I'm a doctor. I still couldn't find an NMN I trusted — so I built one.
I'm Dr. Nichole Williams, founder of Replenora. I started this company for people over 40 who want their old baseline back — and who are tired of being left guessing about what's really in the bottle.
Why I built Replenora
It started with the question my patients kept asking — and the answer I couldn't give them.
Somewhere after 40, the afternoons get harder. The fog rolls in after lunch. Sleep stops feeling like rest. I heard it from the people I cared for, and — if I'm honest — I started to feel it myself. The science behind it is clear: NAD+, the coenzyme our cells use to make energy, declines with age, and NMN is the precursor the body uses to support it.
So when people asked me which NMN to take, I went looking for one I could stand behind. What I found alarmed me. Independent lab testing has repeatedly found that most top-selling NMN products contained a fraction of what their labels claimed — and some contained none at all. People were paying premium prices for capsules of filler. As a physician, I couldn't recommend any of it in good conscience.
That question became Replenora. Not another blend with a long ingredient list hiding the dose. Not a subscription you have to fight to cancel. Just one clean ingredient, tested by an independent lab, with the results published for the exact batch in your hands. The supplement I wished I could have handed my patients — built to the standard I'd want for my own family.
What I found when I looked closer
The NMN market has a trust problem. Replenora is my answer to it.
Independent testing of top-selling NMN supplements has exposed, again and again, how little of what's promised actually ends up in the bottle.
When fraud is the norm, transparency isn't a marketing angle — it's the entire reason a brand deserves to exist.
What I stand for
The standards I built Replenora around
No hype, no miracle claims, no fine print designed to trip you up. These are the rules I won't break.
Every batch is tested by an independent, A2LA-accredited ISO 17025 laboratory, and we publish the Certificate of Analysis. You read the receipts before you buy — not after.
500mg of pure β-NMN per capsule. No proprietary blends that disguise underdosing, no kitchen-sink ingredient lists. What's on the label is what's in the bottle.
One-time purchase only. We will never auto-bill you, lock you into autoship, or bury a cancellation in a help center. Buy once, decide for yourself.
Manufactured in an FDA-registered, GMP-certified US facility and third-party tested before every batch ships. Realistic expectations, backed by a 90-day guarantee.
We show you the receipts
I'd rather show you than ask you to trust me.
For Batch #5370, an independent, A2LA-accredited ISO 17025 laboratory verified the potency and screened for heavy metals. We publish that report so you can check our work — the same way I'd want to before recommending anything.
- ✓506mg β-NMN verified — above the 500mg label claim, not below it.
- ✓Lead, arsenic, cadmium, mercury: Not Detected on accredited testing.
- ✓Batch number on the bottle matches the report — so the proof is for the product you actually receive.
Who this is for
For people who want their baseline back — not a miracle
Replenora isn't for people chasing the promise of living to 120. It's for the person who remembers what their energy felt like ten years ago and wants a credible, honest way to support getting it back.
If you're tired of the 2 PM wall, skeptical of supplements that did nothing, and done being burned by counterfeits and subscription traps — you're exactly who I built this for.
