It turned out that in the elderly it leads to dangerous consequences.
An overabundance of vitamin D can lead to slow reactions and increase the number of accidents among the elderly, according to the Chronicle.info with reference to Znaiu.
To such conclusion scientists from Rutgers University in new Brunswick, once conducted a study of risk factors.
In a randomized controlled study analyzed the effect of vitamin D on three groups of women aged 50-70 years.
Causes of vitamin D deficiency
The first group took the recommended daily dose of 600 IU. The second group took 2000 IU. The third group took 4000 IU.
The results showed improved memory and learning in groups that received a dose exceeding the recommended daily. However, the same group also experienced a slowing of reaction time.
“Slower reaction time can have other negative consequences, such as potential increases the risk of falls and fractures,” explained senior author sue Shapses.
Other researchers also found that consumption of vitamin D is about 2,000 IU per day or more increases the risk of falls, but the cause remained unknown.
The prevalence of vitamin D deficiency and consequences
As suggested by the researchers after conducting this research, the reason for the increased risk of falling may be more delayed reaction time.
According to scientists, the intake of 4000 IU of vitamin D per day is not a problem for young people, but may undermine the ability of older people to walk or keep balance to avoid falling.
More research is needed to determine whether the slower reaction time with an increased risk of falls and injuries.
The next step for further study of this issue could be a study of different doses of supplemental vitamin D in people of different ages and races for a longer period of time.
