Supplements for Teeth grinding / bruxism.
When teeth grinding / bruxism is the complaint, these are the supplements most often associated with it in the NutriStack library, ranked by how directly each one targets it and by the strength of the evidence.
Ranked by relevance, top first.
Relevance reflects how directly each supplement targets this symptom in the NutriStack map. Evidence is the supplement’s own rating. Open any name for the full profile.
- 01Magnesium GlycinateLimited82% match
Magnesium supports neuromuscular relaxation and modulates NMDA-receptor excitation, which may help reduce jaw muscle hyperactivity, though bruxism-specific evidence is limited.
SuggestedMagnesium glycinate - 02L-TheanineLimited74% match
L-theanine promotes alpha-wave activity and may raise GABA tone, which could lower the nighttime arousal and stress that often drive sleep bruxism.
SuggestedL-theanine (Suntheanine) - 03TaurineLimited64% match
Taurine is an inhibitory neuromodulator that may dampen central excitability, with plausible but unproven relevance to masticatory muscle overactivity.
SuggestedTaurine capsules - 04Vitamin B6Limited60% match
Vitamin B6 is a cofactor for GABA and dopamine synthesis, pathways involved in motor control and stress regulation, but a direct link to grinding is theoretical.
SuggestedPyridoxal-5-phosphate (P5P) - 05Vitamin B5Limited56% match
Vitamin B5 (pantothenic acid) supports acetylcholine synthesis and adrenal steroidogenesis, an indirect and speculative link to stress-related muscle tension.
SuggestedPantothenic acid (calcium pantothenate) - 06CalciumLimited54% match
Calcium is essential for normal muscle contraction and relaxation cycles, so adequacy supports baseline neuromuscular function rather than directly treating grinding.
SuggestedCalcium citrate
