Fibroblast growth factor 19 (FGF19)

Fibroblast Growth Factor 19 (FGF19) is a hormone produced primarily in the intestines after eating. It plays a key role in regulating the body’s bile acid levels, which are essential for digesting fats. FGF19 signals the liver to reduce bile acid production, helping maintain balanced levels. Additionally, it influences energy metabolism, including how the body manages sugar and fat. Proper FGF19 function is important for digestive health and metabolic balance, and variations in its activity have been linked to conditions like liver diseases and metabolic disorders.
