Qサイ refreshes packaging for its Healthcare Series with designs depicting a bright future of "Well-Aging."

Qサイ Co., Ltd. (Headquarters: Chuo-ku, Fukuoka; President and CEO: Junro Ishikawa) will sequentially refresh the package designs for its Healthcare Series starting from July 2026, with the aim of more clearly communicating its message as the "No. 1 Well-Aging Company." The new packaging will feature illustrations that evoke a "bright future" beyond daily health habits, evolving into an easy-to-understand design that facilitates intuitive selection. Qサイ will continue to support everyone's healthy and "well-aging" daily lives. As a first step, starting in July, we will begin transitioning products such as "N-Acetylglucosamine Z" and "Glucosamine Collagen Premium," and simultaneously launch the new product "DHA & EPA" with unified packaging.

Qサイ's "Well-Aging" and "Human Diamond" Concepts

Qサイ's concept of "Well-Aging" is to "positively embrace aging and live a fulfilling life." To achieve this, it is essential to maintain both physical health and a vibrant, satisfied state of mind. Our company strives to realize a well-aging society where each customer can embark on new "first-time" experiences at any age.

To enable this way of life, Qサイ believes that it is important to harmonize the body's "homeostatic balance" rather than just focusing on isolated areas of health. We have named this balance "Human Diamond." Human Diamond is Qサイ's unique healthcare concept, where multiple bodily elements such as the musculoskeletal system, brain, sensory organs, immune system, and circulatory system work in連携 (renkei - cooperation) to maintain overall health. We understand the age-related changes in each customer's body and propose optimal improvement plans.

Design Innovations and Consistency for Intuitive Product Selection

This package design refresh is a crucial initiative to visually communicate the philosophy of "Well-Aging" and the product group based on "Human Diamond." The new design expresses not only the functional benefits of the products but also the "bright future" that can be achieved through them, strengthening the message as the "No. 1 Well-Aging Company." The design has been refined to allow customers to intuitively select supplements that match their health concerns from Qサイ's wide range of products based on the Human Diamond concept.

1. Package Design Consistency

The top of the package features the product's tagline and design illustration. A "Well-Aging Line," a wavy line symbolizing well-aging, is drawn in the center to create a sense of unity across the entire series. The product name and dosage form image are placed at the bottom, with efforts made to make the contents easy to understand.

This unified design structure will be used to develop a product lineup that supports well-aging.

2. Use of Easy-to-Understand Illustrations Depicting a "Bright Future"

The ingredients and expected effects of each product are expressed through illustrations as images of a well-aging lifestyle. This allows for a more intuitive understanding of the ingredients and functional claims.
