Chondroitin

Last Updated: September 9, 2023

Chondroitin is a naturally occurring glycosaminoglycan that is present in cartilage. It is frequently taken with glucosamine to help with joint pain and other symptoms of osteoarthritis.[2]

Chondroitin is most often used for

What is chondroitin?

Chondroitin is a glycosaminoglycan made up of long polysaccharide chains with a repeating disaccharide structure and is commonly taken as chondroitin sulfate supplements. It occurs naturally in cartilage, where it helps prevent tissue breakdown and supports joint mechanics.

What are chondroitin’s main benefits?

Chondroitin is primarily used to alleviate osteoarthritis symptoms by potentially helping with pain and joint stiffness, though research on its effectiveness is mixed. Additionally, it may offer anti-aging benefits, lower cardiovascular disease risk, and assist with bladder conditions, and it has been associated with a reduced risk of certain cancers, but further studies are needed to confirm these effects.

What are chondroitin’s main drawbacks?

Chondroitin is generally considered safe and has very few side effects at the recommended dosages, but it may occasionally cause mild gastrointestinal issues like nausea or abdominal cramps.

How does chondroitin work?

Chondroitin works by drawing water into the cells for hydration and mechanical support in joints while also promoting the efficient regeneration of chondrocytes and slowing their cell death. Additionally, it has anti-inflammatory effects that inhibit proinflammatory immune factors, which may benefit arthritis and age-related diseases.

What are other names for Chondroitin?
Note that Chondroitin is also known as:
  • Condrosulf (Brand Name)
  • Chondroitin sulfate
Dosage information

Dosage recommendations range from 800 mg–1200 mg per day. This may be taken as a single dose or in 2–3 400mg doses.[1]

Chondroitin is sometimes grouped with other medications like glucosamine and referred to as a SYSDOA — a symptomatic slow-acting drug for osteoarthritis.
