Anesthetics Metabolism
Some people wake up from anesthesia quickly and clearly; others are groggy for hours or experience prolonged side effects. Your clearance rate predicts which camp you're in—valuable information before any procedure requiring sedation.
What this measures
How your DNA shapes anesthetics metabolism.
The CYP3A4, CYP3A5, CYP2D6, and CYP2B6 family handles the bulk of anesthetic clearance — from propofol (CYP2B6) to fentanyl (CYP3A4) to codeine and tramadol (CYP2D6). Each enzyme runs on its own variant set, which is why one client can clear propofol quickly and codeine slowly, or vice versa.
Carriers of CYP2D6 reduced-activity variants ("poor metabolizers") are associated with significantly reduced effect from codeine (which depends on CYP2D6 for conversion to morphine) and prolonged effect from tramadol. Carriers of CYP2D6 high-activity variants ("ultrarapid metabolizers") are associated with the opposite pattern — and elevated risk of opioid toxicity from codeine. CYP3A5 expression status splits along ethnic lines and shifts intraoperative dosing meaningfully.
Co-administered medications and certain foods (grapefruit juice inhibits CYP3A4 for up to 72 hours) shift effective clearance further. Stress, recent illness, and liver function all influence enzyme activity acutely. Genotype-aware dosing — used routinely in some clinical contexts — meaningfully reduces complication rates.
Surgical anesthesia is the rare scenario where pharmacogenomics changes immediate, life-affecting outcomes. Which CYP combination you carry decides whether standard dosing fits or whether the anesthesia team has reason to adjust — information that belongs in the conversation before any planned procedure.

Acetaminophen Metabolism
Your liver clears Tylenol at its own pace—fast, intermediate, or slow. If you're a slow processor, standard doses linger longer than they should, and "take two every four hours" might be too much for your system. This guides safe dosing and prevents accidental overload.
Read insight →Acetylation
This pathway handles histamine, caffeine, and a long list of chemicals and medications. Slow acetylators often experience fragrance sensitivity, medication side effects, or react to things that most people tolerate. Once you know, you can support the bottleneck instead of wondering why everything bothers you.
Read insight →Glutathione Support Needs
Glutathione is your body's master antioxidant—the one that recycles all the others. Some people produce plenty; others run chronically low without knowing it. Lower genetic output is common and responds well to precursors like NAC, glycine, and selenium. This is often the missing piece for people who "do everything right" but still feel run down.
Read insight →MTHFR Activity
MTHFR converts synthetic folic acid into the active methylfolate your body uses. Reduced function is common, affecting up to 40% of people. If you're one of them, standard prenatal vitamins and fortified foods won't cut it. Methylfolate supplementation bypasses the bottleneck entirely.
Read insight →Medication Metabolism
The enzyme family that processes roughly half of all prescription drugs. Your version determines whether standard doses work perfectly, cause side effects, or barely register. This prevents the trial-and-error prescribing that leaves people cycling through medications, wondering why nothing works right.
Read insight →Methylation
Methylation is the behind-the-scenes regulator of detox, neurotransmitter production, and gene expression. Suboptimal activity is surprisingly common—and highly responsive to the right form of B-vitamins. If you've ever taken B-complex and felt nothing (or worse), this is probably why.
