Can’t sleep? Eat peanuts. Peanuts are full of niacin and tryptophan. Niacin and tryptophan are two sleep inducing powerhouses.
Niacin is also known as vitamin B3. Niacin is an essential B vitamin found in foods. The body converts niacin to niacinamide. Once ingested, some of the niacinamide is converted to nicotinamide. The form of niacin found is supplements might be niacin or nicotinamide.
Nicotinamide has some ability to help induce sleep. It is possible that when the level of niacin is adequate the pathway your body uses to make niacin is inactivated. Because the pathway uses tryptophan, it is postulated inactivation of the pathway to make niacin makes more tryptophan available for making melatonin. Tryptophan is a precursor to melatonin. Melatonin is a hormone that helps usher in sleep.
When you eat peanuts, you provide your body with a direct source of tryptophan. Peanuts are digested and turned into tryptophan which is used to make melatonin.
Have a little peanut butter on an apple slice and head for bed.
