About Folic Acid Info
Folic Acid Info is an independent, evidence-based reference on folic acid and folate, written in plain language and built on primary sources.
Folic Acid Info answers practical questions about folic acid and folate: how much people need, where to get it, when it matters most, and when to talk to a clinician. We write for everyday readers, people planning a pregnancy, and anyone who has been told to take folic acid alongside a medicine.
Why this site exists
Folic acid is one of the best-proven tools in public health. Taken at the right time, it helps prevent serious birth defects of the brain and spine.12 It is also surrounded by confusing labels, conflicting advice, and supplement marketing. Labels mix mcg of folic acid with mcg DFE, and online claims about MTHFR, methylfolate, and "megadoses" often go beyond the evidence.
Our job is to make the evidence easy to read and easy to check.
How we write
- Primary sources only. We build every page on government health agencies (CDC, NIH, FDA), clinical guidelines (USPSTF, ACOG, NHS, WHO), and peer-reviewed research. Each claim links to its source.
- Evidence is graded. We separate established benefits from possible, mixed, and unsupported claims, and we say so plainly.
- Precise units. We always state whether a number is mcg of folic acid or mcg DFE, and whether it applies to routine prevention or to medical treatment.
- Kept current. Every page shows when it was last updated, and we revise pages when guidance changes.
