What it’s for
- Studied for metabolic and exercise effects
Ketone salts or esters taken to temporarily raise blood ketone levels.
Purpose, evidence and practical considerations.
These products raise blood ketones, but reviews do not show a dependable exercise-performance benefit. Esters and salts have different compositions and tolerability.
Confidence: moderate
Common issues include nausea, diarrhea, poor taste, and mineral load from ketone salts. Exogenous ketosis is not the same metabolic state as fasting or a ketogenic diet.
Ketone esters and salts can raise circulating beta-hydroxybutyrate without carbohydrate restriction. Esters generally produce higher ketone exposure than salts, while salt products add a mineral load.
Regulatory status: dietary supplement or food product; product status varies by composition and jurisdiction
