MOTS-c vs NAD+
Key differences, research and prices — side by side.
The key difference
MOTS-c is a 16-amino-acid peptide encoded by mitochondrial DNA. NAD+ is not a peptide at all — it is a coenzyme that every cell needs to turn nutrients into energy. Most human NAD+ research uses oral precursors such as NR and NMN.
| MOTS-c | NAD+ | |
|---|---|---|
| What it is | MOTS-c is a 16-amino-acid peptide encoded by mitochondrial DNA — one of a small family of “mitochondrial-derived peptides.” | NAD+ (nicotinamide adenine dinucleotide) is not a peptide but a coenzyme present in every living cell. |
| How it works | Research indicates it can move to the cell nucleus under stress and influence genes involved in metabolism, partly through the AMPK energy-sensing pathway. | It carries electrons in the reactions that turn nutrients into energy and is required by enzymes such as sirtuins and PARPs that are involved in DNA repair. |
