Doses above 100mg daily show diminishing returns in NNMT inhibition the enzyme inhibition curve plateaus beyond 150mg while increasing the risk of methylation pathway disruption and homocysteine elevation

The most likely cause of the fatigue is l ack of production of creatine due to functional vitamin B12 deficiency (see below)

However, it can also be given slowly intravenously or subcutaneously (injected into a vein or under the skin)
