If you are unable to eat milk products or if you are taking a medication such as prednisone, you should definitely take calcium supplements — at least 1000 mg of calcium per day, divided into 2 to 4 doses. Never take more that 500 mg of calcium at one sitting during the day: your body has a hard time utilizing more that 500 mg at a time. And I have heard that among people supplementing with calcium, cranberry juice causes kidney stones. So avoid cranberries.
You might want to take a look at EZorbOnline.com. EZorb is a “new generation” calcium supplement — it has a very high absorption rate. I believe that I can feel the effects of EZorb on my muscle tone and skeletal strength.
The manufacturer states that “EZorb does not need participation of Vitamin D or magnesium for better calcium absorption,” but I still take 1000 IU of Vitamin D every day, and I continue to include old-style calcium-magnesium-zinc supplements in my daily regimen.
Recent research shows that while supplementing with calcium, you should take 1000 IU of Vitamin D every day. The old standard was 400 IU, but now it’s 1000 IU.
