Concentration & Optimizing Process

Intensifying Ginseng's Energy

Preserving ingredients through JungKwanJang's unique temperature and time.

Focusing on one single ingredient, ginseng, we apply our knowledge to best extract and maximize its benefits from each of our processing stages. Our know-how on the production process, optimized temperature, optimized time in each of its stages come together to enrich ginseng components, quality, and flavor. A combined application of MSCE* & MBE** processes along with our extraction experience makes our ginseng extract unlike any other.

*MSCE: Multi-Stage Countercurrent Extraction

**MBE: Modified Batch-Type Extraction

We have set our internal standard with ginseng's 13 Ginsenosides and Red Ginseng Polysaccharides. Setting such higher efficacy standard is what makes us different. Although this makes the processing and stable production hundred times more difficult, this is what makes our raw ingredient more potent and efficacious than our competition.

Ginseng's natural variability makes this feat challenging, particularly with the complex standardization of red ginseng polysaccharides. This achievement sets G1899 apart, showcasing our unparalleled dedication and competitive edge.

Our own standardization and scientific findings are back by our in-house research team and 3rd party medical communities.
