Vitamin B: 8 essential nutrients

B vitamins are a group of eight basic nutrients that play a role in many organs and body systems. While they can work together in the body, they also perform their own specific functions.

In this article, we explore the function of B vitamins in the body and some key dietary sources of each.

We ‘re also looking at the signs of increasing B vitamin deficiency.

B vitamins are a class of water-soluble vitamins that play an important role in cell metabolism. While these vitamins have similar names, they are chemically distinct compounds that sometimes coexist in the same food. By general, dietary supplements containing all eight are referred to as vitamin B complexes.

There are eight B vitamins — collectively called B complex vitamins. They are thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), pyridoxine (B6), biotin (B7), folate (B9) and cobalamin (B12).

What are the benefits?

B vitamins have a crucial role to play in preserving good health and well-being. As building blocks for a healthy body, B vitamins have a significant effect on your energy levels, brain activity, and cell metabolism.

Vitamin B complex helps prevent infections and helps support or promote:

In women

B vitamins are particularly essential for pregnant and breast-feeding mothers. Such vitamins aid in the growth of the fetal brain and raising the risk of birth defects.

And for expectant mothers, B vitamins can raise energy levels, relieve nausea, and reduce the risk of developing preeclampsia.
