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.
