The Claim

Omega-3 fatty acid supplementation at approximately 2 grams per day for at least six months is associated with increased thigh muscle volume, improved grip strength, and reduced intermuscular fat in older adults, likely through anti-inflammatory effects and enhanced mitochondrial function.

In plain English

In older adults, taking about 2 grams of omega-3 fatty acids daily for six months or longer is linked to larger thigh muscles, stronger grip, and less fat between muscles.

See the scientific wording

Omega-3 fatty acid supplementation at approximately 2 grams per day for at least six months is associated with increased thigh muscle volume, improved grip strength, and reduced intermuscular fat in older adults, likely through anti-inflammatory effects and enhanced mitochondrial function.

Why this might work

Omega-3 fatty acids enter muscle cells and calm down chronic inflammation, which stops the body from breaking down muscle too quickly. They also improve the energy factories inside muscle cells, helping them produce more power and resist damage. This allows muscle fibers to grow larger, keeps fat from building up between muscles, and makes the muscles stronger.

    This study says taking 2 grams of omega-3s daily helps older adults build stronger muscles and get stronger, which matches what the claim says. It doesn’t measure fat inside muscles exactly, but it does show the main benefits the claim talks about.
