B-12

Methylcobalamin B-12 for energy, red blood cell production and neurologic health.

5–10 minutes
Physician-supervised

Overview

Vitamin B-12 (methylcobalamin) is essential for DNA synthesis, red blood cell formation and myelination. IM administration is standard for patients with absorption issues, restrictive diets, or MTHFR variants.

Key benefits

  • Sustained energy
  • Supports mood and cognition
  • Aids red blood cell production
  • Bypasses gut absorption issues

How it works

A licensed clinician administers a single intramuscular injection (typically deltoid or gluteal). Most shots take under 10 minutes, including consultation.

Mechanism

Cofactor for methionine synthase and methylmalonyl-CoA mutase — critical to homocysteine metabolism and fatty acid oxidation.

Who is this for

  • Vegetarians and vegans
  • Patients on metformin or PPIs
  • Adults 50+ with declining absorption
  • MTHFR variant carriers
