I have just the opposite experience. In the late 80’s Wallach tied in with a MLM guy in Santa Cruz where I lived at the time. The MLM guy sold us on the program along with a large number of others. We all went all in. After about six months the MLM guy stroked out and one of the other committed people had a serious heart attack at the ripe old age of 32. I stopped the mineral goo and went what is now called keto diet and improved my medical situation with that. Glad you had results that were positive but Wallach fits the classic definition of a quack.

And at issue is the science. He has been sued by Big Pharma no less than 11 times....and he was won every single case based off of science. No one has that record.
I have seen the websites that criticize him. I can tell you my former career as an intelligence specialist served me well to sift through bias and unfounded accusations. Not once do they attack the science and they have no answer for the legions of people he has cured (and Wallach cannot use the "cure" word, even though he does. He uses "supports health."
They certainly do not touch his credentials. Quacks don't have works that are inducted into the Smithsonian Institute. He teaches doctors (MDs) and nurses, not the other way around.
Sorry you had a bad experience, but it wasn't from his product. Just bad timing-- they were not reached in time to repair the damage from the standard American diet (SAD).
NIH and Big Pharma loath him. He is a threat because he cures people. The science is unassailable and it is not a hidden issue-- he is published. Quacks don't do that. If you can come up with a declarative sentence where he is wrong, I'd love to examine it.
On the contrary, when friends, family and co-workers get the flu, I get rid of it in about 10 hours, with recovery results in about 1 hour. I have GROWN CARTILAGE in my joints after punishing them during a 20 year Marine Corps career. Go find a MD that can do that. Not one, and I had the Navy's best orthopedic surgeon in 2004 at Bethesda Naval Medical Center. I was forced into retirement in 2005 while I was on the selection board for Master Sergeant--which would have kept me in for another 3 years.
It's all about the science. I don't do emotion or logic fallacies. Because of Dr Wallach, I walked away from degenerative disk disease, plantar fasciitis, carpal tunnel, allergies, arthritis, high cholesterol, gout and kidney disease. I take zero prescription drugs as a retiree and I do not get sick, particularly the flu since 2012.
To this day, I draw ZERO veteran's disability because I screwed up and cured myself of all maladies. I could have received at least 50% disability paid for by the taxpayers for the rest of my life.
