Green Tea Extract Risk
Concentrated EGCG (the active compound in green tea) is liver-protective for most people—but potentially toxic in high doses for a small genetic group. Your processing capacity decides whether 800 mg capsules are a smart supplement or a risk you shouldn't take.
What this measures
How your DNA shapes green tea extract risk.
UGT1A1 is the liver enzyme that conjugates EGCG — the active polyphenol in green tea extract — for clearance. CYP3A4 contributes upstream. At cup-of-tea doses, this system handles EGCG without strain. At concentrated supplement doses, the enzyme’s capacity becomes the limiting factor.
Carriers of reduced-activity UGT1A1 variants (the same variants involved in Gilbert’s syndrome) are associated with slower EGCG clearance — and a higher risk of hepatotoxicity from concentrated extract supplements. The risk scales with dose; brewed tea remains low-concern across nearly all variant patterns.
Fasting amplifies absorption and risk. Co-administration with curcumin, certain medications, or alcohol stacks the hepatic load. Adequate protein status protects hepatic glutathione, which buffers the system. Spreading doses across the day instead of single high doses reduces peak exposure.
A 500mg EGCG capsule is a different conversation from a cup of matcha — and which variant pattern you carry decides whether it’s a tolerable supplement or one to skip in favor of tea itself.

Green Tea Extract Risk renders as a dark-background card with a color marker calibrated to your specific variants. The card opens with the gene mechanism, shows your result at a glance via that marker, and closes with a practical, mechanism-led recommendation — what to eat, what to time, what cofactors to support.

Questions people ask
About Green Tea Extract Risk.
- How does my DNA influence green tea extract risk?
- How efficiently your body extracts what it needs from a meal is written in a network of genes that govern lactase persistence (MCM6), gluten response (HLA-DQ), insulin signaling (TCF7L2, IRS1), and the caffeine clearance enzyme (CYP1A2). Two people on the same plate can experience completely different downstream effects on energy, satiety, and inflammation.
- What kind of test do I need to see my Green Tea Extract Risk result?
- Whole-genome sequencing at 30× clinical depth. Consumer SNP-chip tests like 23andMe or AncestryDNA only read ~0.02% of your DNA and miss most of the variants this analysis needs. Mosaic reads all 3 billion base pairs and produces the full 108-insight report.
- How is Green Tea Extract Risk different from clinical lab testing?
- Clinical labs measure downstream biomarkers — blood levels, hormone values, metabolic byproducts — at a single point in time. Genomic insights like Green Tea Extract Risk reveal the underlying variant that shapes the biology, which is constant for life. The two are complementary: labs show the current snapshot; genomics shows the long-term tendency and where lifestyle leverage is highest.

Caffeine Jitters
Adenosine receptor variants decide whether coffee feels like rocket fuel or instant anxiety. Your version tells you if caffeine is a legitimate performance tool—or a stressor you've been dosing yourself with daily without realizing the cost.

Caffeine Metabolism
Fast metabolizers clear caffeine in 3–4 hours; slow metabolizers still have half left at bedtime. This explains why some people drink espresso at 8 p.m. and sleep like babies—and why that will never be you (or vice versa).

Gluten Related Immune Response Risk
Beyond celiac, some immune systems quietly react to gluten with brain fog, joint pain, or fatigue. Knowing your risk clarifies whether going gluten-free is medically relevant or just trendy—for you specifically.

Grain Sensitivity
Certain grain compounds can shift excitatory neurotransmitters in sensitive people. If you're one of them, bread or takeout can trigger anxiety, restlessness, or poor sleep without any classic digestive symptoms. It looks like "stress," but it's dinner.

Impact of Dairy Fat on Weight
Full-fat dairy makes some people leaner (better satiety, improved hormones); others store it straight to their waistlines. Your genotype predicts which camp you're in—and settles the skim vs. whole milk debate for good.

Insulin Resistance
Genetic predisposition to insulin resistance varies widely—and it's not just about weight. Higher-risk individuals benefit from earlier carb timing, resistance training, and preventive strategies, often decades before blood sugar becomes an official problem.
