Why did you add nano silver to Earthpaste?

Nano silver has impressive benefits that can support oral health.

Since we first launched Earthpaste, our goal was to keep it as simple, clean, and real as possible, while also staying open to ways to make it even better. We've considered a lot of possible changes over the years, and we finally decided to make one awesome improvement—we added nano silver.

Silver has been used for a variety of medical purposes over the years. It's been used in wound dressings, creams, and coatings for medical devices because of its proven antimicrobial properties. Colloidal silver, in particular, was a popular medical tool for cleaning wounds and handling infections until antibiotics became widespread in the 1940s.

What is colloidal silver, exactly? 

It's a mixture of water and tiny silver particles. Today, colloidal silver is often referred to as nano silver (although, not everything labeled "colloidal silver" qualifies as nano silver). The silver particles in nano silver are especially tiny (less than 100 nm), and their minuscule size gives nano silver bigger benefits.

Studies show, for example, that nano silver's small particle size allow it to penetrate cell membranes more effectively and perform more antimicrobial functions. What does this mean for oral health? Well, bad breath, cavities, and gum infections are all the result of bacteria and other problematic microbes in the mouth. So, a toothpaste with a little nano silver can help your mouth win the daily battle against these critters.

Is silver safe?

Even though we believe that nano silver has some amazing properties for oral health, we also realize it’s one of those ingredients that people have questions about. Maybe you’ve heard stories of the “Blue Man” who drank large amounts of colloidal silver each day. We have too.

But the nano silver in Earthpaste is completely different for a few reasons. First off, the type of colloidal silver we’ve chosen isn’t metabolized by the body and is easily excreted without any residual buildup.

Second, Earthpaste contains a minuscule amount of silver. Each tube of Earthpaste contains 2 parts per million (ppm) of nano silver. That means silver only makes up .0002% of each tube.
