Iota-Carrageenan (I-C) is a sulfate polysaccharide synthesized by red algae, with demonstrated antiviral activity and clinical efficacy as nasal spray in the treatment of common cold. In vitro, I-C inhibits SARS-CoV-2 infection in cell culture.

Carrageenans or carrageenins (/ ˌkærəˈɡiːnənz / KARR-ə-GHEE-nənz; from Irish carraigín 'little rock') are a family of natural linear sulfated polysaccharides. They are extracted from red edible seaweeds. Carrageenans are widely used in the food industry, for their gelling, thickening, and stabilizing properties.

Iota-carrageenan is a polysaccharide that reveals antiviral activity by binding to viruses, inhibiting its replications and, consequently, its viral propagation. This systematic review of the literature aims to compare the effectiveness of an iota-carrageenan nasal spray to placebo.

5 days ago · Iota-carrageenan is an ideal prophylactic treatment for the common cold and is safe for use in children. Treatment of common cold with iota-carrageenan has to date been studied in five placebo-controlled clinical trials and these trials support both efficacy as a prophylactic treatment for colds and the safety and tolerability of iota-carrageenan.

Iota-carrageenan is one of a family of naturally occurring gel-forming sulfated polysaccharides and is well-known as a food additive. It is currently undergoing a Phase 2 clinical trials as a nasal spray for the potential prevention and treatment of viral pneumonia caused by SARS-CoV-2 or other respiratory viruses [299] , or for treatment of ...

Dec 26, 2024 · Iota carrageenan (ι-carrageenan) forms elastic, flexible gels when in the presence of calcium ions. It provides a softer, more flexible gel compared to Kappa carrageenan, making it ideal for applications requiring a gel-like consistency but with more pliability.

NCX 4240 is Carragelose (iota-carrageenan), a sulfated galactose polymer derived from red seaweed with antiviral properties. Carragelose inhibits viruses from binding to and entering human cells, reducing viral replication and associated symptoms.

Iota-carrageenan (IC), a natural linear sulfated polysaccharide extracted from edible red seaweed, can be used as a potential agent for prevention and management of a broad range of respiratory viral infections, including SARS and COVID-19 [8, [12], [13], [14], [15], [16]].

Jan 14, 2025 · Iota Carrageenan: Known for forming softer gels, Iota is perfect for applications that require a smooth, creamy texture, such as plant-based dairy alternatives and certain sauces.

Apr 24, 2015 · Iota forms a soft elastic gel especially in the presence of calcium ions (EU) and the resulting gel strength is ionic strength dependent. Unlike kappa, iota-carrageenan forms gels with freeze-thaw stability and is less likely to undergo syneresis.
