B12 deficiency can be sneaky and at times difficult to diagnose. You might be thinking, “my doctor just checked my B12 and Folate levels and he said they were fine” are you saying that I could still be B12 deficient? The answer is yes and you will learn why in the videos below but also why blood testing may not point an accurate pictures. B12 is necessary for so many functions in our body.

In fact if you are B12 deficient, Consider this:

Over the course of two months, a 62-year-old man developed numbness and a “pins and needles” sensation in his hands, had trouble walking, experienced severe joint pain, began turning yellow, and became progressively short of breath. The cause was lack of vitamin B₁₂ in his bloodstream, according to a case report from Harvard-affiliated Massachusetts General Hospital published in The New England Journal of Medicine.

It could have been worse—a severe vitamin B₁₂ deficiency can lead to deep depression, paranoia and delusions, memory loss, incontinence, loss of taste and smell, and more, according to another article in today’s New England Journal.

The human body needs vitamin B₁₂ to make red blood cells, nerves, DNA, and carry out other functions. The average adult should get 2.4 micrograms a day. Like most water soluble vitamins the body does not make vitamins B₁₂ it must be taken in from food or supplements we eat.

Another video worth watching. This video explains why its important to look at the cause behind B12 deficiency, the different kind of B12 that exist and information about MTHFR mutations.
