Product Details

What is Chondroitin Sulfate?

Chondroitin Sulfate is often taken with glucosamine sulfate to support joints and cartilage in the body.

Chondroitin sulfate binds to collagen and elastin in the formation of cartilage. It is a glycosaminoglycan (GAG), also known as a mucopolysaccharide, and a biological polymer derived from connective tissue that supports cartilage production.

The body becomes less effective as people age at repairing and regenerating tissues that include cartilage, which acts as a shock absorber for joints and vertebrae.

Chondroitin is present in the lining of the digestive tract, blood vessels, mucus membranes and arteries and helps promote normal blood flow throughout the body.

Chondroitin supports the integrity and resilience of cartilage.

Chondroitin sulfate is also used as an eye drop for dry eyes. In addition, it has been during cataract surgery, and in a solution for preserving corneas used for transplants.

Chondroitin sulfate B is found in the dermis of the skin and is one of the constituents that help maintain skin viscoelasticity.

Chondroitin is synthesized from natural sources of cartilage, such as those derived from sharks or cows, and synthetic sources. It is important to keep in mind that chondroitin absorption takes time.

Purity and Concentration of Chondroitin Sulfate

Purebulk's chondroitin sulfate powder is extracted from bovine trachea cartilage and is assayed by the manufacturer to contain at least 90% chondroitin sulfate. The remaining 10% is collagen material from the extraction process. There are no additives, fillers or anti-caking agents.

How should I store it?

Store in a cool, dry area protected from light. Reseal after each use.

Potential Side Effects of Chondroitin Sulfate

There have been isolated reports of nausea, upset stomach, diarrhea or constipation, indigestion, stomach pain and heartburn.

Because chondroitin is a natural anticoagulant, anyone with blood disorders or who is currently taking blood thinners or aspirin should consult a physician.

Bioavailability, Mixing and Solubility of Chondroitin Sulfate

Chondroitin can be taken with or without meals.
