The Claim

Vitamin D receptor signaling upregulates tight junction proteins and induces antimicrobial peptide expression, thereby enhancing intestinal barrier integrity and modulating T-regulatory cell differentiation to suppress autoimmune responses.

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

When your body uses vitamin D properly, it helps seal your gut lining and activates natural defenses that calm down overactive immune responses, which might prevent autoimmune diseases.

See the scientific wording

Vitamin D receptor signaling upregulates tight junction proteins and induces antimicrobial peptide expression, thereby enhancing intestinal barrier integrity and modulating T-regulatory cell differentiation to suppress autoimmune responses.

What the research says

1 study
  1. Study: Human cathelicidin antimicrobial peptide (CAMP) gene is a direct target of the vitamin D receptor and is strongly up‐regulated in myeloid cells by 1,25‐dihydroxyvitamin D3

    This study shows that vitamin D turns on a gene that makes a natural antibiotic in human cells, which helps protect the gut from germs. This supports the idea that vitamin D helps strengthen the body’s defenses.
