If you do an internet search for wholesale ascorbic acid, you will find quite a few sites. The minimum however is 25 kilos (about 55 pounds/25,000 grams). I remember coming across one site that it broke down to less than $10 per kilo plus shipping. With it already made into tablets, the only palce I found needed a minimum order of 100,000 1 gram tablets at $16.90 per 1,000 tablets. I purchase my tablets from Costco in 500 gram bottles for $10.00. That is the cheapest I have found for tablets. If you find a cheaper source, please let me know.
