The Claim

In mouse and human macrophages, 1,25-dihydroxyvitamin D suppresses the inflammatory response to bacterial lipopolysaccharide by inhibiting NF-κB activation, which reduces transcription of the microRNA-155 gene, thereby increasing levels of the anti-inflammatory protein SOCS1 and enhancing negative feedback regulation of Toll-like receptor signaling.

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

How it works
1 study reviewed
In plain English

A form of vitamin D can calm down immune cells when they overreact to bacteria by turning off a key inflammation signal, which helps produce a protein that puts the brakes on the immune response.

  1. Study: 1,25-Dihydroxyvitamin D Promotes Negative Feedback Regulation of TLR Signaling via Targeting MicroRNA-155–SOCS1 in Macrophages

    Vitamin D helps calm down the immune system’s overreaction to bacteria by turning down a gene (miR-155) that blocks a natural brake (SOCS1) on inflammation. This lets the body stop the inflammation faster.
