Gallensäuren sind für die Fettverdauung essentiell, greifen
aber auch regulierend in den Energiestoffwechsel ein.
Gallensäuren werden in der Leber hergestellt und in den Darm
abgegeben, wo sie der Resorption von Fetten und fettlöslichen Vitaminen dienen.
Die Säuren gelangen dabei über den Blutkreislauf zurück zur Leber, so dass ein
geschlossener Gallensäurekreislauf entsteht.

Tierversuche haben gezeigt, dass die orale Aufnahme von
Gallensäuren zu einem verringerten Gewichtsanstieg und zu einem höheren
Energieverbrauch führt und dass nach einen Magenbypassoperation der
Gallensäurespiegel im Blut ansteigt.
