How to pick

Mushrooms are also known to support bone strength as they contain a good amount of calcium – a type of mineral needed to build and maintain strong bones, especially together with vitamin D.

Mushrooms are a separate kingdom classified from food and plant foods and instead known as fungi and therefore do not use photosynthesis, meaning they can grow without light and in dark environments.

But that doesn’t mean mushrooms need darkness to grow. In fact, mushrooms enhanced with vitamin D are the only plant product that provides sufficient amounts of bioavailable vitamin D if consumed in its appropriate amounts, making it a primary source of vitamin D for vegans.

When shopping for mushrooms, look for packages marked with “UVB.” If this isn’t available, you can make your own exposing them to the sun for about 10-15 minutes, which is said may provide with 100% of your daily requirement of vitamin D. When refrigerated, the exposure can be retained between 4 – 8 days.
