Folic acid can not lower uric acid, moreover, there is no folic acid to lower uric acid mechanism said. Uric acid is the end product of purine metabolism, if the production of uric acid is too much, or the excretion is blocked, it is easy to cause hyperuricemia. Hyperuricemia patients can take under the guidance of the doctor to increase uric acid excretion of drugs such as benzbromarone, or some inhibit the synthesis of uric acid drugs such as allopurinol, febuxostat and other uric acid treatment. Folic acid is a water-soluble vitamin, which can prevent fetal neural tube malformations when taken during pregnancy, but does not have the effect of lowering uric acid. Therefore, if the patient has high uric acid, it is recommended to consult the rheumatology and immunology department in time and standardize the treatment under the guidance of the doctor.
