NAD+ decline is one of the hallmarks of aging. Can restoring NAD+ levels with supplements actually slow down the aging process? Here’s what the science says. The NAD+ Aging Connection NAD+ levels decline dramatically with age: Age Relative NAD+ Level 20-30 100% (baseline) 40 ~50% 50 ~40% 60+ ~20-30% This decline contributes to many age-related problems: Reduced cellular energy — Cells can’t produce enough ATP Impaired DNA repair — More mutations accumulate Mitochondrial dysfunction — Powerhouses of cells decline Increased inflammation — Chronic low-grade inflammation (inflammaging) Sirtuin inactivation — Longevity genes become less active How NAD+ Affects Aging 1. Sirtuins (Longevity Genes) Sirtuins are a family of proteins that require NAD+ to function. They regulate: ...

NAD+ plays a critical role in brain health. Here’s how it supports cognitive function and may protect against neurodegeneration. NAD+’s Role in the Brain 1. Energy Production The brain consumes 20% of the body’s energy despite being only 2% of body weight. NAD+ is essential for: Neuronal energy production Synaptic transmission Brain cell maintenance 2. DNA Repair Neurons are particularly vulnerable to DNA damage. NAD+-dependent enzymes (PARPs) repair this damage, preventing: ...

NAD+ plays a central role in metabolism. Here’s how it affects weight management and energy levels. NAD+’s Role in Metabolism 1. Energy Production NAD+ is essential for converting food into cellular energy (ATP): Glycolysis (sugar → energy) Beta-oxidation (fat → energy) Krebs cycle (complete energy extraction) Electron transport chain (maximum ATP production) Without adequate NAD+, these processes slow down, leading to fatigue and weight gain. 2. Fat Metabolism NAD+-dependent enzymes (sirtuins) regulate fat metabolism: ...
