Primary Outcome Measures:
  • Changes in Bone Mineral Density (BMD) [ Time Frame: baseline and 6 months ]
    Measurements of bone mineral density were conducted at baseline and 6 months from baseline in two different study groups following the same bone-health behavior modification plan, but with different versions of a bone-health calcium supplement.

Secondary Outcome Measures:
  • A comparison of changes from baseline in 43-blood chemistry panel and a self-reported quality of life inventory in both study groups [ Time Frame: six months ]
    Study subjects in both arms of the study completed a fasting 43-blood chemistry panel and an 84-item self-reported quality of life inventory at baseline and again after participating in the study for six months. No significant differences were found in the within-group changes from baseline or between the groups on both sets of measures.

Enrollment: 354
Study Start Date: June 2006
Study Completion Date: March 2010
Primary Completion Date: July 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Effects of taking AlgaeCal-1
Following a bone health plan with Algae-cal-1 supplement
Dietary Supplement: AlgaeCal-1
Daily consumption of 7 capsules containing bone health ingredients
Active Comparator: Effects of taking AlgaeCal-2
Following a bone-health plan while consuming AlgaeCal 2
Dietary Supplement: AlgaeCal-2
Taking 7 capsules a day for six months

Detailed Description:

The US Surgeon General's Report on Bone Health suggests America's bone-health is in jeopardy and issued a "call to action" to develop bone-health plans that:

  1. improve nutrition,
  2. increase health literacy and,
  3. increase physical activity.

The purpose of this study was to use a comparative effective research model to compare 6-month changes in bone mineral density (BMD)in two study groups. Both followed the same bone health plan that contained the three components listed above with the same plant-source calcium supplement, but enhanced with different levels of calcium, vitamin D3, vitamin K and magnesium.
