Many young people always keep a bottle of Number 1 on their desk. For them, “energy” is no longer just about staying awake. It is about fueling themselves with clean energy to stay passionate every day.

Facing long standing assumptions that energy drinks must contain preservatives, Number 1 has spent more than two decades reshaping that belief.

The brand not only delivers real energy, but also sets the standard for preservative free energy drinks, leading the movement toward clean energy for Vietnamese consumers.

What does Gen Z expect from an energy drink?

In a world defined by pressure and speed, “energy” is not just about staying awake. It is a declaration against fatigue. It is the right and clean way to fuel up, giving people the power to keep breaking limits without paying a price.

Gen Z seeks products without preservatives, something that boosts energy while still being responsible toward both their bodies and the environment. According to Nielsen, 70 percent of Vietnamese consumers say no to preservatives, and 8 out of 10 are willing to pay more for preservative free products. Most of them belong to Gen Y and Gen Z, generations that prioritize health and sustainability.

The modern Aseptic cold fill production line at the Number 1 factory is where each bottle of energy drink is created with cutting edge “green” technology, preserving pure energy without the need for preservatives.

“I used to drink energy drinks just to stay awake. But after learning that Number 1 has no preservatives, I feel more at ease knowing I’m fueling my body the right way,” said Dang Linh, 27, a designer in Ho Chi Minh City.

For him, “energy” is not only for productivity but also for living fully, staying passionate, and living consciously. That has been the spirit Number 1 has followed for more than 20 years.

Why doesn’t Number 1 need preservatives?

Behind each bottle of Number 1 is a two decade journey rooted in one belief: “Nothing is impossible.”

In 2006, when Vietnam’s beverage industry still relied heavily on hot fill technology, Number 1 made a bold move by investing hundreds of millions of USD to bring in the Aseptic cold fill technology from global giant GEA. This technology is considered one of the biggest breakthroughs in the beverage world.

Aseptic is a game changer thanks to its cold fill method and absolute sterility across the entire process: bottles, caps, liquid, and environment. This allows Number 1 to keep flavor and nutrients intact without using preservatives.

Vincent Mauer, General Manager of GEA Vietnam and the Philippines, emphasized, “This method preserves nutritional value and flavor better than traditional pasteurization. It extends shelf life without preservatives and keeps quality stable to meet consumer preferences.”

For Number 1, Aseptic is not just the technology that enables preservative free drinks, but also a commitment to sustainable living.

According to Mauer, each seventh generation Aseptic production line can reduce water consumption by up to 91 percent. As a result, GEA customers like Number 1 save 97,500 cubic meters of water per year, equivalent to the annual water usage of 2,100 people.

Mr. Vincent Mauer, General Director of GEA Vietnam and the Philippines, shares insights on Aseptic cold fill technology.

“GEA focuses on reducing PET usage as much as possible, and this is where we can make the biggest impact,” he added.

He pointed out that in Vietnam, with seventh generation Aseptic technology, Number 1 has reduced bottle weight by 50 percent, from 27 grams to 13.5 grams, cutting CO2 emissions by 20 percent per bottle.

A single energy drink bottle becomes a choice for health, the environment, and the future.

More than just energy: Powering steady passion

“I film vlogs all night and drink a lot, so knowing that Number 1 has no preservatives makes me feel safe. It gives me instant energy with a strong but smooth taste, and helps me stay focused. That’s why I choose Number 1,” said Le Minh Quan (28, content creator, Dong Nai).

For Number 1, the goal has never been just “keeping you awake for a few hours.” A brand representative said, “We want our product to be a steady source of energy, a foundation that helps everyone build the ‘Number 1’ version of themselves.”

For two decades, Number 1 has stayed true to that mission, delivering real energy to real people.

For millions of young people, Number 1 is not only an instant source of alertness. It is the fire that keeps their passion alive, giving them the courage to move forward, to conquer challenges, and to become the “Number 1” version of themselves.

In 2016, Number 1 earned Halal certification for Islamic markets. In 2017, it received U.S. FDA certification, paving the way to expand across Asia and Europe and reinforcing the global standard of Vietnamese quality.

From night shift workers, students studying late, to office employees racing deadlines, everyone finds in Number 1 a clean and long lasting energy source that helps them push forward with confidence.

Each time you open a bottle of Number 1, you are choosing clarity, choosing passion, and choosing clean energy to go further. Because to create and maintain the “Number 1” version of yourself, choosing the right energy is always the first step.
