vitamin A
When coupled with Vitamin E helps tell our bodies when it’s time to sleep or stay awake, and once we do fall asleep they help create and store up gobs of energy.
Plays an essential role in setting our circadian rhythm and allowing good sleep.
When blue light from sunshine enters our eyes, vitamin A translates it into a signal that tells our brain it is daytime. When this signal slows, our brain knows that it is nighttime. This means that vitamin A plays an essential role in helping us fall asleep on time, get high quality sleep, sleep long enough, wake up feeling rested, and staying alert and energetic throughout the day.
Without vitamin A, our brains cannot know when it is daytime and cannot set our circadian rhythm. If this system fails, we are less likely to feel alert in the daytime, less likely to feel relaxed in the night time, and less likely to get adequate, regular, restful sleep.
