L-Theanine

1.What Is It?

L-Theanine is a non-essential amino acid that is most commonly found in green tea leaves. It can also be derived from certain edible mushroom species. Due to its ability to affect brain function, L-Theanine is considered a nootropic amino acid.

2.What Does It Do?

L-Theanine has the ability to cross the blood-brain barrier, where it acts as a non-sedative relaxing agent.

Specifically, L-Theanine works to block the binding of L-Glutamic Acid to Glutamate receptors in the brain, which results in the release of specific neurotransmitters that work to reduce feelings of stress and anxiety.

L-Theanine has also been shown to improve attention and mood when combined with caffeine. 

When used before exercise, L-Theanine has been shown to improve reaction times and reduce feelings of tiredness and mental fatigue.

As these combined effects are highly desirable for athletes competing in high stress, performance based sports, L-Theanine has become very popular with elite professional athletes.

3.When Do I Take It?

Due to the multitude of benefits provided by L-Theanine, it can be taken at a number of different times during the day. The most obvious is pre-workout, where it will support enhanced attention and reduced feelings of fatigue.

In addition to pre-workout use, supplementing with L-Theanine before any mentally demanding task can support enhanced concentration and improve memory and learning potential.

To take advantage of these performance enhancing properties of L-Theanine, it is best taken 15-20 minutes before exercise or any mentally demanding task.

To help reduce feelings of stress and anxiety, L-Theanine can also be taken first thing in the morning upon waking and last thing at night before going to sleep.

The most efficacious dose of L-Theanine is 100-200mg per serve.

4.How Long Does It Take To Work?

L-Theanine crosses the blood-brain barrier very quickly and starts working as soon as it enters the bloodstream, which is typically 15 – 20 minutes after consumption. You can expect to experience an increase in mental alertness, concentration and mental focus, while also experiencing a decrease in feelings of anxiety within this timeframe. Consistent use in conjunction with a sensible diet and workout regime will yield the full effects of L-Theanine within the first 2 weeks of use.

5.How Much Does It Cost?

Supplements containing an efficacious dose of L-Theanine range in price from $2.00 to $3.00 per serve, depending on the size and dosage, and the other ingredients included in the product.

Based on an average price of $2.50 per serve, and based on five serves per week, supplementing with L-Theanine will typically cost around $50 per month.
