The 10:1 concentration delivers clinically meaningful carvacrol levels while the oil matrix supports absorption of these lipophilic compounds.

Carvacrol rapidly absorbed orally; Cmax at 1-2h; distributed to brain, liver, kidneys PMID: 22936082

Carvacrol ~50% bioavailability; lipophilic nature enables rapid passive absorption PMID: 25629806

Carvacrol in blood 30 min post-ingestion; dose-dependent plasma levels PMID: 30423897
