GLG Life Tech Corporation was founded in 1999 on a quest to overcome common health issues of our times – among them, obesity and diabetes.


GLG’s corporate values are rooted in Dr. Zhang’s vision to bring healthier, natural, zero-calorie sweeteners to the world. As a clinical practitioner, Dr. Zhang gained experience in treating chronic diseases such as diabetes and heart disease. Through his clinical work and research, he came to believe that diet had a significant influence on both the spread and treatment of these chronic diseases. Indeed, a diet rich in sugary foods has proven to be linked to these diseases.

As a concerned Canadian citizen in the 1990s, Dr. Zhang began studying the stevia plant and its potential as a zero-calorie natural sweetener that could be used to promote his vision for a healthier society. Dr. Zhang’s goal is to develop stevia and other natural sweeteners, such as luo han guo, as mainstream, healthy ingredients for the global food and beverage marketplace in order to reduce the amount of sugar in our diets.

Dr. Luke Zhang’s


Over 15 years ago we began our quest to overcome two of the world’s most serious health issues—obesity and diabetes. We began our non-GMO stevia plant hybridization program back in 1997 because we had a vision for what the future of stevia could be.

We believe we’ve made a difference in today’s world by producing the highest quality and best-tasting stevia extracts on the market today. Partnering with us means you’re contributing to a healthier and thriving future.

Scientific research has tied high intake of added sugars to many poor health conditions, including obesity, high blood pressure, type 2 diabetes and other risk factors for heart disease and stroke. Sugar has come under increasing scrutiny, and governments are beginning to regulate sugar content in food and beverage products.

Market dynamics have seen a drastic decrease in market share for processed and synthetic sweeteners, as more scientific evidence points to their use as the cause of new diseases and health issues. Increasing demand, as seen by the LOHAS consumer group (Lifestyles of Health and Sustainability), is on the rise and growing.

Research shows that one in four adult Americans is part of this group — nearly 41 million people representing an estimated 290 billion dollar market. These consumers are the future of “food and beverage industry” and also the future of progressive social, environmental and economic change in this industry.
