What to look for in a Vitamin B12

Vitamin B12 is critical for energy metabolism and nerve function. Deficiency is common in vegans, older adults, and people on metformin or PPIs.

Quick checklist

• Form: methylcobalamin is the active form and generally preferred; cyanocobalamin is cheaper and also effective.
• Dose: 500–1000 mcg daily is a common supplement range; deficiency may need higher.
• Delivery: sublingual tablets and sprays bypass stomach absorption issues.
• Blood test: if you feel fatigued or have neuropathy, ask for a B12 and MMA test before supplementing long-term.
