I get regular bloodwork as my insurance gives it at zero cost, so I just refresh an old medical order that I keep adding things to after chatting with my doc on what's relevant to measure. After trying several things, some of them without much effect or probably unsafe, I've settled for these: + Vitamin D3 5000 IU/d, measurements now give me 50 ng/mL, an improvement from my baseline which is lower than the minimum (historically 15, suggested lowest range in lab is 20) Megadoses of 100.000 or 50.000 for a few days, as given by doctors previously, just spiked this with a subsequent fall that wouldn't recover no matter how much sun exposure I got, or lower dosages, maybe with the exception of 2000 IU/d which keeps it a bit lower than 50 yet acceptable + A combination multivitamin with C-500mg, B-complex & zinc 15mg + High quality Omega 3s, more EPA than DHA, a few months a year. It improves LDL/HDL profiles. A few promising ones that I may rotate in a given a year: + A combination magnesium/zinc combination pill, taken at night + Melatonin, a few weeks if I'm starting to stay up late + Glucosamine-chondroitin, seems promising long term to prevent joint issues + NAC + Creatine in capsules, less hassle than the powder + Probiotics + Stimulant pills with different caffeine forms (guarana, anhydrous...) and all the pixie dust energy drinks have, just to save money on those or when I get bored of coffee.
