Summary and Conclusion: BHB – A Metabolic Multitasker

BHB, the most abundant ketone body, is a versatile molecule that plays a crucial role in energy metabolism and potentially offers a range of health benefits. While it’s naturally produced by the body during fasting or carbohydrate restriction, exogenous ketones have also gained popularity as a way to boost ketone levels. Further research is needed to fully understand the long-term effects and safety of ketosis and ketone supplementation, but the existing evidence suggests that BHB may be a powerful tool for optimizing metabolic health and potentially preventing or managing various chronic diseases.
