To be honest,I would love to make my own silver, gold, lotions, body butter, but there just isn't enough time in the day! :)
Besides I think purifying water seems like a complicated process and rather not turn blue by ingesting silver proteins via tap or filtered water, therefore needing YAG lsser treatments to return my skin back to normal.
I rather go with a trusted brand with regular testing of its products.
It'll be nice if someone made a spreadsheet on Colloidal Silver by brand, price, strength, and whether it is nanoparticle, true silver, or ionic, protein and posted it here! Any volunteers?
