I always used the colloidal silver and I can confirm this one is the best I have tried in the UK. Also, I always prefer the glass bottles and I really suggest using always the glass ones!
The bottles are always well packaged and arrive quickly . Good communication from company as well . A very efficient company that provide a fantastic product and service too .
