The B vitamins complex refers to the eight B vitamins: the vitamin B1 (thiamine), the vitamin B2 (riboflavin), the vitamin B3 (niacin), the vitamin B5 (pantothenic acid), the vitamin B6 (pyridoxine), the vitamin B8 (biotin), the vitamin B9 (folate or folic acid) and the vitamin B12 (cobalamins or cyanocobalamin).
This structure is more complex and differs from the one of the other vitamins. It is not possible to state the indications of the vitamin B in general, as they differ according to the different B vitamins. However, the vitamins B6, B9 and B12 have similar indications. One can think about the prevention of cardiovascular diseases, osteoporosis or depression. But it’s different for the others! For example, the vitamin B1 plays a role in the metabolism of the carbohydrates and in the energy production while the vitamin B3 is useful in the production of red blood cells and the synthesis of sexual hormones.
Grains, yeasts, whole grains, nuts, dried or green vegetables, fruits, dairy products, giblets, etc.: these are examples of sources of vitamin B. For vegetarian or vegan people, the vitamin B can become an issue, and it is important to be careful about it.
