Vitamin C or ascorbic acid in scientific terms is vital for our health and well-being. We need it to keep connective tissue like collagen strong so that it maintains the structural integrity of our organs and tissues. Without it we would suffer scurvy and lose our teeth for example or have sores which just do not heal. It also keeps our body’s cells in good order.
Chemical Name For Vitamin CÂ
You might see it called a more chemical sounding name:- 2,3-didehydro-L-threo-hexonic acid-g-lactone. The vitamin is an acid derivative of a 6-carbon sugar. You can see in the structure it has a diol group at carbons-2 and 3 which allows it to act as a very powerful reducing agent.
Sources Of Vitamin C
The best sources of vitamin C are oranges, blackcurrants, redcurrants, chilli peppers, green and red peppers, potatoes – especially the skins and green vegetables generally. A balanced diet is really what is needed to maintain our intake.
The Key Functions Of Vitamin C
Vitamin C or ascorbic acid has the following general health benefits:-
Vitamin C And Heart Health
Vitamin C is believed to be associated with good cardiovascular health although this has come through association by the consumption of various fruits and vegetables (Joshipura et al., 2001; Homberg et al., 2009; Martinez-Gonzalez et al., 2011). These studies noted an inverse association existed between dietary vitamin C intake, the levels of ascorbic acid in plasma and various cardiovascular ris factors, heart disease and mortality (CVM). Such studies however have limitations and did not rule out other factors known to be of benefit such as fiber consumption for example.
It may simply be the case that a good balanced diet is more significant in maintaining and improving heart health.
How Much Do We Need ?
We cannot make vitamin C – something we share with trout and other primates, but which most other animals don’t have to worry about! We need 40 mg of this vitamin a day as we cannot store it. There is no universally recommended daily intake of vitamin C but the World Health Organisation recommends a daily intake of 30 mg and in the UK, the RDA is higher at 60 mg.
Vitamin C supplements need to be taken with care to avoid overdosing as too much, say over 1,000 mg/day, causes, flatulence, diarrhoea and stomach cramps.
We know for example that people who have suffered heart attacks (acute myocardial infarction) have much lower than normal plasma levels of vitamin C. (Hume et al., 1972; Machtey et al., 1975; Jaxa-Chamiec et al., 2005) Leukocytes are the main cells in the body which contains reserve of vitamin C.
