Brief Summary

The role of vitamin D deficiency on increased risk for falls and physical dysfunction is unclear. It is also unclear if taking vitamin D improves physical function and reduces fall risk in older adults. The purpose of this research study is to explore the effects of taking the recommended dose of vitamin D (800 IUs/day) for six months on fall risk and physical functional outcomes in older adults with low vitamin D levels. The investigators hypothesize that the participants will experience fewer falls and function better physically after taking vitamin D for six months.

  • Other significant co-morbid disease (e.g. renal failure on hemodialysis) or severe psychiatric disorder (e.g. bipolar, schizophrenia) that would impair ability to participate in the exercise-based intervention

  • Dietary supplementation with \> 800 IU/day of Vitamin D
  • Hypercalcemia (calcium \> 10.4 mg/dL), hypocalcemia (calcium \< 8.6 mg/dL), or renal insufficiency (estimated glomerular filtration rate (GFR) \< 50 ml/min)
  • Serum aspartate (AST) or alanine transaminase (ATL) \>3 times upper limit normal (UPN)
  • High amounts of physical activity (i.e. running or bicycling) \> 120 min/week
  • Excessive alcohol use ( \>14 drinks per wk )
  • History of drug or alcohol abuse (i.e., more than 5 drinks/day for males or more than 4 drinks/day for females)
  • Planning to leave the area in the next year
