Carrageenan Versus Poligeenan Versus Irish Sea Moss
Carrageenan and Irish Sea Moss are both derived from types of red algae—as is Gold Sea Moss—but their composition and uses differ significantly.
Carrageenan: The Stabilizer
Carrageenan is a commercially processed extract used primarily as a thickening and stabilizing agent in foods, cosmetics, and pharmaceuticals.
It’s prized for its ability to create a smooth, gel-like consistency and improve product texture.
Food-grade carrageenan is not absorbed from the intestinal tract and passes through unchanged, functioning like fiber.
It is never injected into the human body.
Where the Confusion Started: Poligeenan
Over the years, concerns have been raised about carrageenan’s safety, but digging deeper reveals the true cause: Poligeenan, not food-grade carrageenan.
Poligeenan is a chemically altered version of carrageenan, created under very harsh conditions (pH < 2 and temperatures > 80°C).
It is absorbed by the body and has shown digestive issues in animal studies.
Important:
Poligeenan is never used in food products.
Studies linking carrageenan to health risks are actually based on Poligeenan, not the carrageenan found in your food.
Regulatory bodies worldwide, including the FDA and the European Food Safety Authority, continue to list food-grade carrageenan as safe for human consumption under standard dietary protocols.

Irish Sea Moss: The Ancient Superfood
Irish Sea Moss, also known as Chondrus Crispus, has been revered by human cultures for over 14,000 years.
Archaeological evidence traces red seaweed’s medicinal use back to 600 BC in China.
It was a vital food source during the Irish Potato Famine in the 1840s.
Native to the Atlantic coasts of Europe and North America, Irish Sea Moss is rich in 92 of the 102 minerals our bodies need.
It’s known for:
Supporting immune function
Promoting digestion and gut health
Enhancing skin, hair, and nail vitality
Balancing thyroid function and mood
Rather than being isolated, extracted, or processed, Irish Sea Moss is typically consumed in its whole form—as gels, capsules, powders, or added to smoothies, teas, and meals.
At Human Garage, we advocate the use of Irish Sea Moss in its purest form, which we outline in our 🔗 Supplement Guide.
Summary at a Glance
Carrageenan | Poligeenan | Irish Sea Moss | |
|---|---|---|---|
Source | Red algae (processed extract) | Chemically degraded carrageenan | Red algae (whole food) |
Use | Thickener in food, cosmetics | Lab research only (not used in food) | Nutritional supplement, healing food |
Safety | Safe, approved worldwide | Absorbed, linked to inflammation (lab studies) | Highly nourishing, natural remedy |

Final Word
There’s no controversy when science is correctly understood:
Food-grade carrageenan is safe and remains a vital stabilizer in many products.
Poligeenan is a chemically altered version not used in foods and should not be confused with carrageenan.
Irish Sea Moss, meanwhile, continues to be one of nature’s most complete, healing foods—supporting vitality across the body at the mineral and cellular level.
When we align with nature and nourish the body properly, it knows exactly how to heal itself.
