Older restriction lists are out of date • Low fat dairy, water, coffee and cherries are associated with lower risk • Losing

KEY TAKEAWAYS • Start at least one month before trying to conceive. The neural tube closes in the first 28 days of pregnancy, often before a pregnancy is known • Folic acid and iron are the two non negotiable ingredients. A product missing either is not doing the core job • Iodine is often missing from prenatal products, and deficiency affects fetal brain development • Avoid high dose vitamin A as retinol.
