The Liver’s Crucial Role in Kratom Pharmacology
Groundbreaking research conducted at the University of Florida demonstrated that raw mitragynine itself is largely a pro-drug. In human liver microsomes, the phase-I cytochrome P450 enzyme CYP3A4 oxidizes the C9 position of the mitragynine indole ring, converting mitragynine to 7-hydroxymitragynine.
The Problem of Genetic Polymorphism
Human CYP3A4 activity varies by up to 20-fold among individuals due to genetic genetics, diet (e.g., grapefruit juice), and concurrent medications. This explains why some people feel strong effects from raw leaf powder while others feel nothing at all.
The Solution: Pure Pre-Formulated 7-OH
By bypassing hepatic bio-transformation entirely, pure pre-isolated formulations like ZOHM Natural 40mg deliver predictable, reproducible alkaloid activity regardless of individual liver enzyme profiles. View our full testing on our Lab Tests Page.
