Transparent Labs Synbiotic is a once-daily, 3-in-1 gut health formula featuring a phage-based prebiotic (PreforPro®), four clinically studied probiotic strains, and a postbiotic immune activator (IMMUSE®).
Unlike fiber-heavy blends, our formula is gentle on sensitive stomachs—helping reduce bloating and digestive discomfort while promoting microbiome balance and supporting immune resilience. With 15+ human clinical trials behind the ingredients, Synbiotic delivers total microbiome support in one convenient, shelf-stable capsule.
