It cannot be stated that getting more vitamin D will actually lead to stronger muscles and preserve physical function. This is due to the fact that our if we get enough sunlight our bodies make vitamin D naturally. It can be concluded that participants with better physical function had higher vitamin D simply because they were outside more often. As Houston points out: “Current dietary recommendations are based primarily on vitamin D’s effects on bone health. It is possible that higher amounts of vitamin D are needed for the preservation of muscle strength and physical function as well as other health conditions. However, clinical trials are needed to definitively determine whether increasing 25-hydroxyvitamin D concentrations through diet or supplements has an effect on these non-traditional outcomes.”
