How To Boost NAD Levels To Fight Inflammation, Improve Recovery, and Slow Aging
Dr. Charles Brenner, discoverer of nicotinamide riboside (NR), explains NAD's critical roles in energy production, DNA repair, and inflammation. Clinical trials show NR supplementation significantly reduces inflammation markers and may benefit exercise recovery, peripheral artery disease, and age-related conditions.
Summary
This comprehensive discussion covers NAD biology and supplementation with Dr. Charles Brenner, who discovered nicotinamide riboside (NR). NAD functions as the cellular "wiring" for high-energy electrons, enabling energy production, biosynthesis, and repair processes. Brenner explains that NAD operates in four forms (NAD+, NADH, NADP+, NADPH) to facilitate fuel conversion, building cellular components, and repair mechanisms. While blood NAD levels don't necessarily decline with age, tissue NAD becomes depleted through inflammatory processes, disease states like obesity and metabolic syndrome, sleep disruption, and chronic stress. Eight randomized clinical trials demonstrate NR's anti-inflammatory effects, with participants showing significantly reduced inflammatory markers (IL-6, IL-10). The supplement shows promise for peripheral artery disease, with patients improving six-minute walk tests while placebo groups declined. Exercise naturally upregulates NAD biosynthetic enzymes, and NR appears to enhance workout recovery, leading professional sports teams like the New England Patriots to use it. Brenner clarifies why direct NAD supplementation doesn't work (phosphate groups prevent cellular uptake), while NR effectively enters cells and converts to NAD. Safety data from clinical trials up to 3 grams daily appears favorable, with Australian studies showing nicotinamide actually reduces skin cancer risk. The optimal dosing appears to be 500-1000mg daily, particularly beneficial for those with inflammatory conditions, intense exercise regimens, or metabolic stress.
Key Insights
- NAD levels in blood don't necessarily decline with age in healthy people, but tissue NAD pools become disturbed in aging and disease conditions
- Corona virus infection activates five different PARP family members that consume NAD, representing a common inflammatory response to various pathogens
- Eight randomized clinical trials have proven nicotinamide riboside is anti-inflammatory in humans, significantly lowering IL-6, IL-10 and other inflammatory markers
- The anti-inflammatory effects of NR were so strong that people who took NR first followed by placebo still had lower inflammation after 3 weeks on placebo
- Direct NAD supplementation doesn't work because compounds with phosphates cannot enter cells, requiring breakdown to smaller precursors like NR first
- Professional sports teams including the New England Patriots have used Niagen for years based on anecdotal evidence for exercise recovery benefits
- A clinical trial showed NR improved six-minute walk tests in peripheral artery disease patients while placebo and NR plus resveratrol groups both declined
- Pregnant mice supplemented with NR produced more milk and had offspring with better lean mass, physical development, and reduced anxiety throughout their lives
- Australian clinical trials demonstrated that nicotinamide supplementation actually lowers skin cancer risk at the population level, contradicting cancer concerns
- Exercise naturally increases gene expression of NAD biosynthetic enzymes, creating a synergistic effect when combined with NR supplementation
- High-fat diet and type 2 diabetes in mice disturbed the liver NAD system and degraded their ability to detoxify reactive oxygen species
- The gut microbiome plays a role in human conversion of NAD precursors and is beneficially altered by NR supplementation according to recent research
