What is NAD+ and why do levels matter?
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell. It plays a central role in energy metabolism, DNA repair, and cellular stress response. NAD+ levels naturally decline with age, which is why a guided protocol focuses on replenishing them.
How is NAD+ different from a daily supplement?
Oral supplements have to survive digestion before they reach your cells. A compounded injection delivers NAD+ more directly, which is why many people choose it. Your provider will help you decide if it is a fit and what dose makes sense.

How NAD+ works in the body
One molecule, three jobs: powering your cells, protecting your DNA, and supporting your brain.
Powers cellular energy
NAD+ plays a key role in mitochondrial function. As NADH, it carries the electrons that the electron transport chain uses to make ATP, your cells' usable energy.

Real people, real outcomes.
No more afternoon crashes. The energy is steady through the day and the home injection turned out to be far easier than I expected.
My focus on long workdays is noticeably clearer. Setup was simple and a US-licensed provider checked in to adjust my dose.
Recovery after training feels quicker and I sleep better. The team actually answers questions the same day.
Three weeks in and the brain fog I had blamed on age is lifting. A small daily difference that really adds up.
I travel constantly and the faster jet-lag recovery has been the surprise win. Energy stays even.
My skin looks brighter and I feel less wiped after long shifts. The check-ins kept me consistent.
I was nervous about injecting at home. The guidance made it a two-minute routine I do not think about now.
My workouts feel like they did in my early thirties. Recovery is the biggest change for me.
Steady energy without the coffee rollercoaster. I notice it most in the late afternoon.
The provider adjusted my dose when I mentioned headaches and it sorted itself out. I felt genuinely cared for.
I cancelled my old supplement stack. This is simpler and I actually feel the difference.
Sharper in meetings, calmer in the evenings. I did not expect the sleep to improve too.

Questions, answered.
Does the longevity plan require insurance?
No. NAD+ is cash-pay with no insurance needed. We accept HSA and FSA cards, all major credit and debit cards, and Klarna if you prefer to split payments. You pay $0 at checkout and are only billed after a US-licensed provider approves your plan.
Can NAD+ help prevent Alzheimer's disease?
Research here is genuinely promising but still early. Laboratory and animal studies have shown that NAD+ supports DNA repair and healthy brain-cell metabolism, and in some animal models NAD+ supplementation improved memory-related and DNA-damage markers tied to Alzheimer's. That is encouraging, but it has not been proven in people. To be clear, NAD+ is not a treatment for, or a guaranteed way to prevent, Alzheimer's or any disease. If you have specific cognitive or neurological concerns, please talk with your own physician.
What NAD+ dosing is right for me?
NAD+ injections are available as 500mg and 1,000mg vials, plus a 4,500mg nasal spray if you prefer needle-free. Your US-licensed provider reviews your intake, chooses the right starting dose for you, and adjusts it over time based on how you respond. NAD+ should only be used under provider guidance, and you can message your care team anytime to fine-tune it.
How does NAD+ work?
NAD+ is a coenzyme in every cell. It shuttles the electrons your mitochondria use to turn nutrients into ATP (energy), and it fuels sirtuins, the enzymes involved in DNA repair and healthy aging. NAD+ levels fall as we get older, which is why a guided protocol focuses on replenishing them.
Do US-licensed providers oversee my treatment plan?
Yes. A US-licensed provider, never a chatbot, reviews your intake, prescribes if appropriate, and adjusts your dose over time. You can message your care team anytime at no extra cost.
Does KairoRx use FDA-regulated pharmacies?
Yes. Your NAD+ is sourced through FDA-registered, US-based compounding pharmacies that follow strict regulatory and safety guidelines, and every batch is 3rd-party lab tested for potency, sterility, pH, and endotoxins. Note that compounded medications themselves are not FDA-approved.
Compounded medications are not FDA-approved. Prescription products require an online consultation with a US-licensed provider. Individual results vary. This is not medical advice. NAD+ is not suitable for everyone. Tell your provider if you are pregnant, breastfeeding, or trying to conceive, if you have serious liver or kidney conditions, or if you have a history of significant cardiovascular disease, since they may advise against treatment. Common side effects are usually mild and dose-related, including injection-site redness or soreness, flushing, nausea, lightheadedness, headache, and a temporary feeling of chest or muscle tightness if injected too quickly. Seek medical care right away for any signs of an allergic reaction such as rash, swelling, or trouble breathing.
