What a fantastic product! I didn't experience anything for the first week. Around the second week I started seeing wisps of something in my urine. I kept on seeing more and more - I was finally filtering! The product has given me more energy, I don't have to take naps anymore, and I'm experiencing a vitality that I had not experienced previously, even though I was on a 75% fruit diet. It's a great complement to my routine and my body is loving it. Tip: I took it alongside the Lymphatic System cleanse and finished both products at the same time. Now I've graduated to the Kidneys & Bladder II - Tincture. I continue to filter as before. Everyone should give it a try.
