I had used Dr Williams advice, enjoyed his newsletter and used the recommended supplements for many years. I have also found that his advice and techniques are many years ahead of the medical research and findings. I stopped using supplements and such but am planning to start again and Dr Williams' products, newsletter and very useful advice are first on my list.
I have consistently seen "new" studies produced by the current medical community that had been observed and recommended by Dr Williams 20 plus years ago (which at the time were admonished by the mainstream medical community), but are now touted by "medical professionals". Dr Williams is real and his advice is sound (in my humble opinion.)
