NAD+ works even harder in combination
Most patients who take NAD+ have more than one goal. These physician-curated protocols pair it with other compounds — supervised by one physician, delivered as one plan.

Regulated sourcesThe science behind NAD+
NAD+ powers how your cells make energy and repair DNA, and it drops as you age. Human studies show NAD+ boosters reliably raise it again; the deeper anti-aging effects are still mostly seen in lab and animal research.
Restores cellular NAD+
In the first human trial, a single dose measurably raised blood NAD+ — the fuel behind your cells' energy (Nature Communications, 2016).
Muscle insulin sensitivity
In a placebo-controlled trial, NMN improved how well muscles respond to insulin and use blood sugar, while placebo did not (Science, 2021).
Fuels DNA repair
In lab and animal studies, restoring NAD+ switched the cell's DNA-repair machinery back on and revived tired mitochondria (Cell Metabolism, 2016).
Healthspan in aging
Aging mice given NMN for a year gained less weight and kept healthier metabolism and energy, with no obvious downside (Cell Metabolism, 2016).

What patients are saying
"I'd come home and sit in my truck because I didn't have the energy to walk inside. Three months in, that's gone. I'm not 30 again, but I got the last five years back."
Robert M.
"By 3pm I was running on fumes and caffeine. Two weeks on the spray, I stopped reaching for that third coffee. The fog just... lifted."
Diane K.
"I assumed the tiredness was just getting older. Now I sleep better, recover faster, and I'm actually present with my grandkids instead of watching from a chair."
James T.
"Menopause hit me early and it wrecked me. Within a few weeks on the spray, I was waking up actually feeling rested. It gave me back a quality of life I thought was gone."
Sandra L.
"I was 44 but felt 60. Around week three it was like a dimmer switch got turned up. More focus, better workouts. I actually wanted to go for a run on Saturday instead of lying on the couch."
Michael R.
"My mother had Alzheimer's. That fear lives in me every day. Six months on NAD+ — my thinking is sharper, I do crosswords faster, I remember where I put my keys. Those little things mean everything when you carry the fear I carry."
Patricia H.
"I'd bike Saturday and be useless until Tuesday. Two months into injections, I'm riding both weekend days and feeling good Monday morning. That's not nothing when you're north of 50."
Tom W.
"After about a month, my husband noticed before I did. He said, 'You seem like yourself again.' That honestly made me cry."
Karen S.
"I'm a physician. I was resistant to the longevity supplement trend for years. But the research on NAD+ is hard to ignore. My inflammatory markers improved. My sleep got better. I'm not evangelizing — but I am continuing."
David C.
"After my second kid, I never bounced back. Everyone said, 'That's just mom life.' Three weeks on the spray, I finally have energy to play with my kids after work instead of just surviving until bedtime."
Angela M.
"I wasn't depressed — I was fading. Less energy, less sharpness, less drive. Three months in, I'm back in my woodshop, reading again, and I walked 18 holes for the first time in two years."
Richard P.
"Decision fatigue was crushing me. I'd get home and couldn't choose what to eat for dinner. Now I hold focus through afternoon meetings without my brain turning to cotton."
Lisa F.
"I gained 30 pounds between 40 and 47. I won't credit NAD+ for everything — but the energy to actually get to the gym came back first. And that made everything else possible."
Frank J.
"I'm a retired nurse, so I'm naturally skeptical. But the science behind NAD+ is real biochemistry, not marketing. The change was gradual but real. At 61, I'm getting more good days — and that's enough."
Margaret B.
"28 years as a firefighter. Chronic inflammation, joint pain, fatigue that sleep doesn't fix. The inflammation in my knees calmed down within the first month. I want to make it to retirement feeling strong. This is helping."
Steve A.
"I turned 46 and it was like someone flipped a switch. Four months on the spray, I signed up for a half marathon. I never would've done that six months ago."
Jennifer D.
"Grief ages you in ways people don't talk about. By 59, I felt 75. The injections didn't lift the grief — but the physical heaviness eased. I had energy to say yes when my daughter invited me to dinner instead of making excuses."
George N.
"I spent my 40s in survival mode. By 50, I'd been running on empty for years. The spray gave me steady energy — not jittery like caffeine. I feel like I can actually think, move, and be present again."
Catherine E.
"Two years ago I couldn't finish 18 holes. Started injections in the spring — by summer, I played three days a week on vacation. My swing isn't better, let's be honest. But my body doesn't punish me for playing anymore."
William H.
"I know 38 sounds young, but autoimmune issues had me aging faster than my peers. Four months in, my inflammatory markers improved. I have days now where I feel genuinely good — not just 'managing.' I forgot what that felt like."
Rachel G.

Frequently asked questions
NAD+ is a coenzyme your cells use to make energy and repair DNA, and levels fall as you age. Restoring it supports mitochondrial energy, focus, and cellular repair. In the first human trial, a single dose measurably raised blood NAD+ (Nature Communications, 2016). Most patients notice sustained energy within 2 to 4 weeks, along with less afternoon brain fog and faster recovery after exercise.
Human studies reliably show NAD+ boosters raise cellular NAD+ again. In a placebo-controlled trial, NMN improved how well muscles respond to insulin and use blood sugar (Science, 2021). The deeper anti-aging effects, like reactivated DNA repair and healthier metabolism in aging, are so far mostly seen in lab and animal research (Cell Metabolism, 2016). We describe it honestly: measured, evidence-grounded, not a miracle cure.
NAD+ comes in two formats. The injection is roughly 100% bioavailable, taken 2 to 3 times per week at home, with onset in 24 to 48 hours — best for a higher dose and faster results. The nasal spray is needle-free and travel-friendly, taken daily, with about 40 to 60% bioavailability and onset in 3 to 5 days. There are no clinic visits or infusion chairs.
Most patients notice sustained energy within 2 to 4 weeks. With the injection, onset is typically 24 to 48 hours; with the nasal spray, closer to 3 to 5 days. Beyond energy, people often report reduced afternoon brain fog, better focus and recall, and faster muscle repair with less soreness. Your physician monitors your progress and adjusts your protocol as your body responds.
Yes. After you complete the health intake, a licensed US clinician reviews your information — typically within 24 hours. Depending on your state and health profile, you may receive a prescription directly or be asked for a brief phone or video call. Once approved, your NAD+ is prepared and shipped with tracking updates. If a clinician determines you're not eligible, you won't be charged.
Yes. If you have a Health Savings Account or Flexible Spending Account, you can pay with your HSA/FSA card at checkout. Insurance is not required, and we accept all major credit cards with no hidden fees. If you need additional documentation for your administrator, email support@chia.health and tell us what they requested.
