Excessive consumption of vitamin D negatively affects its benefits

Although vitamin D has many health benefits, patients should take the right dose, according to a recent medical study.

Older women, obese and taking more than three times the recommended daily dose of vitamins, have shown improvements in memory and learning, but their reactions have also been slow.

The researchers hypothesized that the slower reaction time could increase the risk of falls in the elderly. Researchers at the New York University School of Medicine used a computer to evaluate the effect of vitamin D on cognitive function. They evaluated three groups of women aged 50 to 70 in a randomized trial.

One group took the recommended daily dose of 600 IU, which corresponds to 15 micrograms of vitamin D per day for one year, another group of 200 IU per day and the third of 4000 IU. Women advise their lifestyle and have been encouraged to lose weight.

The researchers found an improvement in memory and learning ability in the group taking 2,000 IU vitamin D per day, but not in the highest dose group, while the study found showed that women's reaction time was slower than that of women who received high doses. Vitamin, which can have other negative consequences such as the possibility of an increased risk of falls and fractures.

The study notes that cognitive impairment and dementia are major public health problems, particularly with age. Evidence suggests that vitamin D plays a role in the normal functioning of the central nervous system.
