Augmenting the serotonin system through tryptophan or 5-HTP supplementation is being investigated for its potential to increase glymphatic circulation, leading to faster recovery and potentially boosting immune system activity.

“And I am aware of some studies that are ongoing now where augmenting the serotonin system through either supplementation of tryptophan or 5-HTP or even serotonin itself, these are laboratory studies, is being looked at for its capacity to increase the amount of circulation in the glymphatic system. And the idea is that it might, and I want to underscore might, potentially lead to more rapid recovery from injury and illness and potentially ramp up, if you will, the activity of the immune system.”
