Vitamin A and D

Vitamin A and D are used in immune function due to their assistance with cell function and their role in treating inflammation. Vitamin A is found in cheese, oily fish, or a diet high in beta-carotenes. This includes yellow, red or green vegetables, or yellow fruits such as mango. Vitamin D is found in most foods sourced from animals such as milk, meat and eggs, however most vegan or vegetarian substitutes such as tofu or plant-milk are also fortified with vitamin D. Putting your mushrooms on a sunny window ledge also helps increase their vitamin D content.
