What Is Vitamin B Complex?
Vitamin B complex is a combination of essential water-soluble vitamins except vitamin C. This means that it doesn’t refer to a single type of vitamin, but to a combination of different B vitamins.
One interesting thing about vitamin B complex is that for a long time, it was thought to be just a single vitamin. Later on, researchers found that it was in fact several different types of vitamins, so they designated each vitamin with a number. This is why we have vitamins B1, B2, B3, B5, B6, and B12, which you might be familiar with. These designations refer to thiamine, riboflavin, niacin, pantothenic acid, pyridoxine, and the combination of biotin, folic acid, and cobalamins.
