Narrative Review

Human

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

Narrative Review

Human

2026 Mar 1

This study says omega-3s might help muscles in some ways, but it doesn't prove they make you stronger or build muscle on their own — especially without exercise. The results are mixed and not clear enough to support the claim.

Gold Standard Evidence Needed

According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.

Similar Assertions

Taking omega-3 supplements might help your muscles grow better when you eat protein or work out, especially if you're sick or have a medical condition—but it doesn't always work for healthy people.

Taking omega-3 fatty acids might help reduce harmful stress in muscle cells, especially as we age or if we're sick, and this could help muscles stay stronger and work better — but this has only been seen in animal or lab studies so far.

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.

Taking omega-3 fatty acids might help your muscle cells work better and stay healthier as you age or if you're inactive, but it doesn't reliably make your muscles grow or repair faster.
