Myofascial pain syndrome
Supplements studied for myofascial pain syndrome.
Overview
SupplementDEX lists only L-Tryptophan for myofascial pain syndrome, rated low across effect size, evidence, and trust from two studies. One trial found 3 grams daily with diet changes did not reduce chronic jaw pain versus no treatment; other research on facial pain has been inconsistent and does not clearly support a benefit.
With a single supplement and mixed findings, the evidence base is too thin to draw reliable conclusions. L-Tryptophan's low weighted average and ratings reflect this uncertainty.
