Like "They keep your gut working well and I have heard that a healthy gut helps you loose weight better. If your doctors give you the okay, you may also want to talk to the pharmacist to see which brand they recommend. I don't know about the pill version. I have never done that. But I have used it in yogurts and fermented foods. Those are the more natural ones, but the pills were recommended to my husband last year after his lengthy stay in the hospital when he was on a lot of antibiotics. It's the only way he really gets them added back, as he's not into probiotic foods much."
