Vitamin D is an essential vitamin that is necessary for maintaining healthy bones and teeth, as it helps to absorb calcium into our bodies.
If you aren’t getting enough vitamin D, you can start to have a myriad of problems, such as a lack of energy and the possibility of lowered bone density.
Pros and Cons of Vitamin D
Your body can acquire vitamin D in many ways, including eating plenty of certain types of fish, along with egg yolks, soy milk, egg yolks and oatmeal. Simply standing in the sun helps your body synthesize vitamin D.
Needless to say, having plenty of vitamin D is a good thing – but having too much can pose serious risks. It was found that overweight women in particular, who took three times the recommended daily dose, were more prone to falling thanks to a slower reaction time.
Age also seemed to play a role, as younger people who take 4000 IU of vitamin D per day were found to be less likely to suffer from the same issues.
Increased Risk of Falls
In a recent study by scientists at the Rutgers University in New Brunswick, NJ, they looked into the risk factors for falls in women aged 50-70 in a randomized controlled trial. They were split up into three groups, who took the following amount of vitamin D:
- one group took 4000 IU.
- another group took 2000 IU.
- the last group took 600 IU.
Although all three of the groups showed a remarkable improvement in terms of learning and memory, they also had a slower reaction time – especially those who took the higher dosages.
“The slower reaction time may have other negative outcomes such as potentially increasing the risk of falling and fractures”, said the senior study author, Sue Shapses. “This is possible since other researchers have found that vitamin D supplementation at about 2000 IU daily or more increased risk of falls, but they did not understand the cause.”
It is estimated by the Centers for Disease Control and Prevention that 1 in 4 adults aged 65 and older will suffer from a fall each year.
