I'd been taking Na Asc mostly for years, and needed to take a lot of it to get any bowel symptoms at all, like say 2-3 grams 4 or 5x a day. Then I got some Ascorbic Acid tablets and they didn't seem to have much effect, so I bought a pound of Ascorbic Acid powder and I find it a lot more effective. I took 1.5 grams of it 2 or 3 times today in water and am getting loose bowels, so I think I learned something about what form of Vit C I should take.
What's a bummer for me is that I had just bought a 3 pound jar of NOW brand Buffered C Na Asc for about $40. Anyone know what I could do with that? I think I'm going to keep using Asc Acid C. I have low stomach acid and I am at times too alkaline, so Asc Acid sounds like the way to go for me.
