Has tension become part of your daily routine? Stressful days often lead to restless nights, making it harder to get the restorative sleep you need to take on tomorrow. If you’re looking for a way to break the cycle, Suntheanine may help, supporting daytime focus and calm while enhancing relaxation so you can rest more easily at night.
Below is your updated guide to Suntheanine, including information about the new clinically meaningful 200 mg formula.
What Is Suntheanine?
Green tea has been used for centuries for its wellness benefits. One of the key compounds behind these calming effects is L-theanine, an amino acid known for promoting a relaxed state of mind without causing drowsiness.
Suntheanine® is the original, most clinically researched form of L-theanine. Unlike generic L-theanine, it is produced using a patented enzymatic fermentation process that creates a highly pure, consistent form that matches the structure used in clinical studies. This precision is why Suntheanine is trusted by wellness seekers, practitioners, and researchers worldwide.
With more than 50 published clinical studies, Suntheanine has been shown to support:
- A calm, focused mental state*
- Improved clarity and attention*
- Healthy stress response*
- Better sleep quality*
Introducing the New Suntheanine 200 mg Formula
The latest version of Suntheanine now provides 200 mg of pure L-theanine per capsule, a dose that reflects what many clinical studies consider a meaningful level for supporting calm and focus.
This upgraded formula offers:
- 2× the strength of traditional 100 mg capsules
- A more impactful daily dose for noticeable calm and clarity*
- The same patented purity and consistency Suntheanine® is known for
- Fast-acting benefits, often felt within 30 minutes
The new Suntheanine 200 mg strength is ideal for those with demanding schedules, higher stress levels, or anyone wanting an efficient once-daily approach.
How Does Suntheanine Work?
Stress activates beta brain waves, which are associated with tension, worry, and difficulty concentrating. Suntheanine helps shift the brain into a more relaxed state by increasing alpha brain wave activity.*
- Alpha waves promote calm, focus, and mental clarity.
- Beta waves are linked with stress and restlessness.
By naturally enhancing alpha wave activity, Suntheanine supports a balanced state often described as calm yet alert, similar to the mental clarity experienced during deep meditation.
How Should You Use Suntheanine?
The recommended amount of L-theanine varies from 50 mg to 200 mg per day. Because many research studies use 200 mg to achieve meaningful results, the new Suntheanine 200 mg capsule provides a convenient, clinically aligned serving in just one dose.
Key usage notes:
- Benefits typically begin within 30 minutes
- Effects may last up to 8 hours, depending on the individual
- Does not cause drowsiness, so it can be taken at any time of day
- Suitable for daytime focus, evening relaxation, or both
For those experiencing high stress or restlessness, starting with the full Suntheanine 200 mg dose may offer the most noticeable support.
