Vitamin B12 is an essential water-soluble nutrient that the body cannot synthesize on its own — it must be obtained through diet or supplementation. It plays a foundational role in red blood cell formation, neurological function, and DNA synthesis, and acts as a critical cofactor in energy metabolism pathways. B12 therapy may be considered for patients with clinically appropriate needs, including those with dietary restrictions, absorption concerns, or laboratory findings that indicate deficiency or insufficiency. Your provider will review your health history and determine whether B12 is appropriate for your care plan.

• Wellness and preventive health clinics
• Weight management and metabolic health programs
• Compounding pharmacies (US-formulated)
• Patients with dietary, absorption, or lab-identified needs

One of the most structurally complex vitamins known — uniquely containing cobalt at its core, giving it the cobalamin designation. Injectable B12 bypasses gastrointestinal absorption entirely, making it the preferred route for patients with absorption concerns such as pernicious anemia, GI conditions, or post-surgical changes. Available in cyanocobalamin and methylcobalamin forms depending on clinical preference. Dosing frequency and formulation are determined by the provider based on lab values and individual health history.
