The market’s awash in products claiming to be colloidal silver. Yes, I did say ‘claiming’ to be colloidal silver.True colloidal silver consists of silver nanoparticles. But how can you tell the difference, and is colloidal even safe? Here are 6 facts every silver newbie needs to know about colloidal silver.
6 Must Know Facts About Colloidal Silver
Here are a few must know facts about colloidal silver, with a bit of history thrown in here and there. Use these facts as a guide for choosing the best colloidal silver product, or as a general introduction:
1. The International Space Station Uses Silver to Purify Water
Hospitals have begun using filters containing silver to kill MRSA and other harmful organisms. Even the World Health Organization uses silver and colloidal silver in water filters to disinfect water in developing countries.  The fact is colloidal silver is the least harmful metal to humans and one of the most protective.
2. Silver Kills Harmful Organisms
This is one reason why colloidal silver is used to disinfect water. Historically, silver was used to preserve milk. Settlers would drop a silver dollar in the milk jug to keep it from spoiling. Babies were fed with silver spoons because those that did were generally perceived to be healthier.
3. Greeks and Romans Used Silver to Prevent Food Spoilage
Not only that, colloidal silver was used by physicians in the early part of the twentieth century. They stopped using it with the arrival of antibiotics. That’s when pharmaceutical companies got in on medical care, and that’s when silver and other common remedies became unpopular. They couldn’t be owned or patented, and they wouldn’t be as profitable. But money doesn’t change 2,000 years of facts.
4. How Colloidal Silver Combats Harmful Organisms
A 2013 study of silver nanoparticles, the ones used in true colloidal silver products, examined the effect of the silver against a variety of microorganisms. The researchers found significant effect against common disease-causing bacteria.  Researchers from around the world are currently testing silver nanoparticles for dental use. One study found it helped prevent infection during root canals. 
An Australian study tested silver nanoparticles against bacteria known to worsen rheumatoid arthritis. The study used a silver preparation in a human subject suffering from rheumatoid arthritis. The researchers found it was potent and offered long-lasting protection against irritation associated with the bacteria. 
5. How Does Silver Work Against These Organisms
When a silver atom encounters a bacterial organism, it binds to the cell and the silver gets absorbed through the cell wall. Once inside the organism, it stops certain essential metabolic functions. This supposedly kills the harmful organism. It’s important to note that silver does this to bacteria and other harmful organisms yet it does not have this effect on healthy human cells.
6. Not All Colloidal Silver Really Is
The term colloidal is used to describe two types of silver products: true colloidal silver and ionic silver solutions. The problem with ionic silver is it doesn’t make it through digestion. Colloidal silver is stable. It survives digestion and gets absorbed into the bloodstream. True colloidal silver contains nanoparticles of silver suspended in a pure liquid solution. More than fifty-percent of the silver must be these silver particles. Having these nanoparticles increases the surface area of the silver present and promotes effectiveness.
