Irish Sea Moss
herbs
Irish sea moss (Chondrus crispus) is a nutrient-dense red algae rich in minerals, iodine, and polysaccharides traditionally used in Irish cuisine. It is marketed as a thyroid support and immune-boosting supplement, though human clinical evidence remains limited. The supplement provides bioavailable minerals but requires more rigorous research to substantiate many popular health claims.

Limited human clinical trials exist for Irish sea moss; most evidence is derived from test-tube and animal studies or traditional use.

The supplement is generally recognised as safe when sourced from reputable suppliers and consumed in appropriate quantities, but regulatory oversight of quality and contamination varies significantly.
