Vitamin B12 shows no benefit for depression

Based on 29 Researches

Alzahrani H. Assessment of Vitamin B12 Efficacy on Cognitive Memory Function and Depressive Symptoms: A Systematic Review and Meta-Analysis. Cureus. 2024;16:e73350. doi:10.7759/cureus.73350

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.

Knee Pain details

Folate linked to reduced knee pain

Liu Z, Chen Z, Wu Z, Tang M, Lin Y, et al. Associations between folate intake and knee pain, inflammation mediators and comorbid conditions in patients with symptomatic knee osteoarthritis. BMC Musculoskelet Disord. 2024;25:973. doi:10.1186/s12891-024-08095-5

We explored the relationship between folate intake and knee pain in patients suffering from knee osteoarthritis (OA) over a two-year period. In this insightful study, data was collected from participants enrolled in a rigorous clinical trial designed to assess the effects of vitamin D supplementation. While the original trial focused on vitamin D, our post-hoc analysis allowed us to dive into the potential benefits of folate on knee pain and related conditions.

Through the use of dietary questionnaires, we assessed the average daily folate consumption of participants. In addition to evaluating knee pain levels at various intervals, other factors such as inflammatory markers, muscle strength, and comorbidities were also monitored. Impressively, we found that increased folate intake was associated with reduced knee pain and lower levels of inflammatory substances known as adipokines.

Furthermore, individuals with higher folate consumption reported fewer comorbid conditions, suggesting that folate may indeed play a role in enhancing overall health for those dealing with knee OA. However, while our findings are promising, they highlight the need for further research to fully understand the extent of folate's impact in this context.

We investigated how a rumen-protected folic acid (RPFA) supplement affects the health and performance of beef steers. This study used a randomized design with 180 Angus-crossbred steers divided into different treatment groups.

Although we observed that RPFA increased plasma folate levels and improved certain growth metrics, the findings on liver abscesses were less pronounced. The percentage of livers without abscesses showed a tendency to improve with lower RPFA doses, but no significant benefits overall were found.

It's essential to note that vitamin B12 levels were low across all treatments, which might have influenced the outcomes related to RPFA effectiveness.

Vitamin B12 promotes sleep in rats

Based on 10 Researches

Chang HY, Sei H, Morita Y. Effects of intravenously administered vitamin B12 on sleep in the rat. Physiol Behav. 1995;57:1019.

We sought to determine the impact of vitamin B12 (VB12) on sleep patterns in rats, particularly considering its potential benefits for those struggling with insomnia. By giving rats a daily intravenous dose of VB12, we monitored their sleep using polysomnographic recordings over a four-day period.

During our observations, we noticed a significant increase in non-rapid eye movement (NREM) sleep on the second and third days of VB12 administration. Interestingly, REM sleep also showed a notable boost on the second day. The enhancements in sleep were particularly evident during the light period, indicating that vitamin B12 could play a role in promoting sleep at those times.

Additionally, we found that the rats receiving vitamin B12 exhibited serum levels that were 40 times higher than those in control rats, suggesting a robust absorption and impact of the vitamin. Overall, our findings indicate that administering VB12 peripherally does have positive effects on sleep in rats, especially during the light hours.

Folate treatment aids liver fat reduction

Based on 16 Researches

Huang C, Luo Y, Liu Y, Liu J, Chen Y, et al. DNA hypermethylation-induced suppression of ALKBH5 is required for folic acid to alleviate hepatic lipid deposition by enhancing autophagy in an ATG12-dependent manner. J Nutr Biochem. 2025. doi:10.1016/j.jnutbio.2025.109870

We investigated the effects of folic acid treatment on nonalcoholic fatty liver disease (NAFLD), a condition where excess fat builds up in the liver, often linked to obesity and insulin resistance. Our research revealed that giving folic acid to mice on a high-fat diet helped improve their glucose tolerance and insulin sensitivity, alongside reducing unhealthy fat levels in their liver cells.

By diving into the mechanisms, we discovered that folic acid works by changing the DNA methylation patterns that regulate the expression of a protein called ALKBH5. This reduction in ALKBH5 levels led to an increase in a specific type of RNA modification and subsequently boosted the production of a protein called ATG12, which is vital for autophagy – the process that cleans up and recycles cellular components.

