Berberine is known to inhibit certain cytochrome P450 enzymes (particularly CYP3A4 and CYP2D6) and may affect P-glycoprotein, a transport protein involved in drug elimination
This may be because elevated interleukin-6 (IL-6) concentrations in response to exercise stimulate PYY and GLP-1 levels [16] and suppress ghrelin expression [17], along with a redistribution of blood flow from gut hormone release sites to active muscles that may decrease acylated ghrelin due to decreased activity of the ghrelin O-acyl transferase (GOAT) enzyme, which is required to acylate ghrelin into its active form [18]
this is in agreement with the findings of the same study that the HPLC assay can provide an accurate determination of D-Carnitine from samples with fairly high concentrations as well as those with low concentrations
