Folic acid
The verdict
Standard preconception care — take it, but it isn't a "fertility booster."
A B-vitamin; the standard preconception/pregnancy supplement worldwide.
What the evidence shows
Universally recommended for neural-tube-defect prevention — not marketed as, or evidenced as, a fertility booster.
NICE's fertility guideline (NG257) defers to its maternal/child nutrition guideline for dosing rather than treating it as an add-on decision.
Evidence tier
Standard care🟢 Recommended regardless of any fertility-boosting claim — a baseline, not a supplement bet.
