Vitamin D and the impact on bone health of seniors
Senior citizens are prone to having low levels of vitamin D. This is a serious issue that could lead to devastating consequences such as falls, fractures, and osteoporosis.
Vitamin D and falls in older individuals
An analysis of several double-blind randomized clinical trials demonstrated that by supplementing with 700 to 1000 IU vitamin D per day, older people reduce their risk of falling by 20 per cent, whether or not they were also taking calcium supplements. [1]
Vitamin D and fractures in older individuals
Vitamin D in combination with calcium is often used in an attempt to decrease the risk of fractures in bones other than the vertebrae in older individuals [2][3] particularly those in institutional care.[3] An analysis of multiple vitamin D studies determined that a dose of vitamin D 400 IU per day or greater is helpful for individuals aged 65 years or older.[4]
Vitamin D and osteoporosis in older individuals
Osteoporosis consists of a progressive loss of bone mass. Most of our bone mass is built up from the age of 10 to 20 or 30, and after that, we start losing bone mass. [5][6] If too much bone mass is lost as we get older, our bones become fragile and may fracture more easily. Osteoporosis is a devastating and costly disease affecting 10 million Americans; another 34 million have low bone mass, making them more susceptible to osteoporosis.[7] Without intervention, one in two women and one in three men aged 50 and above will experience a fracture due to osteoporosis.[7] The hip, spine, and wrist are the most common sites of fracture, with the hip fracture having the most devastating complications.[8]
Surprisingly, only 20 per cent of people who have suffered a hip or other fracture due to osteoporosis receive treatment. [7]
We are not able to provide you with a recommendation for how much vitamin D one should take on a daily basis. We recommend that you speak with a healthcare professional about your personal situation.
