A New Supplement Called Calcium-Collagen Chelate May Help Reduce Bone Loss
It’s harder for our bodies to absorb calcium as we age, and menopause leads to an increased risk of osteoporosis in women. A recent study suggests that a combination of collagen and calcium may be better at slowing down bone density loss in post-menopausal women than ordinary calcium and vitamin D.
Participants in the study included 39 post-menopausal women who took either 5 g of calcium-collagen chelate (CC) that included 500 mg of calcium and 200 IU of vitamin D or 500 mg of calcium and 200 IU of vitamin D as a control daily for 12 months.
The researchers assessed total body bone mineral density as well as lumbar and hip bone mineral density at the onset of the study, six months into the study, and at the conclusion of the study by using X-ray absorptiometry. They found that the loss of whole body bone mineral density was much lower in the CC group than in the control group at the end of the study.
The researchers also looked at blood biomarkers of bone turnover at the six month and 12 month points. They found that the CC group had much lower levels of sclerostin and tartrate-resistant acid phosphatase as well as higher bone-specific alkaline phosphatase when compared with the control.
Researchers from Florida State University conducted the study. It was published online ahead of print on October 14, 2014, in the Journal of Medicinal Food.
Approximately 25% of bone structure is collagen. It contributes to bone strength by lending a certain amount of flexibility to the rigid structure, allowing bone to "give" a little under pressure. In preliminary clinical studies, calcium-collagen chelate has been shown to promote both bone strength and bone density.
