Astragalus & Panax notoginseng Extract

A patented (NuLiv Science) blend of highly fractionated Astragalus membranaceus and Panax notoginseng root extracts, marketed to enhance intestinal absorption of amino acids, peptides, glucose, and vitamins by upregulating nutrient transporter expression. The supporting evidence is almost entirely in-vitro (Caco-2 cell models) and animal studies, the majority conducted or funded by the manufacturer; there are no independent human RCTs demonstrating improved nutrient absorption or any clinical outcome in people. Per our evidence hierarchy this is mechanistic-tier data and should not be used for clinical efficacy claims. Distinct from the standalone Astragalus Root entry, which is dosed and studied as a herb in its own right.

Limited clinical evidence. Marketed absorption enhancer; supporting data is primarily in-vitro and animal studies funded by the manufacturer (NuLiv Science), with no independent human RCTs
