Having taken mega doses of vitamin C I'm aware of some of these side affects.
Nutrition and healthy eating
Vitamin C (ascorbic acid) is an essential nutrient. Still, it's possible to have too much vitamin C.
Vitamin C is a water-soluble vitamin that supports normal growth and development. Vitamin C also helps your body absorb iron. Because your body doesn't produce or store vitamin C, it's important to include vitamin C in your diet. For most people, a large orange, 1 cup (about 165 grams) of sliced strawberries, chopped red pepper or broccoli provide enough vitamin C for the day. Any extra vitamin C will simply be flushed out of your body in your urine.
For adults, the recommended dietary reference intake for vitamin C is 65 to 90 milligrams (mg) a day, and the upper limit is 2,000 mg a day. Although too much dietary vitamin C is unlikely to be harmful, megadoses of vitamin C supplements may cause:
Remember, for most people, a healthy diet provides an adequate amount of vitamin C.
"If you experienced those "side affects" it is a sure sign you NEEDED the antioxidants in the vitamin C you took! However, perhaps you should have moderated your dose to a level where you could live with the CLEANSING....."
Your vitamin C posts are total BS. There ARE significant side effect including kidney stones. The large doses of vitamin C has NEVER been proven to be beneficial - in fact, if you want skin cancer - take mega doses of vitamin C. And yes, I buy the same Costco vitamin C that you do but my ingestion is way less than what you claim.
In 1994, Robinson and two colleagues summarized the results of four mouse studies he had carried out while working at the Pauling Institute. Nearly all of the mice developed skin cancers (squamous cell carcinomas) following exposure to ultraviolet radiation. Altogether, 1,846 hairless mice received a total of 38 different diets. The researchers found that (a) the rate of onset and severity of tumors could be varied as much as 20-fold by just modifying dietary balance; (b) diets with the worst balance of nutrients had the greatest inhibitory effect on cancer growth; and (c) no cures or remissions were observed (although the researchers were not looking for this). In 1999, Robinson commented:
The results of these experiments caused an argument between Linus and me, which ended our 16-year period of work together. He was not willing to accept the experimentally proved fact that vitamin C in ordinary doses accelerated the growth rate of squamous cell carcinoma in these mice.
At the time, Linus was promoting his claim that "75% of all cancer can be prevented and cured by vitamin C alone." This claim proved to be without experimental foundation and not true. . . . Vitamin C increased the rate of growth of cancer at human equivalents of 1 to 5 grams per day, but suppressed the cancer growth rate at doses on the order of 100 grams per day (near the lethal dose), as do other measures of malnutrition.
