NAD+: sirtuins, DNA repair, and strategies to restore its levels
Nicotinamide adenine dinucleotide (NAD+) is central to hundreds of metabolic reactions. Its cellular levels decline by approximately 50% between the ages of 20 and 60, correlating with mitochondrial decline, loss of DNA repair capacity, and sirtuin depletion. Understanding the biochemistry of NAD+ is essential for evaluating restoration strategies: NMN, NR, and direct injections.

MOTS-c: the mitochondrial peptide that mimics exercise
MOTS-c (Mitochondrial Open Reading Frame of the 12S rRNA type-c) is a 16-amino-acid micropeptide encoded by mitochondrial DNA—a major 2015 discovery that revolutionized our understanding of mitochondrial signaling. It activates the AMPK pathway, enhances insulin sensitivity, and produces exercise-like effects in preclinical models.
