It has a horrible aftertaste

It has a horrible aftertaste that i did not notice with the activz brand.

Silver liquid

I always have silver liquid on hand. It cleared my sinuses, preventing surgery and the use of antibiotics and steroids in 2018. I have not had any sinus infections since then. It even cleared up chronic post nasal drip I had since childhood.

Nano-Silver Review

Excellent experience with Optivida Nano-Silver. Use 2 or 3 times daily. Recommend during the current national crisis for added immunity protection. Have used this product for several years on a regular basis.

Nano Silver

We are all taking it faithfully every day and enjoying that it has no taste. We can't tell if it is working but we believe it is simply because others have testified of that.
