The Claim

In healthy older adults, the combination of fish oil supplementation and resistance training results in greater increases in fatty acid oxidation compared to resistance training alone, demonstrating a synergistic metabolic effect not produced by either intervention individually.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

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

How it works
1 study reviewed
In plain English

In healthy older adults, taking fish oil supplements while doing resistance training leads to higher rates of fatty acid oxidation than resistance training by itself, and this combined effect is not seen with either intervention alone.

See the scientific wording

The combination of fish oil supplementation and resistance training in healthy older adults leads to greater increases in fatty acid oxidation than resistance training alone, indicating a synergistic metabolic effect that is not achieved by either intervention alone.

Why this might work

Fish oil increases the amount of omega-3 fats in muscle cell membranes, which allows more fatty acids to enter the mitochondria. Resistance training activates the machinery inside mitochondria that burns these fats for energy. Together, they make the muscle burn more fat than either one alone.

  1. Study: Fish oil administration combined with resistance exercise training improves strength, resting metabolic rate, and inflammation in older adults

    When older adults did strength training plus took fish oil, their bodies got better at burning fat — but those who only did strength training didn’t see this benefit. So fish oil made a difference when paired with lifting weights.
