Healthy postmenopausal women should not take daily low-dose vitamin D and calcium supplements to prevent fracture (grade D recommendation), the U.S. Preventive Services Task Force said on Tuesday in a draft recommendation statement.
The group says that 400 IU of vitamin D3 and 1000 mg of calcium carbonate taken daily don't reduce osteoporotic fractures and slightly increase the risk for kidney stones.
In addition, the USPSTF determined there was not enough evidence to make recommendations for or against the following:
Vitamin D and calcium supplementation to prevent fractures in men or premenopausal women
Higher doses of vitamin D for fracture prevention in healthy postmenopausal women
Vitamin D â€” with calcium or alone â€” for cancer prevention in adults
