## What is Caffeine Mode?

Caffeine Mode helps you drink smarter — not more.
Tailored to your metabolism, coffee type, and performance goals, Caffeine Mode tells you the perfect time to drink coffee — for maximum effect.
Why it works

Backed by world-class pharmacokinetic modeling and peer-reviewed science, Caffeine Mode is the first consumer app that recommends when to drink caffeine based on real biochemistry, not vague timers.

Scientific Foundations:
	•	 NCBI Pharmacology: Caffeine half-life of 3–7 hours
	•	 CYP1A2 enzyme studies: Major genetic variation in metabolism speed
	•	 Adenosine receptor research: Optimal plasma level 1–3 mg/L
	•	 Pharmacokinetics: Peak concentration ~45 minutes post-ingestion
	•	 ISSN (Int’l Society of Sports Nutrition): Evidence-based dosage standards


 Powered by science — not guesswork

1. Pharmacokinetic Modeling
	•	Bioavailability: 99%
	•	Volume of distribution: 0.6L/kg
	•	Time to peak concentration: 45 minutes
	•	Minimum effective dose: 1.0 mg/L
	•	Optimal performance zone: ~3.0 mg/L

2. Intelligent Timing Algorithm
	•	Reverse-PK engine to calculate best caffeine timing
	•	Effect duration computed based on decay curves
	•	Multi-factor confidence scoring
	•	In-app scientific explanations for each recommendation
