Colloidal silver is a suspension of the element silver in a solution usually water.
Our proprietary "Star-Rating" system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
3 Stars Reliable and relatively consistent scientific data showing a substantial health benefit.
2 Stars Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
1 Star For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
This supplement has been used in connection with the following health conditions:

Colloidal silver has been used as a topical antiseptic for minor burns for over a century.
Colloidal silver has been used as a topical antiseptic for minor burns for over a century. Internal use of colloidal silver is not recommended for this condition.
How It Works
How to Use It
The typical recommendation is 1 teaspoon per day, with each teaspoon (5 ml) containing 10 parts per million (ppm) of silver or 50 mcg of silver. This amount is in keeping with the average amount of silver consumed from food and water: roughly 350 mcg per day for most people. However, little in known about the relative absorption and toxicity of colloidal silver, compared with that of the silver naturally present in our diet. Because of the lack of long-term safety or efficacy data for colloidal silver, its use cannot be recommended.
Where to Find It
Colloidal silver is sold as a water-based solution.
Silver is not an essential nutrient, and thus no deficiency state exists.
Interactions with Supplements, Foods, & Other Compounds
Interactions with Medicines
When taken in low amounts (e.g., 50 mcg daily), the body appears able to efficiently excrete silver. However, any silver the body is unable to excrete accumulates in body tissues and can result in argyria—the depositing of silver in the internal organs, tissues, and skin.1 Argyria causes the skin to turn gray or bluish gray and to turn dark on exposure to strong sunlight. This discoloration is permanent and there is no known effective treatment for it. In addition to argyria, the intake of very large amounts (far in excess of the amount that causes discoloration of the skin) of silver can cause neurological and organ damage and atherosclerosis .
The estimated amount of silver accumulation over a one-year period that is required to produce argyria is 1 to 6 grams. This amount is very large compared to the 50 mcg typically recommended and consumed by people using OTC colloidal silver products. Using the most conservative figure, 1,000 mg (1 gram) of silver corresponds to the silver content in 100 liters of 10 ppm colloidal silver, 50 liters of 20 PPM colloidal silver, or 33.3 liters of 30 PPM colloidal silver.
