CL-K1®

From fungal strain discovery to a standardized bioactive ingredient platform for metabolic health.

WHAT IS CL-K1®

CL-K1® stands for Ceriporia lacerata-K1, a natural-origin bioactive ingredient developed by Longrunn Medical through microbial strain research and fungal fermentation technology.

It originated from the study of Ceriporia lacerata, a fungal strain first identified during research on bioactive compounds from medicinal mushrooms. Through continued strain improvement, cultivation optimization, and standardization, CL-K1® has developed into a research-based ingredient platform for metabolic health.

CL-K1® is best understood as a multi-target cellular nutrition platform focused on glucose metabolism, insulin response, liver-related metabolic health, oxidative stress, inflammatory balance, and cellular energy regulation.

Process meaning: staged culture, quality testing, separation, concentration, and format-specific processing help position CL-K1® as a controlled bioactive ingredient platform.

Research Direction

Diabetes and Liver Metabolism

CL-K1® research focuses primarily on metabolic disorders, especially type 2 diabetes, impaired fasting glucose, insulin resistance, and liver-related metabolic dysfunction.

From a cellular perspective, these conditions are closely connected. Pancreatic beta-cell stress, impaired insulin signaling, liver glucose regulation, mitochondrial function, oxidative stress, and chronic inflammation all influence long-term metabolic balance.

CL-K1® is studied within this multi-target framework. Its research explores how fungal fermentation-derived bioactive compounds may support the cellular environment involved in glucose regulation, liver metabolism, energy production, and metabolic resilience

Current Application & Future Potential

CL-K1® is currently commercialized through EFILA-related health supplement, medical nutrition, and metabolic health applications. This creates a practical and regulatory-compliant path for market entry while continuing to build clinical, functional, and mechanistic evidence.

Its deeper value lies in its research foundation: fungal strain development, fermentation technology, safety data, patented strain assets, regulatory recognition, and a clear focus on diabetes and liver-related metabolic health.

With continued evidence development, CL-K1® has the potential to grow from a standardized health ingredient into a supportive therapeutic ingredient platform and a future biopharmaceutical development candidate.
