To be honest, I spoke with many doctors regarding this product and they all say that it removes heavy metals from the blood and does not pull it from the tissue/organs.
That could explain people feel great after taking it, and experience continous improvements but usually have to remain on a very low maintenance dose to keep themselves feeling 100 % better. becuase more of the toxins/heavy metals are being pulled from the tissues and organs because of the decrease of metals in the blood and need to be removed as they are released.

But once again, this is ALL just theory...
