The injection itself takes under 30 seconds and the full visit — including check-in and post-injection observation — usually wraps in under 10 minutes. Most patients come in on their lunch break.

Most patients start with weekly or bi-weekly injections for the first month to build their B12 stores, then transition to a maintenance schedule of one injection every 2 to 4 weeks. Patients on metformin, PPIs, or vegetarian diets typically benefit from more frequent dosing — Dr. Belkoff personalizes the schedule based on your labs and how you feel.

Most patients describe an energy and mental clarity lift within 24 to 48 hours after their first injection. Mood, sleep, and workout recovery improvements compound over the first 2 to 3 weeks. Patients with significant deficiency often describe the first shot as one of the most noticeable interventions they've ever tried.

We use methylcobalamin — the active, bioavailable form of B12 that your body uses directly without needing to convert it. Many clinics use cyanocobalamin, which is cheaper but requires liver conversion and contains a trace cyanide molecule. Methylcobalamin is especially important for the ~40% of people with MTHFR gene variants who can't efficiently convert cyanocobalamin to its active form.

No. At $25 per injection, our pricing is intentionally below most insurance copays — and we don't bill insurance for this service. HSA/FSA cards are typically accepted. The visit qualifies as a preventative wellness expense for most plans — check with your benefits provider.
