What Is L-Ergothioneine? The Longevity Antioxidant Explained

Introduction

Antioxidants like Vitamin C and Resveratrol get plenty of attention. But there’s one overlooked amino acid antioxidant researchers are calling the “longevity vitamin”: L-Ergothioneine (EGT).

 

What Is L-Ergothioneine?

  • Amino acid antioxidant first discovered in ergot fungi.
  • Not produced in the body → must be obtained via food or supplements.
  • Transported by the OCTN1 protein → actively concentrated in brain, liver, eyes, and red blood cells.

 

How It Works in the Body

  • Protects cells from oxidative stress (neutralizes free radicals).
  • Uniquely stable antioxidant → doesn’t become pro-oxidant.
  • Preserves mitochondrial function (the “power plants” of cells).

 

Why Scientists Call It the “Longevity Vitamin”

  • Accumulates where oxidative stress is highest.
  • Potential role in preventing chronic disease and aging.

 

Where It Comes From

  • Found in mushrooms, beans, oat bran, and organ meats.
  • Supplementation offers consistent dosage.
  • Sources & Supplements

 

Conclusion

L-Ergothioneine is emerging as one of the most important nutrients for cellular defense and long-term health. -> Benefits
