Royal jelly
The verdict
No credible fertility evidence found for this item; separately, it carries a real, well-documented anaphylaxis risk in anyone with bee-product sensitivity — a distinct safety mechanism from the liver/pregnancy risks flagged elsewhere in this dataset.
A bee-derived substance, marketed as a general fertility and vitality supplement.
What the evidence shows
This pass found no meaningful fertility evidence — the closest relevant trial (royal jelly for menopausal genitourinary syndrome) found no benefit even for its own tested use case.
Evidence tier
Documented harm⛔ Peer-reviewed evidence of serious adverse effects from the item's own chemistry/pharmacology or a well-characterized allergic mechanism. More serious than contamination; not resolved by buying a 'reputable brand'.
