Caffeine gene test
Check caffeine genes from the raw DNA file you already have.
GenoSight can re-analyze a compatible 23andMe, AncestryDNA, or MyHeritage raw DNA file for caffeine-related variants, then explain CYP1A2 metabolism and ADORA2A sensitivity in a readable educational Foods & Drinks report.

What the caffeine report checks
Caffeine response is not one gene and not one rule. GenoSight separates clearance speed from sensitivity, then frames both against the amount and timing of caffeine you already use.
Check marker coverage before uploadingCYP1A2
Caffeine metabolism speed
CYP1A2 helps metabolize caffeine. GenoSight checks supported markers such as rs762551 when they are present in your raw DNA file.
ADORA2A
Caffeine sensitivity
ADORA2A is part of the adenosine-signaling pathway. Research has studied rs5751876 in relation to caffeine-induced anxiety, arousal, and sleep effects.
Context
Your habits matter
A caffeine report is more useful when it knows whether you drink no coffee, one morning cup, or energy drinks after lunch.
Useful, not deterministic.
A caffeine gene result can help explain why coffee feels different to different people, but it should not override your actual sleep, anxiety response, blood pressure, medications, or clinician guidance.
- Shows whether supported raw-file markers are present
- Separates caffeine clearance from stimulant sensitivity
- Explains why timing matters for sleep and jitters
- Keeps dosing and medication questions with a qualified clinician
Caffeine genes by raw-data provider
Before you know the rsIDs, the question usually sounds like whether your provider tests caffeine genes at all. These pages separate provider reports from raw-data marker coverage.
23andMe caffeine genes
Understand 23andMe report availability versus raw CYP1A2 and ADORA2A marker lookup.
Open guideAncestryDNA caffeine genes
Check what an AncestryDNA raw file can answer before interpreting caffeine metabolism or sensitivity.
Open guideMyHeritage caffeine genes
Use a MyHeritage raw DNA data file for marker coverage first, then keep caffeine findings in context.
Open guideUse your existing file
No new lab test required. Upload a compatible raw genotype file from 23andMe, AncestryDNA, or MyHeritage.
Clear privacy boundary
The raw genotype file is parsed into structured findings first. GenoSight does not send the raw file to the LLM.
Practical report framing
The report connects caffeine variants to your own coffee, tea, and energy-drink habits instead of giving a generic genotype blurb.
Evidence boundary
GenoSight cites the underlying research where it makes caffeine-related claims, while keeping the conclusion modest: variants can tilt response, but they do not determine what you should do by themselves.

FAQ
Can GenoSight tell me if I am a slow caffeine metabolizer?
GenoSight can analyze supported caffeine-related variants from compatible raw DNA files, including CYP1A2 markers when present. It reports educational tendencies, not a clinical diagnosis.
Which raw DNA files can I use for a caffeine gene test?
GenoSight accepts compatible raw genotype files from 23andMe, AncestryDNA, and MyHeritage. It does not analyze PDF reports, screenshots, FASTQ, BAM, or whole-genome VCF files.
Does a caffeine gene result tell me exactly how much coffee to drink?
No. Genes are one input. Your sleep, anxiety response, blood pressure, medications, pregnancy status, and clinician guidance matter more than any single variant.
Can I try the caffeine report before paying?
Yes. New accounts receive 250 free credits with no card required. The Foods & Drinks report currently costs 160 credits, so the free grant can cover a first caffeine-related report preview.
