Vitamin B Complex

General description

Vitamin B complex contains all the vitamins in the B group. 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:

  • Biotin (vitamin H)

  • Choline

  • Inositol

  • Para-aminobenzoic acid (PABA)

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.
