I have no idea how this occurred. What I do know is that a week or two after starting Endoluten an issue I was having with my kidneys cleared up. For a year or two previous to this time I was having a great deal of foam in my urine and my BUN blood work results were on the less than perfect side, in spite of my best efforts over the last 24 months to correct this. I haven’t had any blood work since the disappearance of the telltale symptoms, including the kidney area discomfort I had been experiencing. I’m not recommending anything to anyone, specifically sharing my personal experience.
