Quick Answer
Folic Acid Pregnancy Guideline has evidence relevant to safety, limits, and clinician-discussion contexts, but conclusions should stay close to the cited sources.

Key Takeaways
- 015 6 7 8 9 However, a significant gap exists globally between folic acid supplementation practices and scientific evidence. [Li Jiahe (2026)]
- 02A study in China found that only 16.1% of pregnant women took folic acid at the correct time []. [Li Jiahe (2026)]
- 03A systematic review of global data (2000–2014) found that folate deficiency (serum folate < 10 nmol/L) affected >20% of women of reproductive age in many lower-income countries, while folate insufficiency (red blood cell folate < 906 nmol/L for NTD risk reduction) exceeded 40% in most countries surveyed []. [Li Jiahe (2026)]

Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording.
