exogenous ketones
Ketone salts/esters that raise blood BHB without carb restriction. They reliably raise ketones and blunt post-meal glucose, with real cardiac-output and anti-inflammatory (NLRP3) signals — but they do NOT improve exercise performance, a common marketing claim.

The 5 claims about exogenous ketones
Each keeps its own verdict — we never average them away.
Do ketone supplements actually raise blood ketones?
Strong support Yes — this is the one firmly proven effect, though the rise is only temporary.
Do ketone drinks lower blood sugar after a meal?
Strong support Yes, modestly and short-term, but they don't improve long-term blood-sugar control.
Do ketones switch off NLRP3, a key inflammation trigger?
Insufficient Not in people. The acid form switches NLRP3 off in cells and mice, but the two human tests found no inhibition, or the opposite, and the salt sold in supplements appears inert.
Can drinking ketones help the heart pump better?
Leans support Yes in heart-failure patients, but trials are short, from one group, and measure performance not survival.
Do ketone sports supplements boost athletic performance?
Leans against Probably not — pooled trials show no net benefit, and the famous positive study was industry-run and failed to replicate.
