This Thursday after digging into your delicious Thanksgiving meal, you might find yourself slouching on your sofa, pants feeling a little snug, and you might find yourself feeling a dozy. Your first inclination will likely be to blame that delectable turkey and all of that tryptophan. Because turkey has tryptophan, and tryptophan makes us sleepy, right?
Well… This may likely be a myth that we have all been telling ourselves. The science behind tryptophan is pretty clear: tryptophan is an essential amino acid that our bodies need to help make niacin and serotonin. Our bodies do not produce tryptophan, so we must get it from our diet. Serotonin is believed to help us sleep better and stabilize our moods. It would appear, then, if tryptophan helps us make serotonin, and serotonin helps us sleep, that consuming tryptophan would make us sleepy, right?
