T o support any cellular repair in the body, we need protein, which is broken down into amino acids required for regeneration. And for a healthy gut membrane , two specific amino acids play a pivotal role in supporting the repair of this delicate tissue:

1. L Glutamine - a key building block for proteins that maintain cellular health and tissue repair. More importantly, it’s the preferred food of the cells lining the gut wall.
2. N-Acetyl L-Cysteine (NAC) : The precursor to glutathione, the body’s master antioxidant, NAC protects cells from damage caused by free radicals and supports cellular repair through enhanced glutathione production.
   
   

L-Glutamine and Gut Health

L-Glutamine plays a vital role in the regeneration of epithelial cells in the GI mucosa lining, particularly during times of critical illness, trauma, intestinal disease, or after excessive loss of lean body mass. L-Glutamine is so important to gut health that low concentrations are linked to gut permeability and inflammation making it a crucial nutrient for resolving leaky gut.

As the preferred fuel for the cells lining the gut wall, L-Glutamine supports their repair and regeneration. This helps restore the intestinal lining’s integrity, maintain the right pH balance, and eliminate the challenges of leaky gut. Research in human health suggests that glutamine supplementation begins showing effects within 30 days, with significant gut lining repair typically achieved in around 12 weeks.

L-Glutamine works synergistically with NAC to enhance glutathione production, further supporting cellular health and protection.

NAC and Glutathione

N-Acetyl L-Cysteine is a vital precursor to glutathione, the body’s most powerful natural antioxidant. By replenishing glutathione levels, NAC helps protect cells from oxidative stress and supports overall cellular repair.

Complementary Support from Marshmallow Root

To enhance the benefits of L-Glutamine and NAC, GutAminos also includes Marshmallow Root , used as a remedy for centuries to treat digestive conditions. It actively promotes the growth of intestinal cells with research showing promise in its antioxidant properties and gastroprotective effects, particularly for ulcers. Marshmallow Root actively promotes the growth of intestinal cells, supporting the repair of leaky gut and strengthening the gut lining.
