Through decades of consistent scientific leadership,  ILHWA developed the world’s most efficacious and balanced ginseng extract.
GINST 15 - 21st Century Korean Ginseng™ from ILHWA

Through continuous scientific research and development for more than four decades, Ilhwa has become the World Leader in Ginseng Science. The company is driven by a single passion…to bring wellness to humanity across the globe through this incredible herb.

In 1981 Ilhwa created a research and development center, applying the best in scientific research to create breakthroughs in Ginseng growth, harvesting, processing and extraction. This was a first in ginseng science.

Today, Ilhwa is a small high tech pharmaceutical and nutraceutical company with 3 divisions: Ginseng, Pharmaceutical and Beverage. They are fully KFDA compliant and GMP and ISO certified, holding numerous patents and the publications of 100’s of papers and clinical studies. lhwa utilizes the best that modern science has to offer in all of its research and development.

At the same time, it carefully honors and respects the integrity of this remarkable root, which has been used for 5,000 years to heal the human body.

Ilhwa creates the world’s leading 20th century ginseng extract…

Utilizing the best in scientific practice, Ilhwa paid close attention to the experience of customers, doctors and their patients. Through decades of consistent scientific leadership, lhwa developed the world’s most efficacious and balancing ginseng extract.

Ilhwa uses whole root processing without peeling, utilizing its own proprietary low heat vacuum extraction. The roots are harvested at the optimum time of 4 to 5 years.

Most companies use the traditional 6 year harvested root which is more fibrous and possesses less ginsenoside density and balance.

GinST 15…the advanced High Absorption ginseng extract for the 21st Century

Although Ilhwa had created the most efficacious and balanced ginseng, there were still mixed results. The problem was absorption

The unique active ingredient in Ginseng are plant saponins called ginsenosides. Ilhwa science discovered that ginsenosides are absorbed in the lower intestine. For many people this meant poor absorption and less efficacy. Ilhwa began research to a create Ginseng extract which would deliver a much higher, more consistent, and faster absorption in the human body.

Ilhwa developed a proprietary fermentation process to solve the problem.

The result…GinST 15. The Ginseng with 15 times greater absorption and 4 times faster absorption.

The GinST 15 Objective:  Absorption in the body

Ginseng’s unique active ingredient ginsenosides, possess important medicinal properties. Key ginsenosides from ginseng extract are not fully absorbed until they reach the lower intestine


After Ginseng is consumed, natural ginsenosides enter the stomach and small intestines without being digested. When they enter the large intestines, the beneficial bacteria residing in the large intestines play a very important role in metabolizing natural ginsenosides into highly absorbable compounds.

Consistent Absorption

With standard ginseng extract each individual possesses different capability in metabolizing ginsenosides. Absorption is inconsistent, and there is a wide range of average times in reaching the maximum plasma concentration.
In addition, only a small amount of ginseng extract is absorbed. When GinST 15 extract is taken, absorption is approximately 4 times more consistent


The GinST-15 Solution

As the world leader in ginseng science, Ilhwa was determined to find a solution to this problem of absorption, and in 1999 they secured 2 patents for creating ginseng extract metabolites via human bacteria. They continued their diligent work in the next decade developing a high yield enzyme fermentation process with their famous ginseng extract creating 2 more patents in 2009 and 2010.   
GinST 15, the 21st Century Ginseng was born.
When GinST 15 extract is taken, a far larger amount is absorbed in the blood compared to standard ginseng extract. (15 times more AUC)
The GinST 15 extract provides 4 times faster absorption than standard ginseng extract.

KFDA Functional health claim   

Many studies have been done on GinST 15 which is shown in research via its metabolite marker IH901 and Compound K. One of the areas where Ilhwa has created numerous studies is energy creation, blood glucose and blood lipid management.
Il Hwa’s research is so substantial that they received a KFDA certification for a functional health claim for blood glucose management

Absorption over time

Regular ginseng extract takes 12 hours to get maximum absorption while Gin ST15 extract will get maximum absorption in 3 to 4 hours. This illustrates the far greater absorption of GinST 15.
(Please Note: the scale of 0-50 ng/ml for Ginseng Extract and 0-300ng/ml for GinST 15. A different scale for each had to be used so that a comparison can be seen.)
