1. Supports Digestive Health: Glutagenics 167g Powder by Nutri Advanced contains a unique blend of ingredients that support the health of the digestive system. It contains glutamine, which is an important amino acid for maintaining the integrity of the intestinal lining, and licorice root, which has anti-inflammatory properties that can soothe digestive discomfort.
2. Promotes a Healthy Immune System: This product also contains a special form of zinc called zinc carnosine, which has been shown to enhance the immune response and support healthy gut function. This can help to protect against infections and keep the immune system strong. Additionally, the presence of aloe vera in this formula can help to reduce inflammation and support immune function.

The active ingredient is: L-glutamine

L-glutamine is the most plentiful nonessential amino acid in the body and acts as a vital fuel and growth precursor for fast-dividing cells of the gut lining.

This blend uses the Sustamine dipeptide structure, which joins L-glutamine with L-alanine to boost stability and uptake, supporting gut barrier health.

What L-glutamine does?

L-glutamine helps maintain the gut lining by providing main fuel for enterocytes, supporting normal gut function.

The Sustamine variant improves uptake and stability of glutamine, helping ensure ongoing availability of this amino acid for gut cell turnover and barrier health.

This supplement follows EFSA guidance on nutrients that support normal bodily function and avoids disease claims.
