Since the Coupang Rocket Overseas launch, NZ Origin has seen as much as a 65% month-over-month increase in sales

The origin story: A brand of pride and purpose anchored in the U.S., expanding worldwide
NZ Origin Inc. was founded in Cerritos, CA to launch Dr. Brian, the first in-house brand developed by US Pharmatech Inc. – a U.S.-based manufacturer in Las Vegas, NV specializing in health supplements. The brand’s namesake and co-creator, Dr. Brian Roettger, has been a pioneer in nutritional science and bio-hormonal health since 1977. His guiding philosophy combines scientific rigor, high-quality ingredients and advanced manufacturing to produce superior supplements.
The Dr. Brian brand holds deep significance as US Pharmatech Inc.’s first in-house venture – a milestone built on decades of expertise.
“Dr. Roettger firmly believes that the foundation of high-quality dietary supplements lies in the synergy between scientific research, world-class ingredients and advanced manufacturing technology,” said Dongjun Lee, CEO of NZ Origin Inc. “While he embraces innovation and adapts to the ever-evolving lifestyles of modern consumers, he emphasizes that true excellence begins with a commitment to fundamentals. This philosophy remains at the heart of the brand, which continues to grow under his guidance and vision.”

The Coupang connection: growing fast
NZ Origin, which has gained brand recognition in Korea in brick-and-mortar stores, launched on Coupang in 2025. “This collaboration is especially synergistic,” says Lee, noting that NZ Origin’s facility in Cerritos, CA is closely located to Coupang’s U.S. fulfillment center in Riverside, CA.
“The growth is a result of the strong brand recognition of Dr. Brian combined with the powerful reach of Coupang’s Rocket Overseas service,” Lee said. “Our goal is to become one of the leading health supplement brands within Coupang’s Rocket Overseas category.”

Coupang, which is based in Seattle and serves millions of customers in Korea, Taiwan, Japan and other markets, helps American businesses open direct sales channels into Asia, allowing them to grow their revenue by reaching new customers. Coupang helped drive the sale of more than $5 billion in U.S. goods and services in overseas markets in 2025, and uses innovative technology and logistics support to deliver an exceptional shopping experience for its customers.
“Coupang is effectively bridging the gap between American producers and global consumers,” said Vice President Bill Anaya. “By providing an AI-driven gateway to international markets, we’re helping everyone from small businesses to established brands like NZ Origin and Dr. Brian scale beyond their borders. It’s about more than just sales; it’s about giving U.S.-based entrepreneurs the tools to grow their revenue internationally so they can continue to invest in their people and communities at home.”
Why quality is the brand’s north star
Dr. Brian supplements are manufactured by US Pharmatech Inc. in Las Vegas, where a team of approximately 150 employees supports the company’s extensive portfolio which includes tens of thousands of proprietary formulations and collaborations with well-known brands. US Pharmatech Inc. maintains a strong global presence with key operations in Korea, Japan, China and other countries.
As a distribution company directly operated by the health supplement manufacturer itself, NZ Origin is able to stay true to the core philosophy of the brand without compromise, Lee said.
“The fact that it represents the manufacturer’s own brand serves as a strong advantage, offering clear trust and assurance in both quality and integrity,” Lee said. “We believe it’s essential to carefully select only high-quality ingredients and raw materials – as if we were preparing supplements for our own families.”

What Coupang means to NZ Origin
“Being listed as a Coupang-partnered brand in itself has significantly strengthened consumer confidence and laid a solid foundation for long-term growth in the Korean market,” Lee explained. “For U.S. companies considering entry into Korea, we highly recommend leveraging Coupang’s fast logistics, robust marketing infrastructure, and strong consumer trust as a powerful gateway into the market.”
Lee emphasized three things about working with Coupang: first, fast and reliable logistics; second, robust marketing and customer support infrastructure; and third, a powerful sales channel. “Coupang is, in many ways, a ‘channel that sells,’ ” Lee said. “It consistently drives strong sales performance across virtually every product category.”
