Caltrate Calcium Reviews of supplement. Are these good for those wanting to build stronger bones? for those with Osteopenia or Osteoporosis?
Scientific studies have shown the importance of calcium/Vitamin D supplements in slowing bone loss. Recent studies also show the importance of taking Vitamin D along with any calcium supplement. A number of manufacturers now include Vitamin D in their products and some prescription drugs include Vitamin D recommendations with their information packs.
But the big question for those of us with Osteopenia is: Which of the many calcium supplements on the market is best for bone building?. Many manufacturers make big claims for their products. This page give you an unbiased review: Is Caltrate Calcium supplement the one?
The National Center for Biotechnology Information in the United States published ABSTRACTS (and sometimes the full text) of all scientific studies found in medical academic journals. If you want to know what scientists have to say, this is first place to go.
When I searched NCBI for some scientific studies Clatrate Calcium, I was surprised to find only one article and it was published in the Eur. Journal Clinical Nutrition back in 1991.
The study was authored by researchers at the Division of Clinical Chemistry, Royal Adelaide Hospital, South Australia and its title was “The Effect of three different calcium preparations on urinary calcium and hydroxyproline excretion in postmenopausal osteoporotic women.”. The three brands were: Sandocal, Calsup and Caltrate.
Their conclusion? There was NO DIFFERENCE IN THE EFFECTIVENESS of the three brands of calcium supplements tested.
If you want to read their research conclusions for yourself, here they are:

“Some authors have claimed that 'solubilized' calcium preparations are better absorbed than calcium carbonate, while others have reported that all forms are equally well absorbed. We measured radiocalcium absorption in 35 postmenopausal osteoporotic women and then gave them on three successive evenings, in random order, three different proprietary calcium preparations (Sandocal containing 1 g of effervescent calcium, Calsup containing 1 g of calcium as the carbonate, and Caltrate containing 1.2 g of calcium as the carbonate).
The daily urinary calcium excretion rose significantly and similarly on all three supplements and was greater in the high calcium absorbers than the low calcium absorbers. The fasting urinary hydroxyproline excretion was significantly decreased the morning after administration of each preparation, and one-way analysis of variance showed no significant difference between the days of administration or the type of supplement.
The decrease was greater for high absorbers than for low absorbers on all three supplements but the differences did not reach statistical significance. By 36 hours after the last calcium supplement the urinary hydroxyproline had returned to baseline. The response of hydroxyproline excretion (and by implication bone resorption) appears to be rapid in onset and short lived. Strict compliance is therefore important in patients on calcium therapy.”
Some forms of calcium have been shown to be better absorbed. And these claims have been verified in scientific studies. AAACa, sold under the brand name of Advacal is one such form of Calcium.
