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 not isolated in study
Endothelial cell dysfunction in women with cardiac syndrome X and MTHFR C677T mutation.
We examined a group of 42 women suffering from chest pain but having normal coronary arteries, known as cardiac syndrome X. Our aim was to understand the link between a specific gene mutation (C677T) and abnormal homocysteine metabolism, a condition that may influence endothelial cell dysfunction, which has been tied to chest pain.
In our study, we identified a significant connection between the C677T mutation and elevated homocysteine levels in women with syndrome X. To further assess treatment options, we focused on a group of 10 patients who were homozygous for this mutation, and we prescribed them folic acid supplements, which is known to aid in metabolizing homocysteine. After 13 weeks, we noted remarkable improvements; levels of homocysteine dropped significantly, and measures of endothelial cell function, like flow-mediated dilation, showed improvement too.
Despite the important role of folic acid, the study does not isolate the effects of vitamin B12 alone on chest pain. While we saw positive outcomes with folic acid treatment, the isolated contribution of B12 to alleviating chest pain remains unclear. Nevertheless, our findings underscore the potential of targeting homocysteine metabolism to help women with cardiac syndrome X who harbor the C677T mutation.

Effects of vitamin B12 treatment
[Two cases of pulmonary thromboembolism associated with protein C and protein S deficiency and literature review].
We explored the effects of vitamin B12 treatment in two young male patients with pulmonary thromboembolism associated with protein C and protein S deficiencies. Both patients experienced a range of symptoms including chest pain, alongside lower limb pain and visual disturbances. Their diagnosis came after imaging tests revealed deep venous thrombosis and subsequent pulmonary embolism.
In the course of treatment, we noticed that the patients exhibited poor responses to standard anticoagulant therapies. To tackle this, vitamin B6 and B12 were introduced as part of their regimen. Remarkably, upon adding vitamin B12, we observed significant improvement in the patients' symptoms, such as reduced chest pain.
These findings suggest that vitamin B12 may play a beneficial role in managing symptoms of chest pain linked to this type of thromboembolic event, particularly in patients with underlying deficiencies. It’s important we recognize congenital thrombophilia when dealing with such cases, especially in younger individuals with unexplained recurrent complications before the age of 40.

Seven months into taking vitamin B12 for severe sciatica, I noticed a remarkable reduction in pain after four months, and now it’s completely gone! The pain from my herniated disc had been debilitating for nearly two years. I always take it after meals, and its small size makes it easy to swallow. I recommend it to anyone experiencing nerve pain.
We explored a case involving a 46-year-old woman who experienced chest pain and hemoptysis, leading to the discovery of a pulmonary thromboembolism. Upon further evaluation, we found that her homocysteine levels were high and that she had low vitamin B12 and iron levels due to pernicious anemia.
Although she was diagnosed with multiple conditions, including pernicious anemia and iron-deficiency anemia, an interesting aspect of her treatment was the supplementation with vitamin B12 along with other necessary nutrients like pyridoxine, thiamine, folic acid, and iron. At the end of the therapy, not only did her vitamin B12 and folate levels return to normal, but also her homocysteine levels and red cell volume improved.
Ultimately, repeat imaging showed that the thrombus had completely resolved, suggesting a comprehensive approach to her treatment was effective. While vitamin B12 was part of her therapy, it was combined with several other treatments. Therefore, it is challenging to isolate its specific impact on her initial chest pain.
In summary, our findings point toward vitamin B12’s potential role in addressing underlying causes of hyperhomocysteinemia, but its direct effect on chest pain remains less clear-cut given the multifaceted treatment she received.

