I just found out. Is it too late?

It is not. APOE4 raises lifetime Alzheimer's risk roughly 4–5× above baseline, but it does not seal fate. The members with the largest biomarker swings are the ones who started in their fifties and sixties, every year of intervention bends the curve.

I am joining for a parent, partner, or someone I love.

You belong here too. Most of us started exactly where you are — 88% of members have a family history of Alzheimer's, and for nearly half it was their mother. Caregivers and family members get the same tools, pod, and expert access as every member, alongside people who have walked exactly your road.

I am not a biohacker.

Neither are most members, average member is a 58-year-old woman. The app walks you through every step, your pod keeps you honest, and Dr. Tran is one message away.

I am 3/4, not 4/4. Does this apply?

Yes. Phoenix is built for any APOE4 carrier. The urgency dial is lower, the playbook is the same.

Yes, any time, one click, no questions. 60-day full money-back guarantee on your first quarter.

How do I get the $100 off?

Click any "Get $100 off" button on this page, then enter code PHOENIX at checkout on neuronic.online. The discount applies to the Neuronic Light ($1,795, so code PHOENIX brings it to $1,695). It stacks on top of the 90-night money-back trial, so there is no risk in trying it.

What did the study actually find?

Over four months, APOE4 carriers using the helmet inside Phoenix showed real, measurable signals. Memory was the one cognitive domain to improve with statistical significance (20 of 25 participants improved, p = .010). On the nights people ran a session, every sleep metric improved, more total sleep, more REM, more deep sleep, faster to fall asleep. Insomnia symptoms eased. Mood and energy held steady for four straight months. A couple of individuals shared striking personal results (a 75% drop in IL-6 inflammation; a 5.7-point gain on a standard Alzheimer's cognitive scale).

Is this proof the helmet works?

No, and we will not pretend otherwise. This was a first, real-world study, not a randomized controlled trial. It was small, the strongest sleep findings come from a single participant tracked daily, and there was no placebo group. We read it as a genuine, encouraging signal worth scaling, not as final proof. That honesty is the point: the next study, with more carriers and a control arm, is already being designed.

Neuronic Light or Neuradiant 1070, which one?

The carriers in our study used the Neuronic Light, Neuronic's portable 1070nm helmet, so that is the device this offer is built around. If you want exactly what we studied, choose the Neuronic Light ($1,795, or $1,695 with code PHOENIX). Neuronic also makes the Neuradiant 1070, a higher-end clinical model with more LEDs and 4-quadrant control, if you want the top of their range.

Do I have to be a Phoenix member to use the code?

No. Code PHOENIX works for anyone. But here is the thing, this study only existed because Phoenix members track their own bloodwork, sleep, and cognition over time. If you want to be in the next study (and get the data, community, and APOE4-specific tools that make it possible), that is what Phoenix is for.

Is Neuronic a Phoenix product?

No. Neuronic is an independent company. We ran a study with them because their device was worth testing, and we are sharing the results openly. Phoenix may earn an affiliate fee that funds free content and member benefits; that fee does not influence which partners we choose or what the data says.

What if it does not work for me?

Neuronic offers a 90-night home trial. If the helmet is not right for you, they cover return shipping and refund the full amount. The decision is reversible, your money is not stuck.

Phoenix × Neuronic · the study

We didn’t just partner with Neuronic. We studied it.

Four months. APOE4 carriers (64% with two copies of the gene, the highest risk there is). Cognition, sleep, bloodwork and daily check-ins, all tracked continuously inside the Phoenix platform. Here is what the data showed.

20 / 25

carriers improved on memory

the one cognitive domain that reached significance (p = .010)

+32 min

more sleep on session days

plus more REM and deep sleep (Oura, single participant)

−75%

drop in IL-6 inflammation

one participant over ~3 months (6.1 → <1.4 pg/mL)

4 months

mood + energy held steady

no decline across the whole protocol

Memory led the way

Change across five thinking skills (CogniFit, 25 participants). Memory is the area most tied to early Alzheimer’s risk, and it was the clear winner.

Memory+7.4 · p = .010

Reasoning+4.9 · p = .071

Perception+4.2 · p = .106

Attention+1 · p = .893

Coordination-0.1 · p = .867

Significant (p < .05)Promising (p = .05–.11)

Four individual skills passed the strict bar on their own: Naming, Non-verbal memory, Visual perception, Working memory.

On session days, sleep improved

One participant, tracked night after night for months. Every metric moved the right way (all p < .01).

+32 min

total sleep

+10.5 min

REM sleep

+7.8 min

deep sleep

−13.7 min

to fall asleep

+6.6 pp

sleep efficiency

+2.4 pts

daily readiness

Gains built up over weeks (sleep at week 4, readiness by week 2), the slow, steady pattern you’d expect from a real response. Insomnia symptoms eased too (median −2.5 on the ISI).

One participant · inflammation

6.1 → <1.4

IL-6, a key inflammatory marker, fell more than 75% over about three months. The direction you hope to see.

Another participant · cognition

19 → 13.3

A 5.7-point gain on the ADAS-Cog13, a standard Alzheimer’s assessment where lower is better. A meaningful individual result.

Read honestly: this was a first, real-world study, small, with no placebo group, and the strongest sleep findings come from a single participant. We see a real signal worth scaling, not final proof. The next, larger study is already being designed.

How it works

Light, where your brain can use it

1070nm near-infrared light

Invisible, gentle infrared light at a wavelength chosen to pass through the scalp and skull and reach brain tissue, far deeper than visible light can go.

Energy for tired neurons

That light is absorbed by mitochondria, the tiny power plants inside your cells. The process is called photobiomodulation. The aim: help brain cells make energy more efficiently.

A few minutes a day

You wear the Neuronic Light like a helmet for a short session, set intensity and pulse in the app, and get on with your day. That is the whole protocol.

From Kevin

Why we tested Neuronic ourselves

Members kept asking me the same thing: does the light-therapy helmet actually do anything, or is it expensive hope?

I did not want to guess. So instead of slapping an affiliate link on it, we ran a study. Four months, real APOE4 carriers, real bloodwork and sleep and cognition, all tracked inside Phoenix.

The results were not a miracle, and I would not trust anyone who told you they were. They were something better: a real, measurable signal. Memory moved. Sleep moved. People felt steady for four straight months. That is enough to take it seriously, and enough to design a bigger, tighter study next.

Neuronic earned the recommendation the hard way, with data. That is the only way anything earns a spot in front of this community.

This study only happened because members track their own data.

Phoenix is the platform that turned scattered sleep, bloodwork and cognition into a real study, for APOE4 carriers, built by an APOE4/4 carrier. Join us and you’re not just reading the next result. You’re in it.
