Research Vitamin D
Research Vitamin D - Improving bone density in Osteopenia or Osteoporosis If you search the United States National Institutes of Health (NIH) web site, you will find more than 1300 articles about Vitamin D.
Not all of these concern its role in promoting bone density but a many of them do. Some readers want to read these studies. They want the latest information about Vitamin d research and Osteopenia and Osteoporosis. This page is written for those readers.
NOTE: The web site does offer specific guideline for how much Vitamin D to take but this page if for those who want to check out ABSTRACTSfor themselves.
Now there is no way I can offer links to all 1362 studies - and many of them are concerned with other health issues besides boneloss eg. cancer. But -
Here are summaries of some of these articles:

OBJECTIVE: To examine the relationship between bone mass and serum levels of 25-hydroxyvitamin D and parathyroid hormone in African-American adolescent girls. STUDY DESIGN: A cross-sectional sample at a suburban research center. METHODS: Twenty-one adolescent black girls 12-14 years of age, were studied during winter with biochemical measurements of serum 25-hydroxyvitamin D (25-OHD) and parathyroid hormone (PTH). Bone mass assessment was done with dual energy x-ray absorbsiometry (DXA) and peripheral quantitative computed tomography of the radius (p-QCT). Anthropometric, physical activity and nutritional data were collected.
RESULTS: All participants were vitamin-D deficient (serum 25-OHD level <50 nmol/L), of whom nine (43%) were severely vitamin-D deficient (serum 25-OHD level <20 nmol/L). Mean daily intake of dietary calcium was 540 mg/d and vitamin D was 195 IU/d. There was a positive correlation, although statistically not significant, between serum 25-OHD and various bone mass measurements. Serum PTH was inversely correlated to total body BMD (r = -0.51, p = 0.02) and other bone mineral density at the lumbar spine, total femur and mid-radius.
CONCLUSION: Vitamin-D insufficiency is a widely prevalent problem among adolescent African-American girls. Our data implies that enhancing vitamin-D nutrition resulting in lower serum PTH levels could potentially influence their peak bone mass.
