Royal jelly

Tier 3 — weak evidence · Immunity · Skin · Energy

A nutrient-rich substance produced by honeybees that contains unique proteins, sugars, and fatty acids. Small trials suggest modest effects on cholesterol and blood sugar, but study quality is generally poor. Allergic reactions are a real concern, especially in people with bee or pollen allergies. Severe reactions including anaphylaxis are possible.

Dose: 300–1,000 mg/day; avoid if allergic to bee products — anaphylaxis risk
