It's ordinary vitamin c. I take it with orange juice so I get some citrus bioflavonoids.

Good Vitamin C

Posted by Crotchetymama on Apr 30, 2017 | Verified Purchase

I don't care for the huge doses of 1000, so finding this 500mg dose was great. I think since Vitamin C is water soluble, and excess just gets eliminated, why take huge doses all at once. I would prefer a 250mg, or even 100, which was common years ago. This product works, does not give me diarrhea, and is easy to take. I looked on the NIH site to see what they say about doses of Vitamin C. They say: Oral vitamin C produces tissue and plasma concentrations that the body tightly controls. Approximately 70%–90% of vitamin C is absorbed at moderate intakes of 30–180 mg/day. However, at doses above 1 g/day, absorption falls to less than 50% and absorbed, unmetabolized ascorbic acid is excreted in the urine .
