We set out to evaluate what effect vitamin D3 supplementation might have on patients suffering from mild obstructive sleep apnea syndrome (OSAS). In this study, 19 adult men who were diagnosed with mild OSAS and had low vitamin D levels participated over an 8-week period. Each week, they took a sizable dose of 50,000 IU of vitamin D3 while undergoing various health assessments. We measured important factors like blood glucose, lipid profiles, and inflammation markers, along with repeated sleep monitoring through polysomnography.
By the end of the study, we observed a significant increase in participants' vitamin D levels, which jumped from an average of 19.5 to 41.8 ng/mL—an indication that the supplementation was effective. Along with this rise in vitamin D, we also noted improvements in fasting blood glucose and total cholesterol levels, as well as a decrease in key inflammation markers. Most encouragingly, the frequency of obstructive apneas and other related sleep disturbances significantly decreased.
Based on these findings, it seems that vitamin D supplementation can play a beneficial role in improving the prognosis for those with mild OSAS. It's exciting to consider how something as simple as a vitamin could lead to better sleep health for individuals struggling with sleep apnea.
