NO
This study assesses whether royal jelly improves endothelial function.
Efficacy
Improvement of vascular endothelial function assessed by the change of rective hyperemia peripheral arterial tonometry (RH-PAT) index 4 weeks after administration of royal jelly supplements.
Secondary endpoints are the change of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and gamma-glutamyl transpeptidase (gammaGT) for liver function and high-density lipoprotein-cholesterol (HDL-C), low-density lipoprotein-cholesterol (LDL-C), and triglycerides.

Administration of capsuled royal jelly 690 mg daily (equivalent 2040 mg of fresh royal jelly) for 4 weeks.
Administration of placebo supplement for 4 weeks.

The percentage relative change in the RH-PAT index was significantly higher in the royal jelly group than in the placebo group (21.4%plusminus53.1% vs. 0.05%plusminus40.9%, P=0.037).

The mean age of the participants was 35.0plusminus9.3 years in the placebo group and 36.1plusminus9.1 years in the royal jelly groups; 45% and 50% of the placebo and the royal jelly groups, respectively, were male.
After acquisition of written informed consent, an independent investigator performed the randomization. Participants were randomly assigned to receive royal jelly 690 mg (equivalent 2040 mg of fresh royal jelly) or placebo daily for 4 weeks. Vascular endothelial function assessed on the basis of RH-PAT and blood chemistry were compared between baseline and 4 weeks after enrollment.
