Colloidal silver's false promises and real dangers

Wellness influencers push colloidal silver as a cure-all, but science says it's useless and can permanently damage your body.

In brief

Wellness influencers push colloidal silver as a cure-all, but science says it's useless and can permanently damage your body. Colloidal silver has no proven health benefits and can cause permanent blue-gray skin discoloration, brain damage, and organ harm. Originally reported by Men's Health.

Influencers push silver as miracle cure

Wellness influencers claim colloidal silver boosts immunity, fights viruses, treats skin conditions, and works as hand sanitizer. Conveniently, they also sell it.

What colloidal silver actually is

Colloidal silver is tiny silver particles suspended in liquid, sold in brownish bottles with droppers. Companies market it as a dietary supplement despite zero scientific support.

Science says it doesn't work

Science says it doesn't work

The National Institutes of Health confirms silver has no known function in the body and is not a nutritionally essential mineral. No scientific evidence supports using it for any disease.

“Scientific evidence doesn't support the use of colloidal silver dietary supplements for any disease or condition.”

It can cause permanent blue skin

Harvard Medical School warns that colloidal silver causes argyria, a condition where silver accumulates in the body and turns skin permanently blue-gray, like a Smurf.

“The skin turns a bluish gray as granules of silver accumulate in the body... Once silver is deposited, there's no way to get it out.”

Other serious health risks

Taking colloidal silver may damage the brain, nerves, and kidneys, cause stomach distress and headaches, and harm the eyes and internal organs.

Don't replace real medicine with it

Don't replace real medicine with it

Using colloidal silver instead of proven treatments or delaying medical care puts your health at serious risk. The NIH warns it should never replace conventional medicine.

The one thing

Colloidal silver has no proven health benefits and can cause permanent blue-gray skin discoloration, brain damage, and organ harm.
