Interesting article in Nov 2021 edition of Rouleur regarding use of ketone esthers in pro cycling, and whether or not it can significantly improve performance. As of today, use of ketones are not a banned substance. They are expensive. I wonder how elite runners/marathoners use them?
I'm not ready to concede that a 5% improvement in the study for the group of recreational cyclists taking both ketones and sodium bicarbonate (but neither alone) was necessarily probative. That's not a huge difference in a study with so few people. I'd like to see something much larger over a longer period to prove that.
