Hey…ever tried glucosamine sulfate for the knees? I had knee surgery back a few years ago and still have issues in both knees at times. When I first got on the bike this spring, a doctor friend told me about the glucosamine sulfate and I took it for a few weeks and noticed my knees weren’t bothering me as much. I ran out and stopped taking it for a few weeks and started noticing knee pain again. I have been taking it ever since. You can get it at any health food, grocery, etc. Usually in the vitamin sections…takes a couple of weeks to notice a change.
