Can anyone tell me what the difference is, in terms of what I am likely to notice, and what differences are measurable or provable?
I asked on Amazon and another customer said they found Quali-C less acidic, which sounds plausible to me.
I am currently taking 15g+ of Peak Supps L-Ascorbic Acid, which they have confirmed is Chinese. I could ask for heavy metal test results, etc, I suppose. It's about 1/6th the price of Quali-C.
