Chondroitin sulfate is a natural component of cartilage. It is extracted from shark or bovine cartilage, and can also be synthesized artificially. It is often combined with glucosamine. Stanford Chemicals Company is a professional manufacturer and supplier of chondroitin sulfate powder in the USA. We provide pharmaceutical-grade and food-grade chondroitin sulfate powder. Our products can be used in eye drops and injectable formulations, especially suitable for treating osteoarthritis.
Chondroitin sulfate is widely distributed in the extracellular matrix and on the surfaces of animal cells. It is a key component of hyaline cartilage, which is the tissue that cushions joints. Therefore, chondroitin sulfate is commonly used to relieve joint pain. People often take chondroitin sulfate together with glucosamine, another structural component of cartilage.
Besides treating osteoarthritis, chondroitin sulfate is also a very common and important ingredient in eye drops. It is usually combined with sodium hyaluronate and electrolytes. This combination forms compound eye drop solutions.

Chondroitin sulfate is generally safe to use. The most common side effects may include stomach discomfort, like nausea, bloating, or diarrhea. In such cases, it is recommended to take it in divided doses to help reduce the reactions. Pregnant and breastfeeding women should avoid using it because its safety for these groups is not yet confirmed.

When used with conventional anti-inflammatory medications, chondroitin sulfate seems to help reduce hip and knee joint pain due to a type of arthritis known as osteoarthritis. It can take up to 4 months of treatment for relief of pain.
In osteoarthritis, the cartilage in the joints breaks down. Taking chondroitin sulfate, one of the building blocks of cartilage, might slow this breakdown.
