GNC Glucosamine Sulfate 500 Mg, 90 Capsules, Supports Healthy Joint Function

I’ve never used a different product so can’t address this one compared to another. That said, it’s magical! I take two per day and almost never have joint pain. Took under two weeks to work. I have reordered a number of times.

I've had osteoarthritis in my knees for decades, and tried many glucosamine/chondroitin brands and combos. Since taking this particular brand, GNC glucosamine 1000mg a day for 2 months, I can do anything without pain. Biking, hiking, stairmaster, lifting weights. I don't know why it should be different than other glucosamine brands but it sure works for me.

Didn't work for me.

helps my knees but irritates my ulcers. what a pity! one capsule doesn't help. one capsule 3 times a day helps somewhat

Plugs you up!
