Algin

background

Algin is a polysaccharide (a type of carbohydrate) derived from brown seaweed (from the genera Ascophyllum, Macrocystis and Laminaria) currently found in the North Atlantic basin. Seaweed has been used as food for humans and animals for thousands of years. Its derivatives have wide application in the food industry, the cosmetic industry, and in medicine and dentistry. In Asia, seaweed is relied on as a vegetable and fiber source, while the Western world has developed a tablet form to get the nutrients.
In folk medicine, algin is taken by mouth to prevent and treat high blood pressure. It is also used in foods such as candy, gelatins, puddings, condiments, relish, processed vegetables, fish products, and imitation products. In manufacturing, algin is used as a binding and disintegrating agent in tablets, as a binding and demulcent in lozenges, and as a film in peel-off facial masks.
Algin is often used to normalize bowel function. It has also been studied in combination with dietary fibers. Additional study is needed before any firm recommendations can be made about the safety or effectiveness of algin.
