HERBS OF GOLD — L-THEANINE 200MG Stress & Relaxation | Mental Focus | 30 Capsules
DESCRIPTION
L-Theanine 200mg by Herbs of Gold is a clean, single-ingredient formula delivering a high-strength 200mg dose of L-Theanine per capsule using AlphaWave® — a purified, clinically studied form of L-Theanine that is specifically researched for its neurological effects. L-Theanine is a naturally occurring amino acid found predominantly in green tea leaves, and is the compound largely responsible for the calm, alert mental state associated with tea drinking — notably distinct from the jittery edge often associated with caffeine alone. What makes L-Theanine particularly interesting from a neuroscience perspective is its mechanism: it crosses the blood-brain barrier and increases alpha brain wave activity — the brainwave pattern associated with a relaxed yet alert, focused mental state. This is not sedation or drowsiness; it is a shift into what is often described as wakeful calm, making it particularly valuable for managing stress, anxiety, and mental tension without impairing cognitive function. AlphaWave® has been clinically studied specifically for this alpha wave-promoting effect, providing stronger evidence for this mechanism compared to generic L-Theanine sources. L-Theanine also supports the synthesis of GABA, dopamine, and serotonin — neurotransmitters involved in mood regulation and calm — and has been well studied for its ability to take the edge off caffeine-induced anxiety, making it a popular pairing with caffeine for clean, focused energy. At 200mg per capsule, this is a meaningful therapeutic dose — research consistently uses 100–200mg per dose for cognitive and stress-related outcomes, and a single capsule daily provides a targeted, well-dosed approach. Free from egg, milk, peanut, soy, tree nuts, animal products, gluten, lactose, and artificial colours, flavours, or preservatives.
