Methodology
Systematic review and random-effects meta-analysis of ten randomized controlled trials of royal jelly supplementation on plasma liver enzymes and glycemic indices, with subgroup analysis by intervention duration
Key Findings
Neither liver enzymes nor glycemic indices changed significantly overall; only a subgroup of trials lasting eight weeks or more showed reduced fasting plasma glucose.
Conclusions
Overall effects are null, with a weak duration-dependent signal that needs confirmation.
Limitations
Subgroup findings are exploratory; heterogeneity across formulations and populations.
Supplements Studied
Combined estimate of effect sizes for the impact of RJ on neither the plasma liver enzymes nor the glycemic indices were statistically significant.
Outcomes Measured
Royal jelly (RJ) may contribute to glycemic control and liver function through various mechanisms.
