Oyster mushroom
Also known as: Pleurotus ostreatus
Oyster mushroom is a common edible mushroom rich in beta-glucans (pleuran), fibre and ergothioneine. It also naturally contains small amounts of lovastatin, so it is studied for effects on cholesterol.
What it is used for
- immune support and fewer respiratory infections – weak to moderate evidence from smaller studies with pleuran extract
- cholesterol support – weak evidence
- antioxidant effect – weak evidence
Forms and how they differ
beta-glucan extract (pleuran)
best-studied form; check beta-glucan content on the label
fruiting body powder
food form with lower active content
fresh or dried mushroom
an excellent food, always cooked
Pairs well with
Vitamin C, vitamin D, zinc.
Do not combine / separate

Watch out for
