Calcium Compound May Enhance Bone Health in Elderly

PHOENIX--At a meeting of the American Society for Bone and Mineral Research (ASBMR), researchers announced that active absorbable algal calcium (AAA Ca), a calcium compound, may be able to prevent fractures in postmenopausal women. The double blind, placebo-controlled prospective study ( involved 80 elderly men and osteoporotic women who were divided into three groups: 900 mg/d AAA Ca, 900 mg/d calcium carbonate (CaCO3) and placebo. All groups were given an additional 600 mg/d calcium from food sources.

After 27 months, the AAA Ca group reported no fractures, while the CaCO3 group reported 357 fractures and the placebo group reported 500 fractures. By measuring patients' lumbar vertebral body throughout the study period, Takuo Fujita, M.D., director of the Osteoporosis Foundation in Japan, found that only 22.2 percent of AAA Ca users lost more than 20 percent of this measurement, as opposed to 36.4 percent among CaCO3 group and 50 percent in the placebo group.

The AAA Ca used in this study is marketed as AdvaCAL by LaneLabs-USA Inc. (
