AstraGin® is a patented, plant-based compound providing full-spectrum gut support through enhanced absorption, microbiota and immune cell viability, and supporting a healthy intestinal wall environment

Mechanism of action

Enhances Absorption, restores gut wall integrity, promotes microbiota homeostasis, and activates the immune system

Scientific Statement on Mechanism of Action: AstraGin® enhances nutrient absorption by up-regulating nutrient transporters, such as CAT1, SGLT1, and FR. AstraGin® restores gut wall integrity by triggering an anti-inflammatory response and activating the mTOR pathway for rapid intestinal stem cell migration and differentiation in the inflamed intestinal mucosal barrier (epithelial cell and tight junction). AstraGin® promotes gut ecosystem homeostasis by the symbiotic effect of restoring gut wall integrity and increasing microbiota-immunity communication. Lastly, AstraGin® activates the immune system through the symbiotic effect of improved gut wall integrity and enhanced microbiota-immunity communication.


  • Enhanced nutrient absorption*
  • Supports a healthy intestinal wall environment at the cellular level*
  • Strengthens gut-based immune system*
  • Supports microbiota population in the gut*


A healthy gut is key to a healthy body and mind. The gut is home to 70% of the body’s immune system, and has a large impact on much of the body’s essential functions. Before entering circulation to be utilized by the body, consumed nutrients must first be absorbed through the gut. Although some nutrients and nutraceuticals are often poorly absorbed because of their poor water solubility, larger molecular size, structure instability, and other factors.


In the health and wellness industry companies have worked to overcome these barriers with a variety of approaches. Some absorption-enhancing nutraceuticals encapsulate nutrients that do not mix well with water into microscopic fat-soluble vesicles to solve the absorption problem which can be costly to implement.


Others achieve a higher concentration of nutrients in the body by suppressing specific metabolic enzyme complexes, delaying the transport time and metabolism of the nutrient. We believe specific botanicals in the optimal format, such as AstraGin®, can both address the challenge with cost-drivers and innovation in product formulas.


AstraGin® enhances absorption by increasing nutrient transporters within the gut through; such as

• CAT1 for arginine, lysine, and histidine absorption

• SGLT1 for glucose absorption

• FR for folate absorption


Unlike other absorption methods, AstraGin® works with the body’s normal functions to support the way amino acids, fatty acids, vitamins & minerals are naturally absorbed within the body.


Another limiting factor to nutrient absorption is inflammation of the gut. Chronic inflammation in the intestines, characterized by damage and inflammation of the mucosal barrier, affects the absorption of nutrients, the population of microbiota, and immune functions. AstraGin® promotes a healthy intestinal mucosal barrier by triggering an anti-inflammatory response and activating the mTOR pathway for rapid intestinal stem cell migration and differentiation in the inflamed area.


NuLiv Science in-vivo and clinical trials have shown a reversal of intestinal mucosal damage and inflammation when AstraGin® was administered. These same studies showed an indication of a positive microbiota environment when AstraGin® was administered as well as evidence of immune support; suggesting AstraGin® may support and promote a healthier gut barrier, microbiota population, and immune capability.*


The mucosal lining of the gastrointestinal tract is central to nutrient uptake and acts as a barrier against bacteria and toxins. Taking AstraGin® on a regular basis supports the body’s natural ability to absorb more nutrients, limit toxins from entering the body, provide a favorable eco-environment for microbiota, and support immune cell population and vitality. 1, 2, 3, 4
