Glucosamine is a natural substance present in shellfish, and it’s commonly sold as a joint health supplement.

Research has shown that glucosamine can help reduce the rate of collagen degeneration and the symptoms of osteoarthritis. Studies have also shown that it can protect cartilege in healthy athletes as well (one study was done with cyclists, and another with soccer players).

If you’re regularly engaging in activities that wear down cartilage like weightlifting or cardiovascular exercise, then I recommend taking this product to help protect your joints.

(Oh and in case you’re wondering, chondroitin is a substance found in cartilage that is also often sold as a supplement for joint health. Research is conflicting on whether it works or not, though.)

How to Take

The dosage most commonly seen for alleviating symptoms of arthritis is 1.5 grams per day. The studies conducted with athletes used 3 grams per day, but it appears that 1.5 grams per day is equally effective.
