Follow the label here — all three softgels matter. A single softgel gives you 500mg of **Glucosamine Sulfate** and 400mg of **Chondroitin Sulfate**, which is well below the studied range for either ingredient. But at the recommended three softgels daily, you reach 1,500mg glucosamine and 1,200mg chondroitin — right at the doses used in major joint trials like GAIT and MOVES.

The glucosamine is in the sulfate form (specifically the potassium chloride salt), which carries the strongest clinical evidence for joint comfort and cartilage maintenance. **Chondroitin** is sourced from bovine cartilage, the standard source used in most research. Together, this pairing has more clinical backing than either ingredient alone.

The tradeoff is pill burden — three large softgels daily with meals. If you tend to skip doses, you'll drop below the clinical threshold quickly, since each softgels on its own delivers only about a third of the effective dose.
