Vitamin B12 is one of those vitamins that is often misunderstood. Most people tend to have a good knowledge of vitamin C and D, how they get them and why they should be mindful of getting enough of each. That isn’t always the case for vitamin B12, but it should probably be. Vitamin B12 plays an important role in our day to day energy levels as well as our overall well-being.

A vitamin B12 deficiency generally leads to tiredness and a lack of energy and is thought to affect up to 1 in 10 people in certain age groups. While the main symptoms are associated with lethargy and tiredness, a deficiency can actually present in much wider symptoms that left unchecked and can cause serious long-term health problems.
