Mushrooms
This source of vitamin D offers B vitamins and potassium. Vitamin D levels vary with each mushroom type, such as shiitake, portobello, moral, and chanterelle. You can also buy mushrooms that have been exposed to ultraviolet light giving them even higher vitamin D levels.
Canned tuna
It’s an easy way to get in vitamin D. Its longer shelf life makes it a great pantry staple to throw into meals as a fabulous source of protein, too. Always make sure it’s from sustainable sources and choose light tuna with the lowest amount of mercury possible.
