Ultra-pure for maximum bioavailability. Pure free form amino acid with no fillers or additives. HPLC verified.

L-Theanine is a natural phytochemical found in Japanese green tea. L-Theanine is a non-essential amino acid that is present in the brain and is a close relative of Glutamate. Studies indicate that L-Theanine interacts with the neurotransmitter, GABA (Gamma-Aminobutyric Acid). GABA, known for its importance in nervous system functioning, works with the mood centers of the brain. Studies in Japan show that L-Theanine helps support the body's ability to deal with PMS and occasional, everyday anxiety.

L-Theanine is a unique amino acid found almost exclusively in the green tea plant (Camellia sinensis) and is the primary ingredient contributing to the unusual taste of green tea. Animal studies have shown that L-Theanine crosses the blood brain barrier, increases dopamine and GABA levels in the brain, and inhibits the stimulatory properties of caffeine. Human studies have shown that taking L-Theanine results in the emission of brain waves associated with a state of relaxation.

L-Theanine exerts beneficial effects on brain metabolism and induces relaxation without causing drowsiness, as measured by increased generation of alpha-waves. L-Theanine may improve learning ability and sensations of pleasure by affecting dopamine and serotonin neurotransmitters in the brain. Also, L-Theanine exerts protective effects on the brain by antagonizing glutamate toxicity.

L-Theanine helps promote a restful, relaxed state while maintaining daytime alertness. L-Theanine is also scientifically shown to support healthy blood pressure levels that are already within normal range.

Take the edge of mounting stress, and relax naturally with L-Theanine.

Notice: This amino acid, L-Theanine is easily confused with the amino acid L-Threonine. They are spelled similarly but are two different amino acids. If you are looking for L-Threonine click here.

Warm But Pills
Size: Full, Color: Purple
Overall the Intel Design jersey knit bed sheets are just like sleeping between a huge cotton blend t-shirt. It's soft, cozy, and warm to the touch. However after only two washings, the fabric begins to pill significantly and a lot of lint collects in the clothes dryer's lint trap. The new sheets now look five years old and stratches the skin. The warmth does provide longer periods of restful sleep. Not sure how long the fabric will last, as it appears a bit tired and worn. The initial purple color also appears noticeably duller. Good value at first, but probably will replace in a few months, so not much savings in the long run

3 washes and rough as a cob.
Size: King, Color: Teal, Size: King, Color: Teal
Got these about 2 months ago, the feel soft enough and fit well, think stretchy T shirt material, but after three washes they have pilled all over and become very rough. Just as bad as the two year old set I replaced with these. Will not purchase again.

Good for between seasons
Size: Twin, Color: Blush
Very nice jersey sheet set! The color is perfect and it washed well. The weather is too warm for flannel, but too cold for our regular knitted sheets. These sheets are thin but warm. The perfect “between seasons” weight to keep my toddler cozy at night. We’ll see how they hold up over time but so far so good. Very happy with my purchase!
