Product Description
Nerves in the start corral and a mind that will not settle the night before a race are two different problems with one thing in common, you want to relax without losing your edge. An amino acid called L-theanine is one way to get there. L-Theanine from Integrative Therapeutics helps promote a restful, relaxed state and supports a healthy stress response, all without diminishing daytime alertness.
Stay alert while you relax – L-Theanine helps promote a restful, relaxed state without diminishing daytime alertness. You can use it during the day or as part of an evening relaxation routine.
A healthier response to everyday stress – Controlled clinical trials have shown that L-theanine can support a healthy stress response. That helps you maintain a sense of calm and balance when everyday stressors stack up.
Brain waves linked to relaxation – Human studies have found that supplemental L-theanine promotes the generation of alpha brain waves, suggesting a state of relaxation. Alpha waves are the brain activity pattern linked with relaxed wakefulness.
L-theanine is an amino acid, and each two-capsule serving provides 200 mg. In a small early study of eight volunteers, a 200 mg dose generated alpha brain waves, which are measured with electrodes on the scalp. The effect showed up in the first hour.
How to Use L-Theanine
Dose: Adults take 2 capsules one to two times daily.
Timing: Relaxation support begins within 30 to 60 minutes, so taking your capsules about an hour before you want to settle in gives them time.
