There are several studies available on the use of glucosamine and chondroitin for osteoarthritis pain, although they have conflicting findings on the effectiveness of the supplements.
Glucosamine has been studied extensively for osteoarthritis pain management.
A 2018 analysis showed some improvements in knee osteoarthritis pain with regular use of glucosamine sulfate.
Additionally, a 2-year cohort study found that taking 1,500 mg of crystalline glucosamine daily reduced pain by 36% when used with a nonsteroidal anti-inflammatory drug.
According to another study, a 2-year study of 407 overweight women aged 50-60 found that taking 1,500 mg/day of glucosamine significantly reduced knee osteoarthritis pain.

After 6 months of chondroitin use the authors concluded that chondroitin sulfate may be an effective pain reliever for people with knee osteoarthritis pain.
