True coloidal silver
This seems good quality coloidal silver. I did a lot of research before buying and a lot of claims from companies selling CS is very confusing and misleading. The bottles with 10ppm or 20ppm are a clear liquid which is ionic silver, not coloidal. Which means they are better used topically on skin or as eye or ear drops. Ionic silver is not good to consume for colds etc as the silver particles are not colloidal which means they are unstable and will not do the job you are hoping for. If you want colloidal silver to consume when ill, you need one like this which is an amber coloured liquid. When it's true colloidal, the silver particles are stable and will travel through your system to kill infection. This took me a lot of searching to get these answers! A good site to look at is silversafety.org. I will definately use this brand again, fast delivery and quality product and they offer true colloidal silver as well as ionic silver sprays.

Everyone should have at home
excellent product from bio energetics . we use this product 20ppm and also the amber formula which is more stronger science has proven then coloidal silver works well at 5ppm or less at 20 ppm its perfect . has no taste or smell it is essentially water . add it to any surface or liquid to disinfect or drink tea spoon everyday 3 times a day . will clean you out and promote good health , kills over 600 types of bacteria , fungai and viruses!!! I know of people using the 20ppm formula as eye drops for conditions including keratoconus . coloidal silver just might be the mirricle thats been kept secret for far too long!!

Brilliant, we have it on subscribe and save
Our little dog has a tear duct and eyelash problem which has the potential to cause eye infections. We use this on the brown areas with cotton wool, and touch wood she hasn't had an infection since. It helps to keep the brown marks down too. Our vet was going to operate on the tear duct, however since using this she changed her mind, and said that she will keep an eye on her instead. It's also great for fungal infections in people, ridding the raised red rash in days.

Maltodextrin in the ingredients
Very disappointed this contains maltodextrin, as a type 1 diabetic maltodextrin gives a really big blood sugar spike worse than sugar, I should have read it properly before ordering

Stops my eczema flare ups in its tracks
I can't believe I forgot to write a review! I love this stuff. I am so glad I took a leap of faith and ordered it. Ordered originally for my animals hoping it would help their immune systems but also tried some myself. I get really bad eczema on my toes so bad that a flare up is so excruciatingly itchy I have made my toes bleed scratching I tried spraying this on one day and it stopped the flare up almost immediately. I won't be without it now.

High quality
Optimised Energetics provides an excellent, fast and friendly service. The quality of their colloidal silver products is very good, be it the lower strength or the Amber. This Enhanced Colloidal Silver Premium Amber helped me a great deal to keep at bay a recurrent Pseudomonas bacterial growth in the bladder area. This was especially invaluable since the antibiotics were not working any more. This is in fact a major component in my case in fighting Pseudomonas bacterial growth. On another occasion, my sister cleared a foot infection – resistant to her antibiotic treatment – by spraying the infected corn with the normal strength - 10 ppm - colloidal silver from Optimised Energetics – in conjunction with taking it orally.

This works!
I work in an office of a school. Over the years, I have noticed that the viruses causing flus and coughs amongst my colleagues were getting harder and harder to get rid off. Some have perpetual coughs and most who get flus and coughs in the autumn during the season change will be sick for months. I caught a terrible cough this year that a colleague had for weeks and using this silver amber I cured myself within days. I swear by this.

喉風邪にと、、、
思ったのだか、効かなかった。 もっと早い段階で飲んでみようと思う。 消臭にも効くなら、スプレーしてみようかな。 身体にも大丈夫なら。 アルコール臭が無いは良いような。
