Caffeine and L-theanine: the calm-focus pairing on Space Dust™
UPDATED 2026-09-13
Why Space Dust pairs 200 mg caffeine anhydrous with 100 mg L-theanine — and how that shows up on a fully disclosed nootropic label.
Caffeine plus L-theanine is one of the most common pairings in focus supplements. Space Dust prints both amounts: 200 mg caffeine anhydrous and 100 mg L-theanine per 2-capsule serving.
What the pairing is used for
Caffeine supports alertness. L-theanine is included alongside it when people want that alertness with a smoother perceived edge than caffeine alone. That is structure/function language — not a medical claim, and not a substitute for sleep.
How it sits next to TeaCrine®
The same serving also lists 125 mg TeaCrine® (theacrine). Command Center cites human research on theacrine for sustained energy and mood support. Follow the serving directions; exceeding them will not improve results.
Practical use
Take two capsules with water and a light meal. First-time users may take one capsule. Do not combine Space Dust with other caffeinated drinks or supplements. If you are subject to workplace or athletic screening, read the Supplement Facts and our FAQ on screenings before use — outcomes are never guaranteed.
