The Claim

Omega-3 fatty acid supplementation, particularly with EPA and DHA, is associated with increased incorporation of these fatty acids into skeletal muscle and mitochondrial membranes, which may support muscle protein synthesis and mitochondrial function, though human trials show inconsistent effects on muscle protein synthesis rates in healthy adults.

Roughly balanced

Support and challenge are close. The picture may shift as more studies come in.

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 omega-3 supplements like EPA and DHA might help these fats get into your muscle and energy-producing parts of cells, which could help your muscles grow and work better—but studies in healthy people don’t always agree on whether it actually boosts muscle building.

What the research says

1 study
  1. Study: Skeletal muscle protein turnover and mitochondrial responses to omega-3 fatty acid supplementation: an update

    Taking omega-3 supplements might help your muscles and energy factories (mitochondria) work better, but not everyone sees a difference in muscle growth — it depends on the person and how the study was done.