Vitamin B12's effect on angina
Hyperhomocysteinemia and methylenetetrahydrofolate reductase polymorphism in a patient with coronary artery disease and repetitive miscarriages.
We explored the case of a 53-year-old woman with stable angina, who also experienced three unexplained first-trimester miscarriages. Her health evaluations revealed moderate hyperhomocysteinemia attributed to a genetic mutation known as MTHFR C677T. This condition, along with factors like abdominal obesity and post-menopausal status, raised concerns about her cardiovascular and reproductive health.
The patient began a treatment regimen that included vitamins B6, B12, and folic acid, alongside standard angina therapy. Notably, two months into this treatment, her homocysteine levels decreased by 28.6%, and there was a reported improvement in her overall clinical condition. However, it’s important to note that while vitamin supplementation showed effectiveness in lowering homocysteine levels, current evidence doesn’t strongly support that this leads to a significant reduction in cardiovascular events.
As we consider the role of vitamin B12 in treating chest pain, we recognize the complex relationship between homocysteine levels and cardiovascular health. While the vitamin may contribute positively to certain health outcomes, its isolated effect in preventing chest pain remains unclear and needs more research.

Chest pain is a broad term that refers to discomfort or pain felt in the chest area, and it can arise from a variety of causes. It can range from a sharp, stabbing sensation to a dull ache or pressure. Some common causes of chest pain include heart-related issues, such as angina or heart attacks, as well as non-cardiac conditions like acid reflux, musculoskeletal problems, or anxiety. Since chest pain can represent a serious condition, especially if it is sudden and severe, it's crucial to pay attention to accompanying symptoms such as shortness of breath, sweating, or nausea, which may warrant immediate medical attention.
If you're experiencing chest pain, it's essential to consult a healthcare professional for an accurate diagnosis. They may perform tests such as an electrocardiogram (ECG), blood tests, or imaging studies to determine the underlying cause. Early identification of heart-related issues can be life-saving, while non-cardiac causes, though often less serious, still require appropriate assessment and treatment. Understanding the context and quality of the pain can help guide that conversation with your doctor, ensuring you receive the best care possible.
Vitamin B12, also known as cobalamin, is a water-soluble vitamin that plays a crucial role in several vital functions in the human body. It is essential for red blood cell formation, neurological function, and DNA synthesis. Naturally occurring in animal products, the vitamin can be found in high concentrations in meat, fish, eggs, and dairy, making it particularly important for those following a vegetarian or vegan diet, as plant-based sources of B12 are limited and often require supplementation.
A deficiency in vitamin B12 can lead to serious health issues, including anemia, fatigue, memory problems, and nerve damage. Due to its significance, it's crucial for individuals, particularly those at risk of deficiency, to ensure adequate intake through diet or supplementation. For most adults, the recommended daily allowance (RDA) is around 2.4 micrograms, though pregnant or breastfeeding women may require higher amounts. If you're considering B12 supplements, it's advisable to consult with a healthcare provider to determine the best option for your specific needs and health status.
Based on user reviews, the time it takes to see results from taking B12 supplements for conditions such as chest pain can vary significantly. Some users report experiencing relief within just a few days; for instance, one reviewer noted dramatic easing of back pain after just three days of daily B12 supplementation Read Review. Others have indicated that it took a longer duration to observe significant improvements, such as several weeks or even months. A user dealing with severe sciatica experienced remarkable pain reduction after four months of consistent use Read Review.
There are also accounts of gradual improvement, where pain began to ease a couple of weeks into usage, such as one individual who reported that pain from shingles disappeared about two weeks after starting nightly doses of B12 Read Review. Therefore, while some may experience quick results, others may need to commit to several weeks before noticing a substantial benefit. It is crucial to monitor how your body responds and consult with a healthcare professional for personalized advice.
While vitamin B12 has been explored in relation to chest pain, the evidence supporting its efficacy remains inconclusive. Several studies have reported individual cases where vitamin B12 treatment appeared to improve symptoms associated with conditions that can lead to chest pain, such as pernicious anemia and thromboembolism [5], as well as pseudo-thrombotic microangiopathy [1]. However, these instances often involve complex clinical scenarios where multiple treatments are administered, making it difficult to isolate the effect of vitamin B12 alone.
Furthermore, a randomized study evaluating vitamin B12 and folic acid in patients with stable angina found no significant benefits in alleviating chest pain or modifying cardiovascular risk markers [3]. Similarly, while some studies have suggested a link between elevated homocysteine levels and chest pain, the specific role of vitamin B12 in providing relief remains ambiguous [4]. Overall, while there are cases indicating potential benefits of vitamin B12 in managing certain conditions associated with chest pain, scientific consensus regarding its direct effectiveness is lacking, necessitating further research to establish any definitive claims.
Many users have reported significant improvements in their symptoms after starting B12 supplementation, particularly for conditions involving nerve pain and discomfort. One user experiencing cervical spondylosis myelopathy noted a substantial reduction in neck and shoulder pain, along with a decrease in finger numbness within just a month of taking B12 Read Review. Similarly, another individual shared that their pain and numbness in the thigh nearly disappeared after using B12 for a short period, following surgery related to a cerebral aneurysm Read Review.
Others have experienced more gradual relief. For example, one user suffering from severe sciatica reported complete pain relief after four months of B12 use, a stark improvement from a painful condition that had persisted for nearly two years Read Review. Another account detailed how shingles-related pain eased and eventually disappeared about two weeks into nightly B12 intake Read Review. While the results varied among users, overall feedback indicates that B12 can be beneficial for nerve-related pains and symptoms, although it is essential to remember that individual experiences can differ widely.
Users who combined vitamin B12 supplements with other medications or supplements reported varying degrees of improvement in their conditions. One reviewer indicated that taking B12 alongside Metgluco, a medication for diabetes, helped in addressing their back pain significantly, highlighting the role of B12 in managing potential deficiencies caused by diabetes medication Read Review. Another user noted that B12 was effective for easing pain associated with peripheral neuropathy, suggesting its compatibility and effectiveness when used in conjunction with other treatments for neurological issues Read Review.
Conversely, not all users found success with B12 alone, with some reporting minimal relief despite high dosages or using sublingual methods Read Review. This illustrates that while B12 may enhance treatment for nerve pain when combined with other medications, individual experiences can vary widely, and B12 may not work for every user depending on their specific health conditions and existing treatments.
The optimal dose of vitamin B12 for treating chest pain appears to be around 1000 micrograms administered via daily injections, based on a specific case study involving a patient who presented with both chest pain and vitamin B12 deficiency ([1]). This case highlighted that the patient's condition improved significantly after receiving this regimen, suggesting that adequate vitamin B12 can potentially help alleviate symptoms like chest pain when associated with deficiencies.
However, it’s important to note that while this particular treatment protocol showed positive results, the broader effectiveness of vitamin B12 in treating chest pain remains inconclusive across various studies. In different scenarios, such as patients with stable angina or those undergoing angioplasty, vitamin B12 supplementation did not yield significant improvements in chest pain or other cardiovascular risk markers ([3]). As always, consult a healthcare professional before starting any new treatment to ensure it aligns with your specific health needs.

