Supplementing with 5-HTP or consuming tryptophan-rich foods may enhance serotonin availability for improved sleep.

“There is starting to be some data, and I emphasize starting because it's not a very robust literature yet, looking at whether or not supplementing precursors to serotonin like 5-HTP, which can be taken in a supplement form or consuming foods that increase serotonin naturally. So these would be any foods that contain high levels of tryptophan. You can look up what those are. So, white meat turkey, for instance, certain complex carbohydrates can often be rich with tryptophan. That consuming those foods can enhance the amount of serotonin that's available in the brain and blood and thereby lead to the particular quality of sleep that allows for more deep healing or for when I say deep healing, I mean for a more robust immune response.”
