Vitamins and Minerals

Vitamin D

Vitamin D is essential for bone health and maintaining healthy energy levels. Shiitake mushrooms by themselves, without any extra exposure to direct sunlight, contain small amounts of Vitamin D.

You can naturally multiply a shiitake mushroom’s Vitamin D levels by exposing them to sunlight. Evenly slice organic mushrooms on a tray and place them outside in direct sunlight from 10 am to 4 pm.

The most vitamin D has been found in shiitakes that have been dried outside for at least six hours each day for two days in a row.

There is a difference between dried and sun-dried shiitake benefits. While mushrooms dried in a dehydrator will experience some level of increase in vitamin D, they will have nowhere near the amount of Vitamin D that sun-dried mushrooms contain.

Sunned shiitake mushrooms can provide you with a full recommended daily dose of Vitamin D (600-800 IU, depending on your age) and are recommended for people suffering from Vitamin D deficiency. Adults over 65 are most prone to Vitamin D deficits due to not getting enough sunlight.
