Clinical Applications
- Promotes Relaxation Without Causing Drowsiness
- Improves Focus, Attention, Learning Performance and Mental Clarity
- Improves Quality of Sleep
- May Support Blood Pressure Already Within the Normal Range
- Reduces Negative Side Effects of Caffeine
L-theanine alleviates nervousness due to overwork and decreases irritability by contributing to a variety of changes in the brain. Human studies suggest it is also helpful in improving focus, attention and mental clarity while reducing the negative side effects of caffeine.
Suggested Use:
1 capsule per day or as recommended by your health care professional.
L Theanine Benefits
Brain and Nervous System Support
Human studies have shown there is a significant increase in alpha brain waves within 40 minutes of ingesting L-theanine. Alpha brain waves are associated with a state of wakeful relaxation as well as focus and creativity. An eight-week, double-blind study found that 400 mg of L-theanine per day was safe and effective while also possessing neuroprotective, mood-enhancing and relaxation properties. A
The stress-buffering mechanisms of L-theanine have been connected to its ability to increase serotonin and dopamine production in the brain. Studies have shown L-theanine crosses the blood-brain barrier intact and can continue to balance neurochemistry by blocking glutamate transport, reducing levels of extracellular glutamate and supporting the release of dopamine and glycine from neurons.
Liver Health, Detoxification, Antioxidant Status and Cardiovascular Support
Research designed to study ethanol metabolism and hepatic toxicity in animals suggests L-theanine increases specific liver enzyme activity that reduces blood ethanol concentration within one hour of ingestion compared to controls. It is also assumed L-theanine’s effect on cytochrome P450 2E1 activity, glutathione recycling and antioxidant mechanisms enhances detoxification and preserves healthy liver function. L-theanine has also been shown to significantly impede hydrogen peroxide-induced cell death and therefore may play an important role in supporting liver health. Further studies demonstrate, along with green tea polyphenols, provides substantial antioxidant activity, which supports healthy LDL and oxidation levels and may subsequently benefit cardiovascular health. Animal and human research also suggests L-theanine supports healthy blood pressure already within the normal range due to its ability to diminish the negative side effects of caffeine.
