Colloidal Mineral Supplements?
Q&A with Bill Harris, M.D.

Q. I have a question about Colloidal mineral supplements. They have every thing from Antimony to Zirconium. some of these are poisons and I'm concerned about the concentration. The dose is 1oz twice a day. What is this equal to 5lbs or 5tons of plant matter.

 



A. Dear Richard,

Without more reference I can't tell you much except that neither of these elements are listed in my biochem and nutrition texts and antimony is only reported to be less toxic than arsenic in my medical dictionary. Sounds like snake oil to me. The minerals you need are usually found in the food you eat. Neither of those are known to be essential nutrients.

Sincerely,

-William Harris, M.D.
