yes I realise, which is the good thing about vitamin C. the fact you urniate it out, instead of going through the whole digesting process.
from wikipeida.org
Vitamin C exhibits remarkably low toxicity. For example, in a rat, the LD50 (the dose that will kill 50% of a population) has been reported as 11900 mg/kg.[35] For a 70 kg (155 pound) human, this means that 833,000 mg (0.833kg or 1.8 pounds) of vitamin C would need to be ingested to stand a 50% chance of killing the person. However, vitamin C could not result in death when administered orally as large amounts of the vitamin cause diarrhea and are not absorbed.[36] An extremely large amount of vitamin C would need to be rapidly injected by IV to stand any chance of killing a person. Robert Cathcart, MD, has used intravenous doses of vitamin C of 250 grams and reports that he has had no problems.[37] The Council for Responsible Nutrition has set an Upper Level (UL) of 2 grams, based on transient diarrhea. Their publication on vitamin C safety notes that [38]
“...very large doses of vitamin C have been taken daily over the course of many years, and only minor undesirable effects have been attributed with any certainty to the vitamin’s use[...] Clearly, vitamin C has a low order of toxicity.
