Effect of Consumption of Post-harvest UV-B Treated Mushrooms on Vitamin D Status of Healthy Adults

NCT01443897 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 48

No results posted yet for this study

Summary

This study will investigate whether mushrooms treated with ultraviolet (UV) light to increase their vitamin D2 content are actually a good source of vitamin D when consumed daily with a meal (lunch). The mushrooms will be provided cooked along with a meal which will be a standard, pre-packaged frozen meal. We also hope to learn if the resulting improvement in vitamin D status affects the immune system by decreasing it's level of activation, which may be abnormally elevated in vitamin D deficiency.
