Vitamin A's impact on OSA
The role of antioxidant vitamins and selenium in patients with obstructive sleep apnea.
Study identifies antioxidant importance
We conducted a case-control study to explore the levels of essential antioxidant nutrients, particularly vitamin A, in patients with obstructive sleep apnea (OSA) who did not have any other health issues. By categorizing our 146 subjects based on their apnea-hypopnea index (AHI) scores, we examined how these nutrient levels compared between those with mild to severe OSA and healthy individuals.

Our findings revealed that patients with OSA showed increased concentrations of vitamin A as part of their antioxidant response. This suggests that vitamin A and selenium may serve as important defenses against the harmful impacts of OSA. The implication of our research highlights that supplementing with antioxidant nutrients could be a beneficial approach to enhance overall health in individuals suffering from sleep apnea.

However, while there is a positive correlation between vitamin A levels and OSA, it is important to note that the isolated effects of vitamin A were not the primary focus of our study. Therefore, more research is needed to fully unravel its specific role in treating or managing sleep apnea.
