From the Guidelines
When you have MTHFR deficiency, it's essential to be careful with certain medications, supplements, and lifestyle factors.
Key Precautions
- Be cautious with medications like methotrexate, phenytoin, and warfarin, as they may interact with the MTHFR gene mutation 1.
- Avoid high doses of folic acid, as it can mask vitamin B12 deficiency, and instead, opt for methylfolate or folinic acid supplements 1.
- Limit exposure to environmental toxins, such as heavy metals and pesticides, and maintain a healthy diet rich in fruits, vegetables, and whole grains.
- It's also crucial to work closely with your healthcare provider to monitor homocysteine levels and adjust your treatment plan accordingly 1.
Dietary Considerations
- Consider avoiding or being cautious with certain foods, such as those high in synthetic folic acid, and opt for natural sources of folate instead, such as pulses, leafy green vegetables, egg, nuts, and whole grain products 1.
- Ensure adequate intake of vitamin B12, as it plays a crucial role in homocysteine metabolism, and consider supplementation if necessary 1.
Additional Considerations
- Riboflavin supplementation may be beneficial in reducing homocysteine levels, particularly in individuals with the MTHFR 677 TT genotype 1.
- Regular monitoring of homocysteine levels and adjustment of treatment plans can help mitigate the risks associated with MTHFR deficiency 1.
From the Research
Precautions for Individuals with MTHFR Deficiency
Individuals with Methylenetetrahydrofolate Reductase (MTHFR) deficiency should take the following precautions:
- Be aware of the increased risk of cardiovascular disease, dementia, and depression due to moderate hyperhomocysteinemia-induced low folate status 2
- Monitor serum folate and total homocysteine (tHcy) levels, as MTHFR C677T polymorphisms can influence these levels 2, 3
- Consider genetic testing for MTHFR polymorphisms, especially for individuals with a family history of cardiovascular disease or other related conditions 3, 4
- Maintain a healthy lifestyle, including a balanced diet rich in folate, vitamin B12, and vitamin B6, to help manage homocysteine levels 2, 5
- Avoid the use of anabolic androgenic steroids (AAS), as they can raise homocysteine levels and increase the risk of ischemic stroke and other cardiovascular events 4
- Consider supplementation with folate, vitamin B6, and vitamin B12, especially for individuals with migraine or diabetes mellitus, as these conditions have been linked to MTHFR gene polymorphisms 5, 6
Specific Considerations for Related Conditions
- For individuals with migraine, particularly those with aura, determination of MTHFR C677T polymorphisms and measurement of homocysteine concentrations may be useful for disease prevention 5
- For individuals with diabetes mellitus, MTHFR gene polymorphisms may play a significant role in the pathophysiology of the disease, including inflammation and insulin resistance 6
- For individuals with a history of ischemic stroke or cardiovascular disease, screening for MTHFR polymorphisms and aggressive risk reduction with lifestyle modifications and medical therapy may be necessary for secondary prevention 3, 4
