Supplements to Prevent Fractures?

Contrary to current opinion, a systematic review of 33 randomized trials in about 50,000 community-living adults over 50 years old found no benefit for supplementation of vitamin D and/or calcium. This study strongly supports the U.S. Preventive Services Taskforce in not recommending calcium or vitamin D supplementation in this population. PositiveTip: Get your vitamin D from…

CVD Risk and Calcium Intake

Inconsistent evidence has suggested there might be an association between calcium supplementation and increased risk for cardiovascular disease. A multi-center, meta-analysis of 4 randomized trials and 27 observational studies has found moderate-quality evidence suggesting that calcium intake (with or without Vitamin D) from food or supplements does not raise the risk of CVD in healthy adults.…

Calcium Underfire

Increased calcium intake from either supplements or dietary sources may not be as effective in supporting bone mineral density (BMD) or reducing fracture risk as once thought.  Researchers found increased calcium intake resulted in only small increases in BMD in 14,000 people over 50, but the changes were so small they would not be clinically significant. Another…

High Calcium Intake May Actually Increase Risk of Hip Fractures

A newly published Swedish study of over 61,000 women who were followed for more than 19 years provides the strongest evidence to date that high calcium intake is not beneficial for preventing bone fractures. The exceptions are women with very low amounts of calcium and vitamin D in their diet. Women in the top 25 percent of…

Millions of women take calcium supplements. The U.S Government recommends 1200 mg intake of calcium per day for men and women over the age of 50.Recent research, just published in the British Medical Journal, show that calcium supplements actually have no beneficial effect on bone density and are actually harmful because they increase the risk of…
