Vitamin D Sun Boost

Vitamin D Sun Boost

Solar drying shiitake mushrooms (Lentinula edodes) can turn them into one of the most efficient non-animal vitamin D sources available. In this study, solar drying shiitake increased vitamin D₂ to 11.6 ± 0.7 µg/g dry weight, compared to 6.6 ± 0.7 µg/g in untreated controls, while UV-B irradiation reached 19.2 ± 0.3 µg/g. Just 1.29 g of solar-dried shiitake was enough to meet the recommended 15 µg daily intake, using sunlight alone.
