We explored the effectiveness of high-dose vitamin B12 injections on chronic fatigue syndrome (CFS) through two case reports that utilized N of 1 trials. This approach allowed us to make tailored treatment decisions based on individual responses to the therapy.
In one case, we found that high-dose vitamin B12 injections did not yield positive results, leaving the patient without significant relief from their symptoms. Conversely, in another case, we observed that nimodipine proved to be a very effective treatment for that patient’s chronic fatigue.
These findings suggest that while vitamin B12 may not be helpful for everyone suffering from CFS, other treatments like nimodipine can be beneficial. Thus, personalized treatment strategies are key in managing this complex and varied condition.

Folinic acid improves CFS symptoms
Clinical activity of folinic acid in patients with chronic fatigue syndrome.
We aimed to explore the effects of folinic acid, also known as leucovorin, on patients suffering from chronic fatigue syndrome (CFS). Our investigation revealed some fascinating findings about this often misunderstood condition, particularly the links to immune response and Epstein-Barr virus (EBV) infection.
In our evaluation of 58 CFS patients, we discovered that nearly all had previously been exposed to EBV, with a striking 72% showing signs of active reactivation. Additionally, an overwhelming 94% were found to have a severe B-cell immunodeficiency, evidenced by a marked reduction in their CD19+IgM+ mature B-lymphocyte population.
What stood out was that after treatment with folinic acid, an impressive 81% of the participants reported experiencing a noticeable improvement in their symptoms. This suggests that folinic acid might play a significant role in the management of CFS, particularly for those struggling with related immune deficiencies and EBV responses.
Our findings bring new insights into CFS, indicating that it may be a condition responding well to folinic acid treatment. This opens up exciting avenues for further research into effective therapies for those affected by this challenging syndrome.

Folate improves fatigue-related disorders
Folate-responsive neurological and mental disorders: report of 16 cases. Neuropsychological correlates of computerized transaxial tomography and radionuclide cisternography in folic acid deficiencies.
We examined two groups of patients who exhibited neurological and psychiatric disorders responsive to folic acid treatment. The first group of seven individuals suffered from an acquired folate deficiency due to either poor absorption of nutrients or an inadequate diet. Their symptoms included significant fatigue, weight loss, and various neurological impairments. The second group, consisting of nine patients, presented idiopathic folate deficiency with chronic fatigue and family histories of restless legs syndrome.
Through neuropsychological testing, we observed abnormal intellectual functioning in all patients, along with issues highlighted on imaging studies like computerized transaxial tomography. Remarkably, after 6 to 12 months of folic acid therapy, a substantial improvement in their cognitive abilities and overall functioning was recorded.
This suggests that addressing folate deficiency might alleviate some aspects of fatigue and cognitive decline commonly associated with chronic fatigue syndrome. Our findings imply that long-term folate supplementation may lead to positive changes in those struggling with fatigue-related conditions, although the label of chronic fatigue syndrome was not explicitly used.

Beta-glucan shows cognitive benefits
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 study exploring the effects of beta-glucan combined with vitamins, including vitamin B6, on individuals with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). This research involved a 36-week trial where 65 participants were split into two groups: one received a daily supplement containing beta-glucan and vitamins, while the other received a placebo.
While the beta-glucan supplementation showed promising results in reducing cognitive fatigue, the specific impact of vitamin B6 on chronic fatigue syndrome was not clearly determined. This is because vitamin B6 was part of a combination treatment, making it difficult to assess its isolated benefits.
Ultimately, we observed that yeast-derived beta-glucan might hold potential in alleviating cognitive challenges associated with ME/CFS, which opens up avenues for further research. However, it’s important to remember that additional studies are needed to fully understand how vitamin B6 and other components contribute to this condition.

