Irish sea moss has been around for centuries. The Irish used it during the Great Famine. Caribbean cultures swear by it for vitality. And now? Biohackers, nutritionists, and everyday health-conscious people are adding it to smoothies, teas, and skincare routines. But is it all hype? Or is there real science behind it?
What Is Irish Sea Moss?
Irish sea moss is a red algae found along the Atlantic coasts of Ireland, the UK, and North America. It’s packed with minerals—92 of the 102 that the human body needs. Think iodine, magnesium, calcium, potassium, and zinc. Basically, a natural multivitamin growing on the ocean floor.
The Benefits of Irish Sea Moss
1. Supports Gut Health
Gut health is everything. Irish sea moss contains carrageenan, a prebiotic fibre that feeds beneficial gut bacteria. Studies show it may help support digestion and soothe the gut lining. One study found that sea moss increased gut microbiome diversity, which is linked to better overall health.
2. Boosts Immunity
Rich in antioxidants and antimicrobial compounds, Irish sea moss may help the body fight off infections. Research suggests that sulfated polysaccharides in sea moss can enhance immune response and even inhibit viral replication.
3. Enhances Skin Hydration & Elasticity
Ever wonder why sea moss is in so many skincare products? It’s because it acts as a natural humectant, drawing moisture to the skin. Plus, it contains sulfur, which helps with acne, eczema, and other skin conditions.
4. Supports Thyroid Function
Iodine is critical for thyroid health, and Irish sea moss is one of the best natural sources. The thyroid regulates metabolism, energy levels, and even mood. If you’re low on iodine, your thyroid (and energy levels) might take a hit.
5. May Aid in Muscle Recovery
After a workout, your muscles need minerals to recover. Irish sea moss provides potassium, magnesium, and amino acids—all crucial for muscle repair. Some athletes use it as a natural post-workout recovery aid.
How to Use Irish Sea Moss
It usually comes in two forms: dried or gel. You can soak dried sea moss and blend it into a gel to add to smoothies, soups, and teas. Some people even take it in capsule form for convenience.
What Does it Taste Like?
Yeah, a little. But when mixed into a smoothie or soup, the taste is mild and almost unnoticeable.
The Science (Without Going Overboard)
- A study published in Marine Drugs found that Irish sea moss contains bioactive compounds that promote gut health and immunity.
- Another study in Nutrients suggested that seaweed polysaccharides, like those in Irish sea moss, may help regulate blood sugar levels and reduce inflammation.
- Traditional use of sea moss dates back centuries, but modern research is catching up—highlighting its role in thyroid support, digestion, and overall wellness.
Should You Try It?
If you’re looking for an all-natural way to support gut health, immunity, and recovery, Irish sea moss is worth considering. It's nutrient-dense, versatile, and backed by both history and emerging science.
