Roll Call does not check drug interactions or assess personal safety.

A ketone body the body naturally produces during fasting or carbohydrate restriction, sold in supplement form as a mineral salt or ester.

Why it’s used

Taken to raise blood ketone levels directly, with the intent of supporting energy, appetite control, or a ketogenic-style metabolic state without strict dietary carbohydrate restriction.

What the evidence says

Human research on exogenous ketone supplements is still limited. Small trials show that these products do transiently raise measurable blood ketones and can affect appetite or exercise metabolism in the short term, but findings on meaningful performance or metabolic benefits are inconsistent and the body of evidence remains thin.

Context

Studies have generally used single or short-term dosing to observe changes in blood ketone levels rather than long-term outcome trials.