When we inhibited ATG12 through overexpression of ALKBH5, autophagy was impeded, showcasing how crucial ATG12 is for allowing folic acid to effectively reduce fat accumulation in the liver. Overall, these findings indicate that folic acid could be a promising nutritional ally in fighting NAFLD, revealing a clear mechanism by which it protects liver health.

Folate micelles for tumor diagnosis

Based on 12 Researches

Upadhaya P, Hazari PP, Mishra AK, Dutta B, Hassan P, et al. Radiolabelled folate micellar carriers as proposed diagnostic aid for CNS tumors by nasal route. Drug Deliv Transl Res. 2023;13:2604. doi:10.1007/s13346-023-01341-8

We explored the potential of folate as a diagnostic aid for brain tumors, specifically targeting gliomas—some of the most challenging brain cancers. A key part of our approach involved developing a micellar delivery system that could be given through the nose. This method is less invasive and may provide a more effective way to reach brain tumors.

In our research, we took advantage of the fact that folate receptors are overexpressed in brain tumors, making them an excellent target for diagnosis. We synthesized a folate-conjugated agent, labeled it with technetium (Tc), and encapsulated it within micelles for improved delivery.

Testing revealed that these micelles had a safe profile for nasal administration in rats. In mice, the micelles demonstrated significantly better uptake in the brain compared to a standard folate solution. Imaging studies using specialized techniques showed that these micelles could effectively accumulate in brain tissue.

The findings suggest that this innovative formulation could not only help detect brain tumors but might also be applicable to other cancers that express folate receptors, such as those in the cervical, breast, and lung areas. Overall, we believe our approach has the potential to enhance cancer diagnosis in a fast, accurate, and non-invasive manner.

Folate's impact on gout therapy

Based on 5 Researches

Botson JK, Tesser JRP, Bennett R, Kenney HM, Peloso PM, et al. A multicentre, efficacy and safety study of methotrexate to increase response rates in patients with uncontrolled gout receiving pegloticase (MIRROR): 12-month efficacy, safety, immunogenicity, and pharmacokinetic findings during long-term extension of an open-label study. Arthritis Res Ther. 2022;24:208. doi:10.1186/s13075-022-02865-z

We explored the efficacy of methotrexate in conjunction with folate as a treatment approach for patients suffering from uncontrolled gout, specifically those using the medication pegloticase. The study aimed to understand how this combination therapy could enhance response rates and overall treatment success compared to pegloticase alone.

Patients involved in the study had high serum urate levels and struggled with urate-lowering therapy. Over a 12-month period, we observed that combining pegloticase with methotrexate and administering folate produced a significant responder rate of 79%. This was a noteworthy improvement over the 42% responder rate linked to pegloticase by itself.

While the study did highlight the benefits of using methotrexate, it also indicated that the specific contribution of folate was difficult to isolate. The results showed that the co-therapy was generally well tolerated, with patients experiencing sustained reductions in urate levels and fewer gout flares. Overall, the findings suggest that methotrexate may play a key role in increasing treatment response by reducing the formation of antibodies against pegloticase, yet we must remain cautious regarding the isolated benefits of folate alone in this context.

Folic acid reduces cholesterol risk

Based on 2 Researches

Qi J, Wu H, Chen H, Han W. Genetically predicted lipid traits mediate the association between folic acid and atherosclerosis. Sci Rep. 2024;14:19052. doi:10.1038/s41598-024-69728-2

We set out to understand how folic acid (FA) levels relate to high cholesterol and the risk of atherosclerosis, a leading cause of heart disease. Utilizing a method called Mendelian randomization, which leverages genetic data to uncover causal relationships, we explored the connection between genetically determined FA levels and atherosclerosis risk.

Our findings revealed that higher FA levels are linked to a lower risk of atherosclerosis. Specifically, we observed that individuals with greater FA levels had favorable cholesterol profiles—showing higher levels of good cholesterol (HDL-C) and lower levels of bad cholesterol (LDL-C) and triglycerides (TG). This suggests that FA might exert a protective effect on heart health by improving lipid levels.

