How to Tell Quality of Colloidal Silver

Quality of Colloidal SilverWe often get similar questions about the quality of colloidal silver. Which is better, silver ions or particles? Is 500ppm better than 15ppm? How can I tell if colloidal silver is good or not? I’d like to help clarify the answer to these questions.

Ions vs. Particles

Mountain Well-Being Colloidal Silver is made using low voltage direct current (LVDC) and contains 80-85% silver ions and 15-20% silver particles, giving the user the best of both worlds. Some companies bash silver ions and try to claim that only silver particles are effective, which is absolutely not true. Both ions and particles are useful, however, silver ions work much more quickly and powerfully. But silver particles tend to have a longer lasting effect in the body because they work by releasing silver ions. If the particles did not release silver ions, they would be ineffective.

In July, 2012, “New research by Rice University found that silver ions, not the particles themselves, are toxic to bacteria.” That is exactly what every book on colloidal silver that I own states very clearly. So while in liquid form, silver ions are much more effective than particles, however both have benefits. Once a solution containing silver ions dries, it is no longer effective, which is why we make the colloidal silver for our Soothing Silver Gel – Mountain Well-Being with high voltage AC current (HVAC). This produces a mostly-particulate colloidal silver so that once the silver gel dries on your skin, there remains a thin layer of silver particles that are able to release silver ions for the benefit of your cut, scrape, burn, rash, etc.

Another benefit of LVDC produced colloidal silver is that the silver particles and ions have a natural (positive and negative) charge just like our bodies, and are absorbed and utilized more effectively than the artificial charge of HVAC produced particles.

Color and Clarity

The best colloidal silver will always be crystal clear for the following reasons. We just learned why silver ions are more effective than silver particles, so any good product will contain a decent portion of ions. And an ion is an atom that’s missing an electron, and you can’t get any smaller than an atom. In fact, ions are so small that they are completely dissolved into the water and cause no discoloration. Silver particles should be extremely small in size which will not reflect any spectrum of light, therefore keeping the liquid clear. Mountain Well-Being Colloidal Silver particles average about 1 nanometer, and the solution is always crystal clear.

Any time you see colloidal silver with color, usually either yellow or brown, you know at least one of two things: 1) either the particles are large enough to begin reflecting the light spectrum, or 2) there is some sort of additive. Neither of these cases are good, and I would caution against ingesting colloidal silver that is not clear. The colored varieties are most likely safe for external use, so if you have some you don’t necessarily have to waste it.

Parts Per Million (PPM)

Some companies will try to convince you that only colloidal silver in the hundreds of ppms will be effective. Again, absolutely not true when talking about a high quality product made with the preferred LVDC method. The industry standard is 10ppm for a reason. At this concentration, colloidal silver made correctly is both safe and effective. Once a solution becomes saturated with enough silver, smaller particles will tend to link together forming larger particles which are less effective and less safe. This process is called agglomeration and begins not far above 20ppm no matter how good the technology. Mountain Well-Being produces 15ppm colloidal silver, which is 1.5x stronger than the industry standard, because we use state-of-the-art equipment that is able to keep the particle size extremely small at this level.

Pretty much all of the brands that advertise 100’s of ppms, or even 1000’s, are making a product known as mild silver protein (MSP). These products are NOT safe and can definitely cause argyria, a permanent skin discoloration! To easily test for a MSP, shake the bottle vigorously and if foam persists (as if it looks like soapy bubbles are on the surface of the liquid), you have a MSP. Do not ingest!

The protein is usually gelatin or another animal product, so they are not vegan products. An analogy would be like tying a balloon to a brick to keep it from sinking. The particles of silver are so enormous in MSP that they would sink without the floatation assistance from the protein. But this protein coats the surface of the silver particles, keeping them from coming in contact with what they’re supposed to be targeting! There have actually been bacteria found living inside bottles of MSP because of this!


The best colloidal silver contains a nice mixture of both silver ions and silver particles, produced using LVDC, with the smallest possible particle size and a crystal clear liquid, in a concentration less than 20ppm to ensure the particles remain as small as possible, and without any additives. Mountain Well-Being is committed to making the finest colloidal solutions on the market. All batches are structured and energized using the latest techniques available. 100% satisfaction guaranteed!

    i have been reading about the best and true colloidal silvers and they all say it should never be clear in colour and should not have silver ions only silver particles. You seem to be the only one saying it should be clear. Im not sure thats true if everyone else is saying the opposite

      Hi Lisa,
      Thanks for your email. Your question is pretty common, because there is a lot of misinformation in the colloidal silver industry. First off, all colloidal silver contains a mixture of both ions and particles. Some CS has mostly ions and some has mostly particles. All the books I have on colloidal silver all say that it should be clear in color. When colloidal silver is darker in color, it’s because either the particle size is getting larger, or it contains some kind of additive(s), neither which is good. Colloidal silver with the smallest particles of silver is clear.

