Can Folsäure help with Fruchtbarkeit?

Folic acid (vitamin B9) is often linked to fertility, especially in women planning pregnancy. The evidence is nuanced: for preventing neural tube defects in the embryo, adequate folic acid intake before and during early pregnancy is strongly supported (human-strong). However, its effect on fertility itself – i.e., the likelihood of conception – is less clear. Some studies show modest benefits in women with certain cycle disorders or MTHFR variants that impair conversion of folic acid to active folate. In men, folic acid may improve sperm quality, but again the evidence is moderate. Important: MyBody-X DNA tests can detect MTHFR variants, but such a finding does not automatically indicate deficiency or a need for supplementation. Folic acid intake should be discussed with a physician, especially if taking medications (e.g., antidepressants, methotrexate). Doses above 400–800 µg/day are not recommended without medical supervision. Overall, folic acid is a key factor for a healthy pregnancy, but not a magic bullet for fertility.
