3-hydroxy Butyric Acid Potassium Salt

3-hydroxybutyric acid potassium salt is a type of ketone body, which the body produces when it breaks down fat for energy. It can be synthesized for use as a food ingredient. It is often produced through fermentation processes.

This ingredient is often added to foods as a source of ketones, particularly in products marketed for ketogenic diets. It may also function as an acidity regulator. It is found in snack bars, chips, and other snack foods.

3-hydroxybutyric acid potassium salt is generally recognized as safe (GRAS) by the FDA for use in food. Ketone bodies are a natural energy source for the body, and supplemental intake is a key feature of ketogenic diets. Regulatory bodies like JECFA and EFSA have evaluated related compounds, but specific evaluations for this salt may vary. Research into the long-term effects of supplemental ketone intake is ongoing.
