The Claim

Carnosine supplementation reduces hemoglobin A1C (HbA1C) levels by approximately 0.92% in adults with metabolic disorders, as demonstrated by pooled data from 4 randomized controlled trials involving 184 participants.

Source: Effect of carnosine supplementation on lipid profile, fasting blood glucose, HbA1C and insulin resistance: A systematic review and meta-analysis of long-term randomized controlled trials.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

Taking carnosine supplements may help lower blood sugar levels in adults with conditions like diabetes or prediabetes, with research showing about a 1% drop in a key blood sugar marker.

What the research says

1 study

  1. Study: Effect of carnosine supplementation on lipid profile, fasting blood glucose, HbA1C and insulin resistance: A systematic review and meta-analysis of long-term randomized controlled trials.

    This study directly tests carnosine supplements and found they reduce HbA1C by exactly 0.92% - the same amount claimed. The study used 4 trials with 184 people, matching the claim perfectly.
