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.

B12 and folic acid show promise
Response to vitamin B12 and folic acid in myalgic encephalomyelitis and fibromyalgia.
We aimed to evaluate how folic acid, in combination with vitamin B12, impacts individuals with chronic fatigue syndrome (CFS), also known as myalgic encephalomyelitis (ME). Our study focused on a group of 38 patients who had received weekly B12 injections for six months to several years.
During our research, we categorized the patients into two groups: Good responders and Mild responders, based on their improvement in symptoms. We found that those who responded positively had received B12 injections more frequently and at higher doses compared to those with lesser improvement. They also tended to use more folic acid daily and were less likely to use strong analgesics.
Our findings suggested a clear relationship between the dosage of B12 and folic acid and the degree of improvement reported by the participants. However, we noted a higher occurrence of fibromyalgia among those with milder responses, indicating that the presence of additional conditions might affect outcomes.
Overall, we observed a dose-response effect suggesting that B12 and folic acid together could bring about meaningful improvements in CFS symptoms. Also, we identified the importance of being aware of possible thyroid issues and highlighted the need for more precise research regarding their interaction with other medications.

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.
Unfortunately, this was an unsuccessful purchase for my chronic fatigue syndrome. While I was relieved there was no constipation, I experienced excitability and palpitations, which I believe were due to the excessive vitamin B12 dosage. It's crucial to be aware of what I’m consuming.

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.
Iron is a chemical element with the symbol Fe, derived from the Latin word "ferrum." It is a metal that is known for its strength and versatility, making it one of the most widely used materials in construction, manufacturing, and various industrial applications. Iron is the fourth most abundant element in the universe by mass and is primarily obtained through the mining of iron ores, such as hematite and magnetite. Once mined, it undergoes processes like smelting and refining to produce usable forms like cast iron, wrought iron, and steel.
In addition to its industrial uses, iron is also crucial for human health, as it plays a significant role in the production of hemoglobin, the protein in red blood cells responsible for transporting oxygen throughout the body. A deficiency in iron can lead to anemia, characterized by fatigue and weakened immunity. Overall, iron is a fundamental element that supports modern infrastructure and is vital for maintaining good health.
Chronic Fatigue Syndrome (CFS) is a complex and debilitating condition characterized by extreme fatigue that doesn’t improve with rest and may worsen with physical or mental activity. While there is ongoing research into the various underlying causes of CFS, iron supplementation may be beneficial in specific cases, particularly if a person has been diagnosed with iron deficiency anemia. Iron plays a crucial role in oxygen transport and energy production, so inadequate levels can exacerbate symptoms associated with fatigue. However, it's important to note that not everyone with CFS will have low iron levels, and unnecessary supplementation can lead to adverse effects, especially if the body's iron levels are already sufficient.
Before considering iron supplements, it is essential to consult with a healthcare provider who can evaluate iron levels through blood tests and assess your overall health status. They may recommend dietary changes or supplements based on your unique situation. Moreover, managing CFS often requires a multi-faceted approach that may include lifestyle adjustments, physical therapy, or cognitive behavioral therapy. Therefore, while iron can play a role for some individuals with CFS, it shouldn’t be seen as a standalone solution, and a personalized treatment plan is crucial for effectively managing this complex syndrome.
Based on user reviews, the timeframe for seeing results from this supplement for Chronic Fatigue Syndrome can vary significantly. Some users reported experiencing noticeable improvements as quickly as within a few days. For instance, one user mentioned feeling a change by the third day of taking the supplement, and their symptoms disappeared within a week (Read Review). In contrast, another user indicated that they observed benefits within the first week (Read Review), while someone else mentioned a more gradual change, noting significant improvements over a month (Read Review).
However, not all experiences were positive, with some users reporting adverse effects that did not alleviate their symptoms of fatigue (Read Review, Read Review). Overall, while many found quick relief, the time to notice benefits can depend on individual responses to the supplement.
Recent research has shed light on the potential benefits of certain supplements for individuals suffering from Chronic Fatigue Syndrome (CFS). For instance, a study involving iron supplementation indicated significant improvements in fatigue and overall wellbeing among iron-deficient patients, suggesting that addressing nutritional deficiencies may have a positive impact on CFS symptoms [1]. Additionally, folinic acid treatment showed promising results, with 81% of participants reporting noticeable improvements after supplementation, particularly in patients facing immune deficiencies related to Epstein-Barr virus [3].
Moreover, combinations of vitamin B12 and folic acid have been linked to meaningful enhancements in CFS symptoms, particularly for those who responded positively to higher dosages [2]. However, not all studies have yielded conclusive outcomes; for example, the effects of a combination of liver extract and folic acid showed no significant advantage over placebo [5]. Overall, while supplements like iron, folinic acid, and vitamin B12 demonstrate potential benefits for managing CFS, individual responses can vary, and further targeted research is essential to unravel their specific roles in symptom management.
Users have reported a wide array of improvements in their symptoms related to chronic fatigue syndrome after using this supplement. Many individuals highlighted significant reductions in fatigue and improvements in overall energy levels. For example, one user noted that their symptoms disappeared within a week of taking the product, marking a quick turnaround in health (Read Review). Another user mentioned feeling their mood improve in addition to experiencing enhanced energy levels, coupled with higher iron levels confirmed through blood tests (Read Review).
Moreover, several reports indicate that users were able to manage associated symptoms like dizziness and light-headedness effectively, finding relief from common side effects linked with iron supplements such as constipation and stomach discomfort (Read Review). While many experienced these positive outcomes, not all reviews were favorable—some users reported adverse reactions, including nausea and fatigue, suggesting that individual responses to the supplement can vary significantly (Read Review). Overall, while many felt substantial relief and improvements, personal tolerance and effectiveness of the supplement can differ greatly.
Users have mixed experiences when it comes to combining this iron supplement with others while managing Chronic Fatigue Syndrome (CFS). Several reviews indicate notable successes in symptom relief, particularly when the supplement is paired with additional nutrients. For instance, one user reported impressive outcomes after taking this supplement along with vitamin B12 and vitamin C, leading to improved energy levels and mood, alongside a recovery in iron levels as confirmed by blood tests (Read Review). Conversely, others highlighted the potential for adverse effects, with one user experiencing excitability and palpitations attributed to high vitamin B12 levels, prompting them to be cautious about what they consume (Read Review).
Additionally, users noted that when the supplement was taken on its own or with compatible ingredients, many found it gentler on the stomach and more effective in alleviating fatigue. A user praised its gentle formulation, emphasizing its effectiveness in relieving dizziness associated with low iron (Read Review). Some users successfully managed symptoms without alternative supplements, while others experienced gastrointestinal issues, underscoring that experiences can vary widely based on individual tolerance and specific supplement combinations (Read Review).
Users report varying experiences with iron supplementation for treating Chronic Fatigue Syndrome, often highlighting the importance of dosage and formulation. Several users like those of the Garden of Life Vitamin Code Raw Iron Vegan Capsules and other chelated iron products noted significant benefits, including increased energy, improved mood, and disappearance of chronic fatigue symptoms after just a few days or weeks of use (Read Review, Read Review). One user emphasized the importance of continuing treatment for three months to fully gauge its efficacy (Read Review).
Conversely, others experienced adverse reactions, such as nausea and fatigue, indicating that the right dose may vary by individual and formulation (Read Review, Read Review). Specific combinations, like iron with vitamin C and probiotics, were praised for enhancing absorption without causing gastrointestinal discomfort (Read Review, Read Review). A consistently gentle formula appears to be key for many users, as evidenced by reports of improved tolerance and effectiveness against fatigue symptoms.