Interestingly, we found that LDL-C, HDL-C, and TG together mediate a notable portion of this relationship, accounting for just over 13% of the total impact of FA on atherosclerosis. In simpler terms, improving cholesterol could be a significant part of how folic acid helps reduce heart disease risk.

Overall, this study emphasizes the importance of maintaining healthy folate levels, as it can be a vital step in reducing cholesterol and, consequently, lowering cardiovascular risks.

We explored how low levels of folic acid (FA) and Vitamin B12 (VB12) relate to high blood pressure (BP) in children and adolescents. Conducting both nested case-control and cohort studies, we focused on primary school participants. In our research, we found that children with elevated BP exhibited lower levels of FA and VB12 compared to those with normal BP.

Interestingly, overweight or obese children with high BP had even lower levels of FA than their counterparts with healthy BP. We also noticed a correlation between FA and healthy lipid profiles, suggesting that adequate FA could help in regulating blood pressure. After adjusting for VB12 levels and homocysteine, FA alone showed a significant relationship with elevated BP.

In the cohort study, we observed that participants with high FA levels consistently had lower systolic and diastolic BP levels compared to those with low FA levels. Our findings indicate that maintaining adequate levels of folic acid and vitamin B12 during childhood is crucial, not only through diet but also possibly via supplementation, to help prevent hypertension in the future.

We investigated the effects of folic acid on chronic inflammatory pain, especially in the context of arthritis. Adult rats were used in our study, and we induced inflammatory pain by injecting a substance called complete Freund's adjuvant (CFA) into their hind paws. Through behavioral tests, we assessed pain responses by measuring how long it took for the rats to withdraw their paws from painful stimuli.

Our findings showed that the CFA injections not only caused significant pain but also increased the expression of Matrix metalloproteinase 2 (MMP2), a protein associated with inflammation. Notably, MMP2 was primarily found in nerve cells rather than glial cells, indicating its crucial role in the pain pathway.

In an exciting twist, we discovered that long-term treatment with folic acid managed to reduce the overexpression of MMP2. This led to lasting relief from chronic inflammatory pain for the rats and also alleviated pain-related anxiety. These results suggest that folic acid could be a promising therapeutic option for managing chronic inflammatory pain and anxiety in arthritis patients, allowing for better pain management in the long term.

We explored the connection between folate metabolites and diabetic kidney disease (DKD), a serious complication that affects around 40% of individuals with type 2 diabetes. Our investigation drew on data from a large U.S. survey spanning nearly a decade, from 2011 to 2020, focusing on various forms of folate to see how they relate to DKD.

Through our research, we discovered that higher levels of total folate and 5-Methyl-THF were associated with a lower risk of DKD. Specifically, those in the highest quintile of these folate forms had an odds ratio (OR) of 0.73, indicating a protective effect. In contrast, certain other forms of folate, like RBC folate and UMFA, were linked to an increased risk of DKD, with ORs exceeding 1.4. This suggests that not all folate is beneficial when it comes to this condition.

Overall, our findings highlight the potential importance of promoting 5-Methyl-THF while minimizing UMFA for better diabetes management. It's clear that a balanced approach to folate intake could be crucial for maintaining kidney health in those with diabetes.

We explored the impact of vitamin B12 on rheumatoid arthritis, focusing on its ability to inhibit a specific enzyme known as PADI-4, which plays a key role in the disease's progression. Our findings suggest that vitamin B12 preferentially targets PADI-4 compared to another similar enzyme, PADI-2. This inhibition corresponds with a significant reduction in overall citrullination levels in cells, including histone H3 citrullination, which is relevant to the condition.

In our experiment, we utilized a specific model of arthritis in mice, known as collagen type II antibody-induced arthritis (CAIA). We administered hydroxocobalamin, a form of vitamin B12, and observed a marked improvement in the severity of arthritis symptoms in these mice. Moreover, the treatment led to a decrease in the expression of various inflammatory factors and cytokines associated with rheumatoid arthritis, such as IL17A, TNFα, and IL-6, as well as PADI-4 itself.

These findings indicate that vitamin B12 might represent a promising avenue for treating rheumatoid arthritis and warrant further investigation.

