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.
Can drinking ketones help the heart pump better?
Strong support Yes in heart-failure patients, but trials are short, from one group, and measure performance not survival.
Do ketones switch off NLRP3, a key inflammation trigger?
Strong support Yes for the acid form, but only shown in cells and mice — and the salt sold in supplements appears inert.
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.
