Vitamin D3 improves mild sleep apnea
The effects of vitamin D supplemantation on prognosis in patients with mild obstructive sleep apnea syndrome.
Focus on vitamin D3 impact
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.

Vitamin D3 enhances metabolic health
Vitamin D Improves Selected Metabolic Parameters but Not Neuropsychological or Quality of Life Indices in OSA: A Pilot Study.
Directly related to vitamin D3
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.

Vitamin D linked to sleep apnea severity
The Association of Serum 25(OH) Vitamin D Level with Severity of Obstructive Sleep Apnea Syndrome in Patients with Syndrome Z (the Interaction of Obstructive Sleep Apnea with Metabolic Syndrome).
Moderate association, no treatment effect
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.

Improved sleep quality
It effectively addressed my husband's nocturia and my own sleep issues. Previously, I would wake at least twice nightly, feeling exhausted. After taking this vitamin D supplement daily, I noticed immediate improvements in my sleep quality, allowing me to rest through the night. It's considerably cheaper than other products I tried, and I’m grateful for NOW Foods and iHerb.

Stronger bones
Wonderful! Vitamin D3 is vital for calcium and phosphorus absorption, which is crucial for bone strength, especially at my age. I take it daily after breakfast as a preventive measure. Since raising my vitamin level to 49ng/ml, I have experienced increased energy and better sleep. The capsules are small and easy to take, and I trust this manufacturer completely. Recommend to all!

Improved energy
I have been taking this vitamin for years, primarily in autumn and spring. I've adjusted my dose from 5000 to 2000 IU since my levels are now normal. I feel more energetic and rarely struggle with daytime sleepiness, which has drastically improved my daily life. My family takes it as well.
