Beta-hydroxybutyrate (BHB) is a ketone body that reflects the body’s shift to using fat as a primary fuel source. Produced by the liver from fatty acids during fasting, carbohydrate restriction, or intense exercise, BHB provides an alternative energy supply — particularly for the brain — when glucose is limited. It is a key marker of ketosis, a metabolic state associated with fat metabolism.
Testing for Beta-hydroxybutyrate (BHB) levels can be beneficial for several groups of individuals:
High levels of Beta-hydroxybutyrate (BHB) can be indicative of a state of ketosis, which may occur in various contexts. The symptoms associated with high BHB levels can vary depending on the underlying cause:
Regulating Beta-hydroxybutyrate (BHB) levels involves managing the factors that lead to ketone production in the body. Here are some key approaches:
Several factors can affect Beta-hydroxybutyrate (BHB) levels in the body:
