Genetics
This report is based on genetic variants near two genes that play a role in how your body handles caffeine. The first gene, CYP1A2, contains instructions for an enzyme that breaks down 95% of the caffeine you consume. The second gene, AHR, contains instructions for a protein that ramps up production of the CYP1A2 enzyme. Variants in these genes may affect how quickly the body breaks down and clears away caffeine.
