It's got a slightly more metallic test then some other brands ive used before, but its very mild. i appreciate the glass bottle. the spray bottle is very handy. ive used it on rashes, cuts and burns, as supposedly it helps heal faster, but ive never measured that. other ways ive usually used it, is to hold a drop/ spray under the tongue, and spray into my ear and nose when ive had a cold and am congested, i feel it also helps reduce the time I'm ill. my understanding is the silver ions, are spikey and puncture the bad stuff- but im not a scientist, i just like the idea of simple natural products. (other natural stuff I enjoy includes oregano oil, oysters for bioavailable zinc, apple cider vinegar, tamarind using glass food storage, and grounding feet in damp earth alongside natural sunlight. It's the simple hippie things but they seem to add up to my overall sense of well-being so ill keep using them) Review: Great product - Fantastic congratulations and a great product. ## Features - ●●● POWERFUL COLLOIDAL SILVER ●●● Just two ingredients.

Size I'd a human cell?** A: The ionic silver has nanoparticles 0.15 nanometres and the Colloidal 1-5 nanometres. The smaller particles are more bioavailable and my understanding is they do pass over the human/animal cell barrier. **Q: Can u ingest this and use it as a cleanse** A: Yes definitely as me and the dogs use it, did you read the ebook sent to your email? **Q: Has anyone got the correct link to the ebook the one I got in the little leaflet with this isn’t working** A: I didnt get an e mail and the address on leaflet doesnt work. I know they used this before antibiotics were invented in the first world war! ## Customer Reviews ### ⭐⭐⭐⭐⭐ A good product, the small spray bottle is a very useful addition. has a mild metallic taste *by T***Y on 3 February 2024* This is the 2nd time ive purchased this product and i haven't turned blue yet drinking it... regardless id rather drink (intermittently) a lab-tested product then risk the home made stuff to avoid the potential side effects I've heard about, so this fits the bill nicely.

Pylori infection. *by H***L on 2 April 2021* Basic review: I used this product to treat what I suspected was an Helicobacter pylori infection. Helicobacter pylori is a bacteria which is well known for causing severe stomach conditions such as ulcers, severe acid reflux, bloating etc... This product cleared my problem within 2 doses. I took a total of 7 doses to be sure. Extended review: I began struggling with severe acid reflux, especially at night, that was persistent for about 2 or 3 days. Symptoms were bloating, and severe acid reflux that created a kind of cough, and I needed to consistently clear my throat of this which felt like it sat in a pocket at the base of my throat. My stomach also just felt like it was constantly filled with an acid gas cloud. You feel like you need to burp but cant, and if you manage it then comes with massive amount of acid as if you're throwing up. Even drinking water was hell, and a good nights sleep began to elude me completely. So I contacted my G.P. who prescribed a proton pump inhibitor known as Omeprazole. All it does is decrease the amount of stomach acid, that's it which I found annoying but thought fair enough, Doctors know what they are doing. It didn't really. I proceeded with this prescription for a week to give it a proper opportunity to work. It did not, it was a week of hell. Fed up with the G.P. I suspected an H. Pylori infection. You can get it from all kinds of things or surfaces that aren't washed properly. Just one mistake washing vegetables or contact with one unclean miscreant who cannot be bothered to wash their hands and boom, that's all it takes. Why this is not the first thing doctors don't suspect is beyond me and the damned G.P.'s in the U.K. basically need to be begged to use their brain cells. Suspecting that it was an infection, and wanting to avoid having to deal with a G.P. and avoid then taking antibiotics which is basically what they would have prescribed me had I eventually convinced them to try something else. I then purchased this Colloidal silver. I arrived the next day. Perfect. well packaged. I felt a significant difference upon consuming the first 10ml dose. I took 2 doses per day for the first 2 days. By the 2nd day I was completely symptom free. I proceeded to take it for 5 days at the recommended once per day. The damage from the acid took about 1 week to get better. That is the cough, the phlegm etc... Cured. I have no idea if it was actually H. Pylori as I never had any test to confirm. But, I suspected bacteria, took something that kills bacteria, and now I am cured, what more do you need? Why this is not the first recommendation by the medical establishment is beyond me. The side effects of omeprazole is staggering, you shouldn't touch it unless you absolutely have to. ## Frequently Bought Together - Premium Colloidal Silver 40ppm 1000mL ● Optimal Concentration Formula, Smaller Particles, Better Results ● Laboratory Certified ● Liquid Silver Made in EU ● Free Spray Bottle to Fill & Ebook Included - Nature's Gold Organic Klamath Lake Blue Green Algae Supplement 500mg 60 Tablets - 130 mg Carvacrol - 150 mg Oregano Oil per Softgel.
