Krill Oil May Support Muscle Strength and Size in Older Adults
This clinical trial looked at whether daily krill oil supplementation could help maintain muscle strength and size in healthy older adults who weren’t doing much structured exercise. Men and women over 65 took either 4 grams of krill oil per day or a placebo for six months.
Researchers measured leg strength (knee extensor torque), grip strength, and the thickness of a key thigh muscle (vastus lateralis) at the start, 6 weeks, and 6 months. They also tracked body composition, blood markers, and other measures of muscle and nerve function.
After six months, the group taking krill oil showed increases in knee extensor strength, grip strength, and muscle thickness compared to the placebo group.
What this means for you
For older adults who aren’t very physically active, this study suggests that krill oil supplementation may be associated with modest improvements in muscle strength and size over six months. This adds to research exploring how omega-3 fatty acids might support healthy aging, though it’s not a substitute for resistance exercise or medical advice about muscle health.
