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.

We aimed to explore the connection between Vitamin D levels and excessive daytime sleepiness in patients diagnosed with obstructive sleep apnea (OSA). In this study, we analyzed serum Vitamin D levels in a group of newly diagnosed OSA patients, dividing them into two categories: those who experienced excessive daytime sleepiness (EDS) and those who did not.
Our findings indicated that patients with EDS had significantly lower levels of Vitamin D compared to their non-somnolent counterparts. The study showed that lower Vitamin D levels correlated with higher apnea-hypopnea indices (AHI) and lower oxyhemoglobin saturation during sleep. This suggests that sleep-related hypoxia may impact Vitamin D status and contribute to sleepiness.
Moreover, our analysis indicated that lower Vitamin D levels were independent predictors of EDS. This further emphasizes the potential role of Vitamin D in managing sleep quality for these patients. In summary, our study highlights an important association between Vitamin D levels and daytime sleepiness in people with sleep apnea, suggesting that improving Vitamin D status could be beneficial for managing EDS in these individuals.

We explored the connection between vitamin D levels and obstructive sleep apnea (OSA) severity in a group of 262 adults who were diagnosed with OSA through polysomnography (a type of sleep study). Our aim was to understand if vitamin D deficiency could influence the severity of sleep apnea symptoms, particularly given the growing evidence linking these two health issues.
In our findings, we observed that 63% of participants had low vitamin D levels, which were associated with increased severity of OSA. The results showed a negative correlation between vitamin D levels and key sleep parameters, meaning that lower vitamin D was linked to worse apnea-hypopnea indices, which measure the frequency of breathing interruptions.
Notably, when we adjusted for various factors like age, sex, and body mass index, our analysis revealed that individuals with higher vitamin D levels had lower chances of experiencing severe OSA. Conversely, those with vitamin D deficiency were nearly three times more likely to have severe symptoms, particularly in individuals over 50 or those categorized as obese.
This study suggests that maintaining adequate vitamin D levels might be important in managing OSA severity. However, it’s essential to note that we did not specifically examine the effects of vitamin D treatment, so more research is needed to determine whether increasing vitamin D can effectively improve sleep apnea outcomes.
Overall, our work highlights the potential role of vitamin D as a modifiable factor in the complex management of obstructive sleep apnea and its symptoms.

We embarked on an intriguing study to see how an eight-week weight loss and lifestyle intervention could influence vitamin D levels in men suffering from obstructive sleep apnea (OSA). Our group of 89 men was split into two; one group received usual care, while the second group engaged in the lifestyle program alongside their standard treatment.
After this intervention, we observed some promising results regarding vitamin D levels. Specifically, the intervention group showed a significant increase in serum 25-hydroxyvitamin D (25(OH)D) levels, with improvements noted at both the end of the 8 weeks and six months later. Indeed, their vitamin D deficiency was potentially resolved.
Moreover, we found that these higher vitamin D levels correlated with better sleep quality, as evidenced by increased sleep efficiency and improvements in several sleep metrics, such as the apnea-hypopnea index (AHI) and oxygen desaturation index. Additionally, body composition measurements, including fat mass, also showed positive changes.
In conclusion, our findings suggest that a coordinated approach combining weight loss and lifestyle changes can be beneficial not just for vitamin D status, but also for overall health aspects related to obstructive sleep apnea.

We embarked on a large-scale study to understand how vitamin D influences obstructive sleep apnea (OSA), especially in those who are obese. Analyzing data from nearly 445,000 participants from the UK Biobank, we focused on individuals who had no previous diagnosis of OSA. The key outcome was the development of new cases of OSA over an average follow-up of 12 years.
What we found was intriguing: higher serum levels of 25-hydroxyvitamin D, the main form of vitamin D in the bloodstream, were associated with a reduced risk of developing new-onset OSA, particularly in participants struggling with obesity. Those with both a body mass index (BMI) of 25 or higher and waist circumference measurements of 90 cm or more showed a significant inverse relationship. This suggests that those with these characteristics might benefit more from maintaining higher vitamin D levels.
The results indicate that while vitamin D supplementation on its own wasn't tested, our findings certainly highlight its potential role in preventing OSA, particularly in at-risk populations. It's a reminder of the importance of monitoring and maintaining adequate vitamin D levels, especially for those dealing with obesity.

