Prombio Proteoglycan that I eat every day

Because of our age and the physically demanding nature of our jobs, my wife and I are consistently taking joint supplements.

There is cartilage that helps smooth the movement of joints, where bones meet, and proteoglycans are a component that accounts for 12% of the weight of articular cartilage.

Proteoglycans are extracted from the nose of salmon.

Salmon cartilage extract powder, hyaluronic acid, N-acetyl glucosamine, shark cartilage powder, and green-lipped mussel powder are all included in one tablet, so doesn't it contain everything beneficial for joints?
