There's not much available out there as compared to, say, colloidal silver, but after taking colloidal gold (CG) for more than a year on a regular basis, I can certainly see differences in myself.
I take at least one ounce per dose, sometimes more if I feel it's needed--unless I forget!
The arthritis discomfort in my hands is no more, and my major joints (elbow, knees, shoulders) "pop" way less.
I use it mainly though for the huge dent it has made in my almost life-long depression. To put it simply, I'm no longer depressed, at all!
It also helps me to maintain a level of calm that I've really come to appreciate and, taken just before bed, it seems to have a positive effect on sleeping.
I also took an IQ test shortly before starting to take CG and another one after about one year of use. Here comes the fun part...my IQ increased about eleven points!
Due to the fact that CG leaves the body after about 30 days, it's important to keep yourself "topped up." That is, once you've taken enough and reached an optimum saturation level for yourself--where you're arthritis isn't troubling you anymore, for instance--you keep taking a maintenance dose to keep it there. That's going to be a different time frame and dose level for everyone. The "forgetting" part I mentioned above comes when I feel pretty good and I forget that I need to keep taking the stuff. That's how well it works for me!
From what we know thus far, CG is totally and completely harmless to any carbon-based living being that has ingested it. There are no known reported side effects of any kind whatsoever. It quickly leaves the body and is a totally non-corrosive metal.
