Vitamin B itself is a complex of different vitamins like: B1, B2, B6, B12, niacin, folic acid, biotin and pantothenic acid. These B vitamins are very important in metabolic activity and in facilitating the red blood cell (which carry oxygen throughout your body). They also help your body make protein and energy.

The sources of vitamin B are leafy green vegetables seafood, beans, peas, citrus fruits, whole grains (such as wheat and oats), poultry, meats, eggs and dairy products (like milk and yogurt). Some bacteria in our large intestine also prepare some type of B-vitamins.
The deficiency of vitamin B can cause the disease “Beri Beri”, cracked lips, weak muscles, malformation of red blood cells, affects normal growth and disturbs the nervous system.
