A deficiency in ademetionine and vitamin B12 in our metabolism is the rule in those aged 50 and above. The liver does not produce adequate amounts of ademetionine anymore, resulting in ademetionine deficiency. On top of this, the mucosal lining of our stomach deteriorates with age. As a consequence, the uptake of vitamin B12 is reduced, resulting in vitamin B12 deficiency.
A broad level of protection can be achieved by daily supplementation of ademetionine and vitamin B12.
Ademetionine is the most important donor of methyl groups within our cells.
