L-theanine is an amino acid commonly found in tea. Together with caffeine, it may produce a distinct cognitive enhancement profile without the jitters or other side effects. L-theanine is able to cross the blood-brain barrier and affect the brain directly. In the brain, it may target brain chemicals that regulate arousal, anxiety, pleasure, and attention. L-theanine increases brain serotonin and dopamine levels, which may improve memory and learning. It also increases the levels and effectiveness of GABA, the body’s main inhibitory neurotransmitter, and stimulates alpha brain wave activity, which may cause mental relaxation, concentration, and deep REM sleep.

I’m really happy I found this product. I found that I more energy and less fatigue and anxiety throughout the day. Jarrow makes quality supplements, I only buy through them. There is no taste and the packaging is quite durable so you can stuff it in a backpack if you’re on the go

Theanine

The quality of Theanine, 100 mg supplement is noteworthy. Theanine, 100 mg is an excellent supplement for those seeking to promote relaxation, reduce stress, and improve mental clarity without the effects of caffeine or sedation. The packaging is usually sleek and informative, often coming in a dark-colored bottle that protects the contents from light and moisture. As a capsule supplement, Theanine has no taste, making it easy to swallow without any unpleasant aftertaste.

Great for relaxing

Theanine promotes waves in your brain to support relaxation. I use 100 mg of Jarrow Theanine right before bed along with 1 mg of Jarrow Melatonin and fall right to sleep. Some take Theanine during the day for relaxation, but I love it for a pre sleep supplement. Jarrow also has a 200 mg version of this product if you need a larger dose, but when I tried that, it actually gave me energy instead, so 100 mg for me. Some theanine products also have B6, so watch taking too much of that before bed.

Theanine 100, 100 mg

The quality of this supplement is excellent. In terms of effectiveness, I feel calmer and more composed during stressful situations, yet still alert and productive. The capsules are easy to swallow, odorless, and gentle on the stomach. The packaging is secure and keeps the capsules fresh, making it convenient to store or take on the go.

Jarrow package and design always gets me. Their package is at least one reason to buy and the ingredients are the second reason. Good dosage and quality. I liked this a lot.
