►Ever since we began developing health supplements 16 years ago, our researchers have persistently studied the
 efficacy of our supplements against the following illnesses:

Hepatitis B and C, fatty liver, NASH (nonalcoholic steatohepatitis), drug-induced liver injury, autoimmune hepatitis, alcohol-induced hepatitis, liver cirrhosis, liver cancer, acute and chronic nephritis, diabetic renal injury, kidney cancer, bladder cancer, colds, and influenza.

We have conducted extensive research throughout the world including the countries in Asia, Europe, North and South America, and North Africa.

Our research and findings have been presented 34 times at International scientific conferences and medical conventions and have been published in academic journals five times. Thousands of liver patients have voluntarily provided testing data for our studies in cooperation with participating doctors and researchers.

All of our health supplements are manufactured and sold exclusively by Kyotsu Jigyo, Inc. in Tokyo, Japan.

Please be aware of imitations on the market. They may appear similar to our products but they have not undergone the same extensive research, testing and studies as our health supplements have.

For more information on our health supplements, please visit the Kyotsu Jigyo website at
