With the EGCG compound, green tea has become the king of refreshment beverages.

Found at levels as high as 59.1 percent, EGCG gives green tea its sharp character and delivers a long list of health benefits that appeal to today’s consumers.

A Compound With Real Impact

EGCG occurs naturally in green tea leaves. It supports stress relief, reduces fatigue, and refreshes the body on hot days, which makes it a trusted companion for young people who enjoy outdoor activities and summer trips. As a strong antioxidant, it helps calm the mind, strengthen immunity, slow aging, and lower cholesterol.

Research has also linked EGCG to reduced risks of lung cancer, colorectal cancer, breast cancer, and prostate cancer. These diseases claim about 205 Vietnamese lives each day. EGCG further contributes to heart health, helping lower the risk of heart attacks, strokes, and high blood pressure. These conditions remain the leading causes of death in Vietnam and are affecting younger age groups more often.

The Brand Consumers Trust Most

According to a recent Nielsen survey, nearly 80 percent of consumers believe Zero Degree Green Tea (Trà Xanh Không Độ) has the most recognizable bitterness and aroma among bottled teas. Nielsen data also shows that the brand holds a strong position in the category, backed by broad consumer approval.

What Sets Zero Degree Green Tea Apart

Zero Degree Green Tea (Trà Xanh Không Độ) is a familiar beverage for millions of consumers both in Vietnam and abroad.

Trần Uyên Phương, Deputy CEO of Tan Hiep Phat, explains that the brand’s success comes from three core elements: the ingredients, the technology, and the people behind the product.

Zero Degree Green Tea uses an Aseptic cold filling system overseen by specialists. This process helps the product retain the highest levels of beneficial nutrients from Thai Nguyen tea leaves, especially EGCG, which gives the tea its signature edge.

Natural ingredients are paired with a five-step Aseptic process that sterilizes the bottle, cap, water, product, and filling environment. This combination preserves flavor, nutrients, and EGCG without the need for chemical preservatives. The approach aligns with current consumer concerns. According to Nielsen, 70 percent of Vietnamese consumers try to avoid preservatives, 68 percent avoid artificial colors, and 65 percent refuse artificial additives.

International Recognition and Market Leadership

The EGCG compound in Zero Degree Green Tea helps ease stress and fatigue, allowing young people to enjoy every moment of life.

The sealed, sterile production line and cold filling technology helped Zero Degree Green Tea receive FDA certification from the United States Food and Drug Administration. The product maintains high nutritional value, a clean natural flavor, and does not rely on preservatives or industrial colorings. It is also designed with environmental responsibility in mind.

These qualities have earned remarkable consumer loyalty. Seventy-one percent of survey respondents say they drink the tea regularly. Seventy-six percent believe it is made from natural ingredients, and 69 percent trust that it supports better health. By mid-2016, Zero Degree Green Tea reached a 38 percent market share, the highest in the bottled tea segment.

Sustaining Leadership Through Quality

With natural Thai Nguyen tea leaves and one of the most advanced Aseptic systems in the world, the brand captures the highest EGCG content possible in each bottle. This commitment to quality has allowed Zero Degree Green Tea to hold its lead far beyond the usual life cycle of a beverage product. For more than a decade, it has remained the top bottled tea in Vietnam.
