- Agar is a natural substance extracted from red seaweeds that are found in waters throughout the world. Agar, a tasteless substance, has been used as a food ingredient for centuries. Agar readily forms a gel and is used as a stabilizer, bulking, thickening and gelling agent, and food additive.
- Agar is a rich source of water-soluble, indigestible fiber. In the digestive tract, it absorbs water, increases bulk, and stimulates large bowel muscle contractions. Agar's most common therapeutic use has been as a laxative, and it has been used for decades as a daily treatment for chronic constipation. Agar is used in a variety of commercial applications, including production of cloth, paper, and cosmetics. More recently, agar has been used in scientific research laboratories to grow bacteria for use in experiments.
- Agar has been studied in several clinical trials as a possible treatment for newborn hyperbilirubinemia, a condition characterized by high levels of the pigment bilirubin in the blood. High levels of bilirubin may result in jaundice, which is a yellow color in the skin and whites of the eyes. Agar has also been investigated to determine if it might have a beneficial effect on glucose intolerance in type 2 diabetes mellitus.
