I swear that I have not had an upset stomach or come down with the usual sniffles or cold since taking Bio X4. I think it must be the probiotics. I have more energy as well and don't have to drag myself into the kitchen to cook or make yogurt (which is one of my favorite things to do). I only need one cup of coffee to make it through the day and may try to switch to decaf at a later date to test if I am no longer dependent on caffeine. My brother and sister in law are also taking Bio X4 and one thing we all have in common is a suppressed appetite. I can actually stop eating when I want to. To be honest, I get so very full so fast that I can't seem to eat my usual portions. Not complaining about that. All in all, I think best reasons to take this is for appetite suppression and probiotics benefits.
Bottom Line: Yes, I would recommend this to a friend
