I would be very doubtful of claims of 100ppm. Generally 10-20 ppm should be sufficient (depending on what your taking it for you can vary the amount consumed).
As I understand it angstrom (0.1 nanometers) sized cs particles will be created at the start by any method of electro collodal silver production but you need a constant current method (not constant voltage which is what the 3x9v batteries use) to ensure that the particles don't agglommerate & that larger particles aren't produced when the current through the water increases due to higher concentration of cs (this won't happen in constant current method).I don't think whether the system is DC or AC makes any difference to the particle size, but someone may correct me. Generally I'd say that you're better off making your own cs than buying it from shops/the internet as, ppm aside, a lot of those companies add 'stabilisers' such as animal protein to their cs, & of course you can't really verify any of their claims of ppm of silver being at a certain level (there may be impurities in the silver or water they use) without proper lab tests.

One product gushes about silver colloid having angstrom particle size at a solution of 10 ppm, another proudly offers 100 ppm. What am I shooting for?

I wouldn't want anything over 20 ppm. Any higher and the ions start to combine and get larger.

I haven't gotten a ppm device yet but want to know how to make the ideal solution for internal use without overdoing it. How do I get those wee angstrom sized particles? Is this ideal? Thanks for any input, as ever!

My Silver is 20 ppm. It is clear which indicates the smallest particles possible. When it starts having a yellow color conglomeration has occured. Some smart people like larger particle size because they don't want it to get into the gut where it will possibly kill so called benefitial bacteria.

To make my idea of the best in the whole world.

1. get a Silver Puppy with a stirring system.

2. fill a 16 ounce mason jar with good distilled water

3. use the large stirrer 2 1/2 inches.

4. turn it on auto and come back when its done.

5. let it set for a day in a dark place at room temperature.

6. filter it with a coffee filter.


You can use any current limiting silver maker and get similiar results as long as you have a proper stirring system.
