After hysterectomy I am on “the cleaner.” from gnc It’s a total body cleanse and the only thing that keeps me regular. Not only does this clean your colon (not runs, but naturally cleanse) but it cleans liver lungs and kidneys. You feel an over all difference after the 7th day. Bottle comes in 2 / 7 day doses. I take Well worth it. Can not live or function without this product. Once your cleansed that first week you stop taking and start eating better. This stuff will have you feeling so much better with a lot more energy. After that first dose of you change your diet you should only do this every 3 months. 7 days to a better healthier pain free You is worth it.
