I guess you have never lived with a pregnant woman taking those damn prenatal vitamins. My x wife used to kill it. It was soooooo bad I had to leave the room. I thought one time I might have to result to violence! It was bad!
probiotic and digestive enzymes. i consume over 400g a day and this has helped me out. i also switched to a goat whey, due to it being lactose free, this also helps.
Take digestive enzymes with your meals!
I eat a ton of protein training right now and even girls can get this issue. I use probiotics and enzymes and they help tons!
I get the chewable ones from MaxMuscle and they work great. I find the chewable enzymes work better than the capsules.
