Take Vitamin D to Sleep Better

Updated: Jul 29, 2020

The level of vitamin D in your blood needs to be between 60 and 80 ng/ml for you to get the best sleep. The mechanism by which vitamin D influences our ability to sleep has to do with vitamin D receptors located throughout the brain. A large concentration of these receptors are in the cells of the brainstem, which allows us to sleep. If vitamin D is deficient in the blood, the sleep/wake cycle is disrupted. In addition, vitamin D influences many other hormonal processes in the body, including reproduction, metabolism, digestion, cardiovascular health, all of which influence fatigue and sleep regulation.

Researchers suggest that the increasing rate of sleep disorders over the last 40 years is due in part to widespread vitamin D deficiency since we are spending the majority of our lives indoors or wearing sunscreen outside.
