NAD Plus, or nicotinamide adenine dinucleotide, is the cell's most versatile coenzyme. It sits at the heart of metabolism, DNA repair, and the signaling pathways that govern longevity. When you think of cellular aging, NAD Plus is the linchpin that keeps your cells running smoothly.
In the mitochondria, NAD Plus shuttles electrons from glycolysis and the Krebs cycle into oxidative phosphorylation. Each round of this electron transport chain produces ATP, the energy currency of the cell. Without adequate NAD Plus, ATP production slows, and cells feel the fatigue that accompanies aging.
Beyond energy, NAD Plus is the fuel for poly(ADP‑ribose) polymerases, the enzymes that detect and repair DNA breaks. As DNA accumulates damage, the demand for NAD Plus rises. A steady supply keeps the repair machinery humming, preserving genomic integrity and slowing the clock on cellular aging.
NAD Plus also activates sirtuins, a family of deacetylases that regulate mitochondrial biogenesis, inflammation, and circadian rhythms. Sirtuin activation promotes efficient energy use and resilience to stress, creating a feedback loop that supports healthy aging.
Unfortunately, NAD Plus levels naturally decline with age. Chronic inflammation, oxidative stress, and increased activity of CD38 and PARPs consume the coenzyme faster than it can be regenerated. The result is a drop in energy production, DNA repair capacity, and sirtuin activity—key drivers of the aging process.
Functional medicine offers practical ways to boost NAD Plus. A diet rich in tryptophan, niacin, and nicotinamide riboside—found in leafy greens, legumes, and fortified foods—provides the building blocks. Intermittent fasting, regular aerobic exercise, and reducing alcohol and high‑glycemic foods further support NAD Plus synthesis. Supplements such as nicotinamide riboside (NR) or nicotinamide mononucleotide (NMN) are popular choices for those who want a direct boost.
By combining dietary choices, lifestyle habits, and targeted supplementation, you can maintain healthy NAD Plus levels, enhance energy production, DNA repair, and sirtuin activation, and ultimately slow cellular aging. Think of NAD Plus as the power plant of your cells—keeping it running optimally is a cornerstone of functional medicine for longevity.
