I'm currently taking a cleanse system that I'm pretty happy with. It has ingredients like cayenne to scrub out colon debris. But it's really supposed to clean out your whole digestive tract, (intestines, liver etc). I've been taking it for a few months now and I've noticed a difference. I lost a lot of weight for one thing. I can refer you to the website if you're interested.
I have not tried 3lac so I am unsure how effective it is. What do you want to take it for?
