Too little vitamin D has been linked to a host of health problems, including obesity, diabetes and high blood pressure, and new research now suggests that a lack of this important nutrient may also contribute to mobility problems in old age. The researchers followed more than 3,000 people between the ages of 70 and 79 for six years, and found that those with the lowest vitamin D levels at the start of the study had nearly a 30 percent increased risk of a mobility limitation at the end of the study and almost twice the risk of a mobility disability as people with the highest levels of vitamin D.
