The Role of Folic Acid in Cancer Treatment Courses
Folic Acid (also known as Vitamin B9) is an indispensable nutrient in cancer treatment courses. It plays a core role in red blood cell production, DNA synthesis, and cell repair. During chemotherapy or radiotherapy, folic acid consumption is extremely high, and deficiency directly exacerbates anaemia, fatigue, and oral mucosal damage.
Many patients develop severe folic acid insufficiency due to treatment-induced intestinal absorption impairment, loss of appetite, and vomiting, which reduces treatment tolerance.
Folic acid is not an “anti-cancer vitamin” but serves as supportive care, helping patients maintain stable blood counts, energy supply, and mucosal repair under high-intensity treatment, allowing them to proceed more steadily and smoothly.
