Why Glutamine?

Glutamine is the most abundant and versatile amino acid in the body. It can be used in almost every cell for DNA synthesis, as an antioxidant, and helps maintain cellular integrity and function. It is the most critical nutrient for immune system function.

Glutamine is routinely used for pre and post-operative patients and also to restore the immune function of elite athletes. It is considered a non-essential amino acid except in times of severe injury or illness. The cells of the immune system rely on glutamine to function, particularly during times of illness. Glutamine is the “fuel of the immune system”. Inadequate glutamine impairs immune cell function.

Benefits of Glutamine*:

  • Improved Immune System Function
  • Improved Brain Function
  • Maintenance of Blood Sugar Levels
  • Decreased Muscle Soreness and Fatigue
  • Reduces Ammonia During Exercise
  • Increased Muscle Mass
  • Preferred Fuel of Immune, Digestive, and Muscle Cells
  • Regulates pH Balance
  • Promotes Recovery from Surgery and Injury
  • Improved Digestive Health and Supports a Resilient Gut
  • Glutamine functions as an important biosynthesis precursor in intestinal cells by supporting the synthesis of Glutathione, a critically important antioxidant.

“There is increasing evidence that systemic Glutamine functions as an important biosynthesis precursor in intestinal cells by supporting synthesis of Glutathione”

A Naturally Superior Source

Glut Immune™ is a natural source of Covalent Bonded Glutamine derived from red wheat berries. It is dairy-free. The glutamine in Glut Immune™ is connected by covalent bonds to other amino acids on a multi-protein chain to ensure optimal absorption.

The Finest Glutamine Supplement Available

Glut Immune has the highest absorption and stability to deliver up to 10 times more pure glutamine to the bloodstream than supplements made with L-glutamine.

This product is 32% highly absorbable glutamine by weight. It is enzymatically derived from wheat and contains 14% gluten.

Best Glutamine Supplement

Why Use Glut Immune?

The majority of commercially available glutamine sources contain only the cheapest source of glutamine, called L-Glutamine. L-Glutamine has been shown to be unstable in the presence of heat, water, acid or base solutions, making L-Glutamine impractical to utilize for any purpose other than powdered food preparations.

The instability of L-glutamine supplements in water and pH extremes means it is safe to assume that a majority of L-Glutamine decomposes once it passes into the human gastrointestinal tract. Stomach acid has a pH less than 2 and the body a temperature of 98.6 degrees Fahrenheit, in these conditions L-Glutamine decomposes very quickly.

Covalent Bonded Glutamine, used in Glut Immune, has been shown to withstand processing temperatures of 180 degrees Fahrenheit for one hour or 250 degrees Fahrenheit for 15 minutes, as well as pH variances in the range of 3.5 to 9.0. In addition, Covalent Bonded Glutamine is stable in aqueous solutions for prolonged periods of time. Covalent Bonded Glutamine can be used in all liquid and semi-solid food preparations without degradation.

Higher Rate of Absorption

Free amino acids, such as L-glutamine, are absorbed through the intestinal wall by a different mechanism when compared to covalently bonded amino acids. The absorption mechanism of free amino acids is competitive, meaning that in an excess of free amino acids, only a small percentage of any particular free amino acid will be absorbed.

Covalent Bonded Glutamine, on the other hand, is absorbed more effectively via a less “competitive” method.  Studies by P.D. Fairclough et al., G.K. Grimble et al, and D.B.A. Silk et al, have shown that uptake of amino acids is faster and more “even” from large peptide chains in the human intestine. In other words, Covalent Bonded Glutamine will be absorbed faster and more efficiently than free L-Glutamine in the human digestive system.

Recent publications have stated that covalent bonded glutamine delivers up to 10 times more glutamine to the blood stream than L-glutamine.

Glutamine Powder Benefits for Glut Immune

Glut Immune™ is a spray-dried form of glutamine, which is stabilized to withstand changing temperature, pH, and aqueous environments. The product is a mixture of oligopeptides, protein chains made up of various amino acids. This creates a stable and nutritionally-effective product that is able to withstand exposure to high temperatures, pH variations, and resists breakdown in liquid, unlike free form L-glutamine. For this reasons, Glut Immune™ mixes best in an electric blender and may be used in combination with Vital Whey®, Bioactive Colostrum™, and ImmunoPro®.

    10 year user
    I have been using Glutimmune with great results for 10 years. I alternate days of long aerobic training with days of high intensity interval training running and biking. No other L-glutamine
    product comes close in effectiveness. I use 5 grams before exercise and 5 grams after.
    I can give this product the highest rating.
