The average non-vegetarian stores between 2,000 and 3,000 picograms of B-12 per day.
B-12 helps change homocysteine into methionine.
When this does not happen, homocysteine levels increase, which recent research has associated heart disease and deterioration of the arteries and nerves.
Although many vegan foods are said to have active B-12, few are proving to actually raise B-12 or prevent its loss.
There are a variety of symptoms of B-12 deficiency, which is a danger for vegans and live fooders. >
