I am surprised about the ingredients of Colosan, before it was the same as Oxypowder . Oxypowder was the first one that came out with capsules and Colosan was originally a powder and you had to add the lemon juice separately. The object is to get oxygen in the colon. The Oxypowder has only 3 ingredients, but I could not find a label to read from Colosan but I would think it
might be the same, at least it used to be. I prefered Oxypowder since they also added germanium, but it is no longer on the label. http://www.oxypowder.com/ingredients
