Elderly women should take more vitamin D supplementation during the wintertime, suggests researchers

Osteoporosis is one of the chief reasons why the elderly often suffer broken bones from relatively minor injuries. Postmenopausal women in particular experience a relatively rapid loss in bone mass due to a reduced concentration of oestrogen, which is responsible for strong bone growth during youth. Maintaining bone mass requires physical exercise and vitamin D, which is mainly produced in the skin with the help of UVB radiation. This is why, especially in the wintertime, many elderly women are prescribed a vitamin D supplement by their doctor to maintain bone mass.
