Vitamin B12 is manufactured by bacteria and yeast and not by animals.  Meat and milk are full of bacteria because they are decaying substances and so these foods may have plenty of B12.

In a more natural world, vitamin B12 could be naturally available to vegans in the form of organic fruits and vegetables straight off the farm, pond water, river water or other natural drinking water etc. Nature always made provisions for us to get all nutrients. In fact some raw vegans find that their B12 levels are good without supplementation due to the abundance of fermented foods and drinks that they consume.

Vitamin B12 is so vital and the repercussions of low B12 are so huge that it’s just not worth it. Whether you have a deficiency or not can be determined by a simple blood test. Even if vitamin B12 deficiency is not currently present, it is likely to occur in the future. Everyone should keep checking annually or take a B12 supplement to be safe.

Vitamin B12 is required in minute amounts and can be stored in the body for up to 3 years.
