You may ask yourself, would L-Glutamine help me? If you have the following symptoms, taking L-Glutamine could be beneficial:

  • Anxiety
  • Sugar or alcohol cravings
  • Constipation or diarrhea
  • Poor immune system
  • Low muscle mass
  • Poor wound healing
  • Slow recovery after workouts

L-Glutamine is one of the most important nutrients for a healthy digestive tract because of its ability to maintain the integrity of the intestinal wall. This amino acid (in fact it’s the most abundant amino acid in the body) heals all tissue in the body, especially those irritated tissues in the digestive tract. It is also known as the calming amino acid since it’s very effective at reducing anxiety, as well as sugar and alcohol cravings.

At Nutritional Weight & Wellness we always look for real food sources first. For this important amino acid, we’re lucky that all animal protein foods are great sources of glutamine. The long list includes beef, bison, chicken, fish, free-range eggs, grass-fed dairy, lamb, pork and turkey. However, if you or someone in your family isn’t eating sufficient amounts of animal protein and/or has the above symptoms we recommend taking a glutamine supplement. 

A 2011 study published in the Yonsei Medical Journal found that glutamine supports the immune system and is especially beneficial for patients in the hospital and those fighting viruses or overwhelming infections. (Kim, 2011) Clinically, we have found that our clients looking for better digestion and fewer cravings have greatly benefited from an L-glutamine supplement.

If you have anxiety, sugar or alcohol cravings, constipation or diarrhea, a poor immune system, low muscle mass, poor wound healing or slow recovery after workouts, you may want to supplement with L-glutamine.
