The Science of Eternal
Healthy aging begins at the cellular level. Eternal NAD+ combines three purposeful activesβNAD+, Quercetin, and Resveratrolβto support the cellular processes behind energy, antioxidant defense, vitality, and healthy aging.*

Antioxidant
Quercetin Β· 250 mg
Healthy Aging
Resveratrol Β· 150 mg
Start Beneath the Surface
Every moment of your life depends on trillions of cells producing energy, responding to stress, repairing themselves, and communicating with one another.
As we age, many of these cellular processes can become less efficient. That is why modern healthy-aging research increasingly focuses on supporting the biological systems that help cells function optimally over time.[1]
Eternal NAD+ was built around that philosophy: support the foundation first.
Cells require a constant supply of energy to power everything from movement to mental performance.
Everyday metabolism creates oxidative stress. Antioxidant compounds help support the body's natural defenses against it.*
Healthy cells rely on complex pathways involved in metabolism, signaling, and cellular maintenance.
Supporting cellular wellness is one piece of maintaining energy, resilience, and vitality throughout life.*
The mitochondrion
Where much of the cell's energy metabolism takes place
The Foundation
nicotinamide adenine dinucleotide
NAD+, short for nicotinamide adenine dinucleotide, is a naturally occurring coenzyme found throughout the body.[1]
It plays an essential role in cellular metabolism and the chemical reactions cells use to produce energy.[1,2]
NAD+ also participates in pathways associated with cellular signaling, metabolic regulation, DNA maintenance, and other fundamental biological processes that researchers continue to study in connection with healthy aging.[1,3,5]
Think of NAD+ as part of the cellular machinery that helps turn nutrients into usable energy.
Scientific research has found that NAD+ availability can change with age and has generated significant interest in understanding its relationship with metabolism, cellular function, and healthy aging.[3,4,6]
What we know
NAD+ is essential to cellular metabolism, and human tissue studies have reported age-associated changes in NAD+ metabolism.
Still being studied
Much of the research linking NAD+ to aging comes from cell and animal models. How those findings apply to people is still being established.
Three Purposeful Actives
Instead of overcrowding the label with dozens of ingredients, Eternal NAD+ focuses on three complementary compounds selected to support cellular energy, antioxidant defense, and healthy-aging wellness.*
01
Cellular Energy
Nicotinamide adenine dinucleotide
NAD+ is a naturally occurring coenzyme involved in essential metabolic reactions throughout the body.[1]
It plays a central role in cellular energy metabolism and also serves as a substrate for enzymes involved in important cellular processes.[2,5]
With 500 mg per serving, NAD+ forms the foundation of the Eternal formula.*
02
Antioxidant Defense
Sophora japonica flower bud
Quercetin is a naturally occurring plant flavonoid found in many fruits and vegetables.[7]
It has been extensively studied for its antioxidant properties and its interaction with cellular pathways associated with oxidative stress and overall cellular wellness.*[7,8]
Our Quercetin is derived from Sophora japonica flower buds.
03
Healthy Aging
Japanese Knotweed Extract β’ 98% Resveratrol
Resveratrol is a naturally occurring polyphenol found in several plants and has become one of the most widely researched compounds in the healthy-aging space.[10]
Research has explored its antioxidant activity and interaction with pathways involved in cellular stress response and metabolic health.*[10,11,12]
Eternal uses Japanese Knotweed Extract standardized to 98% Resveratrol.
A Complementary Approach
NAD+
Supports cellular energy and metabolic processes.*
Quercetin
Provides plant-based antioxidant support.*
Resveratrol
Provides complementary antioxidant and healthy-aging support.*
Eternal NAD+ brings these three ingredients together in a focused formula designed to support cellular wellness from multiple anglesβwithout an overloaded ingredient list.*
The research referenced on this page concerns the individual ingredients, not the finished Eternal NAD+ formula.
Why It Matters
Energy
Supporting cellular energy can help provide the biological foundation behind the active, full life you want to keep living.*
Clarity
The brain is highly energy-dependent. Supporting cellular wellness is part of supporting overall cognitive health and mental performance as you age.*
Resilience
Quercetin and Resveratrol provide antioxidant support designed to complement the body's natural cellular defenses.*
Healthy Aging
Healthy aging is not one pathway, ingredient, or quick fix. It is the result of consistently supporting the systems your body relies on throughout life.*
Because aging well isn't about chasing youth. It's about protecting the energy, confidence, and vitality that make you feel like yourself.

Everyday Vitality
The human body is extraordinarily complex. No supplement controls the aging process. Eternal NAD+ is designed to support key aspects of cellular wellness as one part of a healthy lifestyle that includes nutritious food, movement, quality sleep, hydration, and preventive healthcare.*
Peer-Reviewed Research
NAD+ is an essential coenzyme involved in cellular metabolism, redox reactions, and energy production. Research has also examined NAD+-dependent pathways in relation to cellular maintenance and aging biology.
Evidence note: NAD+'s role in metabolism is foundational biology. Much of the research on NAD+ and aging comes from cell and animal models; human research is ongoing.
Quercetin is a plant-derived flavonoid studied extensively for antioxidant activity, oxidative stress, inflammatory pathways, and other aspects of cellular health.
Evidence note: Findings differ by population, formulation, dose, and endpointβand many laboratory findings have not been confirmed in human trials.
Resveratrol is a plant polyphenol researched for its antioxidant activity and its interactions with cellular signaling and stress-response pathways.
Evidence note: Human trial outcomes vary, and mechanistic findings from cell and animal research do not necessarily translate into meaningful clinical outcomes.
Our Approach
Healthy-aging science is evolving quickly. We believe you deserve to know the difference between what biology tells us, what early research suggests, and what human clinical research has actually demonstrated.
That's why Eternal Nutrients focuses on purposeful ingredients, transparent amounts, responsible claims, and continued attention to emerging research.
No mystery around what you're taking.
Every active has a reason for being here.
Formulated around compounds actively studied in cellular and healthy-aging research.
Healthy aging is a long-term investment, not an overnight transformation.

Science FAQ
Clear answers about what the science saysβand what it doesn't.
NAD+ is a coenzyme required for numerous cellular reactions, including reactions involved in turning nutrients into usable cellular energy. It is also used by several families of enzymes involved in cellular signaling and maintenance.[1,2]
Research has reported age-associated changes in NAD+ metabolism and NAD+ availability, although the magnitude and consistency of those changes in humans can vary between tissues and studies.[3,4]
Quercetin and Resveratrol provide complementary antioxidant support and have each been studied for their interactions with cellular stress-response pathways.*[7,10]
No supplement can reverse the aging process. Eternal NAD+ is designed to support cellular energy, antioxidant defense, wellness, and healthy aging as part of a consistent healthy lifestyle.*
The research referenced on this page concerns the individual ingredientsβNAD+, Quercetin, and Resveratrolβnot the finished Eternal NAD+ formula. Each ingredient is supported by a different level and type of scientific research, from foundational biology to human clinical trials. We developed the formula based on the biological roles of these compounds and the research surrounding them, and we're careful not to claim more than that evidence supports.
Take 2 capsules daily with water as part of a consistent wellness routine. If you are pregnant, nursing, taking medication, or have a medical condition, consult your healthcare provider before use.
