Anne, I totally agree that minerals are actually more important than vitamins because without minerals, vitamins can't do their job.
And one of the worst sources of calcium is in fact dairy products - because they are not naturally brought to the public, ie they are pasteurised and now all brands of milk appear to be homogenized as well. Milk and dairy products in fact deplete the body of calcium!! The best food sources are dark green leafy vegetables preferably organic. And of course, even organic is not as good at providing all the minerals from the ground as it was years ago because our soils are so depleted. Therefore we all truly do need to take the Ethos OMC to guarantee our mineral intake and help the body to work at its optimal condition. Which reminds me, I need to order another bottle!!
