Buying advice

When choosing a vitamin B9 supplement, identify whether you need folic acid (synthetic) or folate (natural). For general use, folic acid is sufficient and cheaper. If you have MTHFR gene mutations, absorption issues, or prefer bioactive forms, opt for methylfolate (e.g., 5-MTHF). Consider dosage (typically 400-800 mcg for adults), quality certifications (USP, NSF), and your dietary restrictions (vegan, gluten-free). Always consult a healthcare provider before starting new supplements, especially during pregnancy.
