Description

How This Works

5-Amino-1MQ (5-amino-1-methylquinolinium) is a synthetic small molecule that selectively inhibits Nicotinamide N-methyltransferase (NNMT)^[1]. NNMT is a cytosolic enzyme that methylates nicotinamide (vitamin B3) using S-adenosylmethionine (SAM) as a methyl donor. In states of obesity and metabolic dysfunction, NNMT is often overexpressed in adipose tissue, depleting nicotinamide and reducing NAD+ availability^[2].

By inhibiting NNMT, 5-Amino-1MQ may spare nicotinamide for NAD+ synthesis via the salvage pathway, thereby activating SIRT1 (Sirtuin 1) pathways associated with mitochondrial biogenesis, fat oxidation, and metabolic flexibility^[3]. Preclinical studies indicate that NNMT knockdown or inhibition can protect against diet-induced weight gain and improve metabolic parameters without reducing food intake^[8][9].

Potential Benefits & Side Effects

Observations from preclinical and early research literature.

• May support reductions in fat mass while preserving lean muscle in animal models^[8][9].
• Associated with elevated NAD+ levels and SIRT1 activation in preclinical studies^[2][3].
• Enhanced grip strength observed in aged mice when combined with exercise^[10].
• Generally well tolerated; occasional reports of mild headache, transient jitteriness, or injection-site reactions.
• Long-term human safety data not established; this compound remains investigational.

Lifestyle Factors

Complementary strategies for best outcomes.

• Pair with a balanced, protein-forward diet tailored to energy needs.
• Combine resistance training and aerobic activity—preclinical data suggest synergy with exercise^[10].
• Prioritize sleep and stress management to support metabolic adaptation.
• Consider complementary NAD+ precursors (NMN/NR) per emerging stack protocols^[11].
