Eat real food. Mushrooms have vitamin D, kale has vitamin K. All of these things have varying degrees of volatility, so cooking can making them more or less bioavailable, and in pill form they oxidize and have a wide range of potency. Cheap supplements almost certainly have no potency so you're just throwing your money away. Most people should just eat real food and not so much of it. (And pizza is not a real food sorry.)
