BCAA, Ginseng and Astragalus Saponin Extract, Whey Protein, Pharmacokinetics
Brief summary
This study gave healthy people supplements with ginseng and astragalus saponin extracts (AstraGin), combined with whey protein, to explore whether it can promote amino acid absorption and thereby enhance protein nutritional status and muscle function. This trial is a randomized, double-blind, crossover trial, and the research subjects are adult healthy subjects.
Detailed description
A randomized-double blind, crossover human trial. 30 healthy adults, subdivided into two groups, are randomized into treatments and placebo groups to ensure equally balanced randomization and comparability, considering factors including age, sex, and diet. (2) The 1st round: Before each study day, all subjects took a 50 mg AstraGin/placebo (maltodextrin) capsule at 9 p.m. and began fasting for 12 hours, except for a small amount of water the night before the experiment. On each study day, all subjects collected their first blood sample at 9 a.m. from the median cubital vein using the indwelling catheter method. After the first blood collection, all subjects took 50 mg AstraGin/placebo and 35 g of whey protein with 250 mL water. (3) Additional blood samples were collected at 0, 15, 30, 45, 60, 90, 120, 150, and 180 min to analyze the plasma concentration of amino acids. (5) The washout period is seven days, during which the subjects maintain a stable lifestyle and dietary habits. The 2nd round: All subjects take a 50 mg Placebo/AstraGin capsule and conduct the procedure (same as the 1st round)
Interventions
DIETARY_SUPPLEMENTAstraGin (Ginseng and Astragalus Saponin Extract)
In this study, we are investigating the effects of AstraGin on healthy adults. The testing sample is orally administrated to subjects with 35g whey protein + AstraGin. After intervention, a 180-min kinetics study of plasma amino acids was conducted.
DIETARY_SUPPLEMENTPlacebo
In this study, we are investigating the effects of AstraGin on healthy adults. The testing sample is orally administrated to subjects with 35g whey protein + Placebo. After intervention, a 180-min kinetics study of plasma amino acids was conducted.
