I am curious, what does it take to innovate in vitamin level testing space? Being able to know vitamin level in your body at any given day just like you can measure your heart rate. Not via mailing in blood sample, but something simpler. is it too far fetched to think that we can have something like a watch to be able to measure our vitamin levels regularly?

I'd picture something like a finger-prick blood sampler akin to a glucose meter.

Might not be something I'd do every day forever, but I could see doing daily samples for a week to get a feel for aboroption, then occasionally to check how my supplements and sun exposure are working.

If you could build a thing that can measure several different parameters depending on which test strips you load into it, I'd buy a pack of vitamin D strips, a pack of vitamin B, a pack of testosterone, and pack that looks for markers of inflammation. Heck yeah. My doctor would eat that data right up.
