In my case it unequvocally did. First a for years persisting skin-rush on my back cleared up. Secondly I could see with higher doses of vitamin C how it indeed lowered HbA1c, despite prediabetic fasting glucose measurements. A cystitis suddenly disappeared. Walking disabilty from PAD decreased as soon as reaching above 6 g/d. But most impressive because working on the spot, per teaspoonfull in a glass of water it works like a charm in quitting any sneezing-fit from rhinitis in its tracks.
