Is NAD+ a peptide?

No. NAD+ is a dinucleotide: two nucleotides joined through their phosphate groups. One carries an adenine base and the other carries nicotinamide, a form of vitamin B3. Peptides are chains of amino acids, and NAD+ contains none. Its formula and its role as an electron carrier put it in a different class of molecule entirely.

It sits in peptide catalogs because researchers often study it alongside peptides in metabolism work. MOTS-c, a mitochondrial-derived peptide, is one example. Like our peptides, each NAD+ lot is Made in China and tested by an ISO/IEC 17025 accredited lab for purity, identity, endotoxins, heavy metals and sterility, with reports posted in our COA library.
