Three new products from "Yu Yan Sang" will be released sequentially.

Background of the release

In today's world, where stress and irregular lifestyles are commonplace, there is growing interest in "preventive medicine," which involves maintaining good health through daily diet and lifestyle choices rather than dealing with symptoms after they appear. Our company, which was founded as a gastrointestinal medicine company, has long been attentive to the health of consumers in the oral medication field. In recent years, as a "pharmaceutical company that doesn't rely on drugs," we have been working on "food" as one of the options to support daily well-being, in addition to addressing symptoms after they appear.
In East Asia, there is a tradition of "dietary therapy" that involves incorporating ingredients and traditional materials into daily life to maintain overall physical balance and condition. Through the Yu Yan Sheng brand, which has delivered this wisdom, our company proposes the concept of "nurturing Vital Origin" in a way that suits Japanese lifestyles. "Nurturing Vital Origin" is the idea of drawing on the life-sustaining power of ingredients to support the inherent strength of the human body. Rather than supplementing only specific components, we value delivering the wisdom of traditional ingredients in a form that is easy to incorporate into daily life.
In the Japanese market, our first product, "Yu Ren Sheng Cordyceps," launched in March of this year, has been well-received as a first step in self-care habits for those aiming for a healthy daily life (limited release from January). With this second release, we are launching "Yu Ren Sheng Chicken Soup," "Yu Ren Sheng Reishi Mushroom," and "Yu Ren Sheng Bird's Nest," a lineup designed to make the concept of dietary health more accessible. By expanding the concept of dietary health through a range of products with different ingredients and methods of use, we offer new options for addressing daily health and well-being.

Focus on materials

• Chicken Essence

  Nutrients extracted from chicken itself have long been recognized overseas as being extremely beneficial to health. It's widely used by people of all ages, from young children to seniors, when they're concerned about nutrition or want to maintain their energy levels. It's characterized by its highly concentrated nutrients and low fat content.

• Reishi mushroom

  This type of mushroom has long been used in China as a nourishing ingredient. It is valued for its ability to protect the body from various environmental changes, and the spore portion in particular is considered even more precious because it can only be harvested for a short period.

• swallow's nest

  It has long been prized as a beauty and nourishing food ingredient. It is a rare ingredient containing glycoproteins and sialic acid. Sialic acid is a component found in large quantities in breast milk, especially colostrum.

Product features

• Yuinsheng Chicken Soup

  

  Made using only chicken, with no added water, salt, or other seasonings. The extraction process begins within 30 minutes of slaughter, and the essence is concentrated into each bag through a slow, high-pressure extraction over 8 hours. In Taiwan, it is a traditional nourishing food popular as a gift for students taking exams or for new mothers.

• Yu Ren-sheng Reishi

  

  This product uses Reishi mushroom, a traditional ingredient. Each capsule contains 240mg of Reishi broken spore powder and 60mg of Reishi extract powder. The cell walls of the spores are hard, making it difficult to extract the nutrients inside, but Yu Ren Sheng processes the spores to break down the cell walls and also uses special methods to deliver the nutrients.

• Yu Ren Sheng, Swallow's Nest

  

  Made with bird's nest from Malaysia. The only ingredients used are water, bird's nest, and rock sugar.

Future developments

Going forward, our company will deliver the wisdom of dietary health cultivated by Yu Yan-sheng to Japanese consumers in an easy-to-understand way, not only through products but also through methods of incorporating them into their lives and the philosophy behind health maintenance. We also aim for the culture of "giving the gift of health," which Yu Yan-sheng cherished, to spread naturally in Japan through our products, information dissemination, and various proposals, as the daily habit of taking care of one's own health eventually leads to actions of caring for those close to you.
Moving forward, we will continue to work towards realizing well-being in the coming era by combining the wisdom of Yu Ren Sheng's traditional materials with the scientific knowledge and consumer-centric perspective that our company has cultivated.