Bioprocess Biosyst Eng. 2025;48:121. doi:10.1007/s00449-024-03097-y

We explored the potential of a unique nanocomposite made from cerium oxide nanoparticles, folic acid, and carboxymethyl cellulose to combat breast cancer and drug-resistant bacterial infections. Using a green synthesis approach with Moringa oleifera, this study highlights how bimolecular combinations, especially those involving folate, might improve therapeutic effectiveness.

Our findings revealed that the folate-infused nanocomposite demonstrated significant antibacterial properties, particularly against Methicillin-resistant Staphylococcus aureus (MRSA), achieving a remarkable 95.6% effectiveness. This high level of activity is largely attributed to the production of reactive oxygen species (ROS) that inflict damage on bacterial cells. Furthermore, we noted promising anticancer effects against breast cancer cells, with the nanocomposite showing a lower inhibitory concentration than the cerium oxide alone.

It’s important to recognize that while folate is a key component, the full effect comes from its synergy with other compounds within this nanocomposite structure. Our research indicates that this innovative approach may offer new pathways for treatment in both bacterial resistance and cancer therapies, marking an exciting development in the field of nanomedicine.

Our findings revealed that vitamin B12 plays a crucial role in programming microglial cells—immune cells in the brain—helping them divide and activate effectively, which is vital during the healing process. This treatment appeared to improve the metabolism of these cells as well, promoting better functionality and reduced brain injury after a stroke.

Interestingly, we found that vitamin B12 significantly limited gene alterations associated with strokes in these microglia. Throughout the acute phase of an ischemic stroke, vitamin B12 altered the activities of different microglial subsets, leading to less brain damage and enhanced neurological recovery for the mice in our study. However, when we depleted microglia before administering the stroke, the beneficial effects of vitamin B12 disappeared, highlighting the importance of microglia in this process.

Overall, our research underscores the potential of vitamin B12 in mitigating neuroinflammation and aiding recovery for stroke victims. Through our preclinical studies, we've established that vitamin B12 may indeed offer a promising avenue for improving neurological outcomes post-stroke, meriting further exploration.

We observed five notable cases of acneiform eruptions linked to vitamin B12 in women aged 21 to 62. These eruptions manifested between one week and five months after starting vitamin B12 therapy.

The primary symptoms consisted of papules and pustules appearing mainly on the face. In three of the patients, these skin issues also extended to areas like the neck, shoulders, chest, and upper back, but interestingly, there were no signs of comedones or cysts.

Out of the five women, two had particularly high levels of vitamin B12 in their blood. A closer look at one patient's skin under a microscope revealed eosinophilic folliculitis, a type of inflammation in hair follicles. Fortunately, all patients experienced spontaneous and complete recovery within three to six weeks after stopping vitamin B12 treatment.

Overall, while vitamin B12 did not provide a benefit for acne treatment, it highlighted an unusual side effect of acne-like symptoms in these cases.

Examining Vitamin B12 in Autism

Based on 7 Researches

Erden S, Akbaş İleri B, Sadıç Çelikkol Ç, Nalbant K, Kılınç İ, et al. Serum B12, homocysteine, and anti-parietal cell antibody levels in children with autism. Int J Psychiatry Clin Pract. 2022;26:8. doi:10.1080/13651501.2021.1906906

We conducted a study that examined the levels of vitamin B12, homocysteine, and anti-parietal cell antibodies in children diagnosed with autism spectrum disorder (ASD) compared to a control group. Our research included 69 children, where 36 had ASD, and 33 were matched controls based on age, sex, and socioeconomic status. The severity of autism was assessed using the Childhood Autism Rating Scale (CARS), while serum levels were measured using a common laboratory technique called enzyme-linked immunosorbent assay.

Our findings revealed that children with ASD had significantly lower levels of vitamin B12 and homocysteine compared to their peers in the control group. However, we found no significant difference in the levels of anti-parietal cell antibodies, which suggests that vitamin B12 deficiency may not be due to absorption issues related to these antibodies. While we observed notable micronutrient deficiencies, it’s important to clarify that the study did not establish a direct benefit of vitamin B12 treatment for autism symptoms.

