Oyster Mushroom

(Pleurotus ostreatus)

What Is Pleurotus?

Pleurotus ostreatus (or Oyster mushroom) is a medicinal mushroom of scientific interest for its polysaccharide composition, but also for its significant content of other bioactive substances such as dietary fibre, enzymes, phenolic compounds and more. This species is one of the most marketed and consumed in cooking along with Shiitake. It is also known as ‘Oyster mushroom’,‘Orellana’, ‘Belarri landu’ or ‘Píng Gū’.

Powerful benefits of Pleurotus

Excellent source of dietary fibre

Studies have explored its effects on the immune system and as a prebiotic. It also contains high quality proteins, minerals and vitamins (especially B group), amino acids, fatty acids, and more.

Immune System

Integrative Support


Powerful nutrients in Pleurotus

LikePleurotus eryngii (King oyster mushroom), the oyster mushroom contains protein, polysaccharides, unsaturated fatty acids, vitamins and other nutrients, and is low in fat, making it a high-quality food. Its micronutrients include:

  • Beta-glucans, known to support the immune system.  
  • Peptides, Ostreolysin, laccase, lectin and other peptides and fatty acids.
  • Vitamins, B & D group.
  • Minerals, Rich in zinc.
