I found a place for that ascorbic acid. Came up as the best price on my price search. I'm ordering one too. It seems like it can't hurt one bit and actually looks like a very good thing to dose. Anyway, here's the link: http://www.nutriteam.com/servlet/the-Nutribiotic-Personal-Care-%26Grapefruit-Seed-Extract/start/76/total/87/Categories EDIT: There are different pH buffer grades. Make sure to get the one you need.. probably the one closer to 8.4? IDK 2nd EDIT: It was on a different page the one Dingo showed. I updated the link above.