      The largest colloidal silver producer in the USA is Natural Immunogenics. They produce Sovereign Silver, which is clear and contains over 90% silver ions. The largest colloidal silver producer in Europe is Ion-Silver in Sweden, and they also produce a clear and mostly ionic product. Almost all homemade CS contains mostly silver ions. There are hundreds of scientific studies that prove beyond any doubt that silver IONS are what give silver it’s antimicrobial properties. If this were not true, all the homemade users and users of the most popular CS brands would not be reporting such great results. Silver particles are good too, but only because they release silver ions!

      Particle size is the most important factor for the efficacy and safety of colloidal silver. A silver ion is the size of a single atom, and you cannot get any smaller than that. So, it’s certainly not everyone saying that CS shouldn’t be clear. It’s only the handful of people that sell mostly particulate silver that are spreading disinformation to sell more of their product. Please do your research on the germ killing powers of silver ions. Let me know if you have any more questions.

      Be well,

    I have been making my own CS for a couple of weeks now, but after reading all this stuff about COLOR, I get a little confused about a couple of things.

    I use 3 9V batteries connected to .999 silver electrodes from a bullion bar that I cut in half inside an 8 glass. After about 20 minutes of run time I can observe a light brown streamer emanating from one of the electrodes. Are these streamers ions or non-ionic silver particles?

    The longer I allow the unit to run, the darker the distilled water becomes, I may add some CS from a previous batch for seeding but other than that, I put nothing else in the DS Water. So how do I know when to STOP to assure I have the most useful QUANTITY of ions in the water before it starts turning color & changing to yellow & thus increasing particle size?

      Hi Paul,
      It’s very difficult to make high quality CS using 9v batteries. I started that way but soon realized there is no control over the particle size. The longer you run it, the larger the particles get. If you can see the particles with your naked eyes, then they are WAY too large to ingest. Ions are always invisible and so are nanoparticles. I would use this CS only for topical use. You need a generator with constant current technology to produce high quality CS. And your water needs to be pure, often times distilled is not pure enough. The water should be constantly stirred during production. If you want to use the 9v CS internally, so production long before you ever see anything. Get a PWT meter so you have some idea of water purity and CS strength.

    Another question for Jonathan and to make sure I understand about clarity of water. So, what you are saying is the smaller particle size particles should not show up using a red/green laser lights trying to obtain the Tyndall effect, correct? Therefore, we could have 10-20 ppm of colloidal and ionic silver solution and the solution will have no Tyndall effect (it will appear as distilled water) if the particle size is very fine. Is that correct?

    And with that said, this is the highest quality nano colloidal silver solution we are after? Correct?

      Hi Bob,
      Particle size is the most important factor in determining the efficacy and safety of colloidal silver. The smaller the better. A silver ion is the size of a single atom and that’s as small as you can get. Silver ions are completely dissolved into the water and don’t produce a Tyndall effect. Silver particles that are extremely small (in the <1-10 nanometer range) won't show a strong Tyndall effect, but any particles will show at least a slight Tyndall effect. You will probably have to use the laser in a dark room to be able to see it. Very fine particles don't show a strong enough tyndall effect to be seen in a lit room. This is the highest quality colloidal silver: one that contains both ions and particle and where the particles are so small that the Tyndall effect is faint. I hope this helps you.

    Hi Jonathan, I have a glass bottle of colloidal silver I used to take regularly but has been sitting in the back of my kitchen cupboard for a few years. It has a used by date of 2016, but it is still crystal clear and I took a shot this morning and it does not taste tainted or anything, slightly bitter aftertaste if anything but I think that’s probably normal? I feel it’s ok still to use but would love your opinion please.
    Also I have a father-in-law having chemotherapy and experiencing some problems with infection, one in the lungs, one in the arm at the entry point of a blood transfusion. Is there any reason he should not ingest colloidal silver while on chemo? Any other suggestions around this? Thanks so much.

      Hi Michelle,
      If you store CS properly, which means at room temp, out of direct light, and away from strong electro-magnetic fields, it should last at least a decade or even much longer. Since it looks clear and still has the bitter (metallic) aftertaste, you should be perfectly fine.

      I don’t see any reason a person couldn’t use CS while on chemo, but of course I’m not a doctor and I must cover myself by recommending that you consult a healthcare professional for your question. For lung infections, I personally would not want to be without my nebulizer and CS. For topical wounds or infections, again, I would not want to be without CS or a CS gel. When using liquid CS topically, it works best if you can keep the CS moist against the skin by using a bandage or band-aid.

      I hope this helps you. Let me know if you have any more questions.

      Be well,
