Factors that affect intake levels

Vitamin C can be destroyed by oxygen damage

Vitamin C is prone to be destroyed by heat

If you consume too much vitamin C, it will come out in your urine

Around 80 – 90% is absorbed when 30 – 120 milligrams are taken daily

Absorption drops to 20% when consumption exceeds 6000 milligrams per day

It’s important to get just the right amount of vitamin C instead of taking huge doses.

Toxicity

Mega doses don’t appear to be acutely toxic in healthy people;

Taking more than 2000 milligrams per day for prolonged periods may cause nausea, abdominal cramps, diarrhea and nosebleeds;

In people with kidney disease, excesses may contribute to kidney stones but not seen in healthy people;

Some experts say large amounts may stimulate free radical damage by enhancing oxidation;

People with hemachromatosis can experience problems with high Vitamin C intakes;

Vitamin C has not been proven to be a cure for the common cold but reduces the duration and severity of colds in some people.

So, make sure you get your Vitamin C or you could get really sick and pretty unattractive real quick.
