> Blood tests twice a year. Well no thank you. Seems like an odd stance to take if you're purposefully taking things like vitamins to try and improve health. But seriously, blood tests literally take ~15 minutes of my time, 2 times a year. I Schedule online, go in for a blood draw, and get results a few hours later online. It's minimal effort (my favorite kind of effort) and lets me know which supplements are working (Vit. D for example, is working very well) and which are pointless (i.e. as I learned most iron supplements are garbage and don't get absorbed).
