Endurance evidence brief
Ketone esters and ketone salts raise blood ketones without carbohydrate restriction. Claims usually center on endurance, focus, fat burning, and low-carb performance.
Raises blood ketones, but systematic reviews do not show reliable acute performance improvements.
Systematic reviews report higher ketones without consistent acute endurance or power-performance gains.
Products differ substantially between ketone salts, esters, and precursors; cost and tolerability are major issues.
Do not confuse ketogenic diets, medical ketone research, and acute exogenous ketone products.

The score reflects evidence that the supplement does its stated job. Some jobs are direct, such as strength, endurance, or recovery; others are indirect, such as sleep, mood, appetite, or health support. A real effect can still receive a cautious practical rating when dose, safety, product quality, or audience fit remain uncertain.
