What is Royal Jelly?

Royal Jelly (Apis mellifera secretion) is a longevity supplement used for possible menopausal-symptom relief. NutriDex grades the human evidence as Preliminary. Royal jelly is the secretion worker bees feed to queen larvae, sold as a vitality and anti-aging tonic. Small randomized trials report reduced menopausal symptoms and modest improvements in cholesterol, and lab work shows antioxidant activity. The human evidence base is small and preliminary, however, and the more sweeping anti-aging claims are unproven. Its most important caveat is allergy risk.

Purported Benefits

✓Possible menopausal-symptom relief
✓Possible modest cholesterol improvement
✓(Claimed) general 'vitality' tonic

Evidence by outcome

The same supplement can be well-proven for one use and unproven for another — here is the human evidence graded outcome by outcome.

OutcomeEvidenceEffectStudies
Menopausal symptom reliefMeta-analysis of 6 RCTs (n=471) found a significant benefit (SMD 0.73, I2=0%), rated moderate-quality evidence. Moderate ↑ benefit · moderate 2
Lipid profile / cholesterolGRADE overviews report modest lipid improvements, but effects are small and pooled with other bee products. Preliminary ↑ benefit · small 2
Antioxidant status (MDA, TAC)Meta-analysis of 6 RCTs lowered MDA and raised total antioxidant capacity, but did not change hs-CRP. Moderate ↑ benefit · moderate 1

Body weight / BMI / fat massGRADE dose-response meta-analysis of 10 RCTs found no significant effect on weight, BMI or fat mass. Moderate — no effect · negligible 1

Dosing & Compounds

Typical Dose
Commonly 300–1,000 mg/day in studies.

Key Studies ★ 15 studies

meta-analysis Menopause meta-analysis (2026) ✓ PubMed
Meta-analysis of 6 RCTs (n=471 postmenopausal women) found royal jelly significantly improved postmenopausal symptoms vs placebo (SMD 0.73, 95% CI 0.50-0.96, I2=0%, moderate-quality evidence).
meta-analysis Liver enzymes & glycemic meta-analysis (2023) ✓ PubMed
Meta-analysis of 10 RCTs found no significant overall effect on liver enzymes or glycemic indices, but a subgroup of trials >=8 weeks showed reduced fasting glucose (WMD -4.28 mg/dl, 95% CI -7.41 to -1.14).
meta-analysis Inflammation & oxidative stress meta-analysis (2025) ✓ Full text
Meta-analysis of 6 RCTs (7 datasets) found royal jelly significantly reduced malondialdehyde and increased total antioxidant capacity, but did not significantly change hs-CRP.
systematic review (overview) Cardiometabolic overview of systematic reviews (2025) ✓ Source
GRADE-assessed overview of systematic reviews reported honey/royal jelly derivatives improved blood pressure, lipid profiles, glycemic indices, and total antioxidant capacity, with effects generally modest.
meta-analysis Anthropometric indices meta-analysis (2023) ✓ Source
GRADE-assessed dose-response meta-analysis of 10 RCTs (n=512) found no significant overall effect on body weight, BMI, or fat mass, though a subgroup at doses <3,000 mg/day showed modest reductions in body weight and BMI.
Systematic review Vajdi 2023 ✓ Full text
GRADE-assessed dose-response meta-analysis of 10 RCTs (512 participants) found no significant effect of royal jelly on body weight (WMD -0.29 kg, 95% CI -1.24 to 0.65), BMI (WMD 0.11, 95% CI -0.29 to 0.52), or fat mass; evidence low-to-moderate.
Systematic review Norouzzadeh (umbrella review/GRADE) 2025 ✓ PubMed
Umbrella review and GRADE-assessed updated meta-analysis of honey-bee products (69 RCTs, 3544 participants). Royal jelly showed dose-dependent improvements in blood pressure, lipid profiles, glycemic indices, and total antioxidant capacity, with adequate certainty of evidence; contrasted with honey, which adversely affected SBP, triglycerides, FBG and hs-CRP.
Meta-analysis Taheri 2025 (inflammation/oxidative stress) ✓ PubMed
Meta-analysis of 7 datasets from 6 RCTs. Royal jelly significantly reduced malondialdehyde (WMD -1.79; 95% CI -3.00 to -0.58; p=0.004) and increased total antioxidant capacity (WMD 0.98; 95% CI 0.24 to 1.71; p=0.009), but did not significantly change hs-CRP (WMD -0.24; 95% CI -0.60 to 0.10; p=0.17).
Meta-analysis Vajdi 2023 (anthropometric indices) ✓ PubMed
GRADE-assessed dose-response meta-analysis of 10 RCTs (512 participants). No significant overall effect on body weight (WMD -0.29 kg), BMI (WMD 0.11 kg/m2), or fat mass; however a significant reduction in body weight and BMI occurred in the subgroup using royal jelly doses <3000 mg/day.
systematic review Glycemic regulation systematic review (2019) ✓ PubMed
Systematic review of 5 RCTs (n=205, doses 500-6,000 mg/day for 4-8 weeks) found royal jelly did not significantly reduce fasting plasma glucose or HbA1c overall, indicating inconsistent glycemic benefit.
RCT Vascular endothelial function RCT (2022) ✓ PubMed
Randomized double-blind placebo-controlled trial in 100 healthy volunteers found royal jelly 690 mg/day for 4 weeks significantly improved endothelial function (RH-PAT index relative change 21.4% vs 0.05% placebo, P=0.037) and lowered ALT and GGT.
case report Anaphylaxis from major royal jelly protein 3 (2022) ✓ PubMed
Case report documented IgE-mediated anaphylaxis after royal jelly ingestion driven by major royal jelly protein 3, with cross-reactivity to honeycomb, underscoring serious allergy risk in atopic individuals.
Study Menopause RCTs ✓ PubMed
Some trials report reduced menopausal symptoms (e.g. ~1,000 mg/day).
