Recent research has demonstrated that the consumption of exogenous ketones delivers groundbreaking benefits for endurance athletes.

Notably, a group of well-trained recreational cyclists ingested 2 daily doses of ketone esters during a 3-week training block.  They exhibited a 40% increase in capillary development and a 26% increase in serum EPO, which translate into a meaningful ergogenic boost.

Furthermore, when ketones were combined with a bicarbonate supplement, cyclists saw a 5% increase in power.

Exogenous ketones have already transformed World Tour cycling, and are increasingly making their mark in triathlon.  Many pros are sponsored by ketone manufacturers, and well-heeled age groupers have access to this expensive but promising supplement.  It might be time for you to give them a look.
