What is the raw material of chondroitin?

Chondroitin, fully known as chondroitin sulfate, is a polysaccharide naturally found in the connective tissues of humans and animals. The chondroitin commonly seen in dietary supplements or pharmaceuticals is primarily derived from animal cartilage. The main sources include:

Animal Sources

1. Shark Cartilage: Particularly from shark fins and skulls, which have a very high chondroitin content. This is one of the earliest and most common sources.
2. Bovine Cartilage: Typically sourced from the trachea and nasal cartilage of cattle.
3. Poultry Cartilage: Mainly obtained from the breastbone and trachea of chickens.

Among these sources, shark and bovine cartilage are the two most prevalent types on the market.

In response to considerations such as sustainability, veganism, or religious factors, vegan chondroitin has emerged as an alternative:

Vegan Alternatives

1. Microbial Fermentation: This method utilizes genetically modified microorganisms (such as E. coli) to produce chondroitin in fermentation tanks. It is an emerging and more sustainable approach, though it is not yet mainstream.
2. Plant-Based Sources: Extracted from marine algae, this form mimics the structure of shark-derived chondroitin. With a daily dosage of only 200–400 mg, it is celebrated for its natural origin and eco-friendly safety. A representative product is Plondroitin™.
