These are tasteless drops that can be added to water or a cold drink, They are supposed to contain a variety of trace minerals that have become more and more depleted in the soil. Physically, I felt no effect.
I have gone long periods without taking this and then if my teeth start to hurt a bit I order some and it fixes the problem. I am a little leery of taking it too much because I have reae colloidal minerals can contain lead depending on where they are sourced. But overall these make my teeth feel better so I presume they are a good product. I don't like the fruity flavored ones. This one is the best.
