Vitamins B2, B6, B 12, folic acid and nicotinic acid are all considered to be closely related to sleep. Vitamin B2 has the functions of maintaining the health of nervous system and eliminating irritability, and can improve the sleep status of people who have difficulty sleeping and often wake up in the middle of the night. Vitamin B6 can help to produce serotonin. Together with vitamin B2 and B 12, it converts tryptophan into nicotinic acid.

If the human body lacks nicotinic acid, it will often be anxious and irritable, and then it will not sleep well. Nicotinic acid is commonly used in medicine to improve insomnia caused by depression. Foods rich in B vitamins include whole wheat products, meat and eggs. ?
