Vitamin "D" can cause a slow human reaction

NEW YORK (Reuters Health) – High doses of vitamin D may help improve memory, but in turn slow down human responses, reveals a new study by scientists at Rutgers University.

The new study involved women aged 50 to 70, divided into three groups. Women in the first group received 600 IU of vitamin D daily for one year.

In the second group, women took 2000 IU of vitamin A per day and the third group, 4000 IU per day.

The researchers found that taking 2,000 IU of vitamin D a day improved the cognitive abilities of study participants by improving memory, concentration, and attention scores.

At the same time, the researchers noted a slow reaction. Women who took 4,000 IU of vitamin A had a slower reaction.
