NAD+ Nasal Spray

At a glance

• NAD+ is a coenzyme found in every living cell, central to converting the food you eat into the energy your cells run on
• Levels are lower in many older adults and under metabolic stress, which is the rationale for restoring them directly
• Delivered as a nasal spray: no needles, no mixing, no sharps to dispose of
• One 10 mL bottle contains 1,500 mg of NAD+ at 15 mg per spray, roughly 100 sprays
• Honest evidence status: the cell biology is Nobel-grade science; large human outcome trials are still early, and intranasal absorption specifically has not been quantified in published human studies. We say so rather than quote a number we cannot stand behind
• Prescribed by a US-licensed physician, with medical supervision included for the length of your treatment

What it is

NAD+ (nicotinamide adenine dinucleotide) is not a drug in the usual sense. It is a molecule your body already makes and cannot live without: a coenzyme present in every cell, required for turning food into cellular energy, repairing DNA, and running the sirtuins, a family of proteins closely studied in aging research. Your NAD+ supply is not fixed. It is consumed continuously by these processes, and research has found lower levels in many older adults and in states of metabolic stress. This is the same molecule as our NAD+ injection, in the same compounded pharmaceutical grade, formulated for delivery through the nasal lining instead of under the skin.

How it works

Every demanding thing your body does, from a hard workout to an immune response to repairing damaged DNA, spends NAD+. The theory behind restoration is simple: keep the cellular energy currency topped up so the machinery that depends on it, mitochondria, repair enzymes, sirtuins, keeps running at full capacity. NAD+ taken as a pill is largely broken down in digestion before it reaches your blood, which is why routes that bypass the gut exist. The nasal lining is thin, densely supplied with blood vessels, and absorbs directly into circulation. It is the lowest-friction way to take NAD+ daily: one spray, a few seconds, no needle. Users most commonly pursue it for energy, mental clarity, and recovery.

What the research shows

We will give you the honest picture, because NAD+ is a field where marketing runs far ahead of data. The foundational science is exceptional: NAD+'s role in cellular energy and DNA repair is textbook biochemistry, and the aging biology around it is an active, serious research field. The human clinical evidence, however, is still early. Reviews of NAD+ restoration have concluded that while preclinical studies are promising, human trials have so far shown limited proven efficacy on hard health outcomes. Two further points specific to this product. First, what is documented for NAD+ generally is that supplementation can raise blood levels and that treatment is well tolerated; what is not proven is that raising levels produces measurable improvements in energy, aging, or disease in healthy adults. Second, the nasal route itself has not been measured against injection in a published human absorption study. You will see competitors advertise precise nasal bioavailability percentages. Those numbers do not come from human trials of this molecule, and we will not repeat them. Many of our patients report feeling sharper and more energetic; we report that as experience, not as trial evidence.

What to expect

NAD+ therapy is typically used in ongoing cycles rather than as a one-time fix. Patients who respond usually describe changes in energy, focus, and recovery within the first weeks. Effects are individual, and because the outcome evidence is early, we encourage you to treat your own response as the test: if you do not notice a difference that matters to you, this may not be your tool, and your physician will say so rather than talk you into continuing. Your physician sets your spray protocol during review. After checkout, a licensed physician reviews your intake before anything ships.

Side effects and who it's not for

NAD+ is generally well tolerated. With the nasal route, the common complaints are local and short-lived: mild burning or stinging on application, a runny nose, sneezing, or a brief taste at the back of the throat. These usually settle within the first days of use. If you have an active sinus infection, significant nasal congestion, or recent nasal surgery, tell your physician, because absorption will be unreliable and the spray may be uncomfortable. Because long-term human data are limited, we do not recommend NAD+ during pregnancy or with active cancer. Your physician screens for this during review.
