Oyster mushrooms are not only delicious, but also provide the human body with many nutrients and minerals. They are rich in proteins, amino acids – which help to enhance memory and mental development – iron, niacin – which helps to maintain a healthy heart and lower cholesterol – fiber, B Vitamins and Vitamin D.

Lots of us are lacking in Vitamin D due to many hours indoors with no sun exposure, so these are a great way to boost your levels! Vitamin D positively influences cell growth and enzymes in our immune systems and our bodies also cannot absorb an important mineral, calcium, without a source of Vitamin D.

Many believe Oyster mushrooms to be the easiest to cultivate. They are primary saprophytes, which means they do not require a composted substrate. They will flourish on dead wood, straw, grass, wheat, rye, rice, corn, bamboo, cotton, hemp, coffee waste… practically any dried cellulosic plant material!
