Weak folate metabolism is usually indicative of a problem with the genes that control folate metabolism, including the methylenetetrahydrofolate reductase gene, and the methionine synthase reductase gene. If mutations occur in both, they can lead to decreased metabolism of folate. The gene mutation may lead to a decrease in the activity of the enzyme and subsequently lead to a deficiency of folate in the body or an increase in homocysteine levels, which can then induce many diseases, including abnormal development and neural tube diseases due to folate deficiency during pregnancy, and also cause cardiovascular and cerebrovascular diseases in adults, as well as aplastic anemia and hypertension. Therefore, people with weak folic acid metabolism need to change the level of folic acid in their bodies by supplementing with extra folic acid to avoid the above-mentioned conditions caused by weak folic acid metabolism, which can be treated by taking folic acid tablets etc. under the guidance of a doctor. At the same time, you can eat more folic acid-rich foods in your diet, such as spinach, tomatoes, carrots, animal liver, milk, etc.
