Our findings revealed a significant difference: baseline FMD was lower in OSA patients compared to the control group. However, after an intravenous injection of vitamin C, the FMD in OSA patients improved dramatically, reaching levels similar to those seen in the healthy controls. Interestingly, vasoreactivity in the control subjects remained unchanged.
These results suggest that oxidative stress might be a key factor contributing to the endothelial dysfunction experienced by individuals with OSA. The positive response to vitamin C opens up exciting possibilities for exploring antioxidant treatments in managing cardiovascular issues related to OSA.
The research specifically focused on the effects of ascorbic acid, or vitamin C, at a concentration of 1.25 g/L added to the drinking water of these rats over 21 days. What we found was quite promising: vitamin C treatment significantly reduced markers of oxidative stress in the plasma and carotid body. This antioxidant appeared to counteract the negative effects typically seen during intermittent hypoxia, including improved ventilatory responses to low oxygen levels and stabilization of heart rate and blood pressure.
Overall, our findings suggest that oxidative stress plays a crucial role in the heightened sensitivity and respiratory changes associated with sleep apnea. By mitigating these oxidative effects through vitamin C, we could potentially improve the quality of life for those affected by this condition.
The results were quite revealing. Participants who consumed higher levels of vitamin C, particularly those in the top intake bracket (around 132.88 to 191.51 mg per day), showed a significant reduction in the risk of developing sleep disorders, including sleep apnea. Specifically, we found that this group had a 25% lower risk of sleep apnea compared to those with lower vitamin C intake.
What's even more encouraging is that this protective effect seemed particularly strong among men and those under 60 years old, suggesting that a sufficient intake of vitamin C could be a worthwhile strategy for preventing sleep apnea. Our findings highlight the importance of diet in managing sleep health and point to vitamin C as a valuable nutrient for those struggling with sleep issues.

Frequently Asked Questions
Sleep apnea is a common and potentially serious sleep disorder characterized by irregular breathing patterns during sleep. Individuals with sleep apnea experience episodes of disrupted or paused breathing, which can occur multiple times throughout the night. These interruptions can last a few seconds to several minutes and often lead to fragmented sleep, which may result in excessive daytime sleepiness, irritability, and difficulty concentrating. The condition can be broadly classified into two main types: obstructive sleep apnea (OSA), caused by a blockage of the upper airway, and central sleep apnea (CSA), which occurs when the brain fails to send the proper signals to the muscles that control breathing.
The diagnosis of sleep apnea typically involves a sleep study, either conducted in a sleep clinic or at home using portable monitoring devices. Treatment options vary depending on the severity of the condition but may include lifestyle changes, the use of continuous positive airway pressure (CPAP) machines, oral appliances, or even surgery in some cases. If left untreated, sleep apnea can lead to various health complications, including cardiovascular issues, metabolic disorders, and impaired cognitive function, making it essential to consult a healthcare professional if you suspect you or someone you know may be affected by this disorder.
Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that plays a critical role in numerous bodily functions. As an essential nutrient, it contributes to the growth and repair of tissues in the body, and it is vital for the production of collagen, an important protein that helps maintain skin, cartilage, tendons, ligaments, and blood vessels. Additionally, Vitamin C acts as a powerful antioxidant, which means it helps combat free radicals—unstable molecules that can cause oxidative stress and contribute to various chronic diseases.
Moreover, Vitamin C enhances iron absorption from plant-based foods, making it a vital component for those following vegetarian or vegan diets. While many people get sufficient Vitamin C from a well-balanced diet that includes fruits and vegetables like oranges, strawberries, kiwi, broccoli, and bell peppers, some individuals might require supplementation. It's generally recommended to stay within the daily intake guidelines, as excessive consumption can lead to gastrointestinal disturbances. Overall, Vitamin C is not just a skincare celebrity—it's a fundamental part of maintaining overall health and well-being.
Based on user reviews, the time it takes to see results when taking a supplement for sleep apnea can vary significantly. Some users report noticing improvements in sleep quality within just a week of taking the supplement, highlighting major gains in both mental and physical strength during that period (Read Review). On the other hand, others have experienced gradual changes over a longer course of nearly two months, with more subtle enhancements in their overall sleep quality and other health aspects (Read Review).
