    How NAD+ works

    NAD+ is a coenzyme your cells use to turn nutrients into usable energy — and its levels fall as you age.

    NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every living cell. It works as an electron carrier in redox reactions across glycolysis, the citric acid cycle, and oxidative phosphorylation. In the mitochondria, it supports ATP synthesis — the process that converts nutrients into the energy your cells actually run on.

    NAD+ is also a cofactor for enzymes involved in cellular maintenance and repair, including pathways tied to DNA and nervous system function. It is not a stimulant. It does not add energy from outside the body — it supports the machinery that produces energy from within.

    NAD+ levels decline measurably with age. That decline has been studied for its contribution to age-related cellular changes — slower energy metabolism and reduced cellular resilience. An NAD+ protocol is aimed at supporting the availability of the coenzyme, not overriding the body's chemistry.

    Why NAD+

    NAD+ protocols sit in a clinical gap: more serious than the NMN and NR precursor supplements on the shelf, more accessible than a several-hundred-dollar IV drip at a longevity clinic, and more specific than a general energy complaint a standard care visit isn't built to address.

    Most men in their 40s and 50s encounter NAD+ through podcasts and longevity research long before they find a physician who prescribes it. EdgeRx closes that gap — the same compound, a US-licensed 503A compounding pharmacy, US board-certified physician review.

    What to expect

    NAD+ is not a stimulant — there is no acute hit and no crash. Most men describe the change as a gradual lift in baseline energy and mental clarity that builds over the first several weeks of consistent daily use.

    • Steadier daytime energy — without a stimulant peak and crash
    • Clearer thinking and less mental fatigue
    • Better tolerance of demanding mental and physical days
    • Support for the cellular processes tied to healthy aging

    What NAD+ supports

    Cellular energy production

    NAD+ may function as an electron carrier in the mitochondrial electron transport chain, supporting ATP synthesis — the conversion of nutrients into cellular energy. Adequate NAD+ availability is associated with efficient energy metabolism.

    Metabolic function

    NAD+ may serve as a cofactor for enzymes involved in mitochondrial metabolic pathways. Sufficient NAD+ availability is believed to support energy production and the maintenance of essential cellular components.

    Nervous system support

    NAD+ has been studied for its role in neuronal health, including involvement in DNA-supporting pathways. Some research suggests that supporting NAD+ levels may be associated with healthy nervous system and brain function.

    Healthy cellular aging

    NAD+ levels decline with age, and that decline has been studied for its contribution to age-related cellular changes. Some research suggests that supporting NAD+ levels may help maintain healthy cellular aging processes.

    How you take it

    The routine

    One or two sprays in each nostril, once or twice daily, as your physician directs. Your physician sets your exact dose and frequency based on your history. No injection, no reconstitution, no clinic visit.

    Starting dose

    Your physician will set your starting dose based on your history. The nasal spray is formulated at 300 mg/mL; titration happens through spray count and daily frequency rather than per-spray changes. Most men start at the lower end of the range and adjust at a check-in if needed.

    Storage

    Store upright in the refrigerator. 35-day shelf life once opened. Each bottle is approximately one month of dosing.

    Schedule

    NAD+ protocols are typically run continuously as ongoing cellular and energy support, rather than in cycles. Your physician will recommend the schedule that fits your goals and review it at your check-ins.

    Questions

    No. NMN and NR are NAD+ precursors — supplement-grade compounds your body must first convert into NAD+, sold over the counter without a prescription or physician oversight. EdgeRx's protocol uses NAD+ itself, compounded by a US-licensed pharmacy and prescribed by a board-certified physician. Same target, different category: a prescription protocol rather than a shelf supplement.

    NAD+ is available through 503A compounding pharmacies in the US, where it is prepared under FDA-regulated quality standards by US-licensed pharmacies. Compounded medications are not reviewed or approved by the FDA as finished products.

    NAD+ IV therapy delivers the compound directly into the bloodstream during a clinic visit that can run one to several hours and cost several hundred dollars per session. The nasal spray uses intranasal absorption — the compound crosses nasal tissue with no needle and no clinic visit. Bioavailability per dose is lower than an IV, but the nasal spray is built for consistent daily use at home, which is what sustained NAD+ support actually depends on. For most men, regular daily dosing matters more than the peak a single IV produces.

    Both are non-injectable NAD+ formats taken at home — no needle, no clinic visit. The nasal spray is the simpler routine: one or two sprays, with a 35-day shelf life. The sublingual tablet is a flex-dose format — your physician can fine-tune the dose by the fraction of a tablet — and it has a 180-day shelf life, which can mean fewer reorders. Either is a reasonable starting format; your physician can help you choose based on your routine and how precise you want the dose.

    Yes. NAD+ pairs well with the other protocols in the Energy, Longevity & Cognition category and across the catalog — many men run it alongside a recovery or metabolic protocol. The protocol your physician builds accounts for everything else you are taking, so disclose your full medication list during the medical assessment.

    NAD+ is well tolerated by most men. Possible side effects include headache, nausea, and mild dizziness. Because the nasal spray is absorbed through nasal tissue, some men also notice brief nasal irritation. Effects are typically mild and transient.

    NAD+ is not appropriate for everyone. Because NAD+ is involved in cellular energy metabolism, its use in men with a history of or susceptibility to cancer should be carefully evaluated by a physician. NAD+ is also not appropriate during pregnancy or breastfeeding. Your physician screens for these during the medical assessment, along with any interactions with your current medications.

    NAD+ is not a stimulant, so there is no immediate hit the way caffeine produces one. Most men describe a gradual lift in baseline energy and mental clarity over the first few weeks of consistent daily use. The value is in sustained use, not a single dose.
