An important point is that there is a difference between organic and inorganic minerals. It applies to all minerals like calcium, iron, etc.

The inorganic form is found out of the ground and barely usable to the body. The only way to get an organic form is a plant takes the inorganic form up through its roots and metabolizes it where ingesting the plant offers the only way of getting the mineral in its organic, USABLE form.

Inorganic calcium in supplements and "calcium enriched" foods is why people have so many bone problems. It gets sent to the bone and the bone looks at it and says, "It's inorganic, we can't use it, pile it up on the outside of the bone." and you get a sludge like buildup on the outside of the bone leading to typical arthritis symptoms. It's also why people were stoning up their kidneys taking antacids as a calcium supplement. They're just putting in an inorganic source because it's cheaper.

There's a way to magnetize all the inorganic minerals out of your body ~ via distilled water. Everything organic, including distilled water, is negatively charged. Everything inorganic is positively charged. Drink a gallon a day.