Importantly, this research hints at the potential role that vitamin B12 deficiencies may play in the clinical features of autism. Nonetheless, we believe that further studies involving larger populations are necessary to better understand how these micronutrient levels might influence the condition and its underlying causes.

We examined the connection between folic acid levels and stroke risk in a study involving nearly 5,000 individuals from a Chinese community. We discovered that participants with higher folate levels had a significantly lower risk of experiencing strokes.

Specifically, those in the highest folate group had a 32% lower risk of stroke compared to those with the lowest levels. We also found that homocysteine levels played a significant role in this relationship. Interestingly, the genetic variation of the MTHFR gene influenced how folate affected stroke risk, revealing a more complex interaction.

Heartburn details

Chourasia D, Misra A, Pandey R, Ghoshal UC. Gastric atrophy and intestinal metaplasia in a patient on long-term proton pump inhibitor therapy. Trop Gastroenterol. 2008;29:172.

We explored the case of a 74-year-old man who had been taking proton pump inhibitors for 20 years to manage symptoms of gastroesophageal reflux disease. Despite stopping his acid-reducing medications for a month, he showed an unusually high gastric pH level, indicating a significant decrease in stomach acidity. This condition may have led to gastric atrophy and intestinal metaplasia, as revealed through multiple biopsies of his stomach lining. Interestingly, after halting all anti-secretory drugs and starting only prokinetic treatment, the patient reported a significant improvement in heartburn symptoms.

During follow-up, although he developed symptoms of peripheral neuropathy—which were found to be related to a low level of vitamin B12—prompt treatment with vitamin B12 injections alleviated this issue. However, the correlation between improved heartburn symptoms and the vitamin B12 therapy is difficult to establish because the patient was also on prokinetics, which could have contributed to his symptom relief. Overall, our findings indicate that while vitamin B12 treatment offered benefits in this case, isolating its specific effect on heartburn remains challenging due to the combination therapy involved.

We explored the intriguing link between vitamin B12 deficiency and anemia, particularly through a rare condition known as pseudo-thrombotic microangiopathy. This condition mimics other thrombotic microangiopathies and could lead to unnecessary treatments such as plasmapheresis.

Our findings suggest that this situation should be taken seriously in patients showing signs of microangiopathic hemolytic anemia. It's essential to promptly administer vitamin B12 supplements in these cases, as it can effectively address the root cause of the anemia.

While the lab results may initially appear similar to conditions like thrombotic thrombocytopenic purpura, we noted important differences, particularly in the reticulocyte production index, which can help differentiate between these conditions. Overall, it emphasizes the importance of recognizing how vitamin B12 treatment can alleviate symptoms related to its deficiency.

We explored the use of ginger-derived extracellular vesicles modified with folic acid to treat rheumatoid arthritis, a painful autoimmune condition. By enhancing these vesicles to target the inflammatory cells in affected joints, we found that they help shift the immune response towards healing. Our in vitro and in vivo studies showed promising results: these folic acid-infused vesicles not only concentrated in the inflamed areas but also significantly reduced RA symptoms. This suggests that folic acid-modified vesicles could be a safe and effective alternative treatment option for RA.

We formulated a functional food product designed specifically for elderly individuals with Parkinson's disease, focusing on the common issue of constipation. Our approach involved creating a muffin recipe enriched with inulin, cacao, and Moringa, all of which play a role in supporting digestive health.

In this study, we conducted physical-chemical analyses to assess the nutritional components of the muffins, including soluble and insoluble fiber content. Our findings revealed a significant increase in fiber levels compared to control samples, which may alleviate constipation symptoms.

While we noted that the incorporation of inulin and cacao improved the muffins' nutritional value—particularly their dietary fiber and antioxidant properties—it’s essential to clarify that the specific role of folate, a nutrient present in these muffins, was not isolated in relation to constipation. However, the overall enhancements in fiber and nutrition could positively impact bowel health.

Sensory evaluations demonstrated a strong preference from participants, particularly for the muffins enriched with inulin and cacao, indicating potential acceptance of these products among the target population. Our study suggests that muffins fortified with these ingredients could be a practical dietary strategy to aid in managing constipation in individuals facing the challenges of Parkinson’s disease.

