Condition
Obstructive Sleep Apnea (OSA)
Obstructive sleep apnea is a sleep disorder in which the airway repeatedly collapses during sleep, causing breathing pauses and drops in oxygen. Vitamin D has drawn the most interest because low levels are common in people with it, though the evidence is limited, and in five melatonin studies insomnia symptoms improved. Evidence for omega-3s, magnesium and N-acetyl cysteine is limited too, and the melatonin findings concern sleeplessness, not breathing pauses.
