Dear PF Forum, First of all, Happy New Year 2016, may your hopes, dreams, wishes and plans be fullfiled in this year. I'm interested in AntiOxidant. I've read: https://en.wikipedia.org/wiki/Antioxidant and http://www.1stvitality.co.uk/az/antioxidants/antioxidants.htm Those sites give me this antioxidant compound lists L-Carnosine C9H14N4O3 Ascorbic Acid C6H8O6 Lipoic acid C8H14O2S2 Are they really antioxidant, or there's a mistake in my understanding. Now about Negative Hydrogen Ion: H- Is it really an antioxidant? Thanks for the answers.
