BRENDAN BRAZIER ON CALCIUM

The blood will always remain neutral – this is imperative for survival – so if the body is consistently fed acid-forming, denatured foods and supplements, or encounters stress from other sources, it must take measures to ensure a neutral blood pH is maintained. In doing so, the body pulls calcium, the mineral is our body that is most alkaline, from the bones. Over time, the bones weaken as a result of this survival mechanism. The conventional way of treating low calcium levels and osteoporosis is to “take” more calcium, usually in the form of supplements. The calcium in tablets is usually derived from oyster shells, bovine bone meal, coral or dolomite (a type of rock), all of which are extremely hard and unnatural for the body to assimilate – they are not food. (…) the body must work very hard to get calcium from these sources.

the body is under great stress to recover from workouts, rebuild cells, and keep the immune system strong, and the last thing it needs is another job. Most people take too many supplements in an effort to speed regeneration. Often they just interfere with that process, prolonging the time needed for complete recovery.

Athletes and people living in a warm climate will need extra amounts of dietary calcium since it is excreted in sweat.
