Glucosamine & Chondroitin: Foundational Support for Healthy Joints and Cartilage*

Thorne’s Glucosamine & Chondroitin is a cornerstone supplement for individuals seeking to maintain healthy joint structure and function. This formula provides the two most well-researched, fundamental building blocks for cartilage and connective tissue: glucosamine sulfate and chondroitin sulfate. Together, they provide comprehensive nutritional support to help maintain joint mobility, promote flexibility, and soothe occasional joint discomfort. It’s a trusted, foundational choice for athletes, aging individuals, and anyone looking to proactively support their joint health.*

How It Works: The Building Blocks of Your Joints

Glucosamine and chondroitin are natural components of cartilage, the resilient tissue that cushions the ends of bones within your joints. This formula works by supplying these key nutrients to support the body’s natural repair and maintenance processes.*

Nourishing Cartilage and Synovial Fluid
Glucosamine Sulfate is a crucial building block for glycosaminoglycans (GAGs), which are essential components of cartilage. It helps the body produce synovial fluid, the lubricating liquid that allows joints to move smoothly and without friction. In addition, Thorne uses the sulfate form of glucosamine, which is the form used in the vast majority of successful clinical studies.*

Providing Resilience and Cushioning
Chondroitin Sulfate is another vital structural component of cartilage. Its primary role is to provide resistance to compression, giving cartilage its essential shock-absorbing properties. It also helps to maintain a healthy balance of enzymes in the joints. By combining these two powerful nutrients, this formula provides a synergistic approach to nourishing and protecting joint cartilage from the natural wear and tear of an active life.*

  • Provides the building blocks for healthy cartilage and connective tissue
  • Supports joint mobility, flexibility, and comfort*
  • Helps maintain healthy synovial fluid for joint lubrication*
  • Features the clinically-studied sulfate forms of both nutrients*
  • NSF Certified for Sport®, trusted for purity and safety
