B12 Shot

Vitamin B12 (cobalamin) is a water-soluble vitamin critical for DNA synthesis, neurological function, and the production of red blood cells. Deficiency can present as fatigue, cognitive difficulties, peripheral neuropathy, and macrocytic anaemia, and is more common in individuals following plant-based diets, older adults with reduced intrinsic factor, and those with gastrointestinal conditions that impair absorption.

Intramuscular injection ensures complete absorption by bypassing the gastrointestinal tract entirely. The injection itself takes only a few minutes, and at One Thirty Labs the appointment slot is approximately ten minutes to allow for a brief health check and the injection itself.

At 700 DKK, the B12 shot is one of the quickest and most affordable treatments at One Thirty Labs. It can be added to any visit — for example, combining a B12 shot with a cryotherapy session or infrared sauna for a comprehensive recovery stack. No pre-booking consultation is required for B12 injections in most cases, though staff will confirm suitability during the health check.
