Dr. Joel Wallach, also known as the "Mineral Doctor," is a controversial figure in the field of naturopathic medicine. He created "Youngevity" dietary supplements and claims, in his book "Dead Doctors Don't Lie," that all diseases are due to mineral deficiencies. His theories also posit that death by natural causes is due to mineral deficiencies, and daily supplements of colloidal minerals can extend lifespan significantly.
Wallach holds a Doctorate in Veterinary Medicine from the University of Missouri and a Naturopathic Doctor degree from the National College of Naturopathic Medicine. He is best known for his claims about vitamin and mineral deficiencies and how they affect health. A key component of his claims is that his products, marketed under the Youngevity name, provide the necessary 90 essential ingredients for optimal health.
Many have taken issue with Dr. Wallach's claims, calling Youngevity yet another multi-level marketing scheme with no factual basis is science or support from the medical community. Some have gone so far to question not only his methods and his research in general, but also his credentials as a veterinarian and naturopathic. Dr. Wallace response to such criticisms can be seen on the WallachOnline site, where he is regarded as "A very unique doctor - a doctor who is trained not only in human health, but in animal health as well."
