A recent study suggests a correlation between vitamin D deficiency and impaired cognitive function, also known as brain fog.
Brain fog is a general term used to describe feelings of mental haziness, confusion, and lack of focus. It can be caused by many factors, including stress, anxiety, depression, and poor nutrition.
The study examined the cognitive function of 3200 participants aged 18-30. They found that those who had low levels of vitamin D were more likely to experience brain fog than those with normal levels.
While the study does not prove that vitamin D deficiency causes brain fog, it provides evidence of a potential link. If you are experiencing symptoms of brain fog, ask your doctor to test your vitamin D levels and see if supplementation is necessary.
