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.

Vitamin B12 may improve arthritis
Vitamin B12 inhibits peptidylarginine deiminases and ameliorates rheumatoid arthritis in CAIA mice.
We investigated the effects of vitamin B12 on rheumatoid arthritis, particularly focusing on its impact on peptidylarginine deiminase isoform 4 (PADI-4), an enzyme linked to the disease's progression. Our study revealed that vitamin B12 effectively inhibited this enzyme more than another related enzyme, PADI-2, highlighting its potential as a therapeutic agent.
We observed that vitamin B12 treatment led to lower overall levels of citrullination, which is important since unregulated citrullination is a common issue in rheumatoid arthritis. Additionally, when hydroxocobalamin, a form of vitamin B12, was administered to mice, it significantly reduced the severity of arthritis symptoms in those with collagen type II antibody induced arthritis (CAIA).
Importantly, we found that vitamin B12 also decreased the expression of various pro-inflammatory factors and cytokines often elevated in rheumatoid arthritis, including IL17A, TNFα, and IL-6. These findings suggest that vitamin B12 may have a beneficial role in managing rheumatoid arthritis, warranting further exploration of its therapeutic potential.

Folate may alleviate knee OA
Association between folate intake and radiographic progression, pain function scores in subjects with radiographic knee osteoarthritis: Data from the osteoarthritis initiative.
Our exploration focused on understanding how folate intake might influence knee osteoarthritis (OA), particularly regarding pain relief and improved function. We examined data from a large population-based study of patients with prevalent knee OA to see if higher folate consumption could help manage their symptoms and slow disease progression.
We found that individuals who consumed more folate reported less knee pain and improved function over a 48-month period. Specifically, increases in folate intake were associated with notable decreases in the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores, which measure pain and disability in patients. For each additional 50 micrograms of folate consumed per 1000 calories, participants experienced a significant reduction in their pain and overall function scores.
Interestingly, our findings suggest that the benefits of folate are especially pronounced in certain groups, including men, older adults, those who are overweight or obese, and individuals with higher dietary fiber intake. This indicates that folate may play a vital role in managing knee OA symptoms effectively, offering a simple dietary adjustment that could lead to meaningful improvements in quality of life.
In summary, our study highlights the potential of folate to positively influence knee osteoarthritis by reducing pain and enhancing functional capabilities, making it a valuable addition to dietary recommendations for individuals suffering from this condition.

Folate intake reduces OA likelihood
Associations between nutrient intake and osteoarthritis based on NHANES 1999 to 2018 cross sectional study.
We explored how nutrient intake affects osteoarthritis (OA), with a particular focus on folate. Analyzing data from the National Health and Nutrition Examination Survey (NHANES) collected between 1999 and 2018, we looked at the dietary habits of over 32,000 participants to understand the associations between six key nutrients and OA.
Our research found that higher intake of dietary fiber, folic acid, and nicotinic acid was linked to a lower risk of OA. Specifically, we observed that those in the highest quartile of folic acid intake had about a 28% lower chance of having OA compared to those with the lowest intake. The relationship between folate and OA appeared to be linear, meaning as folate intake increased, the likelihood of OA decreased steadily.
On the other hand, protein intake showed a more complex, J-shaped relationship with OA, indicating that moderate protein consumption could offer the most protection against the condition. While carbohydrates and fat intake did not show a significant association with OA, our findings emphasize the importance of optimizing dietary choices to potentially reduce the risk of arthritis.

Folate-modified vesicles alleviate arthritis
Folic acid-modified ginger-derived extracellular vesicles for targeted treatment of rheumatoid arthritis by remodeling immune microenvironment via the PI3K-AKT pathway.
We explored how a type of plant-derived vesicle, specifically ginger-derived extracellular vesicles, can play a role in treating rheumatoid arthritis (RA), a painful autoimmune condition. Our main focus was on enhancing these vesicles with folic acid to improve their targeting abilities within swollen joints.
By attaching folic acid to these ginger vesicles, we created a new entity called FA-GDEVs. These are specially designed to latch onto M1 macrophages, the type of immune cells that contribute to inflammation in RA. In our in vitro studies, we observed that FA-GDEVs encouraged these inflammatory macrophages to shift towards a more healing M2 phenotype. This transformation occurs through the modulation of the PI3K-AKT pathway, a key mechanism in cellular signaling.
Our in vivo research further supported these findings, showing that FA-GDEVs localized effectively in inflamed joints and significantly alleviated the symptoms of RA. Overall, FA-GDEVs emerge as a promising new strategy for treating RA, combining safety, effectiveness, and affordability in rheumatology.

