We conducted a study to see if high-dose vitamin D3 could improve vascular health and reduce fatigue in individuals suffering from chronic fatigue syndrome (CFS). This was a well-structured trial involving 50 participants, all of whom met specific diagnostic criteria for CFS. Participants were divided into two groups: one received 100,000 units of vitamin D3 every two months, while the other received a placebo over a period of six months.
Despite a noticeable increase of 22 nmol/L in vitamin D levels for those who received the treatment compared to the placebo group, we found no significant benefits. There was no change in arterial stiffness, a key vascular health indicator, nor improvements in overall fatigue as measured by the Piper Fatigue scale.
In essence, our findings indicate that high-dose oral vitamin D3 does not offer the hoped-for relief in vascular function or fatigue for patients with chronic fatigue syndrome. This suggests that other therapeutic options may need to be explored for individuals suffering from this condition.

Vitamin D treatment enhances alertness
Resolution of hypersomnia following identification and treatment of vitamin d deficiency.
We explored the impact of vitamin D treatment on a case of excessive daytime sleepiness (EDS), specifically in the context of chronic fatigue syndrome. A 28-year-old woman was found to have low levels of vitamin D after experiencing four months of overwhelming fatigue and sleepiness, despite being tested for sleep disorders.
After starting vitamin D supplementation, her condition improved remarkably within just two weeks. Along with a boost in alertness, her associated symptoms like muscle pain and headaches began to fade. By the end of the treatment, her score on the Epworth Sleepiness Scale, which measures daytime sleepiness, dropped significantly, indicating much better daytime function.
This case suggests that vitamin D may play a role in improving symptoms commonly linked to chronic fatigue syndrome. While more research is needed to fully understand the mechanisms behind this improvement, our findings open the door to potentially screening patients with chronic fatigue for vitamin D deficiency to expedite treatment.

Oral supplement aids long COVID symptoms
Potential Anti-Inflammatory and Anti-Fatigue Effects of an Oral Food Supplement in Long COVID Patients.
We conducted a double-blind, placebo-controlled trial to evaluate the effects of an oral food supplement (OFS) on long COVID patients, particularly focusing on chronic inflammation and fatigue. The supplement included components like rosehip, propolis, royal jelly, and zinc, with vitamin C being a key ingredient.
Through our two-month study, which involved giving participants either the OFS or a placebo, we made some interesting observations. Notably, patients who took the OFS experienced a significant reduction in inflammatory markers, which are often linked to chronic fatigue syndrome. This included improvements in the neutrophil-to-lymphocyte and monocyte-to-lymphocyte ratios.
We also noted a substantial increase in vitamin D levels among those taking the supplement, which correlated with enhanced quality of life and decreased fatigue as measured by the fatigue severity scale. Our findings suggest that the combination of ingredients in the OFS, particularly its vitamin D content, can help alleviate some symptoms associated with long COVID, especially chronic fatigue.
However, since the supplement included multiple active ingredients, isolating the specific impact of vitamin D on chronic fatigue syndrome is challenging. Still, the overall results indicate positive changes for patients dealing with the lingering effects of COVID.

Beta-glucan shows cognitive improvements
Yeast Beta-Glucan Supplementation with Multivitamins Attenuates Cognitive Impairments in Individuals with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome: A Randomized, Double-Blind, Placebo-Controlled Trial.
We conducted a randomized, double-blind, placebo-controlled trial to explore how yeast beta-glucan, along with multivitamins, affects individuals suffering from Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). In our study, 65 participants received either beta-glucan combined with vitamins and zinc or a placebo for 36 weeks.
Interestingly, while our primary focus was on beta-glucan, which was shown to significantly improve cognitive fatigue, the role of vitamin D3 within this combination was not clearly established. This makes it challenging to directly assess the impact of vitamin D3 alone on chronic fatigue syndrome outcomes.
