This product is a plant-based dietary formulation built around konjac root, a traditional ingredient derived from the corm of the Amorphophallus konjac plant. The konjac root is processed into a fine powder and filled into vegetarian capsules for straightforward, measured intake. The konjac used in this formula is selected from mature roots grown under controlled agricultural conditions. After harvest, the roots are cleaned, peeled, and subjected to a low-temperature drying and grinding process that preserves the natural plant material in a stable powdered form. The powder is screened for particle size uniformity to support consistent capsule filling and product homogeneity. Each capsule is produced in a food-grade manufacturing environment that follows good manufacturing practices. Quality checks include raw-material identification, microbial testing, moisture analysis, and heavy-metal screening to verify that the finished product meets established food-safety limits. Batch records are retained to support full traceability from source to finished goods.
