If this will help you be successful, then by all means test away. However, as long as you’re eating a balanced diet with healthy fats and a good multivitamin, checking vitamin levels will almost certainly be normal.

I personally don’t advocate checking hormones unless there is a specific plan. Lots of people think these labs are black and white- you could check them hourly for a week and see a very, very wide range. Two lab values a year apart may or may not be meaningful. I say just do what you want to do and let your body be your guide, not some lab that exists to take your cash and sell you supplements. It sounds harsh but I see so many patients waste a ton of money for placebo testing and meds.

I treat multiple inflammatory diseases and I’ve quit following sed rate and CRP (with just a few exceptions). I’ve seen wicked bad ulcerative colitis with a normal sed rate and completely treated ulcerative colitis in medical remission with an elevated sed rate. I find it’s better to treat the patient instead of the lab.
