Rather than relying on a single mechanism, AstraGin works through multiple complementary pathways to support how nutrients are absorbed and utilized within the body.* Clinically studied at low daily doses (50100 mg), AstraGin has been shown to support absorption and bioavailability of key nutrients including amino acids, promote activity of nutrient transport pathways, support intestinal barrier function and cellular integrity, help maintain a balanced gut microbiome, support pathways associated with nitric oxide metabolism, and promote normal cellular energy production.* From a formulation perspective, AstraGin is effective at low doses and well-suited for use alongside vitamins, minerals, amino acids, and botanicals designed to support overall nutrient utilization without disrupting normal gut function.* Ingredient Manufacturer Link: *These statements have not been evaluated by the Food and Drug Administration
