B vitamins overview

There are many different types of vitamin B in our food and taken by some people as supplements. The different types of vitamin B do important work in the body.

B vitamins include:

Vitamin B1 (thiamine)

Vitamin B1, also known as thiamine, is a type of B vitamin that is essential for the metabolism of carbohydrates in order to release energy for growth, and to help keep nerves and muscles healthy.

Vitamin B2 (riboflavin)

Vitamin B2 ( riboflavin) is a B vitamin that helps the body release energy from metabolism of carbohydrates. It is essential for normal growth and cell repair including red blood cells and maintaining healthy skin, eyes and nervous system. Riboflavin changes tryptophan into niacin ( vitamin B3). It also helps protect cells from oxidative stress and helps reduce tiredness and fatigue.

Vitamin B3 (niacin)

Vitamin B3, also known as niacin or nicotinic acid, plays an important role in metabolism, helping the body release energy from dietary carbohydrate. Vitamin B3 also helps the body use protein and fats effectively. It’s essential for a healthy circulation and digestive system.
