New evidence
The only randomized trial on vitamin D for jaw pain found it worked no better than diclofenac — but that's based on a single study.
This is the first systematic review to look at diet and temporomandibular disorder, but with just one small trial on vitamin D, the evidence is too thin to draw any conclusion — treat this as an early signal, not a settled answer.
A systematic review of nutrition and temporomandibular disorder (TMD) found that the only randomized trial comparing vitamin D to the anti-inflammatory drug diclofenac showed no significant difference in pain relief. The overall evidence linking any dietary component to TMD symptoms was limited, inconsistent, and insufficient to prove cause and effect.
Where this fits in the evidence
This is among the first studies we've indexed on Vitamin D for Reduced Pain Intensity — treat it as an early signal until more research accumulates.
