Need some schooling on vitamins and supplements please?

Thanks for the responses everyone. I don’t think I’m expecting the joint pain to just be gone. Maybe it’s just part of the trade (wood flooring/carpenter) catching up with me? Maybe I did overdo it at work? Been having aches and I think this last year has really been the most noticeable. I’ll be 45 in a couple months and overall I do feel pretty good, some loss of motivation and stuff, but still believe I am in very good health. Eating better seems to be the best help and think I could do better with even just jogging in the morning before work. Hell, even just going for a walk with the dog. Again, thanks for the responses!
