NAD (nicotinamide adenine dinucleotide) is a vital coenzyme necessary for energy production, DNA repair, and cell survival. Its active form, NAD+, has garnered attention for its potential to slow aging and enhance brain health, especially as its levels decline with age. Celebrity interest has surged, leading to an increase in NAD+ tests and supplements. Experts emphasize that NAD is crucial for activating enzymes that repair DNA and impact inflammation, making it a fundamental component of cellular function and health.
"It's vital for activating enzymes called sirtuins and PARPs - classes of enzymes involved in DNA repair, longevity and inflammation," Daniel Puleston explained.
"If you don't have enough NAD, your mitochondria don't function efficiently," said longevity biomarker scientist Jin-Xiong She.