Iron boosts fatigue symptoms
The Effect of Parenteral or Oral Iron Supplementation on Fatigue, Sleep, Quality of Life and Restless Legs Syndrome in Iron-Deficient Blood Donors: A Secondary Analysis of the IronWoMan RCT.
We explored the effects of iron supplementation on individuals suffering from iron deficiency, specifically looking at its impact on symptoms like chronic fatigue syndrome (CFS). This was done through a well-structured study involving 176 blood donors who were iron deficient, with a randomized controlled trial design.
Participants were assigned to receive either intravenous iron or oral iron supplements. Over an 8-12 week period, we assessed changes in symptoms related to iron deficiency, including CFS, restless legs syndrome (RLS), sleeping disorders, and overall quality of life.
The results indicated that iron supplementation may significantly improve the symptoms associated with iron deficiency among blood donors. By addressing the iron deficiency, we noted improvements not only in fatigue but also in wellbeing, confirming that targeted iron treatment can be beneficial for those struggling with chronic fatigue linked to low iron levels. This is an exciting finding for both clinicians and patients, shedding light on a relatively simple intervention that can enhance quality of life.

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.

No significant benefit from folate
Liver extract-folic acid-cyanocobalamin vs placebo for chronic fatigue syndrome.
We conducted a carefully designed study to investigate the effects of an injectable treatment combining bovine liver extract, folic acid, and cyanocobalamin on chronic fatigue syndrome (CFS). This involved a double-blind, placebo-controlled crossover trial with 15 patients who met definitive criteria for CFS.
Throughout the study, patients received both the treatment and a placebo in alternating phases. While we observed that both the treatment and placebo seemed to provide some improvement in functional status for the patients, our analysis showed no significant advantage of the liver extract and folic acid combination over the placebo.
This indicates that the response to folate, particularly, is unclear as the placebo effect appeared to be notably strong among participants. Overall, the findings suggest that further research may be needed to ascertain the definitive role of folate in managing chronic fatigue syndrome.