Vitamin D linked to sleep apnea severity
We aimed to explore the connection between serum vitamin D levels and the severity of obstructive sleep apnea syndrome (OSAS), particularly in patients also dealing with metabolic syndrome, known as Syndrome Z. Our study involved 270 individuals diagnosed with both conditions. We gathered important data on various aspects, including demographics, sleep patterns, and laboratory results.
From our findings, we observed that a significant number of participants had varying degrees of OSAS severity. Notably, there was a clear trend showing that as the severity of OSAS increased, vitamin D levels decreased. After accounting for various factors, we found a strong association between lower serum 25(OH)D3 levels and greater OSAS severity.
This suggests that monitoring vitamin D levels in patients with the dual challenges of metabolic syndrome and sleep apnea could be vital. While our study highlights an association, we noted it does not directly address the effectiveness of vitamin D3 treatment for improving sleep apnea. Therefore, further research is needed to determine whether boosting vitamin D levels can positively impact sleep apnea symptoms.

We conducted a study aimed at understanding how vitamin D3 might influence obstructive sleep apnea (OSA), particularly in hypertensive, obese patients. The research carefully examined the potential benefits of combining vitamin D3 with a medication called Dapagliflozin, a type of SGLT-2 inhibitor known for its additional cardiovascular advantages.
Over 16 weeks, participants were divided into four groups: those receiving Dapagliflozin, those receiving vitamin D3, those receiving both treatments, and a control group that received no treatment. We looked at a range of health parameters, including weight, blood sugar levels, and quality of life scores, to assess the overall impact of these treatments.
Our findings revealed positive outcomes from using vitamin D3 alongside SGLT-2 inhibitors, suggesting that this combination therapy could help improve cardiac and metabolic health, as well as quality of life in patients struggling with OSA. However, we acknowledged the need for further studies to isolate the specific effects of vitamin D on sleep apnea independently from the benefits provided by the medication.

We aimed to explore the connection between Vitamin D levels and excessive daytime sleepiness in patients diagnosed with obstructive sleep apnea (OSA). In this study, we analyzed serum Vitamin D levels in a group of newly diagnosed OSA patients, dividing them into two categories: those who experienced excessive daytime sleepiness (EDS) and those who did not.
Our findings indicated that patients with EDS had significantly lower levels of Vitamin D compared to their non-somnolent counterparts. The study showed that lower Vitamin D levels correlated with higher apnea-hypopnea indices (AHI) and lower oxyhemoglobin saturation during sleep. This suggests that sleep-related hypoxia may impact Vitamin D status and contribute to sleepiness.
Moreover, our analysis indicated that lower Vitamin D levels were independent predictors of EDS. This further emphasizes the potential role of Vitamin D in managing sleep quality for these patients. In summary, our study highlights an important association between Vitamin D levels and daytime sleepiness in people with sleep apnea, suggesting that improving Vitamin D status could be beneficial for managing EDS in these individuals.

We conducted a pilot study to see how vitamin D3 supplementation impacts individuals with obstructive sleep apnea (OSA). Our double-blind, randomized, placebo-controlled trial involved 19 Caucasian adults with OSA, some of whom were already using continuous positive airways pressure (CPAP) therapy.
Over a 15-week period, participants took either 4,000 IU of vitamin D3 or a placebo. We assessed various outcomes, including drowsiness, quality of life, fatigue levels, and cognitive function. While we observed a significant increase in vitamin D levels among those who received the supplement, we found that it did not improve symptoms related to sleepiness, quality of life, or cognitive performance.
Interestingly, we did notice a decrease in certain metabolic markers, suggesting that vitamin D3 may play a role in improving metabolic health among OSA patients. Overall, while vitamin D3 showed promise in enhancing metabolic parameters, it didn’t seem to alleviate the primary symptoms of OSA. Our findings pave the way for larger studies to further explore these effects.
