Supplements for fall prevention are usually targeted at managing conditions that increase the risk for fracture or other acute conditions during a fall. For example, vitamin D and calcium have been studied for preventing fall-related injuries, as these nutrients help to stave off osteoporosis.[1] However, some evidence suggests that high-dose vitamin D may actually be associated with an increased risk of falls when compared to lower doses, although it’s not clear why that would be the case.[2][3].
