b12 injection daily dose Dose: 7 Guidelines for Adults Cyanocobalamin Injection USP 1000 mcg/mL

For these situations you must see your GP

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

Notes that alternative pathways such as polyamine biosynthesis could compensate for raised SAM, that partial rather than total inhibition may be preferable to avoid compensatory mechanisms from an imbalanced SAM/SAH ratio, and that the consequences of sustained NNMT inhibition on systemic epigenetics remain unclear
