What is methylcobalamin? 

Methylcobalamin is the most active form of vitamin B12. It contributes, among other things, to cell growth and renewal, to the functioning of the nervous system, to the synthesis of neurotransmitters and red blood cells via hematopoiesis, and to the maintenance of the myelin sheath (the structure surrounding and protecting nerve fibers). Methylcobalamin is also involved in the proper functioning of the cardiovascular system via homocysteine.

What are the causes of a vitamin B12 deficiency?

The majority of vitamin B12 deficiencies result from malabsorption [5] due to the non-dissociation of vitamin B12 from its ligands (dietary proteins and haptocorrin) and a lack of intrinsic factor. The causes are related to a loss of activity in the digestive tract (gastritis, Helicobacter infection, pancreatic insufficiency, intestinal inflammation, medication, etc.). B12 Forte bypasses this assimilation problem by using a pure and bioavailable form of vitamin B12 maximizing its diffusion/passive assimilation in the small intestine.
