Our Shiitake has the Most Vitamin D
- 536 IU ⇒ 9680 IU/100g
- 18x increase after UVB exposure.
The Vitamin D content in Shiitake are greatly enhanced by sunlight. Sun-dried Shiitake contain the most amount of Vitamin D of any other plant related foods. Our Shiitake are exposed by ultraviolet light in the factory so that we can further enhance and guarantee the amount of Vitamin D.
USDA has reported that the most Vitamin D rich ingredient is brown mushrooms, exposed to ultraviolet light, it has 1,110 IU/87g.
For more comprehensive data, you can refer to the: USDA National Nutrient Database for Standard ReferenceRelease 28
Our dried Shiitake will become 4x's heavier after rehydration. If we compare our Shiitake with USDA data, the following calculation can be made.
9680 IU (242µg) / 100g (dried Shiitake) ÷ 4 (rehydration factor) = 2,420 IU (61µg) / 100g rehydrated Shiitake
This equates to approximately 1,936 IU (48µg) per 80g serving of our rehydrated Shiitake.
In conclusion, our Shiitake has the most Vitamin D content of any natural foods.
