5-MTHF Supplement Information and Usage Guide

5-MTHF is the active form of folate, essential for methylation, DNA synthesis, and homocysteine regulation.

5-MTHF (5-methyltetrahydrofolate) is the biologically active form of folate, also known as vitamin B9. Unlike synthetic folic acid, 5-MTHF can be used directly by the body without the need for enzymatic conversion.

This form is especially important for individuals with genetic variants such as MTHFR mutations, which impair the ability to convert folic acid into its active form. Supplementing with 5-MTHF ensures efficient folate metabolism and proper methylation support.

5-MTHF plays a key role in DNA synthesis, neurotransmitter production, and the regulation of homocysteine, making it essential for cardiovascular, cognitive, and reproductive health.

Other names & forms of 5-MTHF supplement : 5-MTHF, L-5-MTHF, L-methylfolate, methylfolate, levomefolic acid, 5-methyltetrahydrofolate, active folate

Benefits

As the active form of folate, 5-MTHF bypasses the conversion step required by folic acid and directly participates in critical methylation processes. This makes it especially valuable for individuals with MTHFR gene variants and those needing bioavailable folate.

• Supports cardiovascular health by helping regulate homocysteine levels.
• Contributes to cognitive function and mood balance through neurotransmitter synthesis.
• Essential for prenatal health and reducing the risk of neural tube defects.
• May improve outcomes in individuals with folate metabolism disorders, including MTHFR mutations.
• Assists in detoxification processes via methylation pathways.

Dosage

Health professionals suggest that the dosage of 5-MTHF supplement be customized for each individual:

Typical dosages range from 400 mcg to 1 mg per day, depending on individual needs and medical advice. Therapeutic use for MTHFR mutations or pregnancy may involve higher doses under professional supervision.

Side Effects

5-MTHF is generally well-tolerated when taken at appropriate doses. In rare cases, some individuals may experience nausea, irritability, or sleep disturbances. Very high doses could potentially lead to overmethylation-related symptoms such as anxiety or agitation.

Interactions

5-MTHF may interact with certain medications such as anticonvulsants, methotrexate, and antidepressants. It can also affect the metabolism of other B-vitamins like B6 and B12, especially when used in methylation protocols. Combining with other supplements like Vitamin B12 and Vitamin B6 is often recommended to balance effects.

Precautions

Individuals with bipolar disorder or who are on medications affecting mood should use 5-MTHF cautiously, as it may influence neurotransmitter activity. It's advisable to consult a healthcare provider before beginning supplementation, especially for those with MTHFR mutations or other methylation disorders.
