It has been postulated that co-administration of pharmacologically standardized nutrients nutraceuticals , such as folate, would potentiate the effect of antidepressants. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. We concluded augmentation with folate for the treatment of major depressive disorder probably results in little or no difference in depressive symptoms. It would be interesting to evaluate the effects of specific presentation forms of folate or in population with objective folate deficit. After the introduction of antidepressants in the s, the number of pharmacological treatments for major depressive disorder has increased, but the efficacy of these has remained largely unchanged.
Investigators have been examining the link between folate deficiency and major depression for the past five decades. Folate requires enzymatic conversion to L-methylfolate, which is the biologically active form of folic acid and can be prescribed as a prescription medical food. The enzyme MTHFR, which catalyzes the rate-determining step in L-methylfolate synthesis, is subject to a common polymorphism rendering the enzyme less effective. This can lead to lower levels of L-methylfolate being available to activate tetrohydropbiopterin for serotonin production in the raphe nucleus. Recent data strongly suggest that L-methylfolate is an effective augmentation strategy for major depression at both the initial onset of symptoms and in patients with treatment-resistant depression. Because there is limited evidence-based information available on successful augmentation strategies, physicians often base augmentation decisions on the presence of a particular symptom, avoidance of side effects, or cost. The link between folate deficiency and major depression has been investigated for the past 50 years.
A B vitamin found in leafy green vegetables, citrus fruits, and beans may be useful in the treatment of depression and other psychiatric symptoms. Folate or folic acid, also known as vitamin B 9 , is already known to be important for health. Pregnant women need a certain amount to prevent miscarriage and birth defects, and although there is no proof, some think that it provides protection against heart disease, stroke, and certain cancers. Since , the FDA has required the addition of folate to enriched flour and other grain products. The recommended dose is mcg 0. Older people may also need higher doses because they don't absorb folate well. Along with vitamins B 6 and B 12 , folate helps break down the amino acid homocysteine.
Metrics details. Evidence suggests that folate deficiency may be causatively linked to depressive symptoms. However, little is known on the status of use of folic acid and vitamin supplements among people with mental disorders. This study examined the prevalence and the likelihood of use of folic acid or vitamin supplements among adults with depression and anxiety in comparison to those without these conditions. Use of folic acid and vitamin supplements did not differ significantly by elevated depressive symptoms in either sex.
L-methylfolate, a new option in psychiatric treatment, would it be linked to psoriasis relapse? We report a case of a years-old woman in remission of psoriasis for 20 years. The L-methylfolate was prescribed as an adjuvant for the treatment of depression in a patient with the methylenetetrahydrofolate reductase gene polymorphism MTHFR. Folate, a B vitamin, is essential to the brain for noradrenalin syntheses, serotonin, and dopamine. Three forms of folate are commonly used: folic acid, 5- methyltetrahydrofolate 5-MTHF, methylfolate and L-methylfolate and folic acid.
Recent reports suggest that people with lower folate levels are at higher risk of major depression or may experience more severe depressive symptoms. Other studies indicate that in folate deficient patients, antidepressants may be less effective or may take longer to take effect. In addition, some clinical trials have shown that folate may have a therapeutic effect on depression , either when taken alone or in combination with an antidepressant. This enzyme is essential for the conversion of dietary folate to its active metabolite, MTHF or L-methylfolate. It is believed that people with this variant of MTHFR have lower levels of L-methylfolate available for the synthesis of certain neurotransmitters, including serotonin.
