Boost your immune system - Vitamin C explained


Vitamin C (ascorbic acid) impacts the whole body and is essential for good health.  It’s a key component of collagen, a protein that forms the connective tissue in bone, muscle, blood vessels, teeth and gums. It’s also one of the most unstable vitamins and is easily oxidised when exposed to air. It can also lose its efficacy during cooking, processing, storage, harvesting and transportation. The body requires Vitamin C to absorb iron and it helps support natural resistance and immunity.



Vitamin C is an antioxidant. Antioxidants protect healthy cells, including muscle cells, from damage caused by destructive free radicals. Free radicals are the result of normal metabolic processes, like respiration and metabolising food. They can also be caused by aging and intense exercise.



Free radicals are unstable molecules produced in the body as a result of chemical reactions such as oxidation. They are unstable because they are missing an electron. When free radicals come into contact with other cells they can kill, damage or mutate those cells, which then become unstable themselves, setting off a cascading chain reaction within the body.



The body is equipped to detoxify itself to eliminate harmful toxins from the system. Unfortunately, the world in which we live is filled with toxins. The body’s cells are under constant attack from environmental toxins through the air we breathe, the food we eat and the water we drink. This means that the body must work extra hard to eliminate toxins to keep itself healthy.



Vitamin C is found in nature with substances called bioflavonoids. They are thought to be important in helping protect vitamin C from being oxidised. The bioflavonoids in an orange or a pepper are in the white fibrous parts. Rose hip is a natural source of vitamin C and also contain naturally occurring bioflavonoids. Bioflavonoids enhance the action and potency of vitamin C and serve as a powerful antioxidant.



A healthy immune system is the best defence against microbes, bacteria and viruses that would otherwise invade the body and destroy our health.  The immune system functions like a submarine.  While it is strong, the water stays out and the air pressure inside keeps you alive.  When it is weak, it ruptures and the water comes rushing in, sinking the ship and all aboard.


On a daily basis, our body uses antioxidant vitamins to boost the immune system, warding off such unwelcome visitors.  One of the most important antioxidants for this is vitamin C.

Vitamin C boosts the immune system by attacking the flu virus. This antioxidant vitamin also fights with bacteria.


Vitamins C antioxidants help to combat free radicals, allowing your immune system to be better equipped to combat invading bacteria and microbes.
