A broad chemical category describing long chains of sugar molecules linked together; starch, cellulose, and many plant gums and mushroom-derived compounds are all polysaccharides.
Why it’s used
Listed on a label this generically, it likely refers to a specific plant or fungal extract valued for its carbohydrate structure, but the term itself does not specify which one or what it is taken for.
What the evidence says
Because 'polysaccharide' names a chemical class rather than a specific substance, no single body of clinical evidence applies to it as labeled. Some individual polysaccharides, such as those from certain mushrooms or oats, have their own separate evidence bases, but that evidence cannot be assumed to apply to an unspecified polysaccharide.
