In this Youtube video Markus Rothkranz explains the many misunderstandings of a vitamin B12 deficiency and how you can correct. He covers an array of concerns such as being a vegan or vegetarian, taking supplements and absorbing the b12.

He states that many people are fearful of their vitamin B12 levels and what it could mean for their health, such as brain damage or other health ailments. However, he states that this fear comes from a dramatic society that has a poor understanding of how the vitamin operates within the body.

He also explains that blood tests are not always accurate indications of actualy B12 levels within the body since B12 is technically stored within the liver and is not dectected in a blood sample. He goes as far as saying that blood tests are often “useless and misleading”.

B12 is stored in the liver and is easily accumulated over time. It is technically a bacteria that you can easily be exposed to. Due to over sterilization and heating of food, b12 is often lost in the process. However, your gut bacteria and probiotics have B12 that can be used and stored by the body.

However, although most Americans are meat eaters they are still low in B12. He states that if meat eaters do have higher B12 levels than non-meat eaters, it’s only because of the bacteria from the rotted flesh of the animal.

There are plenty of vegan sources of B12, such as seaweed, kelp and nutritional yeast. Bacteria in the gut also produces B12.

He goes on to explain that one of the main reasons for low B12 levels within the body is largely due to your body being unable to absorb it.

Regarding supplements, sublingual vitamin B12 is acceptable. However, taking supplements renders useless if you do not correct the underlying issue of you not being able to absorb the the b12 in the 1st place.
