Why NAD⁺ biology matters to what RL100 measures.
This page explains why Ultra Pure™ NMN was chosen as the Foundation input — while the Assessment still comes first, because the system needs a baseline before any 100-day protocol can be interpreted.

NAD⁺. Why it matters to what we measure.
- 1 NAD⁺ is a coenzyme present in every cell in your body. Your cells use it for three fundamental processes: generating energy, repairing damage, and regulating the biological rhythms that govern how you sleep, recover, and function across the day.
- 2 NAD⁺ levels decline measurably with age. This is not a theory — it has been documented across multiple human cohort studies, with tissue-level measurements correlating with biological age markers and physiological reserve across organ systems. By the mid-thirties, levels in most tissues have fallen measurably from their peak.
- 3 That decline is relevant to systems many people recognize in daily life: energy that drops earlier in the afternoon, sleep that feels less restorative, mental clarity that fluctuates more than it used to, skin that recovers more slowly from daily stress, physical recovery that takes longer after exertion, and metabolic consistency that becomes harder to maintain. These are not presented as diagnoses. They are biological areas where NAD⁺ availability has been studied and where the Cellular Vitality Index™ (CVI) creates a structured self-reported baseline.
- 4 That is why measurement comes first. Without a documented baseline, a 100-day observation has no reference point. The Assessment establishes where you are. The protocol documents what occurs.
- 5 The Foundation input is Ultra Pure™ NMN — a direct NAD⁺ precursor selected because it can be held steady as the daily input in the first 100-day measurement window. NMN enters the body’s own NAD⁺ production pathway one step before NAD⁺ itself. Published human randomized controlled trials confirm NMN raises NAD⁺ levels measurably in the blood; mechanistic research describes NAD⁺ roles in mitochondrial energy production, sirtuin-mediated cellular repair pathways, and PARP enzyme activity involved in DNA repair.
- 6 The question RL100 is built around is not whether NAD⁺ matters in general. It is how your measured areas change during a standardized 100-day Ultra Pure™ NMN protocol. That is what the documented baseline is for. That is what the Outcome Report compares.

Twelve biological areas.
Each one connected to published NAD⁺ research — and each one connected to something most adults can recognize in their own daily experience.
The Cellular Vitality Index™ (CVI) does not diagnose NAD⁺ status, score your skin, or clinically evaluate your health. It documents self-reported baseline patterns across twelve biological areas where NAD⁺ biology has been studied. Each area corresponds to patterns many people notice in themselves — afternoon energy, sleep quality, mental clarity, recovery time — translated into a structured measurement frame.
Cellular Energy Expression
NAD⁺ is essential to the mitochondrial electron transport chain — declining availability reduces cellular ATP production efficiency.
Sleep Architecture
NAD⁺ regulates circadian rhythm through SIRT1-mediated control of the CLOCK/BMAL1 transcription complex.
Cognitive Steadiness
NAD⁺ availability in neural tissue supports mitochondrial energy production and neuroprotective sirtuin activity.
Metabolic Equilibrium
NAD⁺ is a required cofactor for enzymes in glycolysis and the citric acid cycle — influencing energy consistency across the day.
Physical Recovery
NAD⁺ supports mitochondrial biogenesis and PARP-mediated DNA repair in muscle cells following physical exertion.
Stress Adaptation
NAD⁺ supports circadian stability and hypothalamic NAD⁺ biosynthesis — pathways connected to stress response regulation.
Dermal Resilience
NAD⁺ supports sirtuin and PARP enzyme activity involved in skin cell repair and extracellular matrix maintenance.
Skin Luminosity & Tone
NAD⁺ supports mitochondrial energy in keratinocytes and regulates sirtuin-mediated cellular turnover in surface skin layers.
Vitality Architecture
NAD⁺ supports SIRT1-mediated regulation of steroid hormone biosynthesis — pathways connected to physical drive and hormonal equilibrium.
Cardiovascular Ease
NAD⁺ supports endothelial function through eNOS activity and SIRT1-mediated vascular biology.
Immune Resilience
NAD⁺ aids DNA repair in immune cells and provides energy for rapid immune cell proliferation and response.
Ocular Surface Comfort
Published research documents NAD⁺’s role in meibomian gland cell function, which governs tear film stability.
Each area is relevant to published NAD⁺ biology — and still requires measurement in the individual.
The research foundation.
The research supporting the twelve biological areas and the Foundation supplement draws from three tiers of evidence — each with a different relationship to what participants may observe in their own biology.
Multiple randomized controlled trials in adults have documented NAD⁺ bioavailability following oral NMN supplementation, alongside measurements of insulin sensitivity, walking endurance, and metabolic markers. Trials have been conducted across adult age ranges and dosage levels relevant to the RL100 protocol. This is the evidence tier most directly relevant to why NMN was selected as the Foundation input.
Age-related NAD⁺ decline has been documented across multiple human cohort studies. Tissue-level NAD⁺ measurements correlate with biological age markers, mitochondrial function indicators, and physiological reserve across organ systems. This research establishes the biological context — why NAD⁺ decline is a measurable phenomenon and why the twelve biological areas were selected.
Mechanistic and animal model studies establish the biological pathways through which NAD⁺ operates across the twelve measured biological areas — SIRT1-mediated regulation, PARP enzyme activity, mitochondrial biogenesis, and circadian gene expression. This layer explains the mechanisms — why the biology works the way the research suggests it does.
