Medication use , particularly long-term metformin therapy, proton pump inhibitors, and H2-receptor antagonists, increases deficiency risk
B12 needs vary based on the cause of deficiency, symptom severity, diet, and absorption issues (such as pernicious anemia or digestive conditions)
This further emphasizes the vitamin's multifaceted role in maintaining not just energy levels and neurological health, but also cardiovascular wellness

High-dose B12 seems promising, mainly for those with a B12 deficiency or at risk
B12 injections may also be useful for those with gastrointestinal issues, older adults, vegans, vegetarians, and people with underlying health conditions that can restrict vitamin B12 absorption
