Quercetin supplementation reduces systemic inflammation (specifically TNF-α, IL-6, and CRP) in humans, which may mitigate risks associated with obesity and type 2 diabetes.

If you are looking to reduce inflammation associated with obesity or metabolic risk, quercetin supplementation (150mg daily for 6 weeks) has been shown in human studies to lower TNF-α levels. This is distinct from dietary intake, which is often much lower. Consult a doctor before starting, especially if you have existing health conditions.

Why this rating

The paper cites one human study (Ref 30) but relies heavily on in vitro and animal models for mechanistic details, limiting the strength of human-specific claims.
