The Claim

Fish oil supplementation combined with resistance training reduces systemic inflammation, as measured by interleukin-6 and C-reactive protein, in healthy older adults, compared to resistance training alone.

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.

Cause and effect
1 study reviewed
In plain English

In healthy older adults, taking fish oil along with resistance training lowers levels of interleukin-6 and C-reactive protein in the blood, while resistance training without fish oil does not lower these markers.

See the scientific wording

Fish oil supplementation combined with resistance training reduces systemic inflammation, as measured by interleukin-6 and C-reactive protein, in healthy older adults, whereas resistance training alone does not produce this effect.

Why this might work

Fish oil provides fatty acids that enter immune cells and block a key signaling switch that turns on inflammation. When muscles are worked, they release signals that normally increase inflammation, but these fatty acids stop that switch from activating. This prevents the body from making too much of the inflammatory chemicals that show up in the blood.

  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 and took fish oil, their blood inflammation levels went down — but when they only did strength training, their inflammation didn’t change. So fish oil helped reduce inflammation when combined with lifting weights.
