Introduction
For preconception preparation, folic acid from the brand “Sli’an” is generally recommended in clinical practice. Each Sli’an folic acid tablet contains 400 micrograms. According to the *Dietary Guidelines for Chinese Residents*, women of childbearing age should begin supplementing with 400 micrograms of folic acid daily three months prior to conception and continue supplementation for the first three months of pregnancy. This is because folate levels in a woman’s body do not increase significantly shortly after initiating supplementation.
Pregnant women, of course, require substantial nutritional support for optimal health, as pregnancy is an exceptionally demanding physiological process. Key nutrients typically needed during pregnancy include essential fatty acids, protein, vitamins, and both trace and macronutrients. So, what is the best source of folic acid for women preparing for pregnancy?
Which Folic Acid Supplement Is Best When Preparing for Pregnancy?
Clinically, Sli’an folic acid tablets are commonly recommended for women planning pregnancy. Each tablet contains 400 micrograms (mcg) of folic acid. According to the Chinese Dietary Guidelines, women of childbearing age should begin daily supplementation with 400 mcg of folic acid three months prior to conception and continue this regimen through the first three months of pregnancy. This is because folic acid levels in the body do not rise significantly immediately after initiating supplementation. Moreover, since folic acid may irritate the gastric mucosa—potentially causing gastrointestinal discomfort and reduced appetite—it is advisable to take folic acid tablets approximately 30 minutes after a meal.
Additionally, certain vegetables—particularly green leafy vegetables and fruits—are naturally rich in folate. Therefore, incorporating these foods regularly into one’s diet is highly beneficial.
Folic acid plays critical roles in numerous biological processes, including red blood cell formation and protein synthesis. For pregnant women, adequate folic acid intake helps prevent anemia and preterm birth; most importantly, it significantly reduces the risk of fetal neural tube defects (NTDs), such as spina bifida, encephalocele, and anencephaly. Generally, it takes about three months of daily 0.4 mg folic acid supplementation for tissue folate concentrations to reach an effective protective level. Thus, women should begin supplementation at least three months before conception and continue throughout pregnancy until delivery. During the preconception period and early pregnancy (first trimester), the recommended daily intake is 0.4 mg; during mid- to late pregnancy (second and third trimesters), the recommended daily intake increases to 0.8 mg.
