Milky mushrooms are a rich source of protein and vitamins B2 (riboflavin), E and A as well as phosphorus, potassium and selenium.
The mushrooms also contain calcium, iron and zinc.
Milky mushrooms are rich in ergothioneine, an antioxidant that helps protect the body’s major organs from oxidization and free radicals.
Milky mushrooms are also a good source of another antioxidant, vitamin C, and contain more of the vitamin than oyster mushrooms.

Oyster mushrooms are a popular type of mushroom linked to several health benefits.
In addition to being highly nutritious, they may promote heart and immune system health, encourage healthy blood sugar control, and provide antioxidant and anti-inflammatory effects.
Beyond the basics, oyster mushrooms also have decent nutritional value thanks to their wide range of vitamins, minerals, and antioxidants.
Niacin: Almost every cell in the human body requires niacin to function and metabolize other nutrients.
Vitamin D: Vitamin D is not easy to find in food products (it typically comes from sunlight). However, mushrooms treated with UV lights are one of the best food sources of vitamin D.
Iron: Red blood cells require iron. One cup of oyster mushrooms gives you 12% of your recommended iron intake which makes them a great meat substitute in that respect.
