David Sinclair on Exogenous Ketones — 9 claims
“in 2021, a randomized trial testing the effects of a ketone on adults with obesity showed improved processing speed, improved working memory, and more blood flow in the brain, which is increasingly important as you get older.”
A 2021 randomized trial found that a ketone given to adults with obesity improved processing speed, working memory, and brain blood flow.
“a study from 2022 where researchers gave participants ketone monoesters before a soccer match and measured their reaction time and other aspects of cognitive performance.”
A 2022 study found that giving participants ketone monoesters before a soccer match improved reaction time and other aspects of cognitive performance.
“In 2012, for example, the first study of its kind showed that consuming an exogenous ketone raises blood beta hydroxybutyrate levels to that typically seen during a long fast or a ketogenic diet.”
A 2012 study showed that consuming an exogenous ketone raises blood beta-hydroxybutyrate levels to those typically seen during a long fast or ketogenic diet.
“a 2025 randomized placebo-controlled trial tested Ketone IQ in healthy college-age adults. They performed 10-second sprints on stationary bikes. Each participant consumed half a gram of R-1,3-butanediol per kilogram of body weight per day for a week. Amazingly, Ketone IQ improved peak power by 10% and average power by 16%”
A 2025 randomized placebo-controlled trial found that Ketone IQ (R-1,3-butanediol) at 0.5 grams per kilogram of body weight per day for one week improved peak power by 10% and average power by 16% in healthy college-age adults performing sprint exercises.
“a study published in Alzheimer's and dementia asked what fuel can the aging brain still use. As cognitive impairment progressed, the researchers found that the brain became less able to use glucose, its usual fuel. And what actually happened was that ketone uptake remained relatively preserved. That's really important because it suggests that even when the aging brain struggles to use sugar for energy, it can probably still use ketones as the alternative fuel.”
A 2018 study published in Alzheimer's and Dementia found that as cognitive impairment progressed, the brain became less able to use glucose but ketone uptake remained relatively preserved, suggesting the aging brain may still use ketones as an alternative fuel even when it struggles to use glucose.
“Ketone IQ is a drink whose active ingredient is a ketone precursor called R13 butin dial. Now you don't have to remember that. What's interesting is that your liver converts the drink into beta hydroxybutyrate which your brain and your muscle can use for energy.”
Ketone IQ's active ingredient is a ketone precursor (R-1,3-butanediol) that the liver converts into beta-hydroxybutyrate, which the brain and muscles can use for energy.
“by cutting back on carbohydrates, what you're actually doing is flipping a switch that tells your body to start producing these molecules as an alternative energy source besides glucose.”
Cutting back on carbohydrates flips a switch that tells the body to start producing ketones as an alternative energy source besides glucose.
“I'd like to know amino acid levels, ketones, um inflammatory molecules, sex hormones if possible.”
Sinclair expresses interest in measuring ketone levels continuously via a wearable device.
“I've long been interested in how fasting may affect brain health. And you've likely heard of ketones in the context of the ketogenic diet or in fasting.”
Sinclair has long been interested in how fasting may affect brain health, in the context of ketones.
