claimHowever, the limited number of independent trials, substantial clinical and methodological indirectness, and low-to-very-low certainty of evidence prevent firm conclusions regarding either benefit or lack of benefit.

claimBackground Polyphenol-rich supplements are widely used to support exercise recovery, but whether these recovery-oriented effects translate into long-term resistance-training adaptations remains unclear.
