What is Chondroitin Sulfate?

Chondroitin sulfate is a chemical that is normally found in cartilage around joints in the body. Chondroitin sulfate is manufactured from animal sources such as cow cartilage.

Is Chondroitin Sulfate effective?

When used with conventional anti-inflammatory medications such as ibuprofen (Advil, Motrin, etc.), 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.

Chondroitin sulfate is often sold in combination products that also contain glucosamine sulfate. So far, there is no evidence that the combination products work any better than either chondroitin sulfate or glucosamine sulfate alone. Buying a combination product is probably not worth any extra cost.

There isn't enough information to know if chondroitin sulfate is effective for other conditions people use it for, including: heart disease, osteoporosis (weak bones), or high cholesterol.

Possibly Effective for...

  • Dry eyes as an eye drop.
  • Reducing pain from a kind of arthritis called osteoarthritis.

Insufficient Evidence to Rate Effectiveness for...

  • Heart disease, osteoporosis (weak bones), high cholesterol, and other conditions.

Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
