I had done some research and realized that I needed to purchase this form of zinc but it was not that easy to find in Australia. Luckily, I found the product was available from Advanced Bionutritionals . Fortunately, I purchased quite a few bottles so was able to give a bottle to a number of my friends and family to use with their Vitamin C, etc. The tablet does have to be dissolved in your mouth but for good reason and it is very effective. A couple of my friends, who previously were not interested in finding out where to get this type of ionic zinc were also extremely impressed with its effectiveness. I was also really happy to find Advanced Bionutritionals also had written information about this product. My group of friends know the importance of taking good care of their immune systems against present and future attacks and this is one of the products that shines. You would want this in your emergency kit.
