At the cellular level, B12 acts as a cofactor for two critical enzymatic reactions: Methionine synthase converts homocysteine to methionine, essential for DNA methylation and synthesis Methylmalonyl-CoA mutase involved in fatty acid metabolism and myelin production By restoring adequate B12 levels, injections enable normal red blood cell maturation in the bone marrow, correcting the megaloblastic anaemia
Monitoring Recommended Regular lab work and provider follow-ups are advised to ensure safety and track progress
Take, for example, a study that found several HLA (human leukocyte antigen) gene variants and other immune system gene variants that play a role in how vaccines work
Oral absorption in humans is unproven, but animal studies suggest possible systemic effects even with oral dosing6
Anticoagulants like heparin, warfarin, and newer direct oral anticoagulants (DOACs) present the most obvious interaction question
