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 which 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 tsps. 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.

Meet Steve Barwick


“I'm often asked which colloidal silver generator I recommend. Hands down, I recommend the Micro-Particle Colloidal Silver Generator from my friend Steve Barwick at Silver Edge…I've touted the benefits of pure micro-particle colloidal silver for years to anyone that would listen. Frankly, it's the best way I know to quickly heal cuts, scrapes, sores and burns... treat a host of common illnesses such as colds, flus and sore throats... as well as kill nasty germs on cutting boards, kitchen counters, tooth brushes and even your pet's water bowl. But most importantly is how it can protect you from the deadly pathogen MRSA that has become resistant to almost all known prescription antibiotics. Having a colloidal silver generator as part of your first aid kit just makes sense... especially if you ever find yourself in an emergency with no access to a doctor or hospital.”

-- Michael Cutler, M.D., Editor, Easy Health Options




"I believe the folks at The Silver Edge are the reigning experts on colloidal silver. Nowhere else will you find more accurate information on how to use colloidal silver to protect yourself and your family..."

"Thanks for all your brilliant work to educate people about colloidal silver. It is one of nature’s wonders that helps keep us well."

-- Dr. Keith Scott-Mumby, M.D., MBChB, PhD, author Cancer Research Secrets, Complete Parasites Handbook, and Survive Without Antibiotics




"Hi Steve: I have been a supporter of your work for nearly 15 years, and I have used Colloidal Silver for over 30 years without a single problem, EVER! I have cleared up feline herpes in a cat's eyes, and have prevented infection from countless cuts, post surgery, for other injuries sustained during daily life. It is the safest and best antibiotic, anti-fungal, anti-viral that I have ever used, as opposed to the pricey, worthless, side effects loaded junk that the pharmaceutical companies promote. Read the labels for the antibiotics and other "medications" prescribed by physicians, in good, albeit ignorant, faith, and you will find horror abounding in devastating diseases that they can cause you, including death. So, if anyone has any doubt about using natural Colloidal Silver in place of chemicals, think again. This works, with zero side effects."

-- Dr. Kathleen Olsson Nelson, RN, BA, MA, PhD, PhD, FSNPM, FCH., Clinical Psychologist and Nutritional Consultant




“The bottom line is that for colloidal silver to effectively fight pathogens, you must use micro-particle silver rather than conventional colloidal silver or silver protein products… You can actually make your own micro-particle colloidal silver in your own home. In fact, there’s one colloidal silver generator on the market today -- the Micro-Particle Colloidal Silver Generator from a company called The Silver Edge -- that will make colloidal silver with such uncommonly small silver particles, it requires a multi-million dollar Transmission Electron Microscope operating at 175,000x magnification just to see them. This generator allows you to make the most powerful, and highly bioavailable form of colloidal silver right in your own home. And you can make it for pennies…Having a Micro-Particle Colloidal Silver Generator on hand allows you to protect your entire family – and probably your friends and neighbors as well – for just pennies.”
