Silver Spring, MD—FDA has senta warning letterto SilveryGuy, a website which encourages the use of colloidal silver for health benefits and pushes the sale thereof through Amazon Associate links, for making COVID-19 claims regarding a product the website was promoting.

The warning letter explains that, as an Amazon associate, the website earns commissions by promoting the sale of certain colloidal silver products through a link on the website. The website makes claims implying that the product can mitigate, prevent, treat, diagnose, or cure COVID-19. FDA’s review notes that this would make the product an unapproved, misbranded new drug, and states: “Causing the introduction or delivery for introduction of these products into interstate commerce is prohibited.” Furthermore, FDA explains that the agency is taking urgent measures to protect consumers from products claiming to prevent, treat, or cure COVID-19.

Some examples of claims made, according to FDA, include:
  • “Colloidal Silver can be atomized by using an ultrasonic humidifier and the resulting atomized ‘fumes’ can be inhaled deep into the lungs, the action of silver colloids getting on the lining of your lungs may prove to inhibit the virus from replicating too quickly.”
  • “Silver particles may reduce your body’s overreaction to the virus. (excessive reaction by a body’s immune system in presence of COVID-19 can cause too much mucous to be created within the lung which basically starts to suffocate a person).”
  • “Good quality colloidal silver solutions contain high amounts of very small colloidal silver nano particles. Which as you’ve read earlier can bind with viruses and coronaviruses and disable them.”
While the above statements come from the SilveryGuy website, FDA also noted a claim on the company’s Facebook page: “What’s your plan if the wuhan #Coronavirus fills up hospitals with patients and you can’t get a bed for treatment? #colloidalsilver may be your last option or your first.

The company has been given 48 hours to send an email to the COVID-19 Task Force describing specific steps it has taken to correct the violations and prevent future violations.
