Bio Health -Buffered Vitamin C 500mg (200 Capsules)Vitamin C is considered to be the most useful of all vitamins for overall health maintenance. Its main source in the diet is from fruit (especially citrus) and vegetables.  It is an anti-oxidant and is essential in important functions including absorption of iron. There has been considerable research on Vitamin C and that humans need it in their diet is established.  Bio-Healthâ€ÂTMs Pure-fil capsules contain Vitamin C bonded with Calcium, making it non-acidic. The preparation will not cause stomach, intestinal or urinary tract distress as Vitamin C sometimes can and the Calcium content also helps to ensure the bodyâ€ÂTMs reserves are not depleted.  N.B. If you wish to take higher levels of Vitamin C we recommend Buffered C - Crystals. Suitable for vegetarians and vegans
