For example, one manufacturer claims that ''the darker the solution, the more potent the concentration of silver'', implying that their dark brown, high ppm product is what you should buy.
Much more often than not, these products do not conform to their labeled claims. (The 500 ppm product noted above actually tested at 420 ppm in our lab). And although it contains a large quantity of silver particles smaller than most, it is also a hybrid protein solution as well as colloid.
Such ''advice'' is not only spurious but dangerous since any quantity over 350 micrograms (mcg) per day exceeds EPA standards for silver in drinking water. The same manufacturer recommends a dose of 1/2 tsp. per day of its 500 ppm colloidal silver, or 1250 mcg; over three times the maximum reference dose!
