Toxic metals serve no function in the human body. If they accumulate enough, they wreak havoc and can cause all kinds of illness and diseases. Other metals which are essential to human function can become toxic if they accumulate in large amounts; examples include iron and copper. Chelation therapy can restore your QUALITY of life. Be warned though — not all chelation therapy is equal. Dr Maulfair is a leader in chelation therapy and has been successfully treating patients for over 30 years.
