WONDERLAB’s Proprietary Strain GOLDGUT-M520 Leads a New Direction for Industry Development

Recently, WONDERLAB’s 6th Anniversary · “66 Gut Health Festival” sharing event was held in Shanghai. The event unveiled the patented star strain GOLDGUT-M520 for the four-layer intestinal barrier. Built on proprietary strains and an evidence-based research system, it advances gut-health management into a new scientific dimension of coordinated four-layer barrier action. At the event, the warm short film “Tailwind” starring WONDERLAB Beneficial Recommendation Officer Jin Jing premiered, using a true story to communicate the importance of gut health. Experts and users also shared their personal experiences, making the health improvements enabled by advanced microbiome science tangible and clearly showing how laboratory research can translate into everyday value at the dining table.

Addressing Local Gut-Health Challenges: All-in-One Probiotics 4.0 Engages Consumers with Clinically Supported Solutions

According to the China Residents’ Gut Health White Paper released by the National Health Commission in early 2024, gut-health problems are widespread among Chinese residents: 62.3% of adults have gut problems of varying severity, while only 21.5% undergo regular gut-health examinations.

At the event, the brand story short film “Tailwind,” filmed by WONDERLAB Beneficial Recommendation Officer Jin Jing, was officially presented. Based on real user stories, it shows urban white-collar workers and office employees facing gut problems after prolonged sitting, staying up late, and unhealthy eating habits, while also depicting how WONDERLAB All-in-One Probiotics 4.0 supports health management and turns challenges into a “tailwind” situation.

After the screening, experts, bloggers, guests, and users at the event recognized the film and shared their experiences using All-in-One Probiotics. Beauty blogger Feng Xue’er said: “Although I am a skincare specialist, I could not escape the health risks brought by frequent business trips and reversed day-night schedules. Persistent breakouts and constipation… five years ago, I nearly left the industry because of a series of problems caused by gut imbalance.” Office workers and bloggers are not the only ones troubled by gut problems; doctors and nutritionists also face them. Certified public nutritionist Gao Yuanyuan shared that although her daily routine is usually regular, she still struggles with an allergy-prone constitution and age-related metabolic concerns. The audience members who shared their stories had recognized their gut problems early, underwent regular health checks, and said they carried WONDERLAB All-in-One Probiotics with them to support their health management.

Mu Lei, a doctoral degree holder in gastroenterology and a member of the Chinese Nutrition Society, also spoke about gut problems at the event. He said he had been a loyal user of All-in-One Probiotics for four years: “Health depends on scientific support that can be seen and felt—repeated verification in the laboratory, real evidence used to honor our commitments to consumers, and changes that the body can genuinely feel. WONDERLAB’s commitment to evidence-based research has shown me that truth and science are the most important guarantees of health.”

WONDERLAB has consistently used R&D to drive product innovation and business development. Based on multiple population clinical studies of human gut characteristics and an end-to-end R&D and industry loop spanning basic research, strain screening, clinical validation, and industrial translation, it launched the latest version of its flagship All-in-One Probiotics 4.0 in April this year. The product continues to break new ground in strain R&D, formula design, and technology application, strengthening localized innovation and using Chinese-developed strains to support the industry’s long-term development while bringing consumers improved health-management solutions.

Six Years of Evidence-Based Research: Chinese Strain GOLDGUT-M520 Builds the Golden Gut System

Behind consumers’ real experiences and market feedback from 600 million bottles sold lies WONDERLAB’s six years of technical accumulation in the microbiome field and its commitment to evidence-based research. At the event, WONDERLAB invited Wang Xingguo, vice chairman of the Liaoning Nutrition Society and vice president of the Liaoning Nutritionists Association, to explain the four-layer intestinal barrier.

Wang Xingguo explained that the gut has four barriers forming one of the body’s most important lines of defense: the mechanical, chemical, immune, and biological barriers. When food enters the digestive system and reaches the gut, the four barriers work together to resist harmful substances. He emphasized: “Damage to any layer may lead to gut problems and trigger allergies, inflammation, or gut discomfort. Scientific gut care starts with protecting all four layers and stabilizing the gut microbiota. In addition to a balanced diet, people should specifically supplement key nutrients such as probiotics and dietary fiber.”

To address the industry’s long-standing lack of comprehensive solutions for repairing all four intestinal barriers—and the limited effectiveness of repairing only one layer—WONDERLAB, a leading Chinese probiotic company, spent five years developing its proprietary patented strain GOLDGUT-M520. It builds a Golden Gut System through “1 repair, 2 replenish, 3 accelerate.” According to WONDERLAB R&D staff, GOLDGUT-M520 was born from research spanning northern and southern China and was screened and cultivated from 453 local breast-milk samples. To verify its scientific basis and effectiveness, WONDERLAB worked with Hainan University’s tropical probiotic research team and authoritative medical institutions including Hainan Provincial People’s Hospital to conduct a randomized, double-blind clinical trial involving more than 100 volunteers.

WONDERLAB Brand Director Liu Yanchen said: “The probiotic industry previously focused on ‘microbiota regulation’ while overlooking that the essence of gut health lies in the coordinated action of four intestinal barriers. As WONDERLAB’s proprietary star strain for repairing all four barriers, GOLDGUT-M520 achieves ‘synchronous repair across four dimensions’ and offers the industry a new way to break through.”

It is also worth noting that, alongside the warm screening of the new “Tailwind” story film starring Jin Jing, Tank No. 3 at the Oil Tank Art Center simultaneously lit up real-user image stories. The scenes contained familiar minor gut troubles and reflected the relief that comes with gentle care. From stories on the screen to real sharing on the tank walls, WONDERLAB embedded its attention to gut health in every conversation with consumers.

In this dialogue between research and everyday life, WONDERLAB’s breakthrough GOLDGUT-M520 strain has injected strong momentum into China’s gut-health field. This is not only a technological breakthrough but also a positive response to the Healthy China 2030 strategy. By grounding its work in local needs, deepening evidence-based research, and advancing proprietary innovation, WONDERLAB is turning frontier microbiome research into practical health support for millions of consumers at the dining table and bringing the innovative power of local strains into the process of improving public health nationwide.
