Vitamin D is a steering hormone that controls the expression over a thousand different genes in your body.

Mushroom also has an ability to make vitamin D upon UV Radiation exposure and mushroom has been out in the sun and a great source of vitamin D.

There are few factors that affect our ability to produce and use vitamin D:

  1. Sunscreen: Sunscreen blocks UV Radiation
  1. Skin Pigmentation: Melanin is a natural sunscreen
  1. Age: As we age, our body became less efficient in producing vitamin D. A 70 year old produces four times less than 20 year olds.
  1. Body Fat: Body fat affects the ability to use vitamin D by reducing bioavalability of Vitamin D that is fat soluble. The more of the vitamin D store in fat, the less it is being released in your blood stream.
