Royal jelly's clearest human benefit is easing menopausal symptoms, with reasonable support for lowering oxidative stress. Effects on blood sugar and cholesterol are small and inconsistent, and muscle, skin, mood, and fertility claims rest on single small studies. Longevity has never been tested in people. Its serious risk is severe, sometimes fatal allergic reactions and asthma attacks. (Full Review)
| Marker | Target | Why |
|---|---|---|
| Fasting blood glucose | 75–85 mg/dL | Tracks any metabolic effect and hypoglycemia risk with diabetes drugs |
| HbA1c | <5.4% | Reflects average blood sugar over ~3 months |
| LDL cholesterol | <100 mg/dL | Detects possible lipid changes |
| Triglycerides | <90 mg/dL | Sensitive to metabolic shifts |
| hs-CRP | <1.0 mg/L | Gauges the anti-inflammatory effect |
| Blood pressure | <120/80 mmHg | Detects additive lowering with blood-pressure drugs |
| Liver enzymes (ALT/AST) | ALT ~<25 U/L | Screens general safety |
| Serum IgE / allergy history | Not a numeric range | Flags allergy risk before starting |
Cadence: Baseline, then recheck metabolic and inflammatory markers at 8–12 weeks, then every 6–12 months if continued; check blood pressure or blood sugar more often in the first 4–8 weeks if on blood-pressure or diabetes medication.
