Attention: I'm referring to the home produced product ONLY here!
I take 30ml every morning for exactly that reason, a maintenance thing, been doing this for several years with nil negative effects. I'm not entirely sure if you would need to take it 3 times a day though, could be unnecessary, but then I don't know your circumstances either and I'm not a health advisor, but I'd say go for it if that's the way you want to go. I doubt there would be much silver left in its original form by the time it hits the intestinal flora anyway?
Remember though, I'm referring to the home produced *predominantly Ionic Silver solution*, not the ' Colloidal Silver ' product.
