This is where personalized dosing comes in
This activates the vitamin so that your body can begin to use it and helps ease any irritation at the injection site
Reported applications include NNMT enzyme inhibition assays measuring 1-methylnicotinamide formation or S-adenosylhomocysteine release, intracellular target-engagement assays in differentiated 3T3-L1 adipocytes where 5-Amino-1MQ reduced intracellular 1-methylnicotinamide with an EC near 2.3 M (Neelakantan et al., Biochem Pharmacol, 2018), membrane permeability and Caco-2 transport characterisation, methyltransferase selectivity panels covering COMT, DNMT1 and PRMT3, and rodent studies of NNMT inhibition in adipose tissue and liver following the antisense knockdown work of Kraus and colleagues (Nature, 2014)
If your levels are in the intermediate range, your doctor may also test your levels of MMA and homocysteine
B12 injections are contraindicated for individuals with Lebers hereditary optic neuropathy, severe kidney disease, known cobalt or cobalamin allergy, and polycythemia vera
