Good morning one and all. I seem to be feeling a bit under the weather with what I think is a stress induced virus ( Cold sore, mouth ulcers, generally feeling tired/ unwell) and want to increase my Vitamin C to help fight it off without increasing my blood sugars. I avoid fruits with seeds due to diverticular disease and don't want to take supplements if I can avoid them. Any suggestions for a natural source of Vit. C would be more than welcome. Many thanks.
