Rating (out of 5): 5

Vitamin B9, also known as folate, and in supplemental form as methylfolate or folic acid, has strong scientific backing for its use in supporting and treating certain types of anemia, specifically megaloblastic anemia. This condition arises when red blood cells are abnormally large and immature due to impaired DNA synthesis, most commonly resulting from deficiencies in vitamin B12 or folate. Folate is essential for DNA synthesis and repair, and its deficiency impairs the maturation of red blood cells, leading to anemia.

Multiple clinical studies and authoritative medical guidelines (such as those from the World Health Organization and the American Society of Hematology) recommend folic acid supplementation as the standard treatment for folate-deficiency anemia. Methylfolate is an active, bioavailable form of folate, particularly important in individuals with certain genetic polymorphisms (such as MTHFR mutations) that reduce their ability to convert folic acid into its active form.

Supplementation with folate corrects the underlying deficiency, restores normal red blood cell production, and resolves the anemia. However, it is important to differentiate folate deficiency anemia from B12 deficiency anemia, as treating the latter with folate alone can mask neurological symptoms without addressing the underlying cause.

In summary, the use of vitamin B9 (methylfolate) in the treatment and prevention of folate-deficiency anemia is well-established and scientifically validated.
