I bought this because it contains prebiotics, probiotics (a great deal of them), and antioxidants. I figured I was getting my bang for my buck at the time. What I didn't know is 1. that this company is owned by Nestle, one of the most heinous companies on the planet (they use child, slave labor on chocolate plantations, capitalize on commons like water and steal that water from local communities that need it, etc.) and 2. that there are side effects to probiotics including nausea, flatulence, and diarrhea. This is why it is recommended the average adult consume 5-10 billion strains of probiotics per day. Not only does this product contain FIFTY billion strains of probiotics, nearly 5 times the recommended dosage, but it recommends you take TWO pills a day, that's nearly 10 times the recommended dosage. While this isn't harmful per se, it dramatically increases the likelihood of symptoms like nausea, cramping, flatulence, bloating, and diarrhea. I quickly realized that two pills a day was far too much, but even taking one a day, before bed, on an empty stomach, my body has been wrecked for the past week and I'm sure that these pills are why. Be very careful about products like this. Because of the dosage and the association with Nestle, I will NOT be repurchasing
