[5] Disruption of these pathways leads to accumulation of homocysteine and methylmalonic acid, metabolic signatures linked to megaloblastic anemia and demyelinating neuropathy

In fact, a 2008 study found that after taking a 1,000 mcg oral supplement, only approximately 1.3% (or 13 mcg) of B12 was absorbed into the bloodstream
