Silver, however, doesn't destroy beneficial enzymes because they are very different from the enzymes of single-celled life which silver targets. Silver is nontoxic. Also, colloidal silver doesn't interact or interfere with other medicine being, taken.

Finally, antibiotics only affect bacteria. Silver disables bacteria, viruses, fungi, and all other disease causing organisms.

In prolonged, very heavy doses, some colloidal silver compounds will leave deposits in the heavier skin folds, like the knuckles. This permanent gray coloring of the skin is called Argyria; it is correctable with laser treatment. Argyria is very rare and most often associated with products that use particles of silver which are too large to be flushed out of the body's system naturally. As long as the silver particle size ranges from .005 to .015 microns in diameter, there should be no problem.

How It Works

Silver Shield disables the specific enzyme that many unwanted microorganisms need to metabolize oxygen (breathe). When this enzyme becomes disabled, the microorganisms cannot thrive. NSP Silver Shield with Aqua Sol Technology has been effective against unwanted microorganisms when tested in vitro. Silver Shield is processed by the kidneys and may not affect populations of beneficial bacteria in the colon.

 NSP Silver Shield is safe and effective. It is manufactured using a patented process [licensed for use] (U.S. Patent No. 7,135,195 with strict quality control to verify atomic adsorption. The result is fine, particle-sized colloids with 99% bio availability. Other products tested ranged between 15–65% bio availability. NSP holds exclusive rights on this patented Aqua Sol technology for silver solutions ranging from 16 ppm to 19.9 ppm.

People have long known that silver can be used as a purifying and preserving agent In ancient Greece and Rome, people used silver containers to keep liquids fresh. Early American pioneers put silver dollars in bottles of milk to prevent spoilage. Laboratory workers placed silver dimes in petri dishes to sterilize them.

Today, more than half of the world's airlines use silver water filters because they protect against waterborne diseases like dysentery. NASA uses a silver water-purification system in its space shuttles. Silver is sometimes used in place of chlorine to purify swimming pool water.

And since the turn of the century, people have been using silver in colloidal form as an antibiotic treatment. In fact, until 1938, colloidal silver was considered a mainstream antibiotic treatment. But production was costly with early technology, and so the use of colloidal silver died out. It disables the enzyme that one-celled bacteria, viruses, and fungi need for oxygen metabolism. In the presence of silver, these pathogenic microbes suffocate. In one powerful experiment, 50 gallons of raw sewage were pumped into a pool without any disinfectant. The E. coli count (a standard measure of contamination) was at 7,000 E. coli cells per milliliter of water. The water was exposed to silver electrodes and within three hours, all 50 gallons were free of E. coli.

Colloidal silver is an effective ally in the fight against over 650 disease-causing organisms. These include: bacteria (typhoid, dyptheria, certain types of food poisoning, and pneumonia); viruses (the common cold, influenza, and measles); protozoa (malaria, giardiasis, amebic dysentery); fungi (ringworm, thrush, candida albicans, and athlete's foot); rickettsiae (rocky mountain spotted fever and Q fever); and chlamydiae (infections of the eye, the genitals, and the respiratory system). There is no known microbe that colloidal silver does not destroy.

It turns out that silver ions are very important for the immune system. They supplement and support the T-cells in fighting foreign organisms, almost forming a second immune system. In research done with AIDS, it appears that silver both protects and defends T-cells, and does their work for them. There is also a correlation between occurrence of illness and the level of silver in the body; people who are ill generally register lower levels of silver in their body.

Besides suffocating unwanted invaders, colloidal silver also helps injured tissues grow back. It has been useful in cases of severe burns and broken bones. It reduces scar tissue and helps severe cuts and wounds heal faster. See Before/After Pics 


One thing we keep on hand is Silver Shield. There's a lot of research done on this particular product. Nature's Sunshine Colloidal Silver Shield is the only one on the market that has an EPA designation as non-toxic (EPA# K043106). It also has a US patent (7,135,195) for it's safe technology.