Overall, we discovered that beta-glucan supplementation could positively influence cognitive fatigue, offering promise for future research on nutritional support in ME/CFS patients. However, definitive conclusions about vitamin D3's effectiveness remain inconclusive due to the combined nature of the treatment.

Frequently Asked Questions
Chronic Fatigue Syndrome (CFS), also known as Myalgic Encephalomyelitis (ME), is a complex and debilitating condition characterized by profound fatigue that doesn’t improve with rest and worsens with physical or mental activity. This crippling fatigue is often accompanied by a variety of symptoms, including sleep disturbances, cognitive difficulties, muscle pain, and joint pain. Unlike typical tiredness, the fatigue experienced in CFS is long-lasting, and it can significantly hinder everyday activities and overall quality of life.
The precise cause of CFS remains unknown, but it is believed to be influenced by a combination of genetic, environmental, immunological, and psychological factors. Diagnosis primarily relies on a careful assessment of symptoms, as there are no definitive laboratory tests available. Treatment options focus on symptom management and may include lifestyle changes, physical therapy, medication for pain management, and cognitive behavioral therapy. Given the complexity and variability of the condition, individuals with CFS should consult healthcare professionals who specialize in this area to develop personalized management strategies.
Vitamin D is a fat-soluble vitamin that's essential for maintaining healthy bones and teeth, supporting immune system function, and facilitating normal cell growth and development. It plays a crucial role in calcium absorption in the gut, which is vital for bone health. Unlike most vitamins, our bodies can produce Vitamin D when exposed to sunlight, specifically UVB rays, which is why it’s often referred to as the "sunshine vitamin." However, depending on your geographical location, lifestyle, and skin type, getting sufficient Vitamin D from the sun alone can be challenging, particularly during the winter months.
In addition to sunlight, Vitamin D can be obtained from certain foods such as fatty fish (like salmon and mackerel), fish liver oils, and fortified foods like milk and cereals. Some individuals may also consider supplements, especially if they're at risk for deficiency. Insufficient vitamin D levels are linked to various health issues, including rickets in children, osteomalacia in adults, and even an increased risk of chronic diseases. Regularly checking your vitamin D levels and consulting with a healthcare professional can help ensure you're meeting your needs for optimal health.
Chronic Fatigue Syndrome (CFS) is a complex disorder characterized by extreme fatigue that doesn't improve with rest and may be exacerbated by physical or mental activity. While the causes of CFS remain unclear, there is ongoing research into various interventions that may alleviate its symptoms, including vitamin D supplementation. Some studies suggest that low levels of vitamin D could be linked to fatigue and may play a role in immune function, potentially impacting CFS. However, definitive clinical evidence confirming that vitamin D can help specifically with CFS is still lacking.
If you suspect that low vitamin D levels could be contributing to your fatigue, it might be worthwhile to discuss this with your healthcare provider. They can recommend blood tests to assess your vitamin D status and evaluate the potential benefits of supplementation if necessary. It's important to approach any treatment plan for Chronic Fatigue Syndrome comprehensively, as this multifaceted condition often requires a combination of therapies tailored to individual needs.
Based on user reviews, most individuals taking Vitamin D for Chronic Fatigue Syndrome report noticeable improvements within a month. For example, one user highlighted that after a month of supplementation, both they and their husband experienced significant health improvements, with their vitamin levels nearing normal (Read Review). Another review confirmed instant effects, with symptoms of drowsiness and fatigue disappearing shortly after starting the supplement (Read Review).
Users have also emphasized the importance of maintaining an adequate dosage. One reviewer noted that increasing their dosage led to a marked improvement in energy levels within the same timeframe (Read Review). Overall, if you're considering Vitamin D supplements for Chronic Fatigue Syndrome, it appears that a month is a common period to start seeing positive results.
