Injections are one option a provider may recommend when a deficiency is confirmed, especially when absorption is a concern
Unfortunately, studies on this topic have mainly focused on normalising serum B12 concentrations with oral supplementation and should be interpreted with caution since the specific goal of treatment in symptomatic B12 deficiency is alleviating symptoms, and NOT to normalize B12 concentrations in the blood
(as long as the causative factor for B 12 deficiency persists, therapy should be continued) Evidence from animal and human studies shows that B 12 also has neuroprotective and anti-inflammatory properties, 15 and intervention studies in humans have reported beneficial effects of better B 12 status or B 12 therapy in multiple sclerosis, 16 Parkinsons disease, 17 myalgic encephalomyelitis, 18 autism, 19 and (administering very high doses of methylcobalamin) in amyotrophic lateral sclerosis
