Know Your Dose: LSC100 + Caffeine Dosing & Delivery Guide
Curated by The Dose, by LSC100® 13 cards Updated Nov 2026
100mg of caffeine is about one cup of brewed coffee. This stack answers what people ask before switching formats: how much caffeine a day is too much, how coffee and energy drinks compare, whether caffeine absorbed in the mouth hits faster than a swallowed pill, when to stop before bed, how to quit coffee without the withdrawal headache, what sugar-free candy means for your teeth, and how caffeine fits with ADHD. Sources are FDA, Mayo Clinic, Cleveland Clinic, CHADD and peer-reviewed research. LSC100 pairs 100mg caffeine with 100mg L-theanine in a lozenge that dissolves on your tongue, sold in 3, 10 and 20 packs at takelsc.com.
