I totally agree... Vit C is the best.. taking it 4,000-6,000mg still ok... esp for adult.. if ur enzyme cant take it it will flush it out... like ur doc said paling2 "diarrhea"..

So dont worry... js take 2,000 mg per day..

Disclaimer: m not a doctor... but i do take large dose Vit C... and m still ok... hahahaha
