Summary of King Oyster

Primary information, health benefits, side effects, usage, and other important details

King Oyster mushrooms are a species of the Pleurotus family of mushrooms, and related to regular Oyster mushrooms. They have a large stem that confers a relatively 'meaty' or 'hearty' flavor (Umami) and are seen as a medicinal mushroom.

Not too many studies are conducted on King Oyster mushrooms, but they appear to have the same properties of regular bioactive mushrooms in the sense that they interact with the immune system and may 'boost' immunity to sickness. King Oysters seem to be more potent at suppressing fatty acid absorption relative to other mushrooms according to one study, and have been implicated in increasing testosterone 5-fold. This latter study was conducted with very high doses (15-20% of feed) and was conducted in elk (out of all research animals, elk) and has not been replicated.

It also appears to be more estrogenic and bone protective in animal forms of menopause than other medicinal mushrooms tested.

How to Take

Medical Disclaimer

Recommended dosage, active amounts, other details

At this moment in time, all that can be recommended is to consume the fruiting body or stem of the King Oyster mushroom in your diet if you want the effects. Supplementation would work fine (and if we take motifs from other Bioactive Mushrooms would be around 1-3g daily) but minimal human studies have been conducted.
