A high potency B12 supplement containing 500μg of methylcobalamin and 500μg of
adenosylcobalamin; both are active forms of B12.
• Higher potency of 1000μg per tablet and beneficially contains active forms of
B12.
• Most products on the market are cyanocobalamin, which needs to be
enzymatically converted to the active forms in the body.
• Universally bio-effective and ideal for vegetarians and vegans.
• Methylcobalamin is used in methylation, adenosylcobalamin is used in the
mitochondria.
• B12 in supplements does not need stomach acid/digestive enzymes to release
it from protein. However, absorption of B12 from supplements still requires
intrinsic factor (released from the parietal cells in the stomach) and then uptake
is at the terminal ileum. Those with low intrinsic factor levels may fail to absorb
B12. If presented in a sublingual form the absorption problems are overcome.
• Methylcobalamin may be indicated to provide ‘methyl’ groups and for people
with specific genetic polymorphisms who do not recycle B12 effectively.
