The study included 3-, 7-, and 14-day exposures to American Biotech Labs 10-ppm (15 ml/day) silver solution in a double-blind, placebo controlled, cross-over phase design. Healthy volunteer subjects (36, 12 per each time-exposure), underwent complete metabolic, blood and platelet count, urinalysis tests, sputum hyperresponsiveness and inflammation evaluation, physical examinations, vital sign measurements, and magnetic resonance imaging of the chest and abdomen at baseline and at the end of each phase.
… Keith Moeller, A Managing Director at ABL. “… As a prelim to the study, I volunteered to be checked for silver deposition in my body, after 15+ years of almost daily usage as a supplement to help boost my immune system. No silver residue was found anywhere in my system. We are always working hard to gain knowledge about silver. Because of this, we have now amassed a library of more than 300 major reports, studies and test series, all completed on our nano-silver technology by more than 60 different universities, government/military labs, and private institutions.”
In conclusion the report stated, “The In-vivo oral exposure of a commercial 10-ppm silver nano-particle solution over 3-, 7-, and 14-day exposures does not exhibit clinically important changes in metabolic, hematologic, urine, vital sign changes, physical findings or imaging changes visualized by MRI.” …
Oddly, I cannot find where this study was published nor does the news release, which originated the news item, appear on the company website (as of 4 pm PDT April 23, 2013).
As for the study itself, which researchers ran the study? Was a third party contracted to run it? How did they ensure the study was double-blind? I gather this was not a randomized study.
They state specifically there were no urine changes. If the subjects are eliminating the silver, shouldn’t they be able to see that in the urine? If the silver accumulates in the body, how much is too much? Might it not take longer than 14 days to reach a toxic or dangerous stage?
Moeller’s personal endorsement is not really convincing as one assumes that as managing director of the company he has much to gain by encouraging people to ingest nano silver (ABL sells it as a health supplement). The same holds true regarding this study, which seems to have been run by the company itself.
As it stands, the study seems a bit sketchy but hopefully more details will emerge.
