## Features

- We've developed a premium-quality Theanine supplement that contains an extra-large dose of 400mg per serving. These are 2x most other l Theanine 200mg capsules and 4x other l Theanine 100 mg capsules on the market.
- Theanine is an Amino Acid found in tea leaves, particularly in green tea. It's been used for centuries to help people relax, reduce stress, and promote a sense of calm.
- One of the key benefits of L-Theanine is its ability to promote relaxation and reduce stress. Cortisol is a hormone that is released in response to stress. Studies have shown that L-Theanine powder can help to maintain cortisol levels within normal range. L-Theanine can help to promote relaxation and calmness, without causing drowsiness.
- Another benefit of Theanine is its ability to improve cognitive function and mental clarity. Theanine has been shown to increase alpha brain waves, which are associated with creativity, focus, and mental alertness. It's also been shown to improve memory and learning ability, making it a great choice for students or professionals who need to be at their best mentally.
- At our company, we're committed to using only the highest quality, all-natural ingredients in our supplements. Our Theanine supplement is no exception. We use only non-GMO ingredients, and our capsules are easy to swallow and ensure efficient absorption. Our supplement is also third-party tested, so you can be sure you're getting a safe and effective product.
