The role of vitamin D for bone health and fracture prevention

  • Michael F. HolickEmail author
Article

Abstract

Vitamin D inadequacy is pandemic in adults. Vitamin D deficiency causes osteopenia, precipitates and exacerbates osteoporosis, causes the painful bone disease osteomalacia, and increases muscle weakness, which worsens the risk of falls and fractures. Vitamin D deficiency can be prevented by sensible sun exposure and adequate supplementation. Monitoring serum 25-hydroxyvitamin D is the only way to determine vitamin D status. Recent recommendations suggest that in the absence of sun exposure, adults should ingest 1000 IU of vitamin D3 per day. The ideal healthy blood level of 25-hydroxyvitamin D should be 30 to 60 ng/mL. Vitamin D intoxication occurs when 25-hydroxyvitamin D levels are greater than 150 ng/mL. Three recent reports suggesting that vitamin D and calcium supplementation does not decrease the risk of fracture will be put into perspective in light of the vast literature supporting increasing vitamin D and calcium intake as an effective method for decreasing risk of vertebral and nonvertebral fractures.

The authors report on the calcium and vitamin D supplementation arm of the Women’s Health Initiative. Although the authors and the press have concluded that calcium with vitamin D supplementation was of no benefit for decreasing risk of fractures, it should be noted that the patients who took their calcium and vitamin D at least 80% of the time had a 29% reduced risk of hip fracture. Equally important is that most patients were vitamin D-deficient at initiation of the study and those who were vitamin D-deficient at baseline were at higher risk of fracture.PubMedCrossRefGoogle Scholar
