Vitamin B12 as the name suggests, is part of the B complex of vitamins, which are involved in energy metabolism, formation of red blood cells and the development and normal functioning of the brain and nervous system.
Ensuring healthy levels of B12 is vital for your energy production and keeping consistent energy levels throughout the day, helping you to stay active.
The body doesn’t naturally produce vitamin B12. Deficiency is more likely as we age and more prevalent in vegetarians and vegans, as vitamin B-12 cannot be obtained through plant, fruit or vegetable sources.
