Vitamin D levels and cognition in children

We’ve told you about the health benefits of Vitamin D already, but now it seems Vitamin D levels may play a crucial role in the mental health and cognitive function of young individuals, according to a new study, published in Scandinavian Journal of Psychology.

Due to the presence of vitamin D receptors on the brain, researchers believe that vitamin D plays a role in cognitive function, mental health and brain development. Until now, there has not been a lot of research aimed at adolescent and Vitamin D.

When we’re young, our body goes through a lot of changes, some of which are more noticeable than others. Brain development is one of the biggest changes that happen to us, and in many ways these changes are not readily apparent. One of these changes in our cognition is the development of executive functioning. Executive functioning makes up our analytical thoughts (planning and decision making abilities). Development of Executive functioning during the early years is crucial for our later years.

The study evaluated the relationship between vitamin D supplementation and executive functioning among adolescents (ages of 13-14) over the span of 5-6 months. The participants were divided into two groups: a vitamin D group who received 1,520 IU of vitamin D per day and a placebo group. The participants completed two test of executive function before and after the study.

The study found that Vitamin D levels in the experimental group increased. The vitamin D group significantly improved performance results on both of the tests, while the placebo group did not.

Overall, the researchers concluded that those in the vitamin D group experienced improved executive functioning compared to the placebo group. These findings support the theory that vitamin D plays a role in the cognitive function and potentially the development of more intelligent adolescent individuals.

Vitamin D is a fat-soluble vitamin that is essential for maintaining normal calcium metabolism. Vitamin D3  (cholecalciferol) can be synthesized by humans in the skin upon exposure to ultraviolet-B (UVB) radiation from sunlight, or it can be obtained from the diet. This dietary supplement helps promote the body’s absorption of calcium and phosphorous, which are essential for the development and maintenance of healthy teeth and bones.
