ZahlerColloidal Silver Liquid - Advanced Immune Support and General Health - 100 PPM Bio-Active Liquid Silver Colloidal Liquid - Kosher Vegetarian Non-GMO Structured Colloidal Silver Water (4 fl oz)

I'm very pleased with this bottle of colloidal silver. It contains a relatively potent 100ppm silver. It's a "clean" product, containing only colloidal silver and purified water. It's made in the USA in a GMP facility. It's packaged in an amber glass bottle (which provides a longer useful shelf life than plastic) which came securely wrapped in layers of bubble wrap. The long shelf life is important to me because colloidal silver is not something to be consumed routinely (the label states "This product is not intended for long-term use") and this 4 ounce bottle will last a long time. I am reserving it for topical treatment of difficult-to-heal wounds, so I will not be consuming this large bottle quickly. The bottle has a stated shelf life of almost 4 years (received 04/2024, expires 01/2028) but properly stored colloidal silver (amber glass, room temperature, away from electronic devices) remains potent for far longer than that.

I have not used colloidal silver before and am eager to try it. It is well known in the homeopathic community as an excellent antimicrobial agent. I got it for to use with my cats - I have read a great deal about the veterinary benefits. I plan on using it for hot spots and general skin maladies, but will likely dilute it a bit to match the concentration used with for sprays..I cannot comment about its efficacy yet, but it is well packaged and a good value.

This colloidal silver is great to have on hand for all kinds of health issues (do your research). It is made in the USA!

I’ve used the popular respected brands of 10 ppm up to 20 ppm colloidal silver products for decades, but never as high as 100 ppm. However, you should be cautiously aware that high ppm does NOT necessarily mean high PSA or bioavailability, and you should take into account the particle size, ideally less than 1nm. The smaller the silver particle size, the greater the surface area for easier absorption as well as excretion so that you don’t end up looking like a Smurf.I don’t ingest colloidal silver because it’s antimicrobial non-selectively, meaning it can potentially kill both harmful and beneficial gut microbiomes. However, nothing works better when used topically for antimicrobial purposes, especially for ear yeast infections in people and dogs. This dark amber liquid has no smell and it contains 500 mcg of colloidal silver suspended in purified water per 1 tsp serving.Because this product doesn’t disclose the important nanometer particle size translating to safety and bioavailability when it comes to colloidal silver, I could only rate it at 3 stars.

I've taken this both orally and topically. This is more potent than others I've taken in the past. One thing to note is that the liquid is amber in color. I think because it is 100ppm of silver. However, it tastes just like distilled water with a hint of metal flavor. If you want to make it last longer, you could dilute it a bit with some more distilled water. This seems to be very high quality silver and I'm a big fan of it and glad to add it to my health regimen.

Review of Zahler's High-Potency Colloidal Silver, Advanced Immune System Support, 4 FL OZ. @ $25.96 at time of order.Likes:High potency. This is 100 ppm (parts per million). Most OTC colloidal silver is normally 30 ppm.Made in the USA!Other than purified water, there is nothing else in this.Price is within reason, especially for this potency.I am a longtime user of colloidal silver for immune system support and believe this is a good product.Dislikes:None so far.

This does not come with a dropper or any way to measure it out. I used a dropper from a previous bottle. It is also a different color than the previous ones that I have used. I have only ever used ones that were a clear liquid with no taste. This does not taste bad at all but I do notice a very mild taste. Besides that it seems to work the same and you get twice as much for a less cost. It also does not say there are any added ingredients so that is great.
