YES! Look into a pro-biotic sup. Also, greatly increase intake of fruits/veggies. If your digestion is messed up you won't make gains. Also, I started drinking RAW MILK 4 mo ago & my stomach issues & chronic heartburn are gone. Men over 40, look into Colonic Irrigation. The diet here in USA: white bread, flour, etc lines the intestines after years. Look into this: I can personally vouch for its effectiveness.
