With chelation, there has been evidence of improvement in skin color, arterial pulsation and temperature in the feet, ability to walk long distances comfortably, brain function, and muscular coordination, not to mention relief from extreme discomfort in the heart.
Chelation is based on how metals bind to organic molecules.
Initially used in industrial applications, it was useful for electroplating and separating specific metals. It wasn't long before chelation was found also to benefit any condition caused or aggravated by lack of blood to organs or tissues. Soon, an intravenous chelation solution containing a substance called EDTA became the preferred approach to relieve lead poisoning in children and adults. It still is today. This early form of chelation quickly showed its extraordinary benefits beyond lead detoxification.
