Royal jelly is the protein-rich secretion worker bees feed to queen larvae. It contains a unique fatty acid, 10-HDA, and is marketed for everything from energy to longevity — claims that outrun the data.
Key takeaways
- Contains proteins, B-vitamins and the signature fatty acid 10-hydroxy-2-decenoic acid (10-HDA).
- Small studies hint at effects on cholesterol, menopausal symptoms and blood sugar — but evidence is preliminary.1
- Not a proven treatment for any condition.
- Allergy risk is real and can be severe (asthma, anaphylaxis) — avoid if you have bee/pollen allergy or asthma.
What it is
A milky glandular secretion of nurse bees, extraordinary in that it turns a genetically ordinary larva into a queen. In humans it’s a functional food supplement, taken fresh, freeze-dried or in capsules.
The evidence
Systematic reviews describe promising but limited human data — modest signals for lipid profile, glucose and menopausal symptoms, with small, variable studies.1 It’s best viewed as a traditional tonic with early science, not a proven remedy.
Safety
The main concern is allergy: royal jelly has caused serious asthma and anaphylactic reactions. Avoid if you have asthma or bee/pollen allergies, and in pregnancy without advice.
How to use
Doses vary widely by product; follow the label. Quality and freshness matter, and pesticide contamination has been reported — choose reputable sources.
