“inflammation is now understood to be a key mediator of OA that contributes to cartilage loss and progressive degeneration of affected joints… OA is no longer considered a noninflammatory arthritis or a ‘wear and tear’ disease”
I heretofore thought age-related cartilage loss was the cause of osteoarthritis and inflammation. Turns out it’s the other way around: the inflammation degrades cartilage. Okay, no more slogging through joint pains for me, regardless of how small.
Edit: added a phrase for clarity
It helps your body strengthen your T cells which are the regulatory captains of your immune system. I have an auto-immune disease and doctors are always commenting on how good my wife and kids vitamin D levels are. I insist they take a good daily dose. Vitamin D is also pretty difficult to overdose on over the counter. You have to take an unreasonable amount of pills to cause any harm even if you buy the higher dose pills. Its not like other vitamins, it’s more like a hormone to your body.
Plus it recently came out that the recommended daily values of vitamin D were based on a typo and are off by a factor of at least 10 (source).
