Natural Clinoptilolite is the safest and most commonly used form of zeolite for health and healing, as it has the unique ability to absorb and remove large amounts of heavy metals, volatile organics and radioactive particles with no side effects. It does this without removing the needed metals and minerals like iron or calcium, which is just astounding. Clinoptilolite Zeolite has a net negative charge as well as a unique cage like structure that captures the small highly charged toxins like mercury or strontium-90 and can quickly remove them from the body. Once heavy metals have been captured by the negative charge of the zeolite, they are effectively neutralized and can be removed from the body without damaging the surrounding tissue. The best part is that it can do this in 5-7 hours. Clinoptilolite is incredibly fast acting and is removed from the body in under 7 hours. NCD2 (Natural Cellular Defence) clinoptilolite zeolite is absorbed almost immediately into the blood and travels throughout the body absorbing toxins like a magnet. NCD2 is able to do this as the zeolite is properly micronized giving it the largest surface area possible.
