in severe cases it can even lead to cancer or cardiovascular complications.
