L-Theanine
L-Theanine by Integrative Therapeutics is a clinically studied amino acid supplement designed to promote a calm, relaxed mental state without causing drowsiness or reducing daytime alertness.* It is frequently used to support stress resilience, focus, and nervous system balance—making it a versatile option for both daytime and evening use.
At Yarrow Holistic Center, L-Theanine is often included in personalized care plans for patients seeking natural support for stress, anxiety, and emotional balance, as well as sleep-related nervous system overactivation. It is particularly well suited for patients receiving guidance through telehealth consultations, where calming and focus-supportive supplements can be safely monitored and adjusted remotely.
Promotes Relaxation Without Sedation
L-Theanine is naturally found in green tea and is valued for its ability to promote relaxation while maintaining mental clarity.* Unlike sedative agents, it supports calm alertness—making it appropriate for use during the day or before bedtime.
Clinical research suggests L-Theanine may help:
- Promote a relaxed, focused mental state*
- Support a healthy stress response*
- Encourage calm without impairing concentration*
- Support nervous system balance during periods of tension*
This makes L-Theanine a foundational nutrient in integrative approaches to stress management.
How L-Theanine Works
Human studies have shown that L-Theanine promotes the generation of alpha brain waves—patterns associated with a relaxed yet alert mental state.* Controlled clinical trials also suggest it supports a balanced stress response without causing fatigue or brain fog.
Because of these effects, L-Theanine is commonly used in holistic and functional medicine settings.
Ideal for Holistic & Telehealth-Based Care
L-Theanine is frequently recommended within functional medicine and integrative internal medicine care plans.
Within a telehealth model, it may be combined with:
- Stress and nervous system regulation strategies
- Sleep hygiene and circadian rhythm support
- Mind–body and lifestyle interventions
- Other targeted nutritional or herbal supplements
This flexibility makes L-Theanine an excellent option for patients seeking gentle, non-habit-forming calming support.
