When people refer to B Vitamins they are essentially referring to water-soluble vitamins (excluding Vitamin C). These include:
-
Thiamine (vitamin B1)
-
riboflavin (vitamin B2)
-
niacin (vitamin B3)
-
pantothenic acid (Vitamin B5)
-
pyridoxoine (vitamin B6)
-
biotin, folic acid and cobalmins (vitamin B12)
At one time it was thought that there was a single Vitamin B but researchers later found that there are many that work independently. The importance of adequate B Vitamins in the diet cannot be over-emphasised. As water soluble vitamins cannot be stored by the body and any excesses are simply flushed away.
