Folinic Acid (5-formyl THF), is an active and reduced form of folate. In the body, folinic acid may be converted into any of the other active forms of folate. Supplying the body with folinic acid bypasses many of the required metabolic steps, and it is rapidly converted to 5MTHF.

Folinic acid, also known as leucovorin, is a biologically active form of folic acid (vitamin B9) that plays a crucial role in various metabolic processes within the human body. Unlike folic acid, folinic acid does not require enzymatic conversion to become biologically active, making it especially valuable in situations where individuals have impaired folic acid metabolism, such as certain medical conditions or medication use. Folinic acid is frequently used as a medication or dietary supplement to address folate deficiencies, particularly in cases of methotrexate therapy for cancer treatment, where it helps mitigate side effects and maintain healthy cell function. Additionally, it is used in the management of megaloblastic anemia, certain neurological disorders, and during pregnancy to support fetal development. Folinic acid's ability to bypass some of the enzymatic steps required for folate activation makes it a versatile and essential component in various medical treatments and nutritional interventions.
