A good product, the small spray bottle is a very useful addition. has a mild metallic taste
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. 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)

Works like a charm for H. Pylori infection.
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.

Great for general health
I will always recommend Colloidal Silver for any bacterial viruses and for general health. A shot or two is enough.

Brilliant stuff!
I'd heard about colloidal silver for a few years but it wasn't until January that I decided to bite the bullet and make the purchase. I'm really glad I did. So far I've used it successfully to treat a sty, the symptoms of which disappeared completely within two to three days, and the pain eased within a couple of hours of first administering it. I'm also now using it for an allergy I've had for many years. After less than a week of taking 10ml morning and night and using it as a nasal spray, my nasal passages are the clearest I can remember them being in a very long time. I'm also using it as a hand sanitiser in a little spray bottle. Excellent product, I would highly recommend it. Seems to work at its best when you drink lots of water throughout the day.

Great Antibacterial product to use
I am using this product to help clean my hands when I go out, I mix it with Oil Lavender and spray 3 x onto my hands regularly. I also use 5ml a day and no more, by mixing into a 500ml glass bottle with water, 5g Ascorbic Acid (Vitamin C) and sugar free fruit flavored cordial to keep my immune system up, and a good Probiotic in the evening, I sip it during the day so far so good. Great company to deal with also and a high quality product. Time will tell if the above will help protect me during the Covid-19 outbreak, stay safe all...

Acheter pour mes problèmes de peau (psoriasis) et pour mon chien qui se gratte beaucoup. Pour mon chien, c'est un vrai miracle, j'en mets pas tous les jours (uniquement quand elle se gratte de trop). Pour moi, je le mets une fois par jour sur mes plaques et ça apaise les traitements.

Das Kolloidale Silber kam sauber und gut verpackt an und dank dem kleinen beigefügtem Messbecher lässt es sich ganz einfach in die kleine Sprühflasche umfüllen! Ich habe es schon öfters bestellt und werde auch immer wieder bestellen! Top Qualität!

We’ve used this product for years now. Helps with things like throat infections and tooth decay especially until you can get seen. You get a little refillable spray bottle which is really handy for your handbag / being out the house. We like the glass bottles. You can easily see how much is left. Probably the 10th bottle we’ve purchased now - great price and quality

Ik heb de afgelopen jaren al minstens 6 merken uitgeprobeerd ivm met steeds terugkerende blaasontsteking. Was klaar met zo vaak antibiotica slikken, waar de bacteriën steeds resistent tegen worden. Maar dit merk zilverwater werkt echt het beste van allemaal. Binnen een halve dag zijn de ergste verschijnselen al zo goed als weg. Ook bij verkoudheid, griep, enz. Ik ben uitgeëxperimenteerd. Voortaan alleen nog dit merk. Is ook nog eens de goedkoopste. Wel de gebruiksaanwijzing goed lezen.

Se lo he comprado a mi madre que tiene 84 años, con un estreñimiento crónico y nada mas tomar la primera dosis a las pocas horas su intestino empezó ha funcionar. Para mí, es milagroso! no le faltará nunca, de eso estoy segura. Y desde luego de Institut Katharos sin duda. Me da confianza, va además con envase opaco y en su caja .Precio razonable y entrega inmediata. Le doy en 10!!
