What the mRNA Actually Shows
You're taking NMN or NR to support cellular NAD+ pools. But how does that metabolic support translate into downstream biological resilience? The Inflammation Compass™ measures whole-blood gene expression across 3 Health Domains — revealing how NAD+ optimization and metabolic longevity interventions interface with systemic inflammatory calming, oxidative balance, and active cellular resilience.
Why NAD+ Matters
Nicotinamide adenine dinucleotide is a coenzyme present in every living cell — and its decline may be one of the most consequential molecular events of aging.
The Cellular Engine
NAD+ is a critical coenzyme in every cell of your body. It's essential for energy production (mitochondrial electron transport), DNA repair (PARP activation), sirtuin activation (the master longevity regulators), and circadian rhythm regulation. Without adequate NAD+, these processes slow — and aging accelerates.
The Decline
NAD+ levels decline approximately 50% between ages 40 and 60. This isn't subtle — it's a halving of a molecule required for hundreds of enzymatic reactions. The decline is driven by increasing CD38 expression, accumulated DNA damage (consuming NAD+ via PARP), and decreased NAMPT activity in the salvage pathway.
The Supplementation Response
Millions of people now take NMN (nicotinamide mononucleotide) or NR (nicotinamide riboside) — NAD+ precursors designed to restore declining levels. Both are available as over-the-counter supplements. Both raise NAD+ levels in studies. But raising a level is not the same as activating a pathway.
The Real Question
Is your supplementation strategy translating into downstream cellular resilience? Are systemic inflammatory cascades calming? Is active resolution machinery engaging? These aren't questions a simple blood NAD+ level can answer. The Inflammation Compass™ provides the objective transcriptomic clarity across the 3 Health Domains to track your systemic biological response.
The Precursor Debate,
Resolved by Data
Both NMN and NR are NAD+ precursors. Both raise NAD+ levels in studies. But the real question isn't whether NAD+ goes up — it's what happens downstream.
NMN Pathway
Nicotinamide Mononucleotide — converted directly to NAD+ via NMNAT enzymes (NMNAT1, NMNAT2, NMNAT3). A larger molecule with ongoing debate about oral bioavailability. Some researchers suggest sublingual delivery may improve absorption.
Systemic Context
In preclinical research, NMNAT enzymes convert NMN to NAD+, fueling downstream sirtuin activity and mitochondrial dynamics. In circulating blood, the systemic reflection of this metabolic support is observed through inflammatory calming and enhanced resolution capacity.
NR Pathway
Nicotinamide Riboside — converted to NMN via NRK1/NRK2 enzymes (nicotinamide riboside kinases), then to NAD+. A smaller molecule with more human clinical data. Bioavailability depends on NRK enzyme expression in target tissues.
Systemic Context
NR relies on NRK kinases before conversion to NAD+. Rather than measuring precursor enzymes directly in target tissues, systemic transcriptomics tracks whether the overall intervention promotes cellular resilience and quiets systemic inflammatory stress.
The Data-Driven Answer
The answer isn't which precursor is "better" in general — it's which one translates into downstream biological resilience in YOUR body. Does NMN promote more systemic inflammatory calming for you? Does NR support stronger resolution capacity? Whole-blood transcriptomic profiling provides the objective baseline and longitudinal data across the 3 Health Domains to evaluate your body's systemic response.
Core NAD+ Mechanisms in the Literature
NAD+ biology interfaces deeply with cellular defense, mitochondrial integrity, and longevity programs. While published studies examine these specific molecular pathways, the Inflammation Compass™ evaluates overall systemic inflammatory calming, oxidative balance, and active resolution capacity in whole blood across the 3 Health Domains.
Sirtuin & Epigenetic Regulation
SIRT1 · SIRT3 · SIRT6 · SIRT1-7 Family
Biological role: Sirtuins are NAD+-dependent deacetylases that regulate cellular defense, metabolic homeostasis, and DNA repair. SIRT1 directly deacetylates the p65 subunit of NF-κB, suppressing chronic inflammatory transcription.
