not vitamin A but i personally can’t have the vitamin C megadoses available in pharmacies. Apprently my body needs less vitamin C than most people, normally it’s very hard to have too much of it, but when i take a megadose like 1000mg (daily recommended is ~100mg) i get incredibly painful stomach cramps, whilst everyone around me is just fine

oh yea it causes the runs, and kidney stones. it doesnt seem as severe as vitamin A toxicity.
