(R)-3-hydroxybutyric acid

(R)-3-hydroxybutyric acid, often referred to as beta-hydroxybutyrate (BHB), is a naturally occurring compound in the body that plays a key role in energy metabolism. During periods of fasting or intense exercise, the body breaks down fats to produce BHB as an alternative energy source for cells, especially in the brain. It is part of a group of substances called ketones and has gained attention for potential health benefits, including weight loss and improved mental clarity. BHB is also used in dietary supplements for those following ketogenic diets.
