Four important fat-soluble vitamins are A, D, E, and K. Vitamins A, D, and K cooperate synergistically, not only with each other but also with essential minerals like magnesium. Magnesium, calcium, vitamin D3, or vitamin K2 also work in tandem, so if youâre considering taking one, you need to take all the others into consideration as well.
