The Claim

Sulforaphane is the first identified naturally occurring antagonist of the human steroid and xenobiotic receptor (SXR/hPXR), a nuclear receptor that regulates the expression of drug-metabolizing enzymes.

Description
1 study reviewed
In plain English

Sulforaphane is a compound found in nature that directly blocks the human SXR/hPXR receptor, which controls the production of enzymes that break down drugs and toxins.

See the scientific wording

Sulforaphane is the first identified naturally occurring antagonist of the human steroid and xenobiotic receptor (SXR/hPXR), a nuclear receptor that regulates the expression of drug-metabolizing enzymes.

Why this might work

Sulforaphane attaches to a specific receptor in liver cells that normally turns on enzymes to break down drugs. When sulforaphane binds, it blocks the receptor from activating the gene that makes the CYP3A4 enzyme. Without this enzyme, the liver cannot process certain drugs as quickly.

  1. Study: The Dietary Isothiocyanate Sulforaphane Is an Antagonist of the Human Steroid and Xenobiotic Nuclear Receptor

    Sulforaphane, a compound in broccoli, was found to block a human body receptor that normally turns on liver enzymes to process drugs. This is the first time a natural substance has been shown to do this.
