Instead of reaching for a sugary sports drink, what if you had something that helped your heart pump more efficiently, improved oxygen flow to your muscles, and support circulation—all without the sugar crash?
Scientists have been testing exactly that. Their secret weapon? Ketone drinks.
A January 2025 study by Perrisiou et al. investigated whether drinking ketones (instead of producing them through diet) could support heart health—especially in people with type 2 diabetes. And the results? Promising.

The Heart’s Preferred Fuel—And Why It Matters
For people with type 2 diabetes, heart function can take a hit. Circulation slows, muscles struggle to get oxygen, and the heart has to work harder to pump blood—like trying to run a marathon while breathing through a straw.
Normally, the heart burns glucose (aka sugar) and fatty acids for fuel. But here’s the twist: it actually prefers ketones. Ketones are a cleaner, more efficient fuel source that requires less oxygen to do the same job—they’re like a premium-grade fuel.
So, researchers asked: If we give people with diabetes a shot of ketones, could we help their hearts work better?
The Study: Testing Ketones for Heart Health
Thirteen adults with type 2 diabetes participated in a double-blind, placebo-controlled study—meaning neither the participants nor the researchers knew who was drinking ketones vs the placebo.
After drinking a ketone monoester drink (which is known to taste somewhere between nail polish remover and regret, unlike Kenetik), researchers measured:
- Cardiac Output: Amount of blood the heart pumps per minute, a key indicator of heart health
- Stroke Volume: Amount of blood the heart pumps per heartbeat, a key indicator of heart strength
- Muscle Oxygenation: Amount of blood flowing through the muscles that carries oxygen, essential for endurance and recovery
- Vascular Function: How well blood vessels relax and expand, a key indicator of how well blood flows through the body
Then, they put participants through a cycling test to see how their bodies responded.
The Results: A Win for the Heart, A Question Mark for Circulation
Good news: The ketone drink boosted cardiac output and stroke volume—meaning the heart pumped more blood, more efficiently. Even better, muscle oxygenation improved, which could help people with diabetes feel less wiped out after exercise.
Less impressive news: The drink didn’t improve blood vessel function. So while ketones may support heart health, they’re not a magic fix for circulation problems—at least not in one dose.
Should Ketones Be Part of a Heart Healthy Diet?
Not so fast. While the study’s findings are exciting, this was a small trial. We don’t yet know if drinking ketones regularly is a game-changer for heart health or just an expensive experiment.
What we do know:
- Ketones are powerful fuel. They’re incredibly efficient. Your heart loves them. Your muscles love them.
- Ketones don’t replace exercise or diet. If you were hoping to swap cardio for a ketone drink, science isn’t on board (yet).
- Ketones may help people with diabetes. If further research confirms these effects, ketone drinks could become a valuable tool for supporting heart function. in metabolic diseases.
For now, the best strategy? Stick with what’s been proven to work—regular movement, good nutrition, and keeping blood sugar in check. As research evolves, we may see a future where optimizing heart health includes ketones in a bigger way.

The Future of Ketones for Heart Health
This study is part of a growing body of research exploring the benefits of ketones way beyond weight loss. While more research is needed, ketones could become a key player and metabolic and cardiovascular health.
For now, if you spot a can of ketones on the shelf or drinkkenetik.com, give ketones a try! Just know: science is interested in their benefits for heart health, but not fully convinced—yet.
