Omega-3 Supplements and Blood Fat/Sugar Levels in Type 1 Diabetes: A Meta-Analysis
This meta-analysis pooled results from 18 studies examining whether omega-3 fatty acid supplements affect blood lipid and blood sugar markers in people with type 1 diabetes (T1D).
Combining randomized controlled trials, the researchers found that omega-3 supplementation slightly raised HDL (“good”) cholesterol and modestly lowered triglyceride levels compared to control groups. However, these effects were small and the statistical certainty behind them was described as fragile.
No meaningful differences were found for total cholesterol, LDL cholesterol, fasting blood glucose, or HbA1c (a marker of long-term blood sugar control). Results from studies that only tracked changes before and after supplementation (without a comparison group) were similar to the randomized trial findings.
What this means for you
For people with type 1 diabetes, omega-3 supplementation may offer small improvements in some cholesterol markers, but the evidence is not strong and there was no observed effect on blood sugar control. The researchers suggest larger, better-standardized studies focused on actual cardiovascular outcomes are needed before drawing firm conclusions.
