High dose vitamin D and sleep effects
A recent study has shown that taking high doses of vitamin D, at a rate of 5,000 international units or more daily, is associated with improved results on cognitive tests in people suffering from sleep disorders and mild cognitive impairment. These individuals scored approximately 3.8 points higher on the MoCA test compared to those who do not take it daily. However, the study cautioned against interpreting these results as evidence of the efficacy of high doses, as it did not establish that vitamin D causes improvements in cognitive abilities. The study was an exploratory small-scale investigation, and the dosage exceeded the recommended safety limit of 4,000 international units for adults. The findings highlight the need for further research to precisely determine the relationship.
