I just found this, verrry interesting...magnesium may even play a role in our evolution!
From Claudia Coleman:
"Magnesium the Unsung Hero "
With the recent emphasis on calcium supplementation to prevent osteoporosis, the importance of magnesium has been overlooked. Calcium and magnesium have a synergistic effect. Neither works well without the other. Not only should these minerals be taken together, they need to be in the proper balance in order to be fully absorbed by the body. Without magnesium, calcium can be deposited in the tissues resulting in conditions, such as, kidney stones. Magnesium plays an additional role unknown to mainstream medicine. It facilitates the transformation of human DNA from carbon-based (3rd dimensional with 2 active strands) to silicon (crystalline)-based (4th and 5th dimensional with multiple active strands). As our frequencies increase, our need for magnesium does also. Magnesium, the unsung hero, may yet take center stage.
