How do I choose safe adjunctive supplements for sleep apnea?
Shelf order follows safety-and-fit for nightly use rather than trial size alone: magnesium glycinate leads as the best-tolerated non-sedating adjunct, omega-3 carries the strongest supplement trial evidence (cardiovascular protection in CPAP-treated patients), and vitamin D3 closes for deficiency correction. The one absolute rule: nothing on this shelf treats the apnea, and nothing sedating belongs on it. The products below are educational examples — not medical recommendations.
Magnesium Bisglycinate
by Thorne · Airway Muscle Relaxation
Score
Highly bioavailable magnesium bound to glycine. Does not act as a CNS depressant — the critical safety property in OSA, where sedating supplements worsen airway collapse. High doses can cause diarrhea. Consult a doctor if on blood pressure medications. Not a treatment for sleep apnea.
