Hello F&N I'm making one of my rare visits to the forum to ask a question. I did a search on some terms I thought would be relative, but didn't find much. If it turns out the information I need can be easily located in another thread, please point me there. As I always point out, I'm a fencer. All forms of exercise and training I engage in funnel into that focus. At a competition some months ago, I managed to hit my own knee (with the grip end of my weapon) and, after seeing a sports medicine doctor (twice), was told that I likely punctured the sack of synovial fluid surrounding my knee. Ever since then, that knee has been my "weak link," that gets sore before anything else and requires extra stretching and warmup before I do any footwork, drills, or fencing. What I'd like to know is if there is some dietary supplement I can use to either improve the health of my joints (I beat the hell out of my lower body), or at least give them a longer, healthier useful life. Knee, hip, and ankle problems are common amongst aging fencers, and I want to do what I can to not become one of them. Any advice?
