Red seaweed, particularly species such as Gracilaria and Gelidium, has a long history of traditional use in East Asian countries as a food and remedy for digestive complaints, including constipation in children and adults. The primary mechanism attributed to its use is its high content of soluble dietary fiber, especially agar and carrageenan, which are polysaccharides known for their gel-forming and bulking properties. These fibers can absorb water, increase stool bulk, and promote bowel movements, similar to the way other fiber supplements function.

However, while the traditional use of red seaweed for constipation is well documented in folk medicine and traditional dietary practices, direct scientific studies specifically evaluating its efficacy in treating childhood constipation are limited. Most of the available evidence relates to the general laxative effects of agar and other seaweed-derived fibers, which have been shown in some clinical and laboratory settings to increase stool frequency and improve bowel habits in adults. There is a lack of high-quality, controlled studies focused on children or on specific red seaweed species.

In summary, the use of red seaweed to support or treat constipation in children is primarily supported by traditional practices and the known physiological effects of its fiber content, but robust scientific validation for this specific indication and population is lacking.