Folic acid reduces MTX withdrawal rates
Risk Factors Associated with Adverse Events Leading to Methotrexate Withdrawal in Elderly Rheumatoid Arthritis Patients: A Retrospective Cohort Study.
We explored the effects of folic acid supplementation in elderly patients with rheumatoid arthritis (RA) who are treated with methotrexate (MTX). In this large-scale study, involving 198 elderly individuals over a long period, we sought to identify the factors that might lead to MTX discontinuation due to adverse events (AEs).
Our findings revealed that around 23% of patients stopped MTX within five years, increasing to 51.7% by the fifteen-year mark. Notably, gastrointestinal issues were the most common AEs leading to withdrawal. However, we discovered that those taking higher doses of MTX (15 mg/week and above) faced a significantly increased risk of discontinuation.
The good news is that folic acid supplementation appeared to be protective against these adverse events, reducing the withdrawal risk considerably. This suggests that by prescribing lower doses of MTX alongside folic acid, healthcare providers could better manage arthritis symptoms in elderly patients while minimizing the potential for harmful side effects.
Excellent! This supplement is ideal for anyone with immune diseases. My mother suffers from rheumatoid arthritis, and it’s of high quality. It should not be cut.

Frequently Asked Questions
Arthritis is a general term that refers to inflammation of the joints, which can lead to pain, stiffness, and swelling. It encompasses over 100 different types, with osteoarthritis and rheumatoid arthritis being the most common. Osteoarthritis, often associated with aging, occurs when the cartilage that cushions the joints wears down over time. In contrast, rheumatoid arthritis is an autoimmune disorder where the body's immune system mistakenly attacks the joints, leading to chronic inflammation and potential disability if left untreated.
Symptoms of arthritis can vary widely depending on the type but typically include joint pain, swelling, reduced range of motion, and sometimes fatigue. Diagnosis usually involves a combination of physical exams, imaging tests, and blood tests. While there is currently no cure for arthritis, various treatments ranging from lifestyle modifications, physical therapy, and medications can help manage symptoms and improve quality of life. For those affected, seeking early diagnosis and intervention is crucial for slowing disease progression and preserving joint function.
Folic acid, also known as vitamin B9, is a water-soluble vitamin that plays a crucial role in many bodily functions, particularly in the synthesis of DNA and RNA. It is essential for cell division and is especially important during periods of rapid growth, such as during pregnancy and infancy. The body cannot produce folic acid on its own, which is why it must be obtained from dietary sources or supplements. Commonly found in leafy green vegetables, legumes, seeds, and fortified foods, folic acid is vital for preventing neural tube defects in developing fetuses and is often recommended for women of childbearing age.
In addition to its key role in pregnancy, folic acid contributes to the production of red blood cells and can help reduce the risk of certain types of anemia. Research has also suggested that adequate folic acid levels may be associated with lowered risk of heart disease and other health issues. Most health organizations recommend a daily intake of 400 micrograms for adults, with higher amounts suggested for pregnant women. Incorporating folate-rich foods into your diet, or considering supplementation, can help ensure you meet your folic acid needs.
Folic acid, a B vitamin, is often recommended for various health benefits, including its role in promoting healthy cell function and reducing the risk of certain diseases. However, when it comes to arthritis, the evidence supporting the supplementation of folic acid as a treatment is limited. While some studies suggest that folic acid might help reduce homocysteine levels, which are associated with inflammation, there isn't sufficient clinical proof that it can directly alleviate arthritis symptoms or contribute to joint health.
If you are considering folic acid as a supplement for arthritis management, it's essential to consult a healthcare provider first. They can provide guidance on appropriate dosages and whether folic acid is suitable for your specific condition. Meanwhile, maintaining a balanced diet rich in vitamins and minerals, alongside conventional arthritis treatments, is often recommended to enhance overall wellbeing.
