Let’s say I’m vegan and I need to take vitamin B12 supplements to be healthy. Furthermore, let’s say I have ADHD, I forgot to take them for a month, I feel like shit, and while I know to take them now, there’s no guarantee I’ll remember tomorrow.
If I were to take 2 tablets today, an amount which I surely need, would my body actually absorb all the B12 it needs, or would I piss out the second tablet? Do I have to wait until tomorrow to absorb the nutrients my body needs now?
You need a doctor’s for the exact figures. Just saying “a pill” without dose is btw completely irrelevant.
And yes, you’ll pee most of it out what you can’t absorb.
Something to check for is vitamin K (not sure about your local naming scheme though y shot seems to suffer internationally). You’re body needs that stuff to absorb the B. I actually have a K production problem, that’s why I was B deficient.
Doctor prescribed 10k I.E. B with fitting K - daily! That’s a crazy amount that would be absolutely useless without my specific circumstances.
And one more thing: ADHD or not you need to find your way to remember medicine. D just kills your mood, blood pressure in a few years might just kill you.
My approach for example is a the tier alarm system, mix of voice assistant, a daily mail and push notifications. Plus I have my medicine both at home and at work.
