While the human gastrointestinal tract is protected by a sophisticated mucosal lining, its physiological footprint is frequently compromised by modern dietary stressors, chronic low-grade inflammation, and the pervasive use of processed foods. Unfortunately, when this delicate barrier is disrupted, the underlying epithelial tissues become vulnerable to persistent irritation and mechanical stress. NOW Supplements Slippery Elm (Ulmus rubra) presents a clinical-grade, evidence-based botanical solution, utilizing the inner bark of the Slippery Elm tree to deliver a dense matrix of bioactive mucilage. Designed for proactive individuals seeking to soothe gastrointestinal discomfort and reinforce mucosal resilience, this advanced 100-capsule formula helps maintain digestive harmony and epithelial integrity already within a normal physiological range.
The Science of Botanical Demulcent Action
Unlike standard fiber supplements that primarily provide mechanical bulk, Slippery Elm acts as a potent botanical demulcent. Upon contact with the water present in the digestive tract, the complex polysaccharides (mucilage) contained within the inner bark rapidly hydrate, forming a viscous, gel-like matrix. This bio-active gel provides a physical and chemical barrier that adheres to the sensitive tissues of the stomach and intestinal lining, buffering them against the corrosive effects of gastric acid and digestive enzymes.
Mucosal Barrier Modulation: The complex mucilage polysaccharides naturally stimulate the local production of protective mucous, acting as a structural “patch” for the digestive epithelium and supporting the maintenance of tight junction health.
Sensory Modulation: By coating the sensitive nerve endings within the gastrointestinal submucosa, Slippery Elm supports the maintenance of “gut comfort,” naturally mitigating the sensation of localized irritation or burning.
Antioxidant Synergy: Beyond its physical buffering action, the inner bark contains specific procyanidins and tannins that provide localized antioxidant defense, neutralizing reactive oxygen species (ROS) and supporting the tissue-repair pathways of the epithelial lining.

Usage Guide
Take two (2) capsules one to three times daily with a full 8-ounce glass of water. Because Slippery Elm relies on hydration to form its soothing mucilage barrier, adequate daily water intake is clinically mandatory to facilitate the gel-forming process in the gut. If you are currently taking prescription medications, take Slippery Elm at least 2 hours before or after your medication, as the demulcent coating may potentially alter the systemic absorption rates of other pharmacological agents.
Safety Information
This botanical extract maintains a highly favorable safety profile for healthy adults. However, its demulcent nature requires clinical awareness regarding absorption protocols. Due to its potential to coat the intestinal mucosa, it should not be taken simultaneously with essential medications. Pregnant or nursing women must seek clinical guidance before initiating any new botanical regimen. Discontinue use if persistent gastrointestinal discomfort or unexpected allergic response occurs.
