Years of abuse and getting older, have taken a toll on my knees. I've started taking Glucosamine Sulfate supplemments at the recommendation of a good friend.

I've heard other's swear by it also, but it's my understanding that it can take 3 to 4 weeks for the effects to be felt, or in my case, soreness in the knees.

Just wondering if any others here might take these, and have experienced any benefit from it, or is it all just snake oil?

Thanks ahead for any help,
J.
