Do exogenous ketone supplements work? The big test

Do exogenous ketone supplements work? Can they make you lose weight, improve your mental abilities or your physical performance?

As the keto diet increases in popularity, we are seeing an explosion of keto-related products coming onto the market. Many people use exogenous ketone supplements to enhance their keto lifestyle, and the companies who sell them make many wide-ranging claims about their benefits for your health.

But are they a groundbreaking boost to a low-carb or keto diet, or should you be wary of the broad claims that companies make about their benefits?

In short: do they work? And if so, what brand should you choose? That’s what we wanted to find out when we ran a big experiment on exogenous ketones at our head office in Stockholm. Watch the video at the top of this page, or head over to our full writeup with all the results from the experiment:

    The only supplements that I use are for minerals such as Magnesium. I also take an Activated Charcoal as well as a good probiotic then, be sure to feed the probiotics high in alkaline, low in acid pre-measured unrefined carbs( spinach, cabbage, raspberries) with quality fat such as real butter, coconut oil, olive oil and cold-pressed avocado oil. A good source of high-quality grass-fed protein for omegas as I am allergic to seafood.
    For me, this has produced tremendous weight loss results, good digestion and a surge of energy. But to each their own.

    A bit of fun but I assume that that all the subjects were already in ketosis. Maybe it has benefits for people that aren't in ketosis? That might have been a better test.

    I eat real food and no processed stuff. This is what I've learned going into LCHF/Keto. So why go backwards to the SAD method eating processed supplement like exogenous ketone? Is it so hard to get un-brainwashed?

    Carnitine is apparently an input to the ketone production process.... could this explain some of carnitine supplementation benficial effects ?
