are peptides natural

Peptide NAD, or nicotinamide adenine dinucleotide peptide, is a crucial coenzyme essential for cellular metabolism, participating in oxidative phosphorylation within mitochondria. It aids in electron transport, converting nutrients to energy, and is involved in numerous processes, including DNA repair and gene expression. Its potential for therapeutic applications in aging and neurodegenerative diseases has prompted extensive research, despite challenges in understanding its synthesis and ensuring effective supplementation.
