Irish Moss

Chondrus crispus
seaweeddemulcentgutthroatiodineminerals

Irish moss is a seaweed used as a soothing, gel-forming food and traditional remedy for throat and digestive comfort. When prepared as a gel, it acts like a demulcent—coating and soothing. Because seaweeds can contain iodine and can vary in heavy metal content, sourcing and moderation matter.

Key Benefits

Common Issues It May Help With

How To Use (Simple)

Taste / Notes

Mild ocean/sea taste; mostly neutral in smoothies.

Evidence Level

Demulcent effects are consistent with its gel-forming polysaccharides. Clinical evidence for specific outcomes is limited; best framed as supportive and food-like.

Cautions

Moderation matters due to iodine and sourcing variability. Use caution with thyroid disorders or iodine sensitivity. Choose reputable sources to reduce contamination risk. Pregnancy/breastfeeding: use conservative food-level amounts unless clinician-guided.

Interactions

May affect thyroid management if iodine intake is high—monitor if on thyroid medications Gel/fiber may reduce absorption of medications if taken together—separate by 2 hours If on anticoagulants, seaweed vitamin/mineral content varies—keep intake consistent
