Savvy athletes know that lean mass gains are the result of equal portions of high-intensity workouts and high-quality rest. If the second part of that all-important equation could use some improvement, consider ProSource L-Theanine. The amino acid L-Theanine, found in green tea, has been shown to help with stress support and relaxation, without feelings of drowsiness. Research illustrates theanine's capacity to help stimulate the alpha waves within the brain, which helps to create a state of relaxation and mental alertness. L-Theanine is also involved in the formation of the inhibitory transmitter GABA (gamma amino butyric acid). GABA influences the levels of two other neurotransmitters to help support a state of calm and relaxation. In addition, human studies on L-Theanine have also shown potential for helping to improve memory & concentration. Now you can take advantage of these valuable benefits with L-Theanine from ProSource—an innovative compound from an innovative company. Take it easy with L-Theanine!

Suntheanine is the best quality of l-theanine you can get! Can definitely feel it work. Use it to help with stress and to get a good nights rest after training or a heavy workout. I also combine it with high doses of caffeine (200+mg) for pre-workout or when I need a pick-me-up for study sessions.

My muscles tense up so bad in my sleep that it's damn near impossible to get out of bed in the morning. I started taking two of these two-three times a day and have felt almost no pain. The relaxation is very evident love this stuff. Magic.

Take this about an hour or so before an event that might make you nervous or create a degree of anxiety. You'll find that you'll be able to confront the situation more confidently because it does seem to effectively relax you thereby allowing you to focus on what you need to focus on instead of wrestling with nerves.
