Colloidal Silver Safety: the Famous Altman Study

Colloidal Silver Safety: the Famous Altman Study In 1999 a researcher named Roger Altman, Eng. Sc. D., took it upon himself to find out the answers to the following two questions:

1.) Where does colloidal silver go when you drink it?

2.) How long does colloidal silver stay in the body after you drink it?

By making careful measurements of the silver that he consumed and the silver that he excreted in urine, feces, hair, nails, sweat, etc. he was able to provide an indication of how well the body uses and eliminates colloidal silver, and of what might constitute “safe” levels of daily consumption so as to avoid silver buildup and potential toxicity in the human body.

This study provides only one set of measurements on one individual, and therefore may not be applicable to other people because of bio-individuality.

Nevertheless, it is fascinating data that has been carefully obtained by a scientifically trained individual using modern analytical tools.

It suggests that a healthy adult can consume approximately 2 mg. of colloidal silver per day without risk, barring problems such as kidney or bowel disease that could inhibit the body’s normal elimination channels.

Since 1 one tsp of 10 ppm colloidal silver contains approximately 50 micrograms of silver, it would take approximately 40 tsp of 10 ppm colloidal silver to make 2 mg.

Who is Dr. Altman To Conduct Such a Study?

Dr. Altman received a Doctorate in Engineering Science (Eng, Sc, D.) from Columbia University in 1971, specializing in process metallurgy.

Since that time he has accumulated about 15 years of R&D experience in metals smelting, and in the process of testing and marketing a device which reduces lead sulfate buildup in lead acid batteries which greatly improves performance and longevity in a wide range of applications.

His long-standing interest in colloidal silver usage led him to use his scientific acumen to study its effects on the human body, which included conducting the above-described study.
