@ehBeth,
well, I dont eat the stuff. I just report what they do with ionic silver and how it rally works as a bacteriostat for mold growth on non drinking water. The mold problem on our de humidifiers may be thing of the past. Were going 4 months an no mold .
Your probably drinking trace amounts of silver in your community water supply bcause its often used in combination with Aluminum
granules to help rmove arsenic from public drinking water
Im not aware that theres anyone pushing colloidal (or ionic ) silver for covid19. That would be just like drinking cow urine . In anything at about 10 ppB it starts becoming toxic.
