Objective: To examine the efficacy and effect modifiers of folic acid supplementation in the prevention of stroke in regions without folic acid fortification based on relevant, up-to-date published randomized trials. Methods: Relative risk (RR) was used to measure the effect of folic acid supplementation on risk of stroke using a fixed effects model. Findings: Overall, folic acid supplementation significantly reduced the stroke risk by 11% (22 trials, n = 82,723; RR 0.89, 95% confidence…

TLDR
Evidence from observational genetic epidemiological studies, randomised controlled clinical trials, and evidence from established policies of population folate supplementation is concordant in suggesting an absence of benefit from lowering of homocysteine with folic acid for prevention of stroke.
Interaction of serum vitamin B12 and folate with MTHFR genotypes on risk of ischemic stroke
TLDR
Effect of folic acid treatment was greatest in patients with low folate and B12 with the CC genotype, and with high folate and B 12 with the TT genotypes, and the risk of first ischemic stroke was significantly higher in hypertensive patients.
Effect of long-term low-dose folic acid supplementation on degree of total homocysteine-lowering: major effect modifiers
TLDR
The degree of tH Cy reduction associated with long-term folic acid supplementation can be significantly affected by sex, MTHFR C677T genotypes, baseline folate, tHcy, eGFR levels and smoking status.
Estimated Stroke-Free Survival of Folic Acid Therapy for Hypertensive Adults
TLDR
Overall, besides significant benefit in certain subgroups, enalapril plus folic acid treatment for hypertensive patients is associated with a modest gain in lifetime stroke-free survival, compared with enalAPril alone.
The Role of Nutrition in the Risk and Burden of Stroke: An Update of the Evidence
TLDR
The Cochrane Library, PubMed, and MEDLINE using the search term stroke in combinations with the terms nutrition, diet, nutrients, foods, dietary patterns, risk, burden, epidemiology, randomised trial, systematic review, and meta-analysis for articles published between January 1, 2012, and June 1, 2017 found mainly articles published in the past 5 years.
Interaction of neutrophil counts and folic acid treatment on new-onset proteinuria in hypertensive patients
TLDR
Among hypertensive patients, those with higher neutrophil counts had increased risk of new-onset proteinuria, and this risk was reduced by 51% with folic acid treatment, and may serve as a biomarker to identify high-risk individuals who could particularly benefit from folic Acid treatment.
The current status of homocysteine as a risk factor for cardiovascular disease: a mini review
TLDR
A focused Medline search of the English language literature was conducted between 2010 and 2017 using the terms, homocysteine, risk factor, atherosclerosis, cardiovascular disease, stroke, treatment, and 38 papers with pertinent information were selected and there is a controversy regarding the significance of homocy steine as a risk factor for CVD and stroke.
Association Between Folate and Health Outcomes: An Umbrella Review of Meta-Analyses
TLDR
Current evidence allows for the conclusion that folate is associated with decreased risk of all-cause mortality and a wide range of chronic diseases, however, folate may be associated with an increased risk of prostate cancer.

Folic Acid Supplementation and the Risk of Cardiovascular Diseases: A Meta‐Analysis of Randomized Controlled Trials
TLDR
A greater benefit for CVD was observed among participants with lower plasma folate levels and without preexisting CVD and in studies with larger decreases in homocysteine levels, while folic acid supplementation had no significant effect on risk of coronary heart disease.
Folic acid for the prevention of colorectal adenomas: a randomized clinical trial.
TLDR
Folic acid at 1 mg/d does not reduce colorectal adenoma risk and is associated with higher risks of having 3 or more adenomas and of noncolorectAL cancers.
Lowered risks of hypertension and cerebrovascular disease after vitamin/mineral supplementation: the Linxian Nutrition Intervention Trial.
TLDR
It is indicated that supplementation with a multivitamin/mineral combination may have reduced mortality from cerebrovascular disease and the prevalence of hypertension in this rural population with a micronutrient-poor diet.
Efficacy of folic acid therapy in primary prevention of stroke among adults with hypertension in China: the CSPPT randomized clinical trial.
TLDR
Among adults with hypertension in China without a history of stroke or MI, the combined use of enalapril and folic acid, compared with en alapril alone, significantly reduced the risk of first stroke.
Dose-dependent effects of folic acid on blood concentrations of homocysteine: a meta-analysis of the randomized trials.
TLDR
The objectives were to ascertain the lowest dose of folic acid associated with the maximum reduction in homocysteine concentrations and to determine the additional relevance of vitamins B-12 and B-6.
Folic Acid-Based Intervention in Non-ST Elevation Acute Coronary Syndromes
TLDR
Folic acid-based supplementation is not beneficial and may even be harmful in the secondary prevention of cardiovascular events in patients with unstable angina and non-ST-elevation myocardial infarction and further studies on the safety of such supplements are suggested.
Effect of B-vitamin therapy on progression of diabetic nephropathy: a randomized controlled trial.
TLDR
Among patients with diabetic nephropathy, high doses of B vitamins compared with placebo resulted in a greater decrease in GFR and an increase in vascular events.
