Shark cartilage CS is predominantly chondroitin-6-sulfate (CS-C) — a distinct sulfation pattern from the CS-A found in bovine/porcine sources, offering a complementary structural profile.
Meets USP 43 monograph standard — accepted in North American, Japanese, and Asia-Pacific supplement markets.
Shark CS has a long history of use in Japanese and Korean joint health markets and remains a recognized ingredient in Asia-Pacific supplement formulations.
Specific rotation -12.0° to -19.0° — the same marine-derived analytical profile as fish CS, distinguishing it from mammalian sources.
Individual impurity ≤ 2% — confirms consistent CS structure with minimal contaminating glycosaminoglycans.
Shark-derived ingredients are subject to increasing regulatory scrutiny in some markets due to shark conservation concerns. Please verify local regulatory acceptance before specifying this source.
Shark CS maintains strong market presence in Japan, Korea, and broader Asia-Pacific markets where it has an established consumer recognition and acceptance.
For formulators seeking the distinct CS-C sulfation pattern as a product differentiation factor or to match traditional Japanese pharmacopoeia CS specifications.
Shark CS with defined CS-C content used in research comparing CS sulfation pattern effects on biological activity.
