For years the scientific community has argued about absorption rates and bioavailability of vitamins and other nutrients. L-arginine Plus critically analyzed its formula to try to determine how much of the 5000mg of the amino acid L-arginine is absorbed by the body. It was determined that depending upon what other items were digested with L-arginine impacted the absorption rate. Some foods and vitamins increased the absorption rate while others decreased it.
Looking for a solution, L-arginine Plus partnered with NuLiv Sciences to try to determine an ingredient that could be added to the formula to develop consistent absorption rates, maximizing the effectiveness of ingredients within the formula. NuLiv crafted the proprietary formulation, AstraGin. The idea behind AstraGin was to create a formulation that increased the body’s ability to absorb nutrients.
Consisting of ginsenosides extracted from Panax notoginseng and alcohol fraction from Astragalus membranaceous, AstraGin has been demonstrated in vitro, in vivo, and in human consumption to significantly promote and improve absorption of amino acids, glucose, and vitamins. It specifically does this through the regulation and paralleled alteration on both the protein and mRNA expression levels of the Na+/glucose cotransporter 1 (SGLT1) gene.
The two herbs, Astragalus membranaceus and Panax notoginseng, from which NuLiv's proprietary fractions NL-F002 and NL-F007 in AstraGin were extracted, purified and enriched from, have been used in Chinese traditional medicine for thousand years for its ability to increase and improve absorption, circulation, and cellular metabolism.
NuLiv's in vitro studies have shown that AstraGin specifically increases the arginine absorption by 66.7% in Caco-2 cells, a standard used by pharmaceutical companies to study the absorption of new drug candidates. NuLiv's in vivo studies have shown that AstraGin increases the gene expression level of CAT1 mRNA and transporter protein in Jejunum and Ileum in rats. CAT1 is the primary gene that regulates the absorption of cationic amino acid group (arginine, lysine, and histidine). From historical, evidential, and NuLiv's own in vitro and in vivo studies, AstraGin has demonstrated to significantly increase the absorption of arginine.
