I'm usually apprehensive when taking supplements, but I bought this product and use it in addition to the Probiotic Slim + Prebiotic Fibre. I do not take all the daily recommended dosage, so it took me about 2 weeks to notice the change. There's a marked difference in my digestion; the bloated feel and look have disappeared, and there's a noticeable boost in my energy levels. I usually take them before my gym workout, which helps me through those sessions nicely.
