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.
No significant impact evaluated
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 relieves depressive symptoms
A new perspective on vitamin B12 deficiency in rheumatology: a case-based review.
High relevance to treatment effectiveness
We explored the impact of vitamin B12 supplementation on patients experiencing symptoms like depression, fatigue, and neuropathic pain—often linked with rheumatic diseases. Through our review of three case studies, we found that when these patients received vitamin B12 treatment, many of their depressive symptoms significantly improved.

The findings suggest that vitamin B12 may play a crucial role in alleviating not just physical discomfort, but also mental health issues like depression, which can accompany rheumatic conditions. Despite the patients initially presenting normal vitamin B12 levels in lab tests, the supplementation showed almost complete resolution of their symptoms, highlighting that clinical evaluations should not solely depend on blood test results.

In summary, we recommend that healthcare professionals consider assessing vitamin B12 levels early on when diagnosing rheumatic diseases and think about supplementation even if serum levels appear adequate. This approach might offer a straightforward and effective option for improving patients' quality of life.

Vitamin B6 effectively battles depression
Vitamin B6 Antidepressant Effects Are Comparable to Common Antidepressant Drugs in Bacillus-Calmette-Guerin Induced Depression Model in Mice.
Study directly evaluates vitamin B6
We explored the potential of vitamin B6 in treating depression, particularly how it compares to commonly used antidepressants. In our experiment, male mice were given a single dose of Bacillus-Calmette-Guerin (BCG) to induce depressive-like behaviors. Following this, we administered vitamin B6 alongside popular antidepressants such as fluoxetine, imipramine, and venlafaxine, to see how effectively each treatment mitigated symptoms over 14 days.

Our findings highlighted that vitamin B6 was effective in alleviating depression in the mice, just like the other antidepressant medications. The animals displayed significant improvements in both despair and anhedonia—key indicators of depression. Specifically, we noticed a decrease in immobility time during a forced swim test, indicating reduced despair. Plus, the latency to feed and food consumption improved significantly, showing that vitamin B6 helped counteract the depressive behaviors caused by BCG.

Overall, our research suggests that vitamin B6 can be a powerful ally in preventing depression, similar in effectiveness to some existing antidepressant drugs. We believe this opens the door for further clinical research on vitamin B6 as a potential treatment, especially for those at high risk for depression.

Brain fog relief
I've been using this for over a year and can't go without it. It was recommended to take methyl B to enhance the effectiveness of my depression medications. Initially, I didn't notice much change, but soon realised I felt better with this added. B12 has also helped alleviate my brain fog. It tastes good too.

Relief from depression
My favourite! This vitamin is part of the B complex vitamins. I think this is the best vitamin B12 as it is in the active form (methyl), and I really like this brand for also including methyl B9 and B6. I experienced several positive effects, mainly in pain relief and depression. The tablet is sublingual; just place it under the tongue, and it has a delightful taste. The dosage is great, and the bottle lasts a long time.

Mental health influences gastric cancer
Mental Health Conditions, Including Depression and Stress, Are Associated with Increased Odds of Gastric Cancer-Insights into the Role of Diet: A Case-Control Study.
Moderate relevance due to dietary interaction
We explored the connections between mental health conditions, like depression and stress, and the risk of developing gastric cancer. In this study, we looked at 82 patients with gastric cancer compared to 95 healthy individuals, measuring their mental health using a Depression-Anxiety-Stress Scale. We also examined what they ate through a food frequency questionnaire that included 168 items.

Our findings showed a notable association between depression and stress with higher odds of gastric cancer. Notably, when we analyzed dietary factors in relation to depression, we found that vitamin B6 had a protective effect. Specifically, in individuals experiencing depression, higher levels of vitamin B6 correlated with a significantly lower likelihood of facing depressive symptoms.

While this points to vitamin B6's potential benefits, it’s important to note that it wasn't tested in isolation from other dietary influences. Therefore, while we observed promising links between vitamin B6 and improved mental health, the impact of a diverse diet as a whole cannot be overlooked. Future studies are essential to better understand the specific impacts of nutrients like vitamin B6 on mental health and, subsequently, on conditions like gastric cancer.

Vitamin B6 helps prevent PPD
Can Vitamin B6 Help to Prevent Postpartum Depression? A Randomized Controlled Trial.
Highly relevant treatment investigation
We conducted a study to explore how vitamin B6 affects postpartum depression (PPD) among mothers who are at risk. This clinical trial took place in Isfahan, Iran, with 81 pregnant women participating over several months in 2016.

Our approach involved a single-blind, placebo-controlled design, where 40 women received 80 mg of vitamin B6 while 41 others were given a placebo from the 28th week of pregnancy until the end. We assessed the risk of PPD using various standardized questionnaires, including the Edinburgh Postpartum Depression Scale, both before and about 1.5 months after the supplementation.

After the intervention, we saw notable improvements. The depression scores dropped significantly in the group receiving vitamin B6, contrasting with the control group, which showed no improvement. This suggests that vitamin B6 may indeed play a protective role against PPD in women at risk.

With our findings, we believe that vitamin B6 could be a valuable tool in the prevention of postpartum depression for high-risk mothers, offering a simple dietary option that may enhance mental well-being during a critical time.

Vitamin B6 reduces depression in mice
Possible involvement of NO-sGC-cGMP signaling in the antidepressant like effect of pyridoxine in mice.
Directly assesses vitamin B6 effects
We explored the effects of vitamin B6, or pyridoxine, on depression in a study using mice. In this research, several doses of pyridoxine (12.5, 25, and 50 mg/kg) were administered to observe changes in behavior related to depression. Notably, we found that the highest dose of 50 mg/kg significantly reduced the immobility time in tests designed to measure depressive-like behavior, such as the tail suspension test and the forced swim test.

Our findings revealed an interesting mechanism behind these effects. Treatment with pyridoxine increased serotonin levels, a neurotransmitter often associated with mood regulation, while decreasing brain nitrite levels. However, we also examined the role of nitric oxide and its related pathway in enhancing pyridoxine's antidepressant effect. We noticed that certain substances, like L-Arginine (a nitric oxide donor) and sildenafil (which boosts cyclic GMP), seemed to counteract the positive effects of vitamin B6, while a nitric oxide/sGC inhibitor, methylene blue, amplified its benefits.

Overall, our study suggests that vitamin B6 could exert antidepressant-like effects by modulating serotonin levels in the brain and interacting with nitric oxide signaling pathways. This offers exciting potential for broader applications in managing depression, warranting further exploration in future studies.
