Tag: Methylcobalamin absorption

According to the National Institutes of Health, only about 1.2% of high-dose vitamin B12 is absorbed passively, highlighting the inefficiency of standard oral supplements for many people. This makes understanding how to increase absorption of methylcobalamin crucial for those needing to correct or maintain their B12 levels effectively.

While the body relies on intrinsic factor for the efficient absorption of vitamin B12 from food, approximately 1-2% of an oral dose can be absorbed without it through passive diffusion. This alternative pathway is why high-dose methylcobalamin supplements are an effective treatment for deficiencies, even in individuals with intrinsic factor deficiency.
