Health Benefits of Oyster Mushrooms

There are centuries of historical references to oyster mushrooms to treat ailments and for other medicinal and health benefits. There is also a lot of data to support these health benefits of oyster mushrooms:

Loaded with nutrients: The list of nutrients in oyster mushrooms is long, but to focus on the most beneficial, they include:

  • Vitamin D
  • Selenium
  • Protein
  • Fiber
  • Niacin
  • Pantothenic Acid
  • Phosphorus
  • Potassium
  • Iron
  • Zinc


Protect you from cellular damage with antioxidantsTwo different studies on rodents found that in one an extract of oyster mushrooms raised antioxidant levels and reduced inflammation. In the other study, an extract improved antioxidant levels and reduced liver damage. A 2016 test tube study tested an extract of the gray oyster mushroom reduced oxidative damage to human cells and prevented oxidation of bad cholesterol. This is important because the oxidation of bad cholesterol has been found to be part of the process of atherosclerosis.

May help in blood sugar regulation: One study of people with and without type 2 diabetes found that powdered oyster mushroom reduced blood sugar levels after meals. When the study was stopped for a week, participant after-meal blood sugar levels increased significantly. That study and another of men with type 2 diabetes found that oyster mushroom reduced blood pressure as well. A later study found that the beta glucan fiber content may be the reason for the reduction of blood sugar levels.

Beneficial for heart health: P. ostreatus and its beta glucans fibers may promote heart health by reducing blood pressure and high cholesterol. While you may like those white button mushrooms at the supermarket, oyster mushrooms can provide double the beta glucans. A 2011 trial found that eating a soup with dried oyster mushrooms resulted in the conclusion: “Consumption of oyster mushrooms lowers concentrations of triglycerides, cholesterol and oxidized LDL.” There are criticisms that some of these studies may have been biased.

Immune system benefits

  • Pleuran is a type of beta glucan fiber that has been found to benefit the immune system in several ways. Some studies and trials have yielded these reports:
  • Children with chronic respiratory tract infections found their conditions improved with treatment with pleuran. Athletes also experienced upper respiratory tract infections improvement with pleuran treatment.
  • A study with 90 participants with HSV-1 improved symptoms and reduced duration of respiratory duress when treated with a combination of pleuran, Vitamin C, and zinc.
  • Another study with 41 participants found that a daily oyster mushroom supplement improved the immune system.