Additionally, one user pointed out that it's still early to draw conclusions about the supplement's effectiveness as they hadn't been taking it long enough to see significant changes, although they did notice feeling more rested upon waking (Read Review). This suggests that individual experiences can vary widely; it may be beneficial to give the supplement a couple of weeks to assess its impact on your sleep apnea symptoms.
Recent research suggests that vitamin C may hold promise for individuals dealing with sleep apnea, particularly through its antioxidant properties. A study involving over 68,000 participants indicated that higher dietary vitamin C intake was associated with a 25% reduced risk of developing sleep disorders, including sleep apnea [1]. Other studies have shown that vitamin C can improve oxidative stress markers and endothelial function in those suffering from obstructive sleep apnea (OSA), highlighting its potential role in managing this condition [7].
However, while these findings are encouraging, it's important to note that much of the research investigates vitamin C as part of combination therapies with other antioxidants, leaving some uncertainty regarding its standalone effectiveness against sleep apnea [2]. Overall, vitamin C appears to be a valuable nutrient that might contribute to improved sleep health, but further controlled studies are warranted to establish clear recommendations regarding its use as a treatment for sleep apnea.
Based on user reviews, many individuals have reported notable improvements in their symptoms after using the supplement. For instance, one user experienced "major improvements in mental and physical strength, as well as sleep quality" within less than a week of taking the product, suggesting a rapid positive response (Read Review). Another user noted significant benefits after nearly two months of use, pointing to a decrease in acne along with enhanced sleep quality, indicating that the formulation may address multiple health aspects (Read Review).
Additionally, some users report subtle, yet encouraging improvements in their waking experience. One user shared that, while still early in their supplementation routine, they found it easier to wake up and felt more rested after sleeping (Read Review). It is essential to remember that individual results can vary, and while some users have experienced significant changes quickly, others may need a bit more time to assess the full effects of the supplement on their symptoms.
Based on user reviews, there is a notable positive sentiment surrounding the combination of this supplement with others, such as MSM and vitamin C. One user highlighted that this combination led to "major improvements in mental and physical strength, as well as sleep quality" in less than a week of use (Read Review). This suggests that users have found synergistic effects from combining these supplements, particularly in enhancing overall well-being and alleviating sleep apnea symptoms.
In addition, another user reported taking the supplement consistently for nearly two months and noticed diminished acne alongside an improvement in sleep quality. This dual benefit further indicates that combining this supplement with others may contribute to multifaceted health improvements, although some users have pointed out the importance of consistency and time in assessing overall effectiveness (Read Review). Overall, while combining supplements may enhance outcomes for managing sleep apnea, individual experiences can vary and depend on dietary habits and overall health.
Research indicates that the optimal dose of Vitamin C for treating sleep apnea lies in the range of approximately 100 to 200 mg per day. A study involving over 68,000 participants found that those consuming between 132.88 to 191.51 mg of Vitamin C daily showed a significant 25% lower risk of developing sleep disorders, including sleep apnea [1]. Additionally, another study highlighted the effectiveness of Vitamin C as part of a combination therapy with antioxidant treatments, suggesting that a dosage around 100 mg twice daily can enhance overall sleep quality [9].
While these findings suggest beneficial effects at these doses, it's important to remember that Vitamin C should ideally be part of a broader treatment strategy for sleep apnea, dealing with oxidative stress and other factors contributing to the condition [2]. Moreover, individual responses to Vitamin C may vary, so consulting with a healthcare provider for personalized guidance and potential adjustments is advisable.

Our findings indicated that endothelial dysfunction is closely linked to increased oxidative stress in OSA patients. When we introduced vitamin C, an antioxidant, we observed improvements in endothelial function. This suggests that oxidative stress plays a significant role in the complications associated with OSA, and that vitamin C may help mitigate some of these effects.
Notably, after six months of continuous positive airway pressure (CPAP) treatment for OSA, we noted further improvements, reinforcing the idea that managing OSA can enhance endothelial health primarily by reducing oxidative stress. However, we acknowledge that while vitamin C showed promise, more controlled studies are needed to fully establish its effects on sleep apnea.
