Helps Alleviate Leaky Gut Symptoms

L-Glutamine has been proven to seal cracks, holes and fissures in the gut lining that lead to bloating, gas, discomfort, pain, reflux, food intolerances, constipation and loose stools.

Supports The Elimination of Sugar Cravings

L-Glutamine can have a stabilising effect on blood sugar levels and may create a ‘glucose equalising effect’ in the body. This could reduce unhealthy cravings for sugary foods or drinks.

Promotes Easier And Healthier Weight Loss

L-Glutamine can correct bacterial imbalances of Firmicutes that extract more calories from food, causing excessive fat storage. This correction could trigger healthy, steady weight loss.

The Health Benefits of Ultra Absorb L-Glutamine

What It Does and How It Does It

Ultra Absorb™ L-Glutamine is a plant-based, pure and ultra-fine form of L-Glutamine. It’s specifically formulated for women with gut problems so it can be easily absorbed into the gut lining for faster healing.

L-Glutamine is the most abundant amino acid present in your system. It makes up between 30% and 35% of the amino acid nitrogen you find in your bloodstream. This abundance earned it the title of a “conditionally essential” amino acid.

L-Glutamine has been shown by 217 scientific studies to seal cracks, holes and fissures caused by Leaky Gut Syndrome

Additionally, clinical research labs are now showing that L-Glutamine can help non-dieting women lose weight, increase muscle mass, overcome bacterial overgrowths and reduce sugar cravings.

It supports metabolic processes, as well as the muscular system. It’s also great for repairing damage due to oxidative stress, trauma or injuries, and returning muscles to higher performance levels.

The Science Behind the Ingredients in Ultra Absorb L-Glutamine

Ultra Absorb L-Glutamine promotes rapid cell regeneration to start restoring the gut lining (within 30 days or less). It can enable the gut cells (enterocytes) to regenerate at faster levels which seal the tight junctions in the gut and can restore the gut lining to a healthy state faster.

L-Glutamine may reverse the nutrient deficiency and malabsorption caused by Leaky Gut Syndrome that can trigger hair loss or thinning. Once the body starts assimilating all the important minerals from food, the hair can go back to its natural thick state within 30-60 days.

L-Glutamine can help eliminate the chronic digestive problems that lower the quality of life such as bloating, gut pain, discomfort, gas, wind, belching, acid reflux, constipation, and loose stools.

Ultra Absorb L-Glutamine can increase resilience against food sensitivities that make daily meals difficult to tolerate. This supports the reintroduction of foods or ingredients that may now be avoided.

Inflammation and cellular damage have been identified as “hallmarks” of a leaky gut. Recent scientific evidence shows that system-wide inflammation levels may be significantly lower in people who take L-Glutamine than in those who do not take it.

The science confirms—those with IBS have 38% lower levels of L-Glutamine in their bodies compared to those that do not have IBS. This means that taking L-Glutamine could eliminate the digestive discomfort and symptoms associated with this syndrome.

Ultra Absorb L-Glutamine has been shown to protect the gut lining from further damage and help balance out mucosal production in the gut. This can eliminate diarrhea, abdominal discomfort and painful gas.

L-Glutamine helps normalise the inflammation linked to depressive and anxious thoughts by helping heal the gut that stores upwards of 79% of the body’s serotonin—the happiness molecule.
