Just bought a tub of Vitamin B tablets, looked at the nutritional stats and they have massive amounts of the vitamins.
B-12: 5000% RDA
Thiamin (B-1): 3500% RDA
Also a lot of Riboflavin, B-6, Pantothenic acid, Niacin, and Folic acid.
Why do they put so much in? Is it healthy to ingest such large amounts?
