The Claim

8-Prenylnaringenin (8-PN) demonstrates the highest relative binding affinity for estrogen receptors compared to two other flavanones in competitive ligand binding assays, with preferential binding to ERα over ERβ.

Source: Assessment of the proliferative capacity of the flavanones 8-prenylnaringenin, 6-(1.1-dimethylallyl)naringenin and naringenin in MCF-7 cells and the rat mammary gland.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

A natural compound called 8-Prenylnaringenin (found in hops) attaches to estrogen receptors in the body better than two similar compounds, and it prefers one type of estrogen receptor (ERα) over another (ERβ).

See the scientific wording

8-Prenylnaringenin (8-PN) exhibits the highest relative binding affinity for estrogen receptors among the three flavanones tested, with a preference for ERα over ERβ in competitive ligand binding assays

What the research says

1 study

  1. Study: Assessment of the proliferative capacity of the flavanones 8-prenylnaringenin, 6-(1.1-dimethylallyl)naringenin and naringenin in MCF-7 cells and the rat mammary gland.

    The study directly tested what the claim says - it compared how well 8-PN and two other flavanones bind to estrogen receptors. The results showed 8-PN binds the strongest and prefers ERα over ERβ, exactly matching the claim.
