Colloidal Silver Supplements Carry Serious Health Risks
Health authorities say the products have no proven benefit for treating diseases or everyday health problems.
Colloidal silver is sold as an oral supplement, spray, or diffuser product. Supporters promote it for immune support, infection-fighting, skin problems, respiratory concerns, and other conditions. But the NIH says research does not show that these supplements help with any disease or medical condition. Some sellers also present the product as an alternative to ordinary hand-washing, which can expose people to added health risks.
The mixture contains very small silver particles suspended in liquid. Harvard Medical School warns that swallowing it may harm the brain, nerves, and kidneys, and may also lead to stomach upset or headaches. Another concern is argyria, a condition in which silver builds up in the body and changes the skin to a blue-gray color. The eyes and internal organs can also be affected, and the discoloration may remain permanently. Major health organizations have repeatedly cautioned consumers about colloidal silver, despite its continued promotion by wellness influencers and companies selling the products.
