AlgaeCal Studies: Calcium Supplement

 AlgaeCal Studies As you know, anyone can claim anything and in the world of calcium supplements there are many claims being made.

One of the things I have dedicated myself to do on this Osteopenia3 web site, is provide you with scientific studies for any and all topics discussed. So it was that I sought out published  studies about AlgaeCal.

The manufacture of this supplement lists a number of testimonials on their web site. And although testimonials are interesting and are known to be effective marketing tools, we need to remember that ‘proof is in the clinical test results’.

The company also emphasize that there have been studies done in different countries. But what you want to find out is exactly what was studied and what the exact results were.


I have found one study of the bioavailability of this supplement. The study compared the product with Caltrate 600, a popular calcium supplement that has been rather widely advertised in the media. In this study AlgaeCal’s bioavailability was found to be 75% while Caltrate 600 was 69%. This is an impressive result.

The second of AlgaeCal Studies I found is listed in PubMed, a data base of all published scientific studies in medicine.

The title of the study is: The Comparaitve Effectiveness Study of Bone Density Changes in Women Over 40 Following Three Bone Health Plans Containing Variations of the Same Novel Plant Sourced Calcium.  byGilbert R. Kaats, Harry G. Preuss, Harry A. Croft, Samuel C. Keith, Patti L. KeithInt J Med Sci. 2011; 8(3): 180–191. Published online 2011 March 2.  A correction to the original study was published in the Internationa Journal of Medical Science in October of 2013, 

The study that followed 3 groups of post menopausal women over a 3 year period.  At the beginning there were no significant differences between the women in the 3 different groups. Subjects following all three plans had an increase in MAPC: Plan 1=1.30%, Plan 2=2.00%, and Plan 3=4.1%. As you can see, thos following Plan 3 [Plant based calcium as found in AlgaeCal] has the best results.

The study concludes: "This study found that following any of the three Plans was associated with increases in BMD as opposed to merely slowing down the decline in BMD, which had been the general conclusions from a wide range of studies on the efficacy of vitamin D and calcium supplementation.

These increases occurred without adverse side effects. While the study also provides evidence of the benefit of adding the physical activity and health literacy components, the data also support the efficacy of plant-source calcium as a stand-alone product."
