Folic acid is converted to tetrahydrofolate (THF) in the liver, which supports methylation, DNA and RNA synthesis, and red blood cell maturation. Essential for homocysteine regulation, fetal development, and neurological function.
Used in pregnancy care, anaemia, cardiovascular risk reduction (via homocysteine control), depression, and cognitive decline protocols
Not traditionally used in herbal systems due to its synthetic origin. Natural folate-rich herbs (e.g. nettle, moringa, spinach) are used traditionally for similar benefits
Commonly administered as capsules, tablets, or within multivitamin or prenatal formulas.
High doses may mask B12 deficiency. Individuals with MTHFR mutations may poorly convert folic acid to active form (L-methylfolate preferred).
May be affected by anticonvulsants, methotrexate, sulfasalazine. Supplementation may alter efficacy of these medications.
