Colloidal silver has been used for centuries to promote good health and studies continue to also show that colloidal silver outperforms many mainstream methods used against harmful organisms.  With so many cases of antibiotic resistance, it's no wonder why colloidal silver has become extremely popular in recent years. Consumers should know, however, that not all silver products are created equal. Here are 5 things you must know about colloidal silver.
5 Things About Colloidal Silver
1. Parts Per Million (PPM) is Mildly Important
When it comes to colloidal silver, don't get caught up in how many parts per million – or PPM – a solution has. Although it's not a mundane detail, what's really important is the particle size. Smaller particles can move more easily throughout your body and they're more bioavailable. Particle sizes less than .005 microns are ideal. Sometimes this is indicated on the label, sometimes not. One way to tell if silver particles are too large is by examining the color of the solution. A dark or murky-color usually indicates large silver particles and other impurities.
2. Silver Won't Upset Beneficial Intestinal Organisms
A lot of people use silver as defense against harmful organisms. Unlike antibiotics which wipeout both the "bad" and the "good" organisms present in the intestinal tract, silver maintains a balance of intestinal microorganisms. Silver absorbs quickly in the upper GI tract, and little gets through to cause concerns for the beneficial bacteria in the small intestine and colon.
3. Good Colloidal Silver Won't Turn You Blue
Occasionally you may hear of an individual who develops argyria, a condition that develops when silver proteins cause a blueing of the skin. (Do a Google search for Paul Karason.) While this may happen when people use ultra low quality silver solutions, pure hydrosol colloidal silver without additives, proteins, or salts does not cause this condition.  This is why it's imperative to obtain the purest solution available.
4. Purity Matters
Colloidal silver isn't just a mixture of silver and water; it's a solution where the silver particles are suspended in water and have an electrical charge. This type of solution requires ultra pure water. It also requires special equipment necessary to create and maintain a constant charge. Many colloidal silver home brew kits use salts or other compounds during the process to suspend the silver in the solution. Products like this do not offer the same effect as colloidal silver produced with high voltage technology.
5. Only Use the Best Colloidal Silver
Not all colloidal silver products are created alike. First and foremost, choose a product that's been produced using high voltage alternating current technology. This production method requires specialized equipment and produces a silver solution of unparalleled quality and purity compared to low-tech low voltage methods.
