And your statement here is part of the problem. Too many doctors are quick to look at a person and their lifestyle and just say "welp, get outside, get more active, lose some weight, get some sun" There are cases where supplements or medication are completely valid. How many (primarily women, but some men), have hypothyrodism. I know of at least 3 other women in my life who, instead of the doctor listening to their symptoms, just kept recommending "eat better, exercise more, lose weight". No. There was a serious problem. And a problem which literally makes those three things almost impossible. And can be detected with a simple blood draw. One of my friends finally went to an urgent care, they did the test, prescribed levo with a "follow up with her doctor", and the doctor wouldn't renew the prescription because she was just "inactive and retaining water". Of course at this point she switched doctors to one that wasn't a misogynist. Same thing with vitamin D. If you live above 37 degrees of latitude, chances are you are taking vitamin D most of the year because "sun on your skin" just ain't happening.
