DUOLAC Launches ‘Probiotics with Strong Survivability’ Advertising Campaign

Korea’s leading probiotic brand, DUOLAC, has launched a new advertising campaign titled “DUOLAC, Probiotics with Strong Survivability.” The campaign highlights how many probiotics are lost during digestion — a problem DUOLAC calls “probiotic loss” — and introduces DUOLAC’s Dual Coating technology, designed to help more probiotics survive and safely reach the intestines.

The newly released TV commercial opens with Kang Ji-young asking, “Not feeling the benefits of probiotics as much as you expected?” The ad then introduces “probiotic loss” as the reason why consumers may not fully experience the benefits of probiotics. It delivers the message: “DUOLAC locks probiotic loss — delivering up to 221 times higher intestinal survivability,” highlighting the brand’s proprietary technology.

Many consumers choose probiotics based on the “guaranteed CFU count” listed on product labels. However, probiotics are living microorganisms, and a significant number are lost after exposure to harsh gastric acid (pH 2) and bile acids during digestion. According to Cell Biotech, the guaranteed CFU count only refers to the number of live probiotics maintained until the product’s expiration date before consumption, and differs greatly from the actual ability of probiotics to survive the digestive process and reach the intestines alive.

DUOLAC focuses on this issue by defining the loss of probiotics during digestion as “probiotic loss” and emphasizing the importance of survivability — the ability of probiotics to safely reach the intestines alive — rather than simply the guaranteed CFU count.

To overcome probiotic loss, DUOLAC focuses on improving delivery efficiency within the digestive system. The company applies its globally patented Dual Coating technology to all products, enabling probiotics to survive even in harsh gastric acid and bile acid environments. Through human clinical studies, DUOLAC demonstrated a probiotic survival rate of up to 91.6%, demonstrating intestinal survivability that was 221 times higher than non-coated probiotics.

Previously, DUOLAC collaborated with actor Son Suk-ku to introduce “intestinal survivability” as a new standard for high-quality probiotics. In this follow-up campaign, the brand explains why probiotic survivability matters through the new concept of “probiotic loss” in a more intuitive and persuasive way. By appointing former announcer Kang Ji-young — known for her professionalism and credibility — as the campaign model, DUOLAC further strengthened the campaign’s message and credibility.

A representative from Cell Biotech said, “This campaign was designed to introduce the concept of ‘probiotic loss,’ in which probiotics disappear during digestion, and to position DUOLAC as a probiotic brand with superior survivability achieved through Dual Coating technology.”

The representative added, “Good probiotics are not simply products containing large numbers such as 50 billion or 500 billion CFUs, but products equipped with technologies that can effectively deliver probiotics alive to the intestines.”

Meanwhile, Cell Biotech, the company behind DUOLAC, is Korea’s leading biotechnology company that pioneered the localization of probiotics after successfully mass-producing probiotics for the first time in Korea in 1995. DUOLAC, the company’s premium probiotic brand based on Dual Coating technology, has remained No.1 in Korean probiotic exports for 12 consecutive years.
