Oral colloidal silver is widely promoted on the Internet and elsewhere as a treatment for hundreds of conditions. Unfortunately, there is no evidence that this form of silver provides any medical benefits, and it can lead to an unsightly and permanent discoloration of the skin called argyria.
A typical recommended dose of colloidal silver is 1–4 teaspoons a day, providing 25–100 mcg of silver.
NOTE: We strongly recommend against the use of oral silver products.
Colloidal silver kills microbes on contact, and for this reason, it can be properly described as an antiseptic. Despite widespread claims, however, it is not an antibiotic. The term antibiotic, as most commonly used, indicates a substance that is absorbed after administration and kills germs throughout the body. Colloidal silver does not have this property. When taken by mouth, it may destroy bacteria, fungi, and other organisms in the mouth and digestive tract, but it is not absorbed in sufficient concentrations to kill germs anywhere else. Colloidal silver is, thus, more analogous to bleach than to penicillin. Although both bleach and silver kill the germs that cause sinus infections, you can’t treat a sinus infection by drinking either bleach or silver.
Confusion about the difference between an antibiotic and an antiseptic has led to an enormous number of false claims regarding silver’s benefits. In fact, there is no reliable evidence that use of colloidal silver benefits any health condition.
While oral use of silver is not believed to be toxic, it can cause a serious cosmetic problem known as argyria: gray-black silver deposits that stain the skin and mucous membranes. The effect is unattractive and, to make matters worse, permanent: once it occurs, the discoloration never goes away. A growing number of cases or argyria have been reported in the United States due to the widespread marketing of colloidal silver products. 1-4
