Based on our own and current literature data, we analyzed the prebiotic properties of polysaccha
rides and extracts of seaweeds. The role of prebiotics, particularly polysaccharides, in the normalization of
intestinal microflora is discussed; consideration is also given to the possibility of seaweed polysaccharide fer
mentation by colonic microflora and selective stimulation of the growth of colonic bifidobacteria. This review
also analyzes other useful properties of seaweed polysaccharides and discusses the prospects for inclusion of
seaweed polysaccharides in the composition of functional nutrition products for the purposes of correcting
intestinal bacterial disorders and inflammatory processes and normalizing the immune and metabolic status.
