Key Benefits
Longevity Antioxidant
Highest ergothioneine of any Oyster species — transported into human mitochondria via dedicated OCTN1 transporter
Cognitive Defense
Low plasma ergothioneine linked to Parkinson's and MCI; 50% lower cognitive impairment odds with weekly consumption (2020 RCT)
Cholesterol Control
Mevinolin (natural lovastatin analog) reduces LDL through the same mechanism as pharmaceutical statins
Immune Support
Beta-glucan polysaccharides and B-vitamin complex support immune function and cellular energy metabolism
Already colonized with Pleurotus citrinopileatus, selected for vivid golden-yellow color and tight, ruffled cluster formation. Cut it open, mist it, and expect pins within a week — Golden Oyster is one of the fastest fruiters in our lineup.
Supplemented hardwood sawdust, autoclave-sterilized and colonized in our lab under HEPA-filtered positive pressure. Fruit at 64–77°F with 85–90% humidity and strong fresh air exchange — CO2 buildup causes long stems and small caps instead of the tight golden clusters this species is known for.
Expect 3 flushes at roughly 20% biological efficiency over 4–6 weeks.
