Boost your glutathione levels for better performance and health with Setria® Glutathione and Setria® Performance Blend.


Glutathione is a crucial compound that’s found in all of our cells, tissues, body fl uids and organ systems. In short, it’s found virtually everywhere in the human body, and it’s essential to our healthy existence. This powerful tripeptide (a small protein molecule) consists of glutamic acid, cysteine and glycine (in the form γ-L-Glutamyl-L-cysteinylglycine), and it’s particularly benefi cial in destroying free radicals and boosting immunity. This makes it crucial for health, but also important for supporting recovery from intense training and other stressors that athletes face.

Glutathione Drives Performance, Immunity & Health

Glutathione is conditionally essential, meaning that your body can manufacture it, but not necessarily in the quantities you optimally need. Now, you can help your body boost glutathione levels by supplementing it directly with Setria® Glutathione or Setria® Performance Blend. In addition to increasing glutathione levels, the latter contains citrulline. Citrulline produces nitric oxide (NO) that is broken down in a couple of seconds. Glutathione prevents NO degradation, leading to long half-life of NO in our body. Plus, glutathione forms S-Nitrosoglutathione (GSNO), NO donor, acting as a NO slow releaser. Research demonstrates that taking a combination of Setria® Glutathione and citrulline is better for sustaining NO than taking either alone.

Here’s more about how both Setria Glutathione and Setria Performance Blend will support your health, athletic performance and training results.

Risk Factors in Glutathione Depletion

Glutathione, a nutrient-like substance that is made in the body as well as consumed through the diet, is one of the most important protective molecules in human biology. As a powerful antioxidant it neutralizes harmful free radicals and recycles vitamins E and C, the other two main dietary antioxidants. As an anticarcinogen it binds with and eliminates cancer-causing chemicals. In these roles it acts as a molecular “garbage collector,” cruising all tissues and removing unwanted toxins.

What is glutathione?

Glutathione is a nutrient-like compound that is one of the most versatile and important protective substances in the human body. It is found to varying degrees in all tissues, body fluids, and organ systems, where it plays a variety of roles in health, including:

  • elimination of cancer-causing chemicals
  • antioxidant
  • regeneration of vitamins C and E
  • support of immunity
  • maintenance of cellular proteins

The Importance of the Redox State of Glutathione

All aspects of life depend upon controlled biochemical reactions among the molecules that make up the billions of cells in the human body.  Through these reactions, chemicals share and transfer electrons to maintain the physical and chemical organization that defines life and health.  Derangements of these reactions can lead to disability and death.

The best dietary sources of glutathione might not be what you think

Many foods that are good for us – such as whole wheat bread, cereal grains, milk and yogurt – provide little or no glutathione, nor are they good sources of its precursor amino acids (cysteine, glutamate, glycine). Other foods contain reactive compounds that are antagonistic to glutathione and can destroy it before it ever leaves the spoon! Thus, compiling a glutathione-friendly diet can be a brain-tickling exercise even for professional nutritionists.
