Search and filter this category ↗Laboratory activity does not guarantee performance gains
Quercetin is a flavonoid found in foods such as onions, apples and tea. Concentrated supplements have been researched for several purposes, including exercise performance. Its activity in laboratory systems is interesting, but it does not establish a predictable benefit in people or make a capsule equivalent to a varied plant-rich diet.
Read the evidence limits and sources
NIH guidance finds little evidence supporting quercetin for exercise or athletic performance. A randomized exercise study also found no significant benefit for the performance measures assessed. These findings should temper broad endurance, recovery or immune claims and do not establish efficacy for this finished product.
