Vitamin C is an essential nutrient for the human body. Many living creatures are able to make their own Vitamin C internally through biological processes. The one notable exception is humans, we are not able to make vitamin C internally and therefore must obtain the vitamin through our diet. Vitamin C deficiency can lead to conditions such as scurvy (malaise, skin and gum issues) and atherosclerosis (thickening of artery walls).
Vitamin C has been shown to have anti-oxidant effects, meaning it has the potential to reduce oxidants which can cause certain cancers and other ailments in the body. Vitamin C is also used by the immune system to help fight infections. Vitamin C can also reduce the histamine response in our bodies when exposed to allergens. For those of us who are allergy sufferers, extra Vitamin C can help us reduce the histamines that cause our aggravating symptoms. Vitamin C has also been shown to reduce the amounts of lead found in the blood.
The suggested daily intake of Vitamin C by government food agencies range from a low minimum of 40 milligrams (United Kingdom) per day to 100 milligrams (Japan). The US defines the upper tolerable limit of Vitamin C at 2,000 milligrams per day. During times of stress from illness or allergies one should make sure they get more than just the minimum recommended amounts to help our body. There is some research to indicate that getting more than the recommended daily allowance of vitamin C is beneficial to the human body in many ways. So do yourself a favor and make sure you are getting sufficient Vitamin C.
