The Claim

Carnosine supplementation does not produce a statistically significant reduction in circulating triglyceride levels among adults with metabolic disorders, as evidenced by a pooled mean difference of -14.46 mg/dL with a 95% confidence interval spanning from -29.11 to 0.19 mg/dL, which includes zero.

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

Quantitative
1 study reviewed
In plain English

Taking carnosine supplements doesn't seem to lower triglyceride levels in adults with metabolic conditions like diabetes or prediabetes - the research shows a tiny drop that could easily be just random chance.

See the scientific wording

Carnosine supplementation does not significantly reduce triglycerides in adults with metabolic disorders, with a pooled effect of -14.46 mg/dL that crosses zero (95% CI: -29.11 to 0.19)

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 confirms the claim - it tested carnosine supplements on people with metabolic problems and found that triglycerides didn't change in a meaningful way. The small drop they saw (-14.46 mg/dL) could easily be due to chance since the range of possible results included zero.
