Folate supplementation and stroke preventionRevisiting cost-effectiveness of folic acid supplementation in primary stroke prevention in China: considering vitamin B12 deficiency masking issue.
High relevance to stroke prevention
We explored the cost-effectiveness of different folic acid supplementation strategies aimed at preventing strokes in hypertensive individuals in China. By examining four policy options, we aimed to find the best approach to support stroke prevention while considering potential complications from undetected vitamin B12 deficiencies.
The policies varied from simply not addressing folate levels to providing targeted folate supplements after screening for B12 deficiencies. Our analysis, based on a five-year intervention modeled from the China Stroke Primary Prevention Trial, found that the most effective strategy combined folate supplementation with screening for both folate and B12 deficiencies.
This combination not only helped prevent strokes but also ensured that those with B12 deficiency received appropriate treatment. The implications of this research suggest that adopting integrated screening approaches could greatly enhance public nutrition strategies, ultimately saving costs and improving health outcomes for at-risk populations.

We explored the connection between folate levels, homocysteine, and the outcomes of ischemic stroke. In a study involving 3,530 patients, we measured serum folate and homocysteine levels at the time of hospital admission.
Our findings revealed that higher folate levels were linked to a significantly lower risk of death and major disability three months after a stroke. Specifically, patients in the highest quartile of folate had a 29% reduced risk of experiencing adverse outcomes compared to those with the lowest levels.
On the flip side, elevated homocysteine levels seemed to indicate a higher risk; those in the top quartile had a 52% increased chance of facing the primary outcome. After adjusting for various factors, the results still highlighted that while folate may offer protective benefits, some of these effects might be mediated through homocysteine.
In summary, maintaining high levels of folate could be beneficial for stroke patients, potentially reducing their chances of serious complications.

Folic acid reduces stroke riskFolic acid supplementation for stroke prevention: A systematic review and meta-analysis of 21 randomized clinical trials worldwide.
Directly addresses folate and stroke
We explored the impact of folic acid supplementation on stroke prevention through an extensive look at 21 randomized clinical trials from around the world. This analysis involved over 115,000 participants, providing a comprehensive picture of how folate might influence stroke risk.
The findings revealed a noteworthy 10% reduction in stroke risk for those taking folic acid, suggesting that this vitamin plays a beneficial role in safeguarding against strokes. Interestingly, the effectiveness varied depending on whether the participants lived in areas where grains were fortified with folate. We observed a more significant impact in regions without fortified grains, highlighting that the local dietary context matters.
Furthermore, our analysis indicated that individuals without a prior history of stroke or heart issues experienced the most benefits from folic acid. These results emphasize the importance of individualized approaches to stroke prevention, considering both diet and personal health history. Overall, this substantial collection of trials supports the notion that folic acid could be a valuable component in stroke prevention strategies.

Tetrahydrofolate aids cognitive recoveryTetrahydrofolate Attenuates Cognitive Impairment after Hemorrhagic Stroke by Promoting Hippocampal Neurogenesis via PTEN Signaling.
High relevance to stroke treatment
We explored the impact of tetrahydrofolate (THF) on cognitive impairment resulting from intracerebral hemorrhage (ICH), a common type of hemorrhagic stroke. This research is particularly important because ICH can lead to cognitive challenges and significant psychological burdens for patients.
Our findings revealed that administering THF helps restore cognitive function after ICH. By using specially designed Nestin-GFP mice, we observed that THF not only spurs the growth of neural stem cells in the hippocampus but also promotes the creation of new neurons. This enhancement in neurogenesis is crucial for cognitive health.
On a mechanistic level, we discovered that THF reduces elevated levels of the protein PTEN, which is known to inhibit cell growth, while simultaneously increasing the levels of phosphorylated AKT and mTOR—proteins essential for cell survival and growth. Additionally, by conditionally removing PTEN from hippocampal neural stem cells, we noticed a reduction in the negative effects ICH typically has on the proliferation of these cells and on neurogenesis.
Overall, our study sheds light on the potential of THF as a therapeutic option for those recovering from hemorrhagic strokes, providing valuable insights into how we might help improve recovery for affected individuals.

We set out to explore how folic acid treatment influences stroke prevention, particularly in hypertensive people with specific genetic profiles and platelet characteristics. Using data from the China Stroke Primary Prevention Trial, we examined 11,185 adult patients, focusing on how factors like plateletcrit—a measure of how much of our blood is made up of platelets—interact with the MTHFR C677T genotypes, which are known to affect folate metabolism.
Our findings revealed that individuals with low plateletcrit and the TT genotype had the highest rate of strokes. This particular group, interestingly, showed a significant benefit from folic acid treatment, reducing their risk of a first stroke by 66%. Moreover, those with low plateletcrit alongside the CC or CT genotypes also experienced benefits from folic acid, showing a 60% reduction in stroke risk.
Therefore, assessing plateletcrit levels could be crucial for doctors in identifying patients who would gain the most from folic acid treatment. The study underscores the potential of folate in stroke prevention, particularly for individuals at a greater risk.

User Reviews
If you plan to conceive, ensure you check homocysteine. Methylfolate is an easily digestible form of vitamin B9. I took two capsules daily for two months, lowering my levels from 11.8 to 6.9. High homocysteine increases stroke risk, so I highly recommend this supplement!
This folic acid is excellent, especially for my mother after her stroke. It’s vital for maintaining blood vessel health in the brain!
This methyl folate is from a reputable firm, with adequate dosage. Though capsules are larger than tablets, they’re manageable to swallow. This form is better absorbed, benefiting those with absorption issues. Methyl folate can help lower the risk of strokes.
Maintaining stroke levels
Methylfolate is crucial to regulate homocysteine levels, as high levels can lead to stroke risks. I've opted for this form due to personal genetic factors, as there are few alternatives in Russia.
On my endocrinologist's advice, I started taking methyl folate while planning my pregnancy due to thyroid issues. It aided my quick conception and my uncle's swift recovery after his stroke, normalising his pressure and blood circulation.
