Iris, you mentioned colloidal minerals in your post. The minerals you find in the Body Balance (mentioned in my post above)are naturally occuring, plant source (organic)minerals. And as you probably know, our bodies absorb plant source much, much better than rock (inorganic) minerals. Sometimes the inorganic minerals build up in our bodies and cause serious illness. Linus Pauling says that we need the organic minerals to help remove the inorganic minerals.
I have tried colloidal minerals. They gave me a headache, same as rock minerals in pill form. The whole food supplement works many times better for me.
