Peak BioBoost is a doctor-formulated prebiotic fiber supplement created by Peak Biome. It’s designed to improve digestive regularity, soften stool, and reduce bloating—without harsh stimulants or laxatives. Unlike probiotics, which add good bacteria to your gut, prebiotics are the “food” that nourish and stimulate the growth of those good bacteria already present in your digestive tract. Peak BioBoost combines several plant-based, non-GMO prebiotic fibers with other gut-friendly compounds to support microbiome health.
