How does Vitamin B6 affect Our Sleep?

What is Vitamin B6?

Vitamin B6, also known as pyridoxine, is one of the B vitamins essential for human health.

Dream Recall: Some studies suggest that Vitamin B6 may enhance dream vividness or recall, which is an indicator of healthy, rapid eye movement (REM) sleep.
