Can prenatal multivitamins with folic acid become less effective over time?

It is important to note that prenatal multivitamins with folic acid do not become less effective over time. It is recommended to take the prescribed dose as directed by a healthcare professional, as doubling the dose will not increase fertility. It may take up to 12 months to conceive, even for healthy individuals, so it is important to be patient and consistent with your prenatal vitamin regimen. If you have any further questions or concerns, it is best to consult with a healthcare provider for personalized advice.
