HI, sorry, just spotted this one...
There are many reasons why I have concerns about extra SUPPLEMENTAL calcium for her-2 folks... I have no issues with normal calcium such as that from foods. If you want to build your bones though..it is magnesium that you need to be taking and not calcium...I do not know why calcium has received so much Popular press...but as I am fond of saying NO NEED TO TAKE my word for it...anyone concerned about the calcium issue..should google CALCIUM MAGNESIUM homeostasis...to understand what is really going on.
In a nutshell...the problem is absorption...no matter HOW MUCH SUPPLEMENTAL CALCIUM YOU INGEST...in the gut your body will only absorb an amount of calcium that is equal to the per cent of the magnesium in your system at the time. For instance...if you have 25mg of mag in your gut and ingest 1,000mg of supplemental calcium...you will absorb 25 mg of mag and 25mg of calcium (this is because the heart muscle needs the calcium to contract and the magnesium to relax--it is an evolutionary system that has been conserved since hearts evolved ...).
If you are young and healthy with superb bowel and kidney function, the extra 975 mg of calc won't really harm you and will be pooped or pee'ed out..to be blunt...smile...HOWEVER...as the typical American diet is notoriously poor in magnesium...if over time, you keep ingesting such a disproportionate amount of calcium to magnesium..real trouble will start. First, it will become harder and harder for your kidneys and bowels to rid the body of the excess supplemental calcium...causing lots of undue wear and tear on these vital organs...eventually, over time, the body will not be able to rid itself of ALL the excess calcium so guess what??? your body will start to store it in the the WORST of places..your bowels will become like cement..your joints will harden and calcify and then, your veins will start filling up with what is known in the trade as "calc plaque" which forms an ideal structure for bacterial biofilm to cling to which will lead to high blood pressure, heart attack and stroke and not make any "cancer situation" better than is for certain.
Read the data for yourself. Why the doctors don't understand how the calcium mag homeostasis works anymore is beyond me....sigh... Remember, it is YOUR body and YOUR life...so take good care, one and all, Gina (

PS...My father DIED because of "calc plaque"...went in for quad bypass surgery and the docs were unable to do even 1 bypass as the arteries in the heart were COMPLETELY calcified so the docs sewed him back up and told us that he would continue to have heart attacks and strokes until...he died the day before my 3rd chemo.
