NMN
IMPORTANT: NMN is not a peptide; it is a nucleotide — a direct precursor of NAD+ (nicotinamide adenine dinucleotide), a coenzyme essential for cellular metabolism. Listed in this database because it is frequently associated with the longevity market. NAD+ levels decline with age, and NMN is researched to reverse this decline.

Mechanism of Action
NMN is converted to NAD+ in the body via the NMNAT enzyme. NAD+ is an essential cofactor for enzymes involved in mitochondrial energy production, DNA repair, sirtuin activation (proteins associated with longevity), and metabolic regulation. The theory is that increasing NAD+ may counteract the metabolic decline of aging.

Longevidade / metabolismo NAD+
OralDose usada em estudos recentes
Mononucleotídeo de nicotinamida. Aumenta níveis de NAD+ em humanos. Melhora sensibilidade à insulina em mulheres pós-menopáusicas com sobrepeso.
Benefits
Increased NAD+ levels
ProvenClinical studies confirm that oral NMN significantly increases blood NAD+ levels in humans.
View studyInsulin sensitivity
Under researchA clinical study in postmenopausal pre-diabetic women showed improved muscle insulin sensitivity after 10 weeks.
View studyPhysical performance
Under researchHuman studies show modest improvement in aerobic capacity and muscle function in middle-aged adults.
Anti-aging
UnprovenMouse studies show promising anti-aging effects, but translation to humans has not yet been demonstrated in long-term clinical trials.
Risks and Side Effects
Regulatory status in the US
Moderate(N/A)In 2022, the FDA reclassified NMN as an investigational drug (not a supplement), banning its sale as a dietary supplement in the US. Legal status varies in other countries.
Variable purity
Moderate(Variable)Independent analyses have shown that many commercial NMN products have significantly lower purity than stated on the label.
Internet vs. Science
What people say online compared to the actual scientific evidence.
Reverses aging
Partially trueWhat they claim
NMN is the fountain of youth — take it and your body rejuvenates years.
Actual evidence
It provably increases NAD+, but 'reversing aging' is an exaggeration. Human studies show modest benefits in some markers. Long-term effects on human longevity are unknown.
It's a peptide
FalseWhat they claim
Frequently sold alongside peptides in the biohacking market.
Actual evidence
NMN is a nucleotide, not a peptide. Peptides are chains of amino acids; nucleotides are compounds of a nitrogenous base, sugar, and phosphate.

PubMedFrequently Asked Questions
Is NMN actually legal in Brazil?
NMN is not specifically regulated by ANVISA in Brazil. Unlike in the US, where it was reclassified as an investigational drug, it is sold as a dietary supplement in Brazil. Verify the origin and purity of the product.
