There are two pathways that have been studied about how you go from moving your body to more BDNF that that neurotrofen that's uh that's um increasing the growth of new hippocample brain cells. The two pathways are the following. One is a myioine which is a protein released by the muscles. [...] Pathway number two comes through the liver. [...] there is a uh ketone um beta hydroxybutyrate that we've known for a very long time that gets released by the liver during exercise. And we also know that that particular ketone passes that bloodb brain barrier and it's another stimulant for BDNF.
