Vitamin B12 aids low back pain
Vitamin B12 in low back pain: a randomised, double-blind, placebo-controlled study.
Most Relevant Research
We conducted a thorough investigation to understand whether intramuscular vitamin B12 treatment could effectively relieve low back pain. This study was designed as a double-blind, placebo-controlled trial involving 60 patients aged 18 to 65 who suffered from mechanical low back pain or sciatic neuritis. Each participant had a history of back pain lasting from six months to five years and reported significant pain intensity according to a standard scale.

By comparing two groups—the one receiving vitamin B12 injections and the other receiving a placebo—we focused on measuring changes in pain and disability levels, as well as any changes in paracetamol consumption. What we found was quite impressive. Both groups reported decreases in pain and disability. However, those who received vitamin B12 showed significantly better results compared to the placebo group. The difference was not only notable in terms of pain relief but also in lower dependency on paracetamol for pain management.

Our findings confirm that vitamin B12 can be a safe and effective option for patients with low back pain, particularly for those who don't have any signs of nutritional deficiency. The data suggest that patients experiencing this common ailment could consider discussing vitamin B12 treatment with their healthcare provider as part of their pain management strategy.

Nitrous oxide affects B12 levels
Correlation Between Nitrous Oxide and Functional Vitamin B12 Deficiency Resulting in Subacute Combined Degeneration of the Spinal Cord: A Case Report.
Most Relevant Research
We examined a remarkable case involving the effects of nitrous oxide (NO) on vitamin B12 levels and its neurological consequences. Nitrous oxide is not just a useful tool in medical and food industries; it is sometimes misused by young adults for recreational purposes. This misuse can lead to functional vitamin B12 deficiency, which in turn may result in serious neurological issues like peripheral neuropathy and subacute combined degeneration (SACD) of the spinal cord.

In this specific case, we identified a functional B12 deficiency, characterized by borderline normal serum vitamin B12 levels, but with increased levels of methylmalonic acid and homocysteine—key indicators of vitamin deficiency. Remarkably, after administering intramuscular vitamin B12, we observed significant clinical improvement in the patient’s condition. This suggests that vitamin B12 treatment can be effective in reversing the neurological damage caused by nitrous oxide-induced deficiency.

Our findings highlight the importance of recognizing the neurological risks associated with nitrous oxide misuse and the potential for vitamin B12 treatment to alleviate serious symptoms in affected individuals.

Vitamin B12 improves chest pain
Pseudo-Thrombotic Microangiopathy Secondary to Vitamin B12 Deficiency.
Most Relevant Research
We observed an intriguing case involving a patient suffering from chest pain alongside severe anemia and vitamin B12 deficiency. The patient, a 44-year-old Hispanic woman, presented with escalating non-radiating chest pain, fatigue, and shortness of breath over three weeks. Her lab results showed critical pancytopenia and macrocytosis, raising concerns about a rare condition known as pseudo-thrombotic microangiopathy (TMA), which can occur due to vitamin B12 deficiency.

Initially diagnosed with pseudo-TMA, the patient was undergoing plasmapheresis and steroid treatment. However, once she received daily injections of 1000 micrograms of parenteral vitamin B, her condition began to improve significantly, leading to a resolution of her symptoms, including the chest pain.

This case highlights the importance of considering vitamin B12 deficiency in patients presenting with hemolytic anemia and chest pain. Often misdiagnosed as other conditions, patients may receive unnecessary treatments that delay the correct intervention. It’s vital to recognize the role of sufficient vitamin B12 in addressing specific symptoms like chest pain in such contexts.

Vitamin B12 ineffective for CFS
N of 1 trials. Managing patients with chronic fatigue syndrome: two case reports.
Most Relevant Research
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.

Vitamin B12 shows no benefit for depression
Assessment of Vitamin B12 Efficacy on Cognitive Memory Function and Depressive Symptoms: A Systematic Review and Meta-Analysis.
Most Relevant Research
We assessed the effect of vitamin B12 supplementation on depressive symptoms by reviewing several randomized controlled trials (RCTs). Our analysis focused on participants who may experience mild cognitive impairment, an area where low vitamin B12 levels could potentially raise the risk of depression.

After a thorough examination of studies, we found that the included trials did not support a significant benefit of vitamin B12 for alleviating depressive symptoms. In our evaluation of three studies focusing specifically on depression, the average difference in symptoms was negligible, indicating no real effect.

This outcome reflects that while vitamin B12 is essential for various bodily functions, its role in improving mood and reducing depression symptoms may not be as effective as some might hope. Further exploration is still warranted to better understand the contexts in which vitamin B12 could be beneficial.

