Swanson Tri-Fiber Complex is a fiber supplement combining psyllium husk, oat bran and apple pectin in one blend. Each type works differently in the gut: psyllium adds bulk, oat bran slows digestion, and apple pectin feeds beneficial microbes. It suits adults who fall short of the 25–29 g of daily fiber most guidelines recommend and want a single product instead of separate psyllium and bran supplements. Reviewers rate it highly, though some mention the texture and the need to drink plenty of water.

Tri-Fiber Complex is a dietary fiber supplement from Swanson. It combines three types of fiber: psyllium husk, oat bran and apple pectin. It is meant to add to your daily fiber intake.
Each type of fiber acts differently in the gut. Some slow the movement of food. Others feed beneficial gut microbes. Others add bulk to digestive material and support regular movement.
Dietary fiber supports cardiovascular health, including cholesterol and blood sugar levels already within the normal range. It also supports regular bowel function. Fiber can also support a diverse microbiome and feelings of satiety.
