Abstract: A composition and methods of use are disclosed for prevention and control of inflammation and oxidative stress and various associated medical conditions, including PTSD, chronic depression and traumatic brain injury. A composition providing a phytonutrient and enriched mushrooms having enhanced Vitamin D and ergothioneine are disclosed. The combined use of an enriched mushroom and phytonutrient provide a synergistic effect on cellular longevity and/or cellular rejuvenation of subjects with both a normal and nutritionally deficient diets, improved tolerance to oxidative and/or inflammatory stress, and increased cellular longevity and/or cellular rejuvenation as a result of the neutralization of free radicals and prevention of chronic inflammation.

Abstract: An filamentous fungi is disclosed with a naturally vitamin D enriched nutritional profile. These enriched mushrooms were shown to have a synergistic effect on longevity of subjects with both a normal and nutritionally deficient diets, improved tolerance to oxidative stress, and increased longevity in a Alzheimer's disease model. Surprisingly, vitamin D2 and D3 fed alone or in combination with nonenriched mushrooms did not produce similar effects.
