That's exacly what I discovered researching that Ionic is better than colloidal.
JAB
I don't know if it's better in all cases or not but I have quickly reversed serious illnesses with it time and time again. If you follow a few simple rules it is perfectly safe.
1 only use distilled water, pure silver and nothing else. No additives, silver proteins etc etc.
2 only use a current limiting generator. Silver Puppy is 1 mA.
3 don't go above 20 ppm or you will get larger particles.
