I recently wrote about how a novel ketone ester drink may help boost performance in professional athletes, but
while ketone supplements are still in development, your best bet at the moment is to use MCTs found in foods and supplements, which your body will then convert to ketones.
In several studies,
supplementing with
ketone salts resulted in beta - hydroxybutyrate levels of less than 1 mmol / L,
while taking
ketone esters raised blood beta - hydroxybutyrate concentrations to 3 to 5 mmol / L (26, 27, 28).
