                                According to the Sleep Foundation, deficiencies in vitamins A, C, D, E, K, and magnesium can negatively affect sleep duration and quality. While no single vitamin is a magic bullet for sleep troubles, ensuring you have sufficient levels of key nutrients can significantly support the biological processes that promote restful sleep.
