                                An estimated one billion people globally are deficient in vitamin D, an essential nutrient for bone health. While most commercially grown mushrooms contain very little vitamin D naturally, exposing them to ultraviolet (UV) light can dramatically increase their content. This process transforms a precursor compound into a potent source of vitamin D, making it possible for you to know exactly what mushroom has a lot of vitamin D.
