Compound comparison
NAD+ vs NMN
Both sit in the same metabolic pathway studied in redox-biology and cellular-aging research. The difference is position in that pathway: NMN is a single-nucleotide precursor, and NAD+ is the finished dinucleotide coenzyme cells build from it.

Molecular data verified against PubChem and published literature. Molecular weights are average values.
NMN is a mononucleotide — a single nucleotide unit. Cells convert it to NAD+ when the enzyme NMNAT attaches an adenylyl group, producing the dinucleotide coenzyme. So NMN is studied as an input/precursor and NAD+ as the active redox cofactor. Researchers working on NAD+ metabolism often reference both.
Both are characterized reference materials in redox-biology, cellular-aging and metabolic research, with identity and reported purity confirmed by batch documentation. See the NAD+ redox primer and the research-peptide reference table.

Common questions
What is the difference between NAD+ and NMN?
NAD+ (nicotinamide adenine dinucleotide) is the active redox coenzyme — a dinucleotide. NMN (nicotinamide mononucleotide) is a single-nucleotide direct biosynthetic precursor that cells convert into NAD+. In short, NMN is an input and NAD+ is the finished coenzyme. Both are studied in redox-biology and cellular-aging research and supplied for laboratory research use only.
Is NMN the same as NAD+?
No. NMN is a mononucleotide precursor; NAD+ is the dinucleotide coenzyme synthesized from it (the enzyme NMNAT adds an adenylyl group to NMN to form NAD+). They have different molecular formulas and weights, shown in the table above.
Can I buy NAD+ for research?
Yes. TagPep stocks NAD+ as a 1000 mg lyophilized research vial with batch-specific analytical documentation, for laboratory research use only. NMN is shown here for reference and comparison.
