How strong is the evidence for Tart Cherry?

A systematic review and meta-analysis found tart cherry (typically Montmorency variety) supplementation modestly aids recovery from strenuous exercise, with a separate meta-analysis finding benefit for endurance exercise performance specifically. That evidence is currently rated moderate (52/100), built on 8 published studies, including 5 randomized controlled trials and 2 meta-analyses -- a reasonable base, but not yet enough for full certainty.
