How many studies support Muscle Recovery?

Beyond protein and creatine (covered elsewhere), several other nutritional interventions have meta-analytic support for easing exercise-induced muscle damage: dietary flavonoid-containing polyphenols and nitrate-rich beetroot juice both show modest benefit for muscle-damage markers in meta-analysis, as does curcumin supplementation for delayed-onset muscle soreness. That's backed by 6 published studies in Vitaebase's database, including 6 meta-analyses, the most recent from 2022 -- a modest but real research base.