Systemic connection: When intracellular NAD+ pools are replete, active sirtuin signaling helps quell chronic myeloid activation, an effect reflected in lower Activation domain scores in whole blood.
NAD+ Salvage & Recycling
NAMPT · Rate-Limiting Salvage
Biological role: NAMPT converts nicotinamide back into NMN, serving as the master rate-limiting gatekeeper of cellular NAD+ recycling. Declining NAMPT expression is a key molecular hallmark of metabolic aging.
Systemic connection: Immune cells require substantial metabolic energy to execute stand-down and tissue clearance. Robust salvage recycling supports the high bioenergetic demand of active Resolution pathways.
Inflammatory NAD+ Consumption
CD38 · Ectoenzyme · Immune Consumer
Biological role: CD38 is an ectoenzyme predominantly expressed on activated immune cells (macrophages, monocytes, lymphocytes) that degrades NAD+ into nicotinamide and cADPR, accelerating with age and chronic inflammatory stress.
Systemic connection: Chronic innate immune activation drives high CD38 expression, depleting systemic NAD+ reserves. Calming the Activation domain helps relieve this ongoing metabolic drain.
Genomic Stress & PARP Demands
PARP · DNA Damage Response
Biological role: PARP enzymes consume NAD+ to synthesize poly(ADP-ribose) polymers during genomic single- and double-strand break repair. Excessive DNA damage rapidly exhausts cellular NAD+ pools.
Systemic connection: Persistent genomic damage triggers innate immune danger sensors (such as cGAS-STING), bridging unresolved cellular stress to elevated whole-blood inflammatory tone.
Mitochondrial Homeostasis
PGC-1α · TFAM · Mitochondrial Dynamics
Biological role: PGC-1α and TFAM coordinate mitochondrial DNA replication and organelle biogenesis, maintaining cellular respiration and oxidative phosphorylation.
Systemic connection: Intact mitochondrial dynamics prevent the leakage of mitochondrial reactive oxygen species (mtROS) and mtDNA into the cytoplasm, avoiding sterile inflammatory triggers in circulating leukocytes.
Stress Resistance & Clearance
FOXO · Autophagic Stand-Down
Biological role: FOXO transcription factors coordinate antioxidant defense, protein quality control, and autophagy — the enzymatic recycling of damaged cellular organelles and aggregated proteins.
Systemic connection: Efficient autophagic clearance directly interfaces with leukocyte resolution programs, facilitating homeostatic recovery and tissue clearance tracked in the Resolution domain.
Diagnostic Boundary: The Inflammation Compass™ is a whole-blood RNA sequencing test that measures systemic gene expression across the 3 Health Domains (Activation, Antiviral Response, and Resolution) plus cellular deconvolution. It does not provide direct isolated tissue enzyme assays for NAMPT, SIRT1-7, or CD38.
Why Blood NAD+ Levels Aren't Enough
Some companies offer NAD+ blood level tests. But knowing your circulating NAD+ coenzyme level doesn't tell you whether your cells are experiencing reduced inflammatory stress or improved resolution capacity.
Elevated NAD+, High Activation
Your blood NAD+ test says levels are elevated. But systemic inflammatory signaling remains high and resolution machinery is flat. The fuel is there, but cellular stress hasn't settled. Without transcriptomic profiling across the 3 Health Domains, you'd assume your protocol was working perfectly.
Adequate NAD+, Ongoing Drain
Your NAD+ level looks adequate — because you're supplementing. But ongoing innate immune activation continues to consume cellular resources. You're supplementing, but persistent inflammatory drain continues unnoticed without whole-blood RNA analysis.
Rising NAD+, Flat Resolution
NAD+ levels are going up, but active stand-down programs haven't engaged. Your cells have more coenzyme availability, but the active resolution machinery is stalled — the critical recovery phase that traditional blood tests miss completely.
A blood NAD+ level is one static number. The Inflammation Compass™ gives you the full systemic biological story across the 3 Health Domains.
