Glad I bought this Review by

I started taking colloidal silver about a year ago on the recommendation of a friend who took it instead of getting a few basic immunisations for travel. I haven't had a cold or sore throat since. And I also didn't take malaria tablets during my two months in asia and I was fine.

Excellent Product Review by

We use this for most ailments, from sore ears and sore throats to mouth ulcers. We have found it to be extremely effective. No antibiotics since we started using silver!!

Excellent product Review by

I have not caught any colds this year, which is incredible as I work with the public. So many people have been sick and so far nothing. I really like this product. It is well priced and doesn't leave a horrible after taste, Thanks

Excellent Immune support Review by

After picking up bug after bug after bug I took Colloidal Silver for 4 days and found it gave my system the boost it needed to get me back on track. priced at $15.00 for the 500ml bottle, it is quarter of the price that the health shops sell it for.

We've happily used this product for years and found it to be effective, especially with sore throats. However the new label doesn't seem to have directions for dose/use on it.
