Surprising

Fish oil helped vertical jump recover to baseline after muscle damage in a 72-hour trial — but only the placebo group's performance actually fell.

This small, short-term trial suggests a possible recovery benefit from acute fish oil, but it's the first of its kind and the effect was modest — don't expect a jump in your jump without more evidence.

In a double-blind RCT, healthy adults who took fish oil after exercise-induced muscle damage regained their vertical jump height within 48 hours, while the placebo group still lagged. The same study also found less soreness and better strength recovery on some measures, but fish oil did not lower a key inflammation marker (TNF-α), hinting the mechanism isn't a simple anti-inflammatory one.

Where this fits in the evidence

This is among the first studies we've indexed on Fish Oil for Improved Vertical Jump Performance — treat it as an early signal until more research accumulates.
