Hi! Honestly, best approach is to check with your OB about what dosage and brand works best for your specific needs, since they'll know your health history, marami namang reliable options out there, pero personalized recommendation talaga ang best para sa TTC journey mo. You're already thinking ahead by starting folic acid, and that's such a smart move! Your doctor can guide you on timing and dosage din to maximize your chances. You've got this, mama!
