Colloidal silver is a classic

Verified purchase

I do not have an opinion on the colloidal silver of the specific brand, since till now I had been using a home-made cs made by a friend with a cs generator. I find everything else that you buy very expensive, so I would want to invest in a generator. Till then, I bought this...

Thank you for an outstanding product! I only trust the quality when I order thru IHerb. It's scary to order elsewhere since there are so many fake products online. This offered remarkable benefits. I also appreciate the secure and reliable packaging. Thanks iHerb!

I use this in my eyes using a sprayer, or a dropper...it is best to lie back and put drops in the eyes. It is like an eye bath. I also use it in my ears. I pour some into a sprayer or dropper bottle.

Good but not as great as the other brand

Verified purchase

I usually like NOW brand but not for this silver spray. I prefer Sovereign, Silver because it’s a finer mist and not sticky. I’ll keep this to spray on boo boos. I’ll also keep because it’s better than nothing.

A gentle immune support booster that’s easy to use

Verified purchase

I’ve been trying NOW Foods Silver Sol as part of my daily wellness routine, and it’s been a surprisingly helpful addition. The liquid is clear, tasteless, and very easy to take just sprays in the mouth What I like most is how light it feels on the system. I’ve noticed I tend to feel a bit more resilient overall, especially during periods when I usually get run down. It doesn’t cause any stomach discomfort, which is a huge plus for me since I’m careful with anything that might irritate my digestion. The 4 fl oz bottle lasts quite a while, even with daily use, and the dropper-style dispensing makes it convenient to measure. For anyone looking for a mild, easy-to-take immune support supplement, Silver Sol is worth trying. good quality, quality ingredients, size is easy to take, has minerals, package is good, benefit is awesome. composition is quliaty
