Yep it's the same for me - dark when I go to work and after I finish. But I'm not taking any supplements at all so I'm just wondering if you personally notice a difference between when you do and don't take it.
Yes, I am on prescribed Vitamin D due to low results from a blood test. The difference being the dose. I do not see the sun at all for all winter. Difference is night & day (pun intended).
