It depends on what your using that's causing your cleansing at a snails pace. Some otc products you buy for cleansing doesn't use pure and potent ingredients. They are designed to make money. They put the cheapest ingredients in these products and they don't work. You may also not be absorbing what you are taking in either. I've seen stool in the lab I work in with pills passed still intact, having never been absorbed. So you see this person is wasting money on these pills because they never disintegrated in his digestive tract.
Sometimes when you take a large amt of one vitamin like this calcium citrate, I think you stated, may not be good either. Vitamins work together and when you take too many of one and not enough of another may cause imbalances.
