Product Specifications 5-amino-1MQ is a small molecule that blocks the activity of the enzyme called nicotinamide N-methyltransferase (NNMT)

labs looks like this: Normal range: 200 to 900 pg/mL (some labs use 160 to 950 pg/mL) Optimal range: 400 to 600 pg/mL Elevated: above 900 to 1,000 pg/mL (hypercobalaminemia) These ranges come from sources including UCSF Health and WebMD, though your labs specific cutoffs may differ

This can create a dilemma, as avoiding Vitamin B12 can lead to deficiency, while exposure to cobalt can trigger allergic reactions

Treatment should start urgently and should not be delayed for laboratory confirmation if neurological features strongly suggest B12 deficiency
