Fni® Citrine Pleurotus Extract
Pleurotus citrinopileatus Singer – Natural Ergothioneine 1% (HPLC)
Product Overview
Fni® Citrine Pleurotus Extract is a concentrated mushroom ingredient produced from Pleurotus citrinopileatus Singer, also known as Golden Oyster Mushroom or Citrine Pleurotus.
This rare edible mushroom is naturally rich in ergothioneine, a powerful intracellular antioxidant known for its role in cellular protection, mitochondrial support and healthy aging.
Standardized to 1% natural ergothioneine (HPLC), this extract provides a stable, bioavailable and clean-label source of one of nature’s most important cytoprotective molecules.
Botanical Information
-
Latin name: Pleurotus citrinopileatus Singer
-
Common name: Golden Oyster Mushroom, Citrine Pleurotus
-
Part used: Fruiting body
Citrine Pleurotus grows naturally in subtropical and temperate forest ecosystems, where it accumulates protective thiol-based antioxidants to defend against oxidative and environmental stress.
What Is Ergothioneine?
Ergothioneine (ET) is a unique sulfur-containing amino acid found almost exclusively in mushrooms.
It is actively transported into human cells by the OCTN1 transporter, meaning the body is biologically designed to absorb, retain and use ergothioneine for cellular defense.
Ergothioneine is considered a “longevity antioxidant” because it:
-
Accumulates in mitochondria
-
Protects DNA and proteins
-
Shields cells from oxidative and inflammatory damage
-
Supports immune and nervous system health
Core Functional Benefits
Cellular & Mitochondrial Protection
Ergothioneine protects mitochondria — the cell’s energy centers — from oxidative stress, helping maintain energy production, endurance and cellular longevity.
Anti-Aging & Longevity Support
By reducing cumulative oxidative damage, ergothioneine supports healthy aging, skin integrity and tissue regeneration.
Neuroprotection
Ergothioneine crosses the blood–brain barrier, protecting neurons from oxidative injury and supporting cognitive and nervous system health.
Immune & Inflammatory Balance
Supports immune resilience by modulating inflammatory responses and protecting immune cells from oxidative overload.
Metabolic & Organ Protection
Ergothioneine accumulates in organs with high oxidative load, including liver, kidneys, eyes and cardiovascular tissues, where it provides targeted protection.
