Summary

This completed study tested whether taking krill oil supplements for six months could improve muscle strength and mass in adults aged 35 to 60. Fifty-four participants took either krill oil or a vegetable oil placebo. The researchers measured changes in leg strength, grip strength, and body composition to see if the supplement helps fight age-related muscle loss.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: krill oil
What this could lead to: If it works, this could point toward a simple supplement to help maintain muscle strength and mass in middle-aged adults, potentially reducing the risk of sarcopenia.
What could go wrong: This is a small, completed trial with only 54 participants. The results may not apply to everyone, and supplements like krill oil often show modest effects that don't translate into real-world benefits.
