Vitamin B12 and its Importance in your Diet

We all read and hear about taking multivitamins and individual vitamin supplements but did you know the importance of vitamin B12 in your diet? Vegetarians and vegans in particular should read this article as often vitamin B12 can be lacking in a seemingly “healthy diet.” Equally, meat eaters should also read on as the way our body processes vitamin B12 actually changes as we age, meaning we might not be getting enough despite eating foods high in vitamin B12.

Vitamin B12

Vitamin B12 is one of the various vitamins that conforms the vitamin B complex. While you can get most forms of vitamin B from many plant-based food sources, vitamin B12 is found most commonly in meat, eggs and dairy products. Furthermore, vitamin B12 contains cobalt which means it can only be synthesized by bacteria; that is, the digestion of vitamin B12 requires the presence of special protein in your stomach known as “intrinsic factor”. Unfortunately, the proteins that help the body process vitamin B12 tend to diminish with age, meaning that even though you may have a diet high in vitamin B12, you may still be deficient in the essential vitamin.

Chronically low levels of vitamin B12 can lead to nerve damage, resulting in irreversible neurological damage.

Adults don’t actually need very much vitamin B12 in their diet, with the recommendation being around 2.4 micrograms per day, with a small amount stored by your body. The first signs of vitamin B12 deficiency are often unexplained tingling in your feet and hands
