What is the MTHFR Gene?
The MTHFR gene, or methylenetetrahydrofolate reductase gene, provides the blueprint for producing the methylenetetrahydrofolate reductase mthfr protein, a crucial enzyme in folate metabolism. This protein helps convert folate into its active form, enabling the body to utilize this essential vitamin effectively. Without proper MTHFR function, the body would struggle to process folate, leading to potential health issues. Individuals with MTHFR polymorphism may experience challenges in processing folic acid, necessitating the use of active forms of folate, such as 5-MTHF, in supplementation.
Each of us carries two copies of the MTHFR gene, inherited from our parents. Folate, a form of vitamin B9, is vital for making DNA and modifying proteins, which are crucial for overall cellular function. It also plays a significant role in breaking down homocysteine, an amino acid that can be harmful at elevated levels. Thus, the MTHFR gene is integral to maintaining cellular health and preventing toxic buildup in the body.
Recognizing the MTHFR gene’s role is crucial in understanding its impact on health. Ensuring optimal folate metabolism supports DNA synthesis, protein modification, and breakdown of harmful compounds like homocysteine.

MTHFR polymorphism can lead to inefficient folate processing, making it crucial for individuals with this genetic variation to use active forms of folate, such as 5-MTHF, to address potential deficiencies.
When the MTHFR enzyme malfunctions due to genetic mutations, it hinders the body’s ability to convert folate into its active form, 5-methyltetrahydrofolate, which is necessary for metabolizing homocysteine. This inefficiency can result in high homocysteine levels in the bloodstream, posing various health risks. To counteract these effects, individuals with MTHFR variants often need increased folate intake through diet and supplements.
Methylfolate, an active form of folate, is especially beneficial for individuals with MTHFR mutations due to its higher bioavailability. It aids in lowering homocysteine levels and supports DNA production and cellular function. Awareness of how MTHFR mutations affect folate metabolism is important for managing health risks and optimizing nutrient intake.
Importance of Folic Acid Supplementation
For women of childbearing age, folic acid supplementation is vital due to the link between high homocysteine levels during pregnancy and increased risk of neural tube defects in infants. A daily intake of 400 mcg of folic acid is recommended by healthcare providers to ensure sufficient folate levels for healthy fetal development, irrespective of MTHFR status.
While taking more than 400 mcg of folic acid daily does not necessarily offer additional protection against neural tube defects, it is essential to maintain adequate levels to prevent deficiencies. Folic acid fortification at recommended levels has not been shown to cause adverse effects, making it a safe and effective strategy for ensuring proper folate metabolism.
For individuals with MTHFR gene mutations, supplementing with methylfolate can be particularly beneficial. This form of folate is more readily utilized by the body, helping to lower the risk of complications associated with MTHFR mutations. Adequate intake of vitamins B12, B6, and folate is essential for managing homocysteine levels and supporting overall health.
Active Folate vs. Folic Acid
Methylfolate (5-MTHF) is often recommended for individuals with MTHFR gene variants because of its superior bioavailability. Unlike synthetic folic acid, which requires conversion in the body, methylfolate is already active, making it easier for those with MTHFR mutations to utilize. This form ensures efficient folate metabolism and supports cellular function. For individuals with MTHFR polymorphism, using active forms of folate like methylfolate is essential to ensure efficient folate metabolism and reduce health risks.
While individuals with MTHFR mutations can process all types of folate, they may not convert synthetic folic acid efficiently.
