  • Except vitamin D, deficiency is very widespread
  • And iron for most women
  • And sometimes magnesium for sports (which we should all do)

    I'm D deficient. I took D supplements for a long time; m D levels never significantly increased.

    When you look at large-scale studies of OTC vitamins, you quickly realize that the absorption on most of them is very poor; they don't really move the needle very much. In most cases, you will be better off if you address vitamin and micronutrient deficiencies through diet rather than attempting supplementation.
