IM B12 Booster
Type
IV Vitamin Therapy
Duration
10 min
An intramuscular vitamin B12 injection for rapid absorption. B12 is essential for red blood cell formation, neurological function, and DNA synthesis. IM delivery bypasses the gut, making it particularly effective for individuals with absorption issues, plant-based diets, or medications that deplete B12 stores.
Vitamin B12 (cobalamin) is a water-soluble vitamin that plays critical roles in red blood cell production, myelin sheath maintenance, DNA synthesis, and homocysteine metabolism. Deficiency can manifest as fatigue, weakness, numbness or tingling in extremities, cognitive difficulties, and megaloblastic anaemia. Several groups are at elevated risk of B12 deficiency: those following vegan or vegetarian diets (B12 is found almost exclusively in animal products), individuals taking proton pump inhibitors or metformin (which reduce absorption), older adults (who often produce less intrinsic factor), and anyone with gastrointestinal conditions affecting the terminal ileum where B12 is absorbed. Intramuscular injection delivers B12 directly into muscle tissue, where it is gradually absorbed into the bloodstream — bypassing the complex oral absorption pathway that requires intrinsic factor, stomach acid, and a functioning ileum. A single injection takes less than 10 minutes and is administered by a registered nurse. Many clients notice an energy lift within 24-48 hours, though the timeline varies. For ongoing deficiency, a series of injections may be recommended before transitioning to a maintenance schedule.
