AstraGin® is a patented bioavailability and gut health ingredient that has demonstrated in multiple in-vitro, in-vivo and a human clinical to support enhanced absorption of certain nutrients and subsequent bioavailability of nutrients in the body.

In an animal study, AstraGin® also demonstrated it may help reduce inflammation in the gut and support a healthier microbiome. Commercially launched in 2011, AstraGin® has become a popular ingredient for pre-workouts, amino based formulas, and proteins.


What it does

AstraGin®’s working theory operates on two principles, activation of certain transporter proteins, and support of an optimal gut environment.

In internal and published studies, AstraGin® has shown it can positively affect uptake of arginine, beta-alanine, citrulline, creatine monohydrate, curcumin (curcumin + fat and curcumin + black pepper extract), folate, leucine, lysine, proline, tryptophan and more. By reducing general inflammation in the intestines (through MPO reduction) AstraGin® ensures a systemic, well-rounded health system.

AstraGin® has both a 28 and 90-day toxicity study and is GRAS affirmed. It is also Informed-Choice and Informed-Sport certified for competitive athletes.

How it works

90% of the nutrients our body intakes is absorbed in the small intestines. Absorption can be passive or active. We theorize that AstraGin® supports the increased activation of certain transporter proteins, which in turn increases the uptake of certain nutrients.

It is estimated that up to 45 million Americans have a sub-optimal GI tract (as defined by Irritable Bowel Syndrome). We also know that our gut health is tied to almost everything else in our body, from our immune system to even how our brain functions. Supporting a positive and healthy gut environment with AstraGin® will help with holistic improvements across the body.


The optimal dose of AstraGin® is 50mg. We have found that there is statistically significant uptake as low as 25mg.
