somebody asked about dosages for ingesting the silver and it got me curious... for those interested...
"Safe usage with the 12-for-25™ rule
The 12-for-25™ rule is a formula devised by Jay Newman, president and CEO of Invision International Health Solutions, manufacturers of Silver 100™ Ionic Silver Complex, a dietary supplement containing silver.
It provides a simple method for determining how many drops an individual can take per day of any given silver product to be at or below 25% of the RfD guideline.
Note that in the formulas below, the "·" symbol indicates "multiplied by."
The formula is:
12 • pounds ÷ ppm = drops
What that says in plain English is the following:
12, multiplied by the number of pounds of body weight of the person, divided by the ppm of the product, equals the number of drops of the product that it is safe for the person to take per day—because it will result in an amount of silver intake that is equal to about 25% of the amount of silver the EPA suggests as the safety guideline (RfD) for the upper limit of daily silver intake.
The 12-for-25™ rule can be applied to the ingestion of any product that contains silver, regardless of whether it is commercially produced or made at home and regardless of whether the product is called ionic or colloidal or nano or anything else.
It maintains that a basic rule of thumb that's probably more than safe is that if your daily intake of silver from a dietary supplement is less than about 25% of the silver that the EPA recommends as safe for daily oral ingestion of silver, you're probably fine. This is like saying that if the EPA's suggested limits on silver concentration in drinking water are exactly met, and a person drinks a liter of water per 77 pounds of body weight, obtaining the equivalent of 25% of that much silver with a dietary supplement will result in about the same amount of silver as their drinking an additional 25% of a liter of their water per 77 pounds of body weight.
All things considered, the 12-for-25™ rule should obviously be a very reliable safety guideline."
