I took Colloidal Gold and its pretty good although Colloidal doesn't give you the states with Monoatomic does. It is amazing on Rheumatoid Arthritis . People dont take about it here because its a Silver forum also its not easily made because its hard to find the probes and if you do its expensive and most are plated not pure. Also to make true Colloidal Gold you need a machine set up for this as it works at a diffent optimum range (electricity) than Silver to make properly.
