what is Vitamin B? why is it good for us?

Answer 1

Vitamin B is a complex of eight water soluble vitamins. The name arises because it was once considered a single vitamin, much like Vitamin C or Vitamin D. Since later research has shown it is in fact a complex of chemically distinct vitamins that happen to often coexist in the same foods, the name has gradually declined in use, being replaced by the generic term "the B vitamins", the vitamin B complex, or by the specific names of each vitamin.

Vitamin B1, (Thiamine)
Vitamin B2, (Riboflavin)
Vitamin B3, also Vitamin P or Vitamin PP (Niacin)
Vitamin B5, (Pantothenic acid)
Vitamin B6, (Pyridoxine and Pyridoxamine)
Vitamin B7, also Vitamin H (Biotin)
Vitamin B9, also Vitamin M and Vitamin B-c (Folic acid) - important for pregnancies
Vitamin B12, (Cyanocobalamin)

The B vitamins often work together to deliver a number of health benefits to the body. B vitamins have been shown to:

Bolster metabolism
Maintain healthy skin and muscle tone
Enhance immune and nervous system function
Promote cell growth and division — including that of the red blood cells that help prevent anemia.
Together, they also help combat the symptoms and causes of stress, depression, and cardiovascular disease.

Vitamin B comes from a number of natural sources, including potatoes, bananas, cereal, lentils, chili peppers, tempeh, liver, turkey, and tuna. Nutritional yeast (or Brewer's yeast) is an especially good source of Vitamin B.

Another popular means of increasing one's Vitamin B intake is through supplements, purchased at supermarkets, health centers, or natural food stores.
