    Undenatured Collagen Type II

    Premium 44mg Formulation of World-Renowned UC-II®

    We use UC-II®, sourced from the global leader Lonza. Each daily serving is concentrated with 44mg—exceeding standard dosages—to create the "UC-MAX" premium formula, specifically engineered for maximum perceivable results.

    Target Discomfort and Improve Range of Motion

    By addressing joint discomfort and stiffness, this formula helps expand your range of motion for smoother movement. It works from the inside out to overcome obstacles to an active lifestyle, supporting a steady and comfortable stride.

    Enhance Joint Flexibility and Support Fluidity

    Delivering collagen (the primary component of cartilage) in its "undenatured" state—preserving its natural molecular structure—improves joint flexibility. It lightens the burden of everyday movements, such as climbing stairs or standing up.

    Glucosamine

    Aid Cartilage Production and Support Joint Mobility

    Replenishes glucosamine, the raw material for cartilage, to support the "cushioning" function that declines with age. It targets joints like the knees and lower back, leading to light, fluid, and effortless movement.

    Reduce Cartilage Wear and Strengthen the Joint Foundation

    Maintains joint health and inhibits the wear and tear of cartilage that causes future concerns. By providing moisture and elasticity from within, it builds a strong yet supple foundation for your joints.

    Lubrication to Sustain an Active Lifestyle

    Reduces joint friction by replenishing essential lubricating components. It provides continuous support for the "joy of movement," ensuring you never have to give up the activities you love, such as sports, travel, or daily walks.

    Proteoglycan

    Rare Salmon Nasal Cartilage Extract for Deep Hydration

    We utilize rare proteoglycan, extracted at a rate of only a few hundred grams from one ton of salmon. Its superior water-retention properties provide ample hydration to the joints, supporting smooth and supple movement.

    Powerful Internal Support for Cartilage Repair and Regeneration

    Helps maintain a healthy cartilage cycle and cares for damaged areas from within. By boosting the body's natural "power to regenerate" which fades with age, it fosters a healthy and resilient joint environment.

    Protect Joint Cartilage and Inhibit Decomposition

    Suppresses enzymes that break down cartilage, protecting vital cushion tissue. Beyond just providing moisture, it preserves existing cartilage to ensure long-term joint health for years to come.

    Methylsulfonylmethane

    Directly Address Discomfort for a Smoother Stride

    Conditioning with Superior Protective Components

    Regulates the internal environment to address signs of throbbing heaviness or discomfort. It cares for the damage accumulated through daily activities, keeping your physical condition stable regardless of seasonal or environmental changes.

    "Natural Sulfur" to Support a Light and Active Daily Life

    Supplies "sulfur," an essential element for cartilage and muscle health, to maintain flexibility. It supports a lighthearted, active lifestyle where you can fully enjoy hobbies and sports.

    Calcium

    Maintaining Bone Density

    Building the foundation for a life lived on your own terms.

    We focus on the natural changes in bone density that occur with age. By supporting long-term bone health, we empower you to build a daily foundation that lets you stay active and true to yourself, regardless of age.

    High-absorption "Porous Structure" Designed for Efficiency

    Our formula utilizes calcium with a "porous structure" featuring countless microscopic surface pores. This unique design ensures rapid integration into the body and exceptional absorption, delivering essential nutrients efficiently to where they are needed most.

    Premium Calcium, Made in Japan

    We use only high-quality calcium produced in Japan under the most stringent quality control standards. With an uncompromising commitment to high purity and safety, we deliver a quality you can trust and rely on every single day.

    Protect Your Healthy Rhythm

    Conditions your internal environment to maintain a healthy state that stands resilient against daily stress and seasonal changes. By balancing your body from within, it brings out your natural vitality.

    Maintaining "Muscle Strength" for an Active Lifestyle

    In addition to supporting fundamental bone health, it targets the muscle strength necessary for healthy aging. It empowers you to build a supple physique, allowing you to enjoy an active life with a light and steady step.
