Broccoli-derived supplement did not show faster recovery after muscle-damaging exercise
A small crossover trial found no statistically detectable recovery benefit from a glucoraphanin-rich broccoli powder under the preparation and exercise conditions tested.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
The broccoli-derived supplement showed no statistically detectable recovery advantage over placebo after the exercise challenge. Strength, soreness and other measures changed over time, but the changes did not differ significantly by supplement. This abstract-based result applies to the tested preparation and protocol; a nonsignificant result does not rule out every possible effect.
This small trial tested a short supplementation period, a specific arm-exercise challenge and powder reconstituted with hot water. The abstract does not provide effect estimates or confidence intervals to show which benefits remain plausible.
What researchers found
Time-by-supplement interaction for recovery outcomes
Broccoli powder versus placebo across assessments through 96 hours after exercise; no measured outcome showed a statistically significant difference in its recovery pattern.
What the exercise test measured
Participants performed an elbow-flexor exercise designed to produce muscle damage. Researchers then tracked strength, soreness, blood markers, movement range, arm size and ultrasound measurements, allowing them to examine several aspects of recovery.
Time changes did not show treatment benefit
Several outcomes changed after exercise, confirming that the challenge affected the muscles. The key comparison was whether those changes differed between supplement and placebo. The analysis did not detect such a difference.
