In patients with MTHFR (methylenetetrahydrofolate reductase) mutations and hyperhomocysteinemia, recurrent pregnancy loss is a frequent feature. The aim of the study was to evaluate the impact of folic acid, vitamins B6 and B12 supplementation for the lowering of total homocysteine concentrations and pregnancy. 16 patients who had had 3 or more miscarriages and MTHFR mutations were used in the study. They received methylfolate (5mg/day), vitamin B6 (50mg/day) and vitamin B12 (1mg/week). Supplementation induced a decrease in homocysteine from 19...

As many patients turn to vitamins and supplements to enhance energy, relieve fatigue, or generally feel better, it is important to understand the connection between the B vitamins and psychiatric symptomatology. Vitamins B6, B8, and B12 have been shown not only to reduce psychiatric symptoms but also shorten the duration of illness. Vitamin B9, also known as folate or folic acid, has also been associated with psychiatric symptoms. However, when patients lack a specific genetic enzyme, which converts folate/folic acid to its most usable form, L-methylfolate, the neuroprotective and neuropsychiatric benefits are lost...

Gerald Martone
People suffering from depression, schizophrenia, and dementia often have measurably lower levels of serum folate compared to people not experiencing psychiatric disorders. Augmentation of SSRI and SNRI antidepressant medications with l-methylfolate has been demonstrated to increase their effectiveness and onset of action. Even the use of l-methylfolate as a stand-alone monotherapy has been observed to exert antidepressant properties. The role of folate in mental illness has been known for many decades, but the strategic use of l-methylfolate supplementation has not yet been accepted as a standard regimen...

Folic acid supplementation confers modest benefit in schizophrenia, but its effectiveness is influenced by common genetic variants in the folate pathway that hinder conversion to its active form. We examined physiological and clinical effects of l-methylfolate, the fully reduced and bioactive form of folate, in schizophrenia. In this randomized, double-blind trial, outpatients with schizophrenia (n=55) received l-methylfolate 15 mg or placebo for 12 weeks. Patients were maintained on stable doses of antipsychotic medications...

Errors in folate metabolism may play a role in the pathology of autism spectrum disorders because of increased vulnerability to oxidative stress. We report a case where L-methylfolate supplementation improved symptoms of aggression and disruptive behavior in a child with autism who tested positive for the C677TT allele of the methyltetrahydrofolate reductase enzyme gene. To our knowledge, this is the first report of L-methylfolate administration in this situation. Further controlled studies of L-methylfolate in this population are warranted...

Two new simple and selective assay methods have been presented for the analysis of Escitalopram Oxalate (ESC) and L-Methylfolate (L-MF) in pharmaceutical formulations. The ultraviolet (UV)-Spectrophotometric simultaneous equation method was based on the measurement of absorbance at 238 nm (ʎmax of ESC) and 284 nm (ʎmax of L-MF) in methanol. The assay was linear over the concentration ranges 0.5-12.0 μg/mL for ESC and 0.5-9.0 μg/mL for L-MF. The quantitation limits for ESC and L-MF were found to be 0.912 and 0...

OBJECTIVES: The aim of this paper is to detail a summary of the current evidence in this area, to better inform clinical practice. Our recent systematic reviews and meta-analyses of nutrient pharmacotherapies in the treatment unipolar depression revealed primarily positive results for replicated studies testing S-adenosyl methionine (SAMe), methylfolate, omega-3 (EPA or ethyl-EPA), and Vitamin D; with supportive isolated studies found for creatine and an amino acid combination. Mixed results were found for zinc, folic acid, Vitamin C, and tryptophan; and non-significant study results for inositol...

BACKGROUND: L-methylfolate is a compelling candidate to treat bipolar I major depressive episodes. While approved as an adjunct for unipolar major depressive disorder, no studies have been done to assess the tolerability, safety, and efficacy of L-methylfolate for bipolar depression. As a first step, we developed a registry of bipolar patients treated with L-methylfolate to examine tolerability and outcomes. METHODS: Subjects (N=10) received treatment as usual plus daily L-methylfolate 15mg for 6 weeks in this open-label registry...

The methylfolate trap, a metabolic blockage associated with anemia, neural tube defects, Alzheimer's dementia, cardiovascular diseases, and cancer, was discovered in the 1960s, linking the metabolism of folate, vitamin B12, methionine and homocysteine. However, the existence or physiological significance of this phenomenon has been unknown in bacteria, which synthesize folate de novo. Here we identify the methylfolate trap as a novel determinant of the bacterial intrinsic death by sulfonamides, antibiotics that block de novo folate synthesis...

