Vitamin B12 Shot

A quick intramuscular injection of vitamin B12 (cobalamin), the essential nutrient required for red blood cell formation, neurological function, and DNA synthesis. The injection delivers B12 directly into muscle tissue, achieving near-complete bioavailability compared with the variable absorption of oral supplements.

Vitamin B12 is a water-soluble vitamin that the body cannot produce on its own. It must come from dietary sources — predominantly animal products including meat, fish, dairy, and eggs — or from supplementation. B12 serves as a cofactor in two critical enzymatic reactions: the conversion of methylmalonyl-CoA to succinyl-CoA (essential for energy metabolism and myelin synthesis) and the conversion of homocysteine to methionine (relevant to cardiovascular risk and methylation processes). Deficiency is more common than many people realise. Risk factors include plant-based diets, age-related decline in intrinsic factor production (the protein required for intestinal B12 absorption), use of metformin or proton pump inhibitors, and gastrointestinal conditions that impair absorption. Symptoms of deficiency can be subtle — fatigue, difficulty concentrating, mood changes, and tingling in the extremities — and may be attributed to other causes before B12 status is checked. Higher Health's B12 injection is an intramuscular administration that takes approximately 10 minutes including preparation and a brief post-injection observation period. The intramuscular route provides near-complete bioavailability, bypassing the complex absorption pathway that limits oral B12 effectiveness in many individuals. The injection can be administered as a standalone visit or added to any IV therapy session. Many clients at Higher Health incorporate regular B12 injections into their wellness routine alongside periodic IV infusions. Dr. Tara Campbell ND and the clinical team can advise on appropriate frequency based on individual B12 status, dietary patterns, and health goals discussed during the initial consultation. The form of B12 used (methylcobalamin versus hydroxocobalamin) may be tailored based on individual methylation status and clinical needs — another advantage of receiving B12 through a naturopathic clinic rather than a generic injection service.
