Qitone Review at 71: Seven Months of Honest Results

At the DaVinci 50 gathering, half the room was stirring a white powder into their morning coffee. I asked what it was. They explained it, I listened, and when I got home I ordered some. That is the whole origin story. No research rabbit hole, no podcast episode that convinced me — just a room full of people I respect all doing the same thing, and me being curious enough to ask.

That was about seven months ago. I have taken it every morning since. Here is the honest report.

What Is Qitone, and How Is It Different From Ketone Salts?

Qitone is a flavorless powder that raises your blood ketones without you having to fast or cut carbohydrates. It was formerly sold as Juvenescence Cognitive Switch, and it was developed in partnership with the Buck Institute for Research on Aging.

Most ketone products on the shelf are ketone salts — beta-hydroxybutyrate bonded to sodium, potassium, magnesium or calcium. They work, but they bring a salt load with them and a taste most people describe as punishing. Qitone takes a different route. It is a precursor: your digestive system breaks it into a C8 medium-chain fat and (R)-1,3-butanediol, and your liver converts those into beta-hydroxybutyrate — the same ketone your body makes when you fast. The ingredient list is three items long: Qitone precursor, sodium caseinate and soluble corn fiber. Worth knowing if you avoid dairy: the sodium caseinate means it is not dairy free, though it is very low lactose.

The company says levels start climbing within 20 to 30 minutes and stay up for around four hours. They have completed a self-affirmed GRAS safety determination.

Why I Take It

Two reasons, and I want to be straight about both.

The first is the one above — the DaVinci 50 room. When a group of people who take this stuff as seriously as I do all converge on the same product independently, that is worth a look. It is not evidence. It is a reason to run the experiment.

The second is that the mechanism makes sense for someone my age. As you get older your brain becomes less efficient at pulling in glucose for fuel. Ketones are a second fuel line that does not depend on that same machinery. Raising them without a three-day fast is a genuinely appealing idea at 71.

What Does the Research Actually Show?

That exogenous ketones raise blood ketones is settled. That raising them makes a healthy person think or feel better is not.

The best summary is a 2026 systematic review and meta-analysis in Frontiers in Nutrition (doi 10.3389/fnut.2026.1802531), which pooled 29 randomized trials. It found modest but statistically significant cognitive improvements, in both healthy and cognitively impaired people, with the effect depending on which supplement and what dose. Ketone esters and MCTs both showed a real signal.

Now the part a product page will not tell you. That meta-analysis was written by researchers at the Buck Institute — the same institute Qitone was developed with. That does not make it wrong; it is published, peer-reviewed, and its methods are open to inspection. It does mean you should know who did the work before you treat it as independent confirmation.

The second caveat matters more for people my age. Almost all of the underlying research was done in athletes, in younger adults, or in people who already have a deficit — metabolic syndrome, mild cognitive impairment, Alzheimer's. Those are the groups where you would expect to detect a benefit, because there is something broken to fix. The trial work in healthy older adults is thin. A 12-week study of a ketone ester in adults over 65 was a pilot, and it was powered to answer whether we tolerate the stuff safely — not whether it makes us sharper. Cognitive and physical outcomes were exploratory.

So the honest position is: plausible mechanism, real signal in the pooled data, and nobody has yet run the study that would tell a healthy 71-year-old whether this does anything for him.

My Dose and Timing

One scoop every morning, stirred into my coffee. That is it — no cycling, no loading, no second dose later in the day.

One practical note that no review seems to mention: it does not dissolve well with a spoon. I use a small handheld milk frother and it mixes perfectly in about five seconds. If you stir it by hand you will get clumps floating on top and you will hate it. Get a $12 frother.

It goes into one of the four coffees I drink every morning, which I have written about in my coffee protocol. Flavorless is an honest claim — I cannot taste it in the cup.

What Have I Actually Noticed After Seven Months?

Nothing.

No lift in energy I can point to. No sharper mornings. No difference I would have detected if someone had swapped it for cornstarch without telling me. Seven months is long enough that I would expect to know.

There is one objective thing, and I want to be careful with it. My last blood panel showed my ketones were up. That is a real measurement, from the same blood testing I do twice a year, and you can see the numbers on my results page.

But read that correctly. Elevated ketones prove the powder does what it says it does. They do not prove the elevation is doing anything for me. That is the gap at the center of this entire category, and my own bloodwork sits right in the middle of it — the product works, and I still cannot tell you it is working.

Would I Tell Someone Else to Take It?

I would, with the caveats above sitting in plain sight.

I like it in my coffee. It is easy, it is genuinely tasteless, it has not upset my stomach once in seven months, and it is doing the measurable thing it claims to do. For me that is enough to keep going, because the case for ketones as a second brain fuel is mechanistically strong and I would rather be on the right side of it if it pans out.

Who should skip it: anyone who needs to feel a supplement working to justify the cost, because you may well feel nothing. Anyone avoiding dairy, because of the sodium caseinate. Anyone on a tight supplement budget — this is not cheap, and if you are choosing between this and something with harder evidence behind it, choose the other thing. And if you have kidney or liver problems or you are diabetic, talk to your doctor before adding ketones to your day, because you are changing how your body handles fuel.

Ask me again in January, when the next blood panel lands.

Keep Going

Everything I take is listed with its dose on my supplement stack and on my protocols page. What I do to stay strong is on my fitness page, and every blood number I publish is on my test and stats page.

A note from Gary: I am not a doctor, and I am definitely not your doctor. I am a 71-year-old man running a 129-year experiment on himself in public. Exogenous ketones change how your body handles fuel, which matters if you are diabetic or have kidney or liver disease. Talk to your physician before changing anything you take.
