Vitamin B Complex
General description
Vitamin B complex contains the full complement of vitamins found in the B group; these are listed below.
B vitamins are water-soluble. This means they are dissolved in water and your body doesn't store them. The B vitamins are related to each other and work closely in your body. For this reason, having all the B vitamins in your body helps your body work better.
B vitamins are found in many foods. So most people don't have a high risk of developing a deficiency if they follow a balanced diet.
There are many B complex supplements. They all have different amounts of the common B vitamins. Some also contain vitamin C and bioflavonoids. These are often called B complex with C.
The B complex includes:
-
Thiamin (B-1)
-
Riboflavin (B-2)
-
Niacin (B-3)
-
Pantothenic acid (B-5)
-
Pyridoxine (B-6)
-
Folic acid (B-9)
-
Cobalamin (B-12)
These are often also included as part of the B complex:
See each B vitamin for more information.
Unsubstantiated claims
There may be claims for use of vitamin B complex that haven't yet been proven through research.
Taking a B complex supplement may help increase energy levels, reduce stress, boost mood, and reduce symptoms of anxiety or depression. Always talk with your healthcare provider before taking a supplement.
