Lately, everyone I talk to in the supplement space is asking the same question: *“Do you have high-purity Ergothioneine?”* And when I say yes—**up to 98% purity**, derived from **Golden Oyster Mushrooms (Pleurotus citrinopileatus)**—the reaction is always the same: “Wait, seriously?!”
Yes. Seriously. And here’s why that matters.
**What is Ergothioneine and why is high-purity so important?**
Ergothioneine is a naturally occurring amino acid and antioxidant that our bodies *can’t* produce but seem to value highly. It accumulates in tissues exposed to oxidative stress—like the brain, eyes, liver, and skin—and plays a protective role at the cellular level. While many products on the market use low-potency mushroom extracts (typically 0.1%–2%), our proprietary extraction technology delivers **98% pure Ergothioneine**, offering a precise, high-impact solution for advanced formulations in anti-aging, brain health, and skin wellness.

If you’re formulating high-end products, purity isn’t optional—it’s essential.
## Why Golden Oyster mushrooms are the best source?
Golden Oyster mushrooms are not only beautiful and rich in nutrients—they’re one of nature’s most concentrated sources of Ergothioneine. Unlike synthetic or yeast-derived options, our mushrooms are **organically grown and food-grade safe**.
Golden Oyster mushrooms provide a natural, food-grade source of Ergothioneine. Compared to synthetic or low-grade extracts, our organically grown mushrooms yield a clean, bioavailable source—ideal for premium wellness formulations.

We grow our **Pleurotus citrinopileatus** in controlled environments, using no pesticides or synthetic enhancers. After harvest, we apply **low-temperature water extraction**, followed by **ultrafiltration and column purification** to isolate Ergothioneine to **98% purity**. This process preserves molecular integrity and removes impurities—resulting in a pharmaceutical-grade ingredient.
Here’s a comparison of Ergothioneine sources:
| Source Type | Typical Purity (%) | Notes |
|————————–|——————–|——————————–|
| Button Mushroom Extract | 0.1–0.2% | Low yield, not standardized |
| Shiitake Extract | ~0.1% | Traditional source |
| Golden Oyster Raw | 0.5–0.8% | High among natural sources |
| Yeast Fermentation | ~5% | Synthetic, may need further purification |
| **Our Extract** | **98%** | Food-grade, high purity, clean-label |
## What are the benefits of 98% pure Ergothioneine?
You’ve heard of antioxidants—but few can match Ergothioneine. And when it’s this pure, the benefits are amplified.
98% pure Ergothioneine supports anti-aging, cognitive longevity, immune health, and mitochondrial protection. Its high bioavailability and long half-life make it ideal for premium supplements targeting oxidative stress and inflammation.
