I have only used a couple of drops but it is a bit strong for my system, I have IBS, gastritis therefore more sensitive to a number of products. Because it does not agree with my body I feel bad to waste the whole bottle minus two drops, I am selling it for half of that price. I am sure it is very useful to many people because of mineral depleted modern food. And it from a well known supplement company Bodybio. This product has the essential minerals to keep our body working optimally, it replenishes your body with full range of key minerals, it is ionised for maximum absorption and cellular function.
