Capsule #2: Soothing Fiber Formula

Soothing Fiber Formula, a gentle, plant-based soluble fiber, coats and soothes the GI lining to support comfortable regularity and balanced bowel function, and in the PlexusDx Gut Health Support pack it works alongside the probiotic and glutamine to support a healthier gut microbiome and a calming, well-supported digestive system; the supplement features aloe vera, marshmallow root, and slippery elm to support digestive comfort and healthy regularity—especially for sensitive digestion—and its rich, naturally mucilaginous compounds help coat and calm the gastrointestinal lining, supporting stool consistency whether you’re dealing with occasional constipation or loose stools, while being an easy-to-take daily capsule that also supports a healthy gut environment as part of an overall wellness routine and is made without common allergens or additives, containing no dairy, gluten, salt, wheat, sugar, yeast, corn, soy, fish/shellfish, nuts, or sesame.†