Vitamin B12 improves eye movements
The Effectiveness of Steroid Versus Vitamin Therapy in the Improvement of Extraocular Movements in Patients With Diabetic Cranial Nerve Palsy: A Comparative Study.
Most Relevant Research
We explored the effectiveness of vitamin B12 in treating diabetic ocular nerve palsy, a complication that can occur in people with diabetes. In a recent study, fifty individuals with this condition were divided into two groups. One group received steroid treatments while the other was treated with vitamin B12 injections.

After assessing ocular movements at three points during treatment, we observed a notable improvement in those receiving vitamin B12 compared to those receiving steroids. Specifically, the vitamin B12 group showed an enhancement of eye movements by an average of 1.04, while the steroid group had a lesser improvement of 0.75. This difference was statistically significant, suggesting that vitamin B12 may be more effective in aiding recovery of eye movement in these patients.

Importantly, treating diabetic neuropathy with vitamin supplementation not only addresses possible nutritional deficiencies but could also improve overall quality of life for patients. This study highlights the potential benefits of vitamin B12 therapy, making it an appealing option for individuals dealing with the effects of diabetic-related nerve issues.

Vitamin B12 improves dizziness symptoms
Acute presentation of dizziness in vitamin B12 deficient old patient of cardiac disease: a case report.
Most Relevant Research
We observed a fascinating case involving an elderly patient who experienced acute dizziness, ataxia, and imbalance shortly after receiving a pacemaker. Upon investigation, we discovered that her symptoms were linked to a significant deficiency in vitamin B12.

The patient's vitamin B12 levels were notably low, accompanied by increased plasma homocysteine and methylmalonic acid levels. Despite her neurological symptoms suggesting peripheral neuropathy, her brain scan returned normal results. What stood out to us was the absence of the typical hematological signs often associated with vitamin B12 deficiency.

Importantly, the patient responded remarkably well to treatment with parenteral vitamin B12, leading to a resolution of her dizziness. This case underscores the importance of considering vitamin B12 deficiency, especially in elderly patients who present with neuropsychiatric symptoms. As we reflected on this, it became clear that proper recognition and treatment of vitamin B12 deficiency can significantly influence patient outcomes.

Vitamin B12 enhances acupuncture effects
[Observation of therapeutic effects on cervical vertigo treated with different methods].
Most Relevant Research
We explored the effectiveness of various treatments for cervical vertigo, specifically focusing on different acupuncture methods and the inclusion of Vitamin B12 in one of the therapy combinations. In our study, ninety-one participants were divided into three groups: one receiving routine acupuncture, another using electroacupuncture, and a third receiving a combination of electroacupuncture and Vitamin B12 injections along with local anesthetics.

Each therapy was administered over twenty sessions within a month. We measured changes in blood flow in the vertebral and basilar arteries and evaluated the participants' symptoms and overall function related to their vertigo. While all treatment methods showed some positive effects, the combination therapy, which included Vitamin B12, stood out as being the most effective.

This suggests that Vitamin B12 might play a significant role alongside acupuncture methods in treating cervical vertigo. However, it’s important to note that the specific impact of Vitamin B12 alone wasn’t isolated in this study, leaving us to consider its effects within the broader context of combined therapies.

Vitamin B12 effectively treats anemia
An Unusual Case of Hemolytic Anemia: A Case Report.
Most Relevant Research
We observed a compelling case surrounding the impact of vitamin B12 on anemia, particularly in a 62-year-old man facing severe deficiencies due to factors like drug use, hepatitis C, smoking, and alcoholism. Initially, this patient presented with symptoms such as fatigue, fever, and confusion, raising concerns about more critical conditions like thrombotic thrombocytopenic purpura (TTP). Laboratory tests indicated severe pancytopenia and signs of hemolysis, making the situation quite alarming.

However, further investigation revealed that the root cause was a significant deficiency of vitamin B12 coupled with folate. This discovery shifted our focus toward treatment strategies that addressed the underlying deficiency rather than applying unnecessary and invasive procedures like plasmapheresis. Upon administering vitamin B12 injections, we witnessed a refreshing turnaround as the patient's blood counts began to normalize progressively, along with an alleviation of symptoms.

This case emphasizes the necessity for healthcare providers to consider vitamin B12 deficiency when diagnosing patients presenting with hemolytic anemia and thrombocytopenia. By doing so, unnecessary treatments can be avoided, paving the way for a swift recovery through proper vitamin supplementation.