No significant benefit on chest pain
Effect of folic acid supplementation on levels of circulating Monocyte Chemoattractant Protein-1 and the presence of intravascular ultrasound derived virtual histology thin-cap fibroatheromas in patients with stable angina pectoris.
We evaluated the effects of folic acid and vitamin B12 supplementation on patients experiencing stable angina pectoris, a condition often associated with chest pain. In this randomized study, 102 patients underwent percutaneous coronary intervention and were divided into two groups: one received vitamin treatment while the other received a placebo.
After one year of treatment, we discovered that those taking folic acid and vitamin B12 did not show any significant difference in their levels of Monocyte Chemoattractant Protein-1 (MCP-1) or the presence of thin-cap fibroatheromas (VH-TCFA), which can signal unstable plaque in arteries. The average MCP-1 levels were similar between both groups, suggesting that vitamin B12, when used alongside folic acid, did not effectively alleviate chest pain or modify important markers of cardiovascular risk.
Additionally, we found that MCP-1 levels were higher in patients with VH-TCFA lesions, indicating a connection to increased future risk of myocardial infarction. Our follow-up period showed that a small percentage of patients experienced a heart attack, further supporting the idea that vitamin B12’s role in treating chest pain remains unproven in this context.
Overall, our findings suggest that while vitamin B12 was studied, its effect on chest pain cannot be firmly established due to the lack of notable benefits observed in conjunction with folic acid treatment.
