Product Overview
- Product Name: Undenatured Type II Collagen
- Synonyms: Undenatured type II collagen, UC-II collagen, type 2 collagen
- Appearance: White to pale yellow powder
- Odor: Slight characteristic odor; no fishy smell
- Water Solubility: Practically insoluble in water
Note: Unlike Hydrolyzed Type II Collagen, Undenatured Type II Collagen retains its natural triple-helical structure through a low-temperature processing method; this structure is the basis for its joint-protective efficacy, which is mediated by the mechanism of oral immune tolerance.
What is Undenatured Type II Collagen?
- Derived primarily from chicken sternal cartilage and extracted using a low-temperature enzymatic process, Undenatured Type II Collagen is a premium, functional ingredient for joint health.
- Its uniqueness lies in the preservation of its intact triple-helical structure and active antigenic epitopes, enabling it to fundamentally alleviate joint inflammation.
- Thanks to its core advantages—specifically, its ultra-low effective dosage and ability to provide anti-inflammatory repair at the source—Undenatured Type II Collagen has become a key ingredient in dietary supplements designed for joint repair.

UC-II retains its intact triple-helical active structure and antigenic epitopes, achieving anti-inflammatory repair through immunomodulation; it is a high-efficacy functional ingredient. In contrast, hydrolyzed collagen merely provides amino acid nutrition without targeted anti-inflammatory or reparative effects, making it suitable only for basic maintenance.
Undenatured Type II collagen does not work through nutritional accumulation; instead, it regulates joint inflammation at the source via a unique mechanism of intestinal immune tolerance. The standard 40mg/day dosage is clinically validated to deliver stable, highly targeted efficacy.
It is primarily suited for high-precision, high-stability functional products such as capsules and tablets, targeting the professional joint repair market.
Undenatured Type II collagen represents only the active component within the total protein content. Total protein encompasses both the undenatured Type II collagen (which retains its triple-helical structure) and denatured collagen (where the structure has unraveled during processing). The remaining content—calculated on a dry-weight basis—consists of ash, trace amounts of fat, and naturally occurring cartilage carbohydrates.
