5-Methyltetrahydrofolic acid disodium salt is widely used in the pharmaceutical and nutraceutical industries as a bioactive form of folate. It is particularly important in dietary supplements aimed at supporting healthy folate levels, especially for individuals with genetic variations like MTHFR mutations that impair folate metabolism. This compound is also utilized in prenatal vitamins to support fetal development and reduce the risk of neural tube defects. Additionally, it plays a role in cardiovascular health by aiding in the regulation of homocysteine levels. Its stability and bioavailability make it a preferred choice in formulations designed to address folate deficiency and related health conditions.
