Product Description

Chondroitin Sulfate is a naturally occurring glycosaminoglycan (GAG) derived from animal cartilage sources, including bovine, porcine, and marine (shark) cartilage. It is a high-purity, standardized ingredient widely used in joint health formulations. Our Chondroitin Sulfate is produced through controlled extraction and purification processes, yielding a white to off-white powder with consistent molecular weight and sulfation patterns.

As a key structural component of cartilage tissue, Chondroitin Sulfate is valued by formulators for its ability to support joint comfort and mobility in dietary supplement applications. It is available in multiple grades to meet diverse formulation and market requirements.

Key Nutritional & Chemical Profile

Chondroitin Sulfate is a versatile ingredient for joint health and connective tissue support formulations. Below are its key properties from a formulator‘s perspective:

Joint Health Support: Used as a core ingredient in dietary supplements targeting joint comfort, mobility, and cartilage health. Often combined with glucosamine, MSM, or hyaluronic acid for synergistic formulations.

Cartilage Structure Maintenance: As a natural component of cartilage extracellular matrix, it supports the structural integrity of joint tissues in supplement applications.

High Water Retention: Its hygroscopic nature helps maintain hydration in connective tissues, contributing to joint lubrication and comfort.

Formulation Versatility: Compatible with capsules, tablets, powder blends, and functional beverages. Available in multiple molecular weights and sulfation grades to match specific formulation needs.

Standardized Quality: Each batch is standardized for consistent chondroitin sulfate content, ensuring reliable performance in finished products.

Recommended Usage

  • Dietary Supplements: 200 – 1,200 mg per serving, depending on formulation and target population.
  • Functional Foods: 50 – 500 mg per serving.
  • Combination Products: Commonly paired with Glucosamine (500 – 1,500 mg) and MSM (500 – 2,000 mg) for joint health formulas.

Storage

Storage Conditions: Keep in a sealed, cool, dry place away from direct sunlight, high humidity and peculiar smell. Sealed refrigeration is strongly recommended after opening to avoid moisture agglomeration and maintain original chemical activity.
