Science
Mechanism of Action
Functions through a complex matrix of polyphenols, lignans, and monoterpenes (including limonene and alpha-pinene) that neutralize free radicals via oxidation-reduction reactions forming stable dimers. Additionally inhibits bacterial and fungal growth while suppressing inflammatory enzymes that contribute to oxidative stress.
