I found this....
An antiinflammatory effect seems to be the most relevant. There have been few trials designed to judge the effectiveness of melatonin in disease treatment. Most existing data are based on small, incomplete trials. Any positive immunological effect is thought to be the result of melatonin acting on high-affinity receptors (MT1 and MT2) expressed in immunocompetent cells. In preclinical studies, melatonin may enhance cytokine production,[62] and by doing this, counteract acquired immunodeficiences. Some studies also suggest that melatonin might be useful fighting infectious disease[63] including viral, such as HIV, and bacterial infections, and potentially in the treatment of cancer.
Must be. Im not sure why melatonin is apart of thrle protocol

I've always thought it was to help with getting to sleep and staying asleep, our bodies work best while under minimal load
