Dose-dependent GH response
Hydroxocobalamin, the form most commonly used in the UK, may cause: Injection site reactions (pain, redness, or swelling) Temporary reddish discolouration of urine Rarely, hypersensitivity reactions Very rarely, hypokalaemia in severely deficient patients when treatment is initiated (potassium levels should be monitored in severe deficiency) B12 injections are considered very safe, with no upper tolerable limit established, as excess B12 is excreted in urine
But heres the kicker most doctors are still using the same one-size-fits-all approach that ignores the fact that your body might process B12 completely differently than the person sitting next to you in the waiting room
Compared with the above methods, microbiome-based interventions are relatively more reliable and safer, including supplementary probiotics and fecal microbiota transplantation [131, 164]
