I have seen it posted here several times about keeping sodium ascorbate on hand for illnesses - especially VPDs. (Mods, please leave this post here as I want the answers from those who currently are not vaxing.) I was at the health food store today, so I picked up "Sodium Ascorbate Crystalline Powder - 100% pure buffered vitamin C pharmaceutical grade pH 7.1". I want to make sure this is the right stuff before I open it! Is this the correct kind? Also, I need a link to the thread which mentions how much to give by weight. Thanks so much!
