NAD+ research has accelerated significantly over the past decade. Studies from Harvard, MIT, and the Salk Institute have established the link between NAD+ depletion and accelerated aging. Our physicians use this evidence to design your protocol — not guesswork.
Mitochondrial function
Shown to restore mitochondrial function in aging muscle tissue within 8 weeks of supplementation (Cell Metabolism, 2023)
Sirtuin activation
NAD+ directly activates SIRT1 and SIRT3 — the longevity proteins most associated with healthy aging and metabolic regulation (Nature, 2022)
Cognitive protection
Higher NAD+ levels correlated with preserved cognitive function and reduced neuroinflammation in adults over 45 (Neurobiology of Aging, 2021)
DNA repair capacity
NAD+ supplementation enhanced PARP-mediated DNA repair activity by 40% in human cell cultures, suggesting protective effects against genomic instability (Science, 2020)

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+ (nicotinamide adenine dinucleotide) is a coenzyme found in every living cell. It plays a critical role in energy production, DNA repair, and over 500 enzymatic reactions. NAD+ levels decline naturally with age — by as much as 50% by your 40s — which is linked to fatigue, cognitive decline, and accelerated aging. Chia’s NAD+ program is designed to help restore what time takes away.
As we age, our bodies accumulate more cellular damage. The enzymes responsible for repair (PARPs, sirtuins, CD38) consume more NAD+ to keep up. At the same time, production slows. The result is a steady decline that accelerates after your 30s and 40s, contributing to reduced energy, slower recovery, and increased disease susceptibility.
Research shows NAD+ supplementation reliably raises blood NAD+ levels by 130–150%. In preclinical studies, restoring NAD+ enhanced mitochondrial function, supported DNA repair, reduced inflammation, improved muscle regeneration, and activated sirtuins (longevity-associated enzymes). Human trials show promise in areas like improved sleep, reduced inflammatory markers, and better metabolic biomarkers — with larger long-term studies underway.
NAD+ levels begin declining in young adulthood and can drop significantly by your 40s. Some researchers suggest supplementation is unlikely to be beneficial before the early 30s, when decline becomes more measurable. Most Chia members are between 35 and 70. A Chia physician can help determine if it’s the right time for you.
NAD+ therapy may be most beneficial for adults over 32–35 whose natural levels have begun to decline — particularly people experiencing age-related fatigue, brain fog, slow recovery, metabolic changes, or chronic inflammation. NAD+ is not recommended for pregnant or breastfeeding women. Chia’s longevity physicians evaluate your eligibility and can prescribe the same day.
