Why you need it

Gastro-Assist brings together five clinically studied ingredients that address gut health from multiple angles simultaneously — targeting the gut lining, microbial balance, immune modulation, and mucosal protection in a single formula:

• Mastic Gum (Pistacia lentiscus) 260mg — a resinous sap from the mastic tree of the Greek island of Chios, used in Mediterranean traditional medicine for thousands of years for digestive health. Mastic gum has been extensively studied for its activity against Helicobacter pylori and its ability to support gastric mucosal integrity, reduce gastric discomfort, and promote a healthy stomach lining
• Bifidobacterium longum BB536® 10 Billion CFU — one of the most extensively clinically studied probiotic strains in the world, with over 40 years of research. BB536® is a human-origin strain with documented benefits for gut flora balance, immune modulation, bowel regularity, and intestinal barrier function. The ® designation indicates this is the authentic, proprietary Morinaga strain
• Saccharomyces boulardii 5 Billion — a beneficial probiotic yeast (not a bacterium) that is naturally resistant to antibiotics, making it particularly valuable during or after antibiotic use. S. boulardii supports healthy gut flora balance, helps maintain intestinal barrier integrity, and has been clinically studied for traveller's diarrhoea, antibiotic-associated diarrhoea, and C. difficile prevention
• Zinc L-Carnosine 37.5mg (yielding 8mg zinc, 73% DV) — a chelated complex of zinc and the dipeptide L-carnosine that has a unique affinity for the gastric mucosa. Unlike standard zinc supplements, zinc L-carnosine adheres to the stomach lining and releases slowly, providing sustained mucosal protection, supporting gastric ulcer healing, and helping to maintain the integrity of the gut epithelial barrier
• Chamomile Extract 4:1 (Matricaria chamomilla flower) 200mg — equivalent to 800mg of dried chamomile flower. Chamomile's apigenin and bisabolol content provide anti-inflammatory, antispasmodic, and carminative properties — soothing intestinal smooth muscle, reducing cramping and bloating, and supporting a balanced intestinal inflammatory response

Key benefits

• Mastic gum — gastric mucosal support, H. pylori activity, traditional digestive remedy
• BB536® probiotic — 10 billion CFU of the world's most studied Bifidobacterium strain
• S. boulardii — antibiotic-resistant probiotic yeast for gut flora balance and barrier integrity
• Zinc L-carnosine — sustained-release mucosal protection and gut epithelial barrier support
• Chamomile extract — anti-inflammatory, antispasmodic, and carminative gut soothing
• Vegan, non-GMO, GMP certified — FDA and Health Canada standards
