Supports Relaxation.L-theanine directly stimulates the production of alpha brain waves, which creates a deep state of relaxation. Research with human volunteers has demonstrated that L-theanine creates its relaxing effect approximately 30 to 40 minutes after ingestion. (1)
Supports Cognitive Function.L-theanine stimulates alpha-brain waves, which increase mental alertness L-theanine also plays a role in the formation of gamma-aminobutyric acid (GABA), which regulates neurotransmitters and helps maintain relaxed levels of neuron activity. (2)
Supports Healthy Mood.In addition to L-theanine, L-Theanine Calm-Plex contains two additional mood-enhancing ingredients, 5-HTP and GABA. These natural compounds work synergistically to help maintain balanced neurotransmitter levels in the brain, promoting a strong sense of well-being and healthier mood.
