Overview

BulkSupplements L-Theanine provides 100g of pure L-theanine powder with no fillers, flavors, or additives. At 200mg per serving, this provides 500 servings for under $24 — about 4 cents per serving. L-theanine is an amino acid found naturally in green tea that promotes alpha brain wave activity, associated with a state of calm focus. It's most commonly stacked with caffeine (the 'smart caffeine' stack) where L-theanine smooths out caffeine's jittery effects while preserving the alertness and focus benefits.
