Algae-Derived Calcium May Improve Bone Health in Mature Women
After midlife, it’s normal for people to experience an average bone loss of around 1% per year. A recent study suggests that taking a daily supplement of algae-derived calcium may increase bone mineral density in healthy women with age-related bone loss.
Participants in the study included 172 healthy women who were registered consumers of an algae-derived calcium product called AlgaeCal for one to seven years, had at least one dual-energy x-ray absoptiometry bone mineral density and/or blood chemistry test, and had not taken bisphosphonates or other anti-resporptive or bone anabolic medications. All of the participants also took a strontium citrate supplement along with the AlgaeCal and they volunteered to complete complimentary bone mineral density tests.
The researchers found that the algae-derived calcium was associated with a significant increase of bone mineral density of 1.04% per year and 7.3% over the seven-year study period. No adverse effects or safety concerns were found.
Researchers from Integrative Health Technologies, Georgetown University Medical Center, Creighton University, and Transdermal Biotechnology, Inc., conducted the study. It was published online ahead of print on February 17, 2016, in the Journal of the American College of Nutrition.
Calcium is best known for its effect on bone health, but previous studies suggest it can also help with weight loss, skin health, and reducing the risk of stroke. Some studies have even suggested that calcium intake is associated with increased longevity.
Calcium absorption decreases as we age, so it is especially important to make sure you are getting enough. While the more common types of calcium come from dairy products, previous studies suggest that algae-derived calcium may in fact be more effective than more common types of calcium.
