Vitamin c: say you need the optimum amount which is 10,000mg. Vitamin c doesn"t prevent or cure the cold, reduces the severity of the common cold. Humans do not make our own vitamin c. There is an association between vitamin c and heart disease (increased intake of vitamin. C, decrease in heart disease) not a causative. Cholesterol: good: hdl, bad: ldl, worst: oxidized ldl (for plaque to form in the artery the cholesterol needs to be this kind) Vitamin c and cancer: converts nitrites into nitrosamines, converted into a cancer causing species, vitamin c prevents nitrites from becoming nitrosamines. Cataracts and vitamin c and slowly aging (connection?) Vitamin c prevents bed sore (made of collagen), bed sores occur from a break down of collagen, but taking this supplement prevents these.
