Paez’s form of patient care has made him one of the top chiropractors in the nation due to the advanced technique that he has personally developed over his 16 years in practice. It is common for many of Dr. Paez’s patients to travel extensively from out of state (even out of the country!) just to experience its life changing results.
calcium | Definition, Properties, & Compounds | Britannica
Calcium constitutes 3.64 percent of Earth’s crust and 8 percent of the Moon’s crust, and its cosmic abundance is estimated at 4.9 × 10 4 atoms (on a scale where the abundance of silicon is 10 6 atoms). As calcite (calcium carbonate), it occurs on Earth in limestone, chalk, marble, dolomite, eggshells, pearls, coral, stalactites, stalagmites, and the shells of many marine animals.

What Is Calcium Bicarbonate? | Livestrong
Calcium bicarbonate is not a naturally occurring solid, but it does form in water when calcium, carbonate and bicarbonate ions are dissolved with carbon dioxide. This commonly happens within rivers, streams, lakes and well water because of the water''s exposure to the air and its contact with rocks and sediment that contain minerals and metals.