We examined whether using a medical food therapy for hyperhomocysteinemia (HHcy) in patients with Alzheimer's disease (AD) or cognitive impairment due to cerebrovascular disease (CVD) with Cerefolin®/CerefolinNAC® (CFLN: L-methylfolate, methylcobalamin, and N-acetyl-cysteine) slowed regional brain atrophy. Thirty HHcy patients with AD and related disorders (ADRD) received CFLN (HHcy+CFLN: duration [μ ±  σ] = 18.6±16.1 months); a sub-sample of this group did not receive CFLN for varying periods of time (HHcy+NoCFLN: duration [μ ±  σ] = 12...

The 5,10-methylenetetrahydrofolate reductase (MTHFR) gene plays a central role in folate metabolism. Many studies have demonstrated an association between MTHFR C677 T variant with depression, schizophrenia and bipolar disorder as one of them being comorbid to other. This has justified the use of folate supplement in psychiatric disorders mainly depression but still not in various other comorbid complex psychiatric disorders. Here we have tried to show how the l-methylfolate in conjunction with the conventional psychotropic drugs can be useful in a state of such complex psychiatric phenomenon and comorbid diagnosis with genetic polymorphism of MTHFR C677 T mutation...

OBJECTIVE: There is burgeoning interest in augmentation strategies for improving inadequate response to antidepressants. The adjunctive use of standardized pharmaceutical-grade nutrients, known as nutraceuticals, has the potential to modulate several neurochemical pathways implicated in depression. While many studies have been conducted in this area, to date no specialized systematic review (or meta-analysis) has been conducted. METHOD: A systematic search of PubMed, CINAHL, Cochrane Library, and Web of Science was conducted up to December 2015 for clinical trials using adjunctive nutrients for depression...

Cilioretinal artery occlusion is a cause of sudden, often catastrophic loss of central vision. There are no established effective treatments. Recently, a patient presented 24 hours after a cilioretinal artery occlusion, following a cardiac catheterization prior to which her blood thinners had been discontinued. Lacking an effective way to address the severe retinal ischemic oxidative stress, she was offered, under compassionate use, a multivitamin complex designed to address retinal ischemia and oxidative stress...

Folate-mediated one-carbon metabolism is an important therapeutic target of human diseases. We extensively investigated how gene-nutrient interactions may modulate human cancer risk in 2 major folate metabolic genes, MTHFR and GNMT. The biochemical impacts of MTHFR and GNMT on methyl group supply, global DNA methylation, nucleotide biosynthesis, DNA damage, and partitioning of the folate dependent 1-carbon group were carefully studied. The distinct model systems used included: EB virus-transformed lymphoblasts expressing human MTHFR polymorphic genotypes; liver-derived GNMT-null cell-lines with and without GNMT overexpression; and HepG2 cells with stabilized inhibition of MTHFR using shRNA, GNMT wildtype, heterozygotous (GNMT(het)) and knockout (GNMT(nul)) mice...

OBJECTIVE: Current therapies for diabetic peripheral neuropathy with pain mask the painful symptoms while the underlying pathology continues to progress. This study assessed changes in symptoms and quality of life in patients taking a novel prescription medical food, L-methylfolate-methylcobalamin-pyridoxal-5-phosphate (LMF-MC-PP, Metanx ), intended to address the underlying metabolic needs of patients with diabetic peripheral neuropathy. RESEARCH DESIGN AND METHODS: Between November 2010 and April 2012, patients rated their experiences before and after using LMF-MC-PP through an automated telephone system that included symptomatic items from the Neuropathy Total Symptom Score-6 (NTSS-6) questionnaire and questions related to quality of life and medication satisfaction...

In addition to its role in the endogenous synthesis of cysteine, cystathionine gamma-lyase (CGL) is a major physiological source of the vasorelaxant hydrogen sulfide. Cgl null mice are potentially useful for studying the influence of this compound upon vascular tone and endothelial function. Here, we confirm a previous report that female Cgl null mice exhibit an approximate 45-fold increase in plasma total homocysteine compared to wild type controls. This level of homocysteine is approximately 3.5-fold higher than that observed in male Cgl null mice and is essentially equivalent to that observed in mouse models of cystathionine beta synthase deficient homocystinuria...