We conducted a study to examine the effectiveness of a vitamin B-containing ointment in treating mild-to-moderate plaque psoriasis compared to a standard glycerol-petrolatum-based emollient cream. The trial was designed thoughtfully, with 24 patients participating in a randomized, controlled, single-blind format. Each patient received the vitamin B ointment on one side of their body and the standard cream on the other side.

Over the duration of 12 weeks, we periodically measured the severity of psoriasis using the Psoriasis Area Severity Index (PASI). Our findings revealed that the vitamin B ointment significantly reduced the severity of psoriasis compared to the control cream at various times, particularly showing an impressive average reduction of 87.6% from baseline after 12 weeks.

This evidence suggests that vitamin B ointment not only offers a new treatment avenue for psoriasis but also should be considered in future treatment guidelines. We believe our research underscores the potential benefits of a vitamin B therapy approach in managing this chronic skin condition effectively.

We aimed to understand how treatments with folate in combination with tetracycline affect bloating in patients recovering from giardiasis. In a well-structured clinical trial, two groups received different treatments: one group was given a combination of albendazole and metronidazole for a week, while the other received tetracycline alongside folic acid for four weeks. The key focus was on symptom improvement, particularly bloating.

Both treatment groups noticed some reduction in overall symptoms by the end of the treatment period, with the tetracycline and folate group showing a more significant improvement. Notably, patients in both groups experienced a decrease in bloating, which is a common and uncomfortable symptom in gastrointestinal issues.

However, a month after the treatments, the number of patients reporting ongoing improvements was quite low. Additionally, symptoms, including bloating, returned over time, and by the end of the year, there was no lasting change in overall symptom scores for either group. This suggests that while folate and other treatments may provide short-term relief, they do not lead to long-standing benefits in managing persistent bloating following a Giardia infection. Ultimately, the reasons for ongoing bloating and discomfort remain unclear and deserve further investigation.

We aimed to understand how folic acid affects bone cancer pain, a challenging condition that isn't easily managed with typical treatments. In our study, we induced bone cancer pain in rats by injecting Walker 256 tumor cells into their tibia. To assess pain response, we measured how quickly they withdrew their paws in response to pressure and heat.

Throughout the study, we found that rats suffering from bone cancer pain showed a significant reduction in their pain thresholds. However, with continuous folic acid treatment, these thresholds improved, indicating a notable analgesic effect. We examined the levels of P2X2 and P2X3 receptors—known to play a role in pain signaling—and noticed they were elevated in the pain-afflicted rats. Remarkably, folic acid treatment resulted in a notable decrease in these receptors in both the spinal cord and relevant nerve ganglia.

This suggests that folic acid not only relieves pain but also acts by downregulating specific receptors associated with pain. We believe that our findings position folic acid as a promising option for alleviating bone cancer pain in clinical settings.

We explored the effectiveness of L-methylfolate, a form of folate, on alleviating dizziness, particularly in individuals with a specific genetic mutation. In one case, a patient experienced prolonged symptoms like headache, fatigue, and dizziness after taking terbinafine, known as Lamisil.

After conducting genetic tests, it was discovered that this patient was heterozygous for the C677T variation of the methylenetetrahydrofolate reductase (MTHFR) gene, which can affect how the body processes folate.

Fortunately, after prescribing L-methylfolate (Deplin), the patient's symptoms significantly improved. This reinforces the potential of L-methylfolate to help individuals with certain genetic predispositions, especially when medications interfere with the body's methylation cycle.

Overall, our findings suggest that for some patients, especially those with MTHFR mutations, treating dizziness with folate could be a promising avenue worth exploring further.

This cross-sectional study analyzed data from nearly 10,000 adults to investigate the link between dietary folate intake and severe headaches. We found that individuals with higher folate intake were less likely to report severe headaches. For example, those in the highest intake category showed a notable decrease in headache prevalence. Interestingly, this connection seemed especially relevant for women aged 20-50, suggesting they could benefit from increasing their folate consumption. Overall, while the findings indicate a potential protective effect of folic acid, they highlight the importance of a balanced diet for headache management.