Vitamin B12 drops show promise
Open Trial of Vitamin B12 Nasal Drops in Adults With Myalgic Encephalomyelitis/Chronic Fatigue Syndrome: Comparison of Responders and Non-Responders.
We examined the impact of vitamin B12 nasal drops on individuals suffering from myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). Our study involved fifty-one patients, predominantly female, with an average age of 42 and an average illness duration of 16 years.
After three months of treatment, we measured their vitamin B12 serum levels, physical activity, and fatigue and concentration levels. Interestingly, we found that the participants who responded positively to the treatment experienced significant improvements in their vitamin B12 levels, daily step count, and overall physical activity. Moreover, those who reported a positive response noted a decrease in fatigue levels.
On the flip side, those categorized as non-responders had only a modest increase in vitamin B12 levels, with no notable improvement in other measures. Overall, our findings suggest that nasal drops could serve as a viable alternative to vitamin B12 injections, especially since around two-thirds of participants reported feeling better after treatment. This pilot study opens up new avenues for interventions in managing ME/CFS and highlights the importance of considering alternative treatment methods.

Potential effects on chronic fatigue
Treatment of multiple sclerosis with lofepramine, L-phenylalanine and vitamin B(12): mechanism of action and clinical importance: roles of the locus coeruleus and central noradrenergic systems.
We recently came across an intriguing study that highlighted the potential benefits of a combination therapy involving lofepramine, L-phenylalanine, and vitamin B12 for patients suffering from multiple sclerosis (MS). Conducted as a randomized, placebo-controlled double-blind trial, the research aimed to evaluate how this combination could help alleviate various symptoms associated with MS and chronic pain.
While this study did address the role of vitamin B12, it was examined alongside lofepramine and phenylalanine. This makes it challenging for us to pinpoint the specific impact of vitamin B12 in the context of chronic fatigue syndrome on its own. The treatment showed effectiveness in improving symptoms within just two to four weeks, but due to the combination of treatments, we need more focused studies to assess vitamin B12's distinct role.
Overall, it's exciting to see a potential link between this therapy and symptom relief, yet we must remain cautious about attributing the benefits solely to vitamin B12, given the blended approach of the therapy used in the trial.
After developing chronic fatigue syndrome with numbness due to poor posture, I sought a supplement. After a week of taking vitamin B12, my symptoms lessened significantly. Within a month, the numbness vanished, and I felt much better. If you face similar issues, I strongly recommend trying this supplement.

Struggling with chronic fatigue syndrome, I noticed a remarkable increase in my energy levels after taking this lozenge. It contains multiple B vitamins that work well together. The boost was both immediate and significant, making it a valuable addition to my health regimen.
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 B Complex refers to a group of water-soluble vitamins that play important roles in cell metabolism and overall health. This group typically includes eight essential vitamins: B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folate), and B12 (cobalamin). Each of these vitamins contributes uniquely to various bodily functions, such as energy production, red blood cell formation, and nervous system function. For instance, B12 and folate are crucial in preventing anemia, while B6 is vital for brain development and function.
Many people can obtain their daily requirements of B vitamins through a balanced diet that includes whole grains, meats, eggs, nuts, leafy greens, and dairy products. However, certain groups—like vegetarians, pregnant women, and older adults—may benefit from supplementation to meet their nutritional needs. It's important to consult with a healthcare professional before starting any supplement regimen, as excessive intake of certain B vitamins can lead to adverse effects. Overall, ensuring adequate intake of Vitamin B Complex is vital for maintaining energy levels and supporting overall health.
While there is no definitive cure for Chronic Fatigue Syndrome (CFS), some research suggests that Vitamin B Complex may play a supportive role in managing symptoms. The B vitamins, including B1, B2, B3, B5, B6, B7, B9, and B12, are essential for energy production and metabolic processes in the body. Many individuals with CFS report low energy levels and fatigue, which can be exacerbated by deficiencies in these vitamins. Supplementing with a B Complex may help improve energy levels, cognitive function, and overall well-being for some, although results can vary from person to person.
It's important to note that while B vitamins may be beneficial, they should not be viewed as a substitute for a comprehensive treatment plan. Consulting with a healthcare professional is crucial for personalized advice and proper diagnosis. Should you decide to try a Vitamin B Complex, look for high-quality products that include the full range of B vitamins and consider discussing with your doctor for tailored recommendations that complement any existing treatment strategies.
