Glutathione-SR: A Sustained-Release, Master Antioxidant Formula

Thorne’s Glutathione-SR is an advanced supplement that provides the body’s most important antioxidant, glutathione, in a unique sustained-release formula. Glutathione is found in every cell and is crucial for liver detoxification, immune function, and protecting against oxidative stress. However, standard oral glutathione is often broken down in the stomach. Glutathione-SR utilizes a proprietary Time-Sorb® matrix that protects it from stomach acid and releases it slowly, ensuring optimal absorption and lasting benefit.*

How It Works: The Time-Sorb® Advantage

This formula is designed to overcome the common challenge of oral glutathione absorption, delivering this critical nutrient effectively to your cells.*

The Body’s Master Antioxidant
Glutathione is a tripeptide that acts as the body’s primary endogenous antioxidant. It directly neutralizes a wide range of free radicals. In addition, it plays a vital role in regenerating other antioxidants, like vitamins C and E. It is most highly concentrated in the liver, where it is essential for both Phase I and Phase II detoxification pathways.

Sustained Release for Optimal Absorption
The patented Time-Sorb® delivery system protects the reduced glutathione molecule as it passes through the stomach. It then releases it gradually in the intestinal tract. As a result, this provides a steady supply to the bloodstream over several hours. This sustained release ensures your body receives the full benefit of this powerful nutrient for protecting cells and supporting overall health.*

  • Provides glutathione, the body’s “master antioxidant”
  • Features a sustained-release formula for enhanced absorption and lasting benefit*
  • Supports the liver’s natural detoxification processes*
  • Promotes a healthy immune response and protects against cellular stress*
  • NSF Certified for Sport®, trusted for purity and safety
