It is believed that the elderly, who spend little time in the sun and use sunscreen agents frequently, may be at risk for vitamin D deficiency (which may result in bone disease and fracture), although this has not been proven. To help you get enough vitamin D, it is recommended that you eat food rich in vitamin D, such as fortified milk or fatty fish. Your doctor may also advise you to take vitamin D supplements. Check with your doctor about this.
