The Moldavian dragonhead extract (hereafter referred to as MDH Nu sd) was prepared as previously described [27], with some modifications. In short, the dry aerial parts of Dracocephalum moldavica L. were extracted with de-ionized water for 1 hour at 85-90°C by percolation. After vacuum concentration, the liquid extract was then spray-dried on 50% maltodextrin as a carrier (DracoBelle™ Nu sd, provided by Mibelle Group Biochemistry, Buchs, Switzerland). This process ensures a content of at least 2.5% of total flavonoid-glucuronides in the extract powder. The detailed nutritional values are found in Table S1.