Vitamin B12 reduces cardiovascular risks
Association of MTHFR C677T, MTHFRA1298C, and MTRRA66G Gene Polymorphisms with Hyperhomocysteinemia and Its Modulation by the Combined Effect of Vitamin B12 and Folate in Chinese Population with Hypertension.
Most Relevant Research
We explored the connection between vitamin B12, genetic factors, and cardiovascular health in a group of Chinese adults suffering from hypertension. By analyzing the genetic variations of individuals, we aimed to understand how these may influence levels of homocysteine, an amino acid that can impact heart health when present in high amounts.

Our study included 1,304 participants over the age of 18. We measured their serum levels of vitamin B12 and folate, as well as their total homocysteine concentrations. The findings were quite significant: adequate levels of both vitamin B12 and folate were linked to lower homocysteine levels. This suggests that ensuring proper nutrition might be key to managing cardiovascular risks associated with high homocysteine.

We also noticed that the genotypic effects on homocysteine levels could be lessened with sufficient intake of these vitamins. Targeted nutritional interventions, such as increasing vitamin B12 and folate in the diet, could therefore play an essential role in heart health for those at risk. Our results emphasize the importance of nutrition in supporting cardiovascular health and managing hypertension.

Vitamin B12 helps heart recovery
Vitamin B12 alleviates myocardial ischemia/reperfusion injury via the SIRT3/AMPK signaling pathway.
Most Relevant Research
We explored how vitamin B12 can act as a safeguard against heart damage caused by ischemia/reperfusion (I/R) injury. In our study, we used a mouse model subjected to I/R injury by occluding the left anterior descending coronary artery, followed by 24 hours of reperfusion.

Our aim was to see if high doses of vitamin B12 could improve heart function and reduce damage. Through various evaluations, including echocardiography and biochemical methods, we revealed that vitamin B12 supplementation does indeed help. It mitigates oxidative stress and lowers levels of harmful reactive oxygen species.

Additionally, we found that B12 supplementation reduced cell apoptosis—essentially cell death—in heart tissues. This response was linked to the action of specific signaling pathways, particularly the SIRT3/AMPK pathway. However, we noted that these protective effects diminished when a SIRT3 inhibitor was introduced, indicating the importance of this pathway.

Moreover, RNA sequencing data showed that vitamin B12 also plays a role in reducing inflammation during I/R injury. Overall, our findings suggest that high doses of vitamin B12 might serve as an effective strategy for treating myocardial damage from I/R events, potentially paving the way for new therapies in heart health.

Methylcobalamin aids liver health
Methylcobalamin protects against liver failure via engaging gasdermin E.
Most Relevant Research
We explored how methylcobalamin, a form of vitamin B12, impacts liver disease, particularly in the context of cholestatic liver failure. The study utilized high-throughput screening to identify methylcobalamin as a specific inhibitor of gasdermin E (GSDME), a protein that plays a key role in pyroptotic cell death—a form of inflammatory cell death contributing to liver damage.

Our findings showed that when tested on mouse models with liver failure due to cholestasis, cisplatin, or concanavalin A, methylcobalamin effectively reduced liver damage. It significantly lowered liver transaminase levels, indicating less liver inflammation and cellular injury, and helped alleviate overall liver cell death.

Furthermore, methylcobalamin worked by preventing the cleavage of GSDME, which is essential for uncontrolled inflammatory cell death. By binding to a specific site on the GSDME protein, it blocked the interactions that trigger this damaging process. Overall, our study highlighted the potential of methylcobalamin as a promising therapeutic option for managing cholestatic liver failure and related conditions.

Vitamin B12 helps alleviate sciatica
Vitamin B12 in low back pain: a randomised, double-blind, placebo-controlled study.
Most Relevant Research
We conducted a double-blind, randomized, placebo-controlled study to explore the effectiveness of intramuscular vitamin B12 in treating low back pain, including cases of sciatica. A total of 60 patients between the ages of 18 and 65, all suffering from mechanical lumbago or sciatic neuritis, participated in the study over a period of time. Each patient had a solid medical history of back pain lasting from 6 months to 5 years, with significant pain intensity measured on a scale.

Throughout the study, both groups showed notable reductions in pain and disability. However, when we compared the active treatment with the placebo, the results favored vitamin B12 significantly; the differences were strikingly marked in measurement tools used for assessing pain and disability. Furthermore, the placebo group reported higher consumption of paracetamol compared to those receiving vitamin B12, indicating that this vitamin could effectively alleviate pain and the need for additional pain relief medications.

Overall, our findings support the potential of vitamin B12 injections in managing low back pain and sciatica for those without signs of nutritional deficiency.

Urinary excretion of homocysteine thiolactone and the risk of acute myocardial infarction in coronary artery disease patients: the WENBIT trial.
Most Relevant Research
In a recent study, we delved into the role of homocysteine thiolactone, a metabolite linked to heart disease, in predicting the risk of acute myocardial infarction (AMI). Conducted with a sizable group of 2049 patients suspected of having coronary artery disease (CAD), the trial was meticulously designed as a double-blind clinical intervention.

