You can't live without NAD+.

The bad news: NAD+ levels are destroyed by aging, inflammation, diet, stress, and sickness. This leads to weakness, frailty, and even faster aging.


The good news: You can help restore your NAD+ levels with exercise, nutrition, and targeted supplement formulas.

NAD+ precursor response is personal.

The enzymes that rebuild your NAD+ stores vary by person and tissue, so the same supplement doesn’t always produce the same effect.


Supporting multiple pathways with NMN, NR, and Trigonelline helps you get reliable, steady NAD+ support without guesswork.

NAD+ boosters like NMN and NR are only the beginning.

After years of analyzing the research, we've aligned with a systems-level approach to address four main pathways to support healthy NAD+ levels throughout the entire body. This systems-level approach is described elegantly by Nichola Conlon and Dianne Ford in a recent study on NAD+ restoration.

Every Renue By Science formula helps you maximize NAD+ through one of these pathways.

Boost

Protect

Optimize

Regenerate

Why all four pathways matter.

Each pathway addresses a different bottleneck in NAD+ metabolism, and they work synergistically:

  • BOOST providesNAD+precursors through multiple biosynthetic routes: salvage, Preiss-Handler, and NR kinase pathways. This increases substrate availability forNAD+production.

  • PROTECT inhibits CD38 and reduces inflammation-drivenNAD+consumption. CD38 activity can consume 100x moreNAD+than other enzymes, so blocking it preserves yourNAD+pool.

    • BOOST providesNAD+precursors through multiple biosynthetic routes: salvage, Preiss-Handler, and NR kinase pathways. This increases substrate availability forNAD+production.

    • PROTECT inhibits CD38 and reduces inflammation-drivenNAD+consumption. CD38 activity can consume 100x moreNAD+than other enzymes, so blocking it preserves yourNAD+pool.

    • OPTIMIZE improves mitochondrial efficiency through SIRT1 activation and AMPK signaling. More efficient mitochondria require lessNAD+to produce the same amount of ATP.

    • REGENERATE activates autophagy and cellular cleanup during sleep, reducing the accumulated damage that createsNAD+demand for repairs.

      • OPTIMIZE improves mitochondrial efficiency through SIRT1 activation and AMPK signaling. More efficient mitochondria require lessNAD+to produce the same amount of ATP.

      • REGENERATE activates autophagy and cellular cleanup during sleep, reducing the accumulated damage that createsNAD+demand for repairs.

        When combined, these pathways create a positive feedback loop:

        Multiple precursors prevent pathway saturation.

        CD38 inhibition preserves what you produce.

        Efficient mitochondria reduce NAD+ consumption.

        Overnight cleanup minimizes repair demands.

        The result:NAD+levels rise and stabilize rather than experiencing the typical single-supplement plateau. Research shows multi-pathway interventions achieve better outcomes than single precursor supplementation alone.

        Making It Real.

        Understanding the four pathways changes how you think about energy and aging. You now see why that afternoon crash happens, why recovery takes longer than it used to, and why some supplements work initially then fade.

        More importantly, you understand there's a systematic way forward.

        Some people start with just one pathway, usually BOOST for quick energy improvements or PROTECT if they're already taking supplements that seem less effective than before. Others prefer addressing multiple pathways together for synergistic benefits.

        What most people find: Starting somewhere, even imperfectly, teaches you what your body responds to. The first positive change usually happens within the first two weeks. That initial improvement often clarifies what to adjust next.

        The research provides the map. Your experience becomes the compass.

          How NMN supports NAD+

          Supplemental NMN supplies a direct building block for the body's NAD+salvage pathway.


          Absorption & use: NMN is absorbed and utilized to help sustain healthy, youthful NAD+ production.


          Conversion: Inside cells, enzymes (including NMNAT) convert NMN into NAD+.

          Cellular support: By supporting NAD+ availabilty, NMN helps power energy metabolism and NAD-dependent housekeeping pathways (PARPs, sirtuins).

        Supports Energy Metabolism

        NAD+participates in the reactions that turn food into ATP inside mitochondria. It also supports the electron transport chain, which fuels nearly every cellular unction.

        Supports Brain-Health Cellular Pathways

        NAD+is consumed by PARP enzymes involved in the cellular response to everyday DNA stressors. Sustaining NAD+helps ensure these maintenance pathways have the coenzyme they need.

        Supports DNA Maintenance & Cellular Health

        Sirtuins rely on NAD+to influence cellular house keeping,metabolic signaling, and chromatin regulation-factors tied to how cells adapt to stress and maintain efficiency.

        Supports Vascular & Endothelial Function

        NAD+availability supports pathways that help mitochondria produce energy efficiently and manage oxidative workload.

        Supports Metabolic Flexibility

        Sustaining healthy NAD+helps the cellular machinery that coordinates how we use and switch among fuel sources from food.

        PURE CRYSTALLINE NMN

        Our NMN Powder is 100% pure crystalline Nicotinamide Mononucleotide, designed for absorption under the tongue for superior bioavailability compared to regular capsules.

        Why NMN is helpful for healthy aging.

        Aging involves cumulative cellular work: oxidative load, DNA maintenonce, and changing infiammatory tone, all of which increase demand for NAD+. When supply lags behind demand, cells may struggle to keep pace. Damage can accumulate and cells may struggle between repair and normal daily functions.

        Bridging the NAD+ gap with NMN.

        LowerNAD+availability can contribute to sluggish energy,slower bounce-back after activity, and less adaptable metabolism.

        Adding NMN supplies precursor material your cells can use to sustainNAD+, helping to:

        ● Re-energize mitochondrial pathways for day-to-day vitality.

        ● Support DNA maintenance work flows that rely on NAD+.

        ● Activate NAD+-dependent housekeeping linked to healthy aging.

        ● Support overall immune readiness within normal,healthy reactions.

        ● Encourage metabolic flexibility as part of a balanced routine.

        Is it just aging, or are your NAD+ pathways slowing down?

        When one pathway stalls, your energy suffers.

        NAD+ is essential for energy, repair, and resilience. As we age, NAD+ synthesis pathways slow down, leading to a dramatic drop in cellular energy. By age 50, we have half of what we did when we were younger. Factors like poor diet, sedentary lifestyles, illness, and environmental toxins deplete NAD+ even faster.

        Our scientifically designed multi-pathway formulas restore NAD+ where your biology needs it most.