The scientific support for specific supplements targeting Chronic Fatigue Syndrome (CFS) varies, with results indicating mixed outcomes. Notably, high-dose vitamin D3, despite its preliminary popularity, has been evaluated in multiple studies without showing significant benefits. One controlled trial found that administering 100,000 units of vitamin D3 every two months resulted in no improvements in fatigue or vascular health among CFS patients [2]. This aligns with other investigations that concluded similar findings about vitamin D3's efficacy in reducing CFS symptoms [2].
On a different note, a recent study focused on an oral food supplement (OFS) underlined potential advantages for those experiencing chronic fatigue linked to long COVID, showing reductions in inflammatory markers and improvements in fatigue levels [1]. However, due to the multi-ingredient nature of the OFS, accurately attributing specific effects to vitamin D alone remains challenging. Additionally, some case reports suggest vitamin D supplementation may improve symptoms for individuals already deficient, but definitive large-scale conclusions for CFS are yet to be established [3]. Overall, while specific supplements like vitamin D3 may not deliver the anticipated relief for CFS, alternative options may still benefit patients depending on their individual needs.
Based on user reviews, individuals taking Vitamin D for chronic fatigue have reported a range of improvements in their symptoms. Many users note a significant reduction in feelings of drowsiness and chronic fatigue after beginning supplementation. For instance, one user found that not only did their own symptoms improve, but their husband's chronic fatigue and apathy also lessened after a month of taking vitamin D (Read Review). Another reviewer reported an almost immediate effect, with symptoms disappearing shortly after starting the supplement (Read Review).
Dosage adjustments appear to play an essential role in effectiveness, as one user experienced substantial improvements in mood and energy levels after increasing their intake from 10,000 IU to 5,000 IU, as recommended by their doctor (Read Review). In addition, multiple users, including a family member noted for their chronic fatigue, experienced significant health benefits after a month of consistent vitamin D intake, suggesting a potential positive correlation between long-term use and symptom alleviation (Read Review). However, it's important to remember that individual results can vary, and not every user may experience the same level of improvement.
In user reviews, there is a consensus that combining Vitamin D with other supplements can enhance its effectiveness in combating Chronic Fatigue Syndrome. One user noted that after following a doctor's recommendation and adjusting their dosage from 10,000 IU to 5,000 IU, they experienced improved energy levels and mood, indicating that mindful supplement management plays a critical role in outcomes (Read Review). Similarly, another reviewer observed significant health benefits after their brother began taking Vitamin D, which suggests that when used alongside other treatments, it can lead to notable improvements in fatigue-related symptoms (Read Review).
Additionally, users have reported that taking Vitamin D during the first half of the day optimizes its invigorating effects, hinting at the potential for combining timing with other supplements to achieve better results. One user specifically mentioned that it alleviated their chronic fatigue and drowsiness quickly, demonstrating the synergistic benefits of such combinations (Read Review). However, specific details on which other supplements were commonly paired with Vitamin D were not highlighted in the reviews, suggesting further exploration by users may be beneficial.
Based on user reviews, many individuals report that Vitamin D can significantly alleviate symptoms associated with Chronic Fatigue Syndrome when taken in appropriate doses. One user noted that after taking 10,000 IU for a month, they transitioned to a 5,000 IU daily dosage as advised by their doctor, resulting in improved mood and energy levels (Read Review). Another review highlighted the importance of Vitamin D, particularly in colder climates, emphasizing that it had effectively eliminated drowsiness and chronic fatigue after adjusting their levels to what they deemed adequate (Read Review).
Moreover, users commonly reported that Vitamin D3 offered quick relief for symptoms of fatigue, with some suggesting that morning intake may enhance its energizing effects (Read Review). Consistent dosing seems to be key, as one reviewer mentioned the positive outcome after a month of supplementation, eventually leading to sustained energy and reduced tiredness (Read Review). Overall, user experiences suggest that while individual needs may vary, a dose of around 5,000 IU, potentially starting higher, is often reported to bring significant benefits.