Participants were divided randomly into four distinct groups, receiving a combination of folic acid and other B vitamins or a placebo. Notably, we measured urinary levels of homocysteine thiolactone at different points throughout the study to draw correlations with heart attack incidents.

Our analysis revealed that while the homocysteine thiolactone/creatinine ratio was a significant predictor of AMI risk, there was no observable effect from the vitamin B treatments received by participants. This suggests that vitamin B12, when part of a group of B vitamins, did not independently influence the likelihood of having a heart attack.

Ultimately, we found that higher levels of homocysteine thiolactone correlated with a greater risk of AMI, but the combination of vitamin B treatments did not alter this outcome. This points to the potential of homocysteine thiolactone as an important marker in understanding cardiovascular health.

Vitamin B12 deficiency and migraines
The correlation between vitamin B12 serum levels and migraine: a case-control study.
Most Relevant Research
We examined the connection between vitamin B12 serum levels and migraine, both chronic and episodic. In our study, we compared two groups: 90 individuals suffering from migraines and 90 healthy participants. We measured the serum vitamin B12 levels of all subjects using a method known as enzyme-linked immunosorbent assay (ELISA).

Our findings showed that those with migraines had notably lower levels of vitamin B12 compared to the healthy control group. Specifically, chronic migraine patients had even lower serum vitamin B12 levels than those with episodic migraines. Additionally, we found a significant negative link between lower vitamin B12 levels and the severity of migraine attacks.

This indicates that individuals with vitamin B12 deficiency may experience more severe migraine symptoms. The results suggest a strong association between low vitamin B12 levels and migraines, pointing to a potential area for further research. We believe that exploring this relationship through interventional studies could offer valuable insights into migraine treatments.

Effects of dietary guidance on the symptoms, quality of life and habitual dietary intake of patients with irritable bowel syndrome.
Most Relevant Research
We examined how dietary guidance affects irritable bowel syndrome (IBS) symptoms and quality of life, particularly focusing on vitamin B12 intake. Our study involved 46 patients diagnosed with IBS based on established criteria, with 17 completing the entire program.

Through three sessions of personalized dietary advice, each lasting about 45 minutes, we found a significant reduction in IBS symptoms after the patients implemented the dietary changes. Their quality of life scores also improved notably. Although we noted an increase in vitamin B12 intake, it's important to emphasize that we did not isolate its effects from those of other dietary changes.

Interestingly, while our guidance helped patients enhance their overall nutrient intake, including vitamins and minerals, the increase in vitamin B12 specifically was the only change that reached statistical significance. However, we found no substantial differences in overall caloric or macronutrient intake among the participants.

In conclusion, while dietary guidance showed promising benefits for managing IBS symptoms and overall life quality, the impact of vitamin B12 alone remains unclear, as other dietary modifications may have played a role. Our findings suggest that individualized dietary counseling is a viable option in IBS management.

Reduced tinnitus
Most Useful Review
I took this for my tinnitus, and when combined with zinc, the high-pitched noise in my ears diminished significantly. The quality of the ingredients appears adequate, and the small capsules are easy to swallow, with no taste or odour. It is effective for early tinnitus and seems beneficial for the nervous system. Although it contains 180 tablets, I suggest repackaging them in a smaller bottle.

Vitamin B12 deficiency linked to migraines
The correlation between vitamin B12 serum levels and migraine: a case-control study.
Most Relevant Research
We conducted a case-control study to investigate the link between vitamin B12 serum levels and migraine, which affects so many people but lacks a fully understood cause. Our research included 90 individuals experiencing migraines—split into those with chronic migraines and those with episodic migraines—matched against 90 healthy participants.

We measured vitamin B12 serum levels using a reliable testing method and explored how these levels correlated with migraine intensity, as assessed by two measuring scales. Notably, we found that migraine sufferers had significantly lower levels of vitamin B12 compared to those without migraines.

Chronic migraine patients specifically had even lower vitamin B12 levels than their episodic counterparts. Additionally, there was a noteworthy negative correlation; as vitamin B12 levels decreased, the severity of migraine attacks increased. These findings suggest that vitamin B12 deficiency may have an important relationship with migraine experiences, emphasizing the need for further studies to explore this connection in detail.

Ineffective for pain
Most Useful Review
Disappointment 😞 It did not help with my pelvic pain like the Natural Factors brand at 5000 mcg. I took 10 capsules daily to match the dosage but found no relief. Even trying to dissolve the capsule under my tongue was unsuccessful.
