The Claim

Carnosine supplementation has no significant effect on insulin resistance as measured by HOMA-IR in adults with metabolic disorders

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.

Challenges

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

Cause and effect
1 study reviewed
In plain English

Taking carnosine supplements doesn't really change how the body handles insulin in adults who have metabolic problems like diabetes or pre-diabetes.

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 tested whether carnosine supplements help with insulin resistance in people with metabolic problems. It found that carnosine did NOT significantly change insulin resistance (measured by HOMA-IR), which is exactly what the claim says.
