Vitamin B12 Shot

A quick intramuscular vitamin B12 injection supporting energy metabolism, neurological function, and red blood cell production. Ideal for individuals with dietary restrictions or absorption difficulties.

Vitamin B12 (cobalamin) is essential for DNA synthesis, red blood cell formation, and the maintenance of the myelin sheath that protects nerve fibres. Unlike most vitamins, B12 is found almost exclusively in animal-derived foods, making deficiency particularly common among vegetarians and vegans. Even among omnivores, B12 absorption requires a complex process involving stomach acid, intrinsic factor, and ileal receptors — meaning that individuals with digestive conditions, those taking proton pump inhibitors, and older adults with reduced gastric acid production may develop deficiency despite adequate dietary intake. Intramuscular injection bypasses the entire gastrointestinal absorption pathway, delivering B12 directly into muscle tissue where it enters the bloodstream over the following hours. This route is particularly effective for individuals with known or suspected absorption issues. The injection takes only a few minutes and is administered by trained nursing staff at any of Qualevita's three Amsterdam locations. At EUR 75, this is one of Qualevita's most accessible treatments and serves as a practical standalone option for energy maintenance, or as a complement to the clinic's broader IV infusion and diagnostic programs. Regular B12 monitoring can be incorporated into any of Qualevita's health programs to verify that supplementation is achieving adequate serum levels.
