Systematic Review With Meta-Analysis

2020 Jan

This study looked at whether carnosine supplements help lower blood sugar in people with metabolic problems. After combining results from multiple studies, researchers found carnosine did NOT significantly reduce fasting blood sugar - exactly matching what the claim says.
