L-theanine and caffeine are two substances that are often consumed together. L-theanine is an amino acid found in green tea leaves, and caffeine is a naturally occurring stimulant found in coffee beans, tea leaves, and other sources. When consumed together, these two substances have been shown to have a number of potential benefits.

In this blog post, we will explore the benefits of l-theanine when paired with caffeine.

Improved Focus and Concentration

One of the most well-known benefits of caffeine is its ability to improve focus and concentration. However, some people experience negative side effects of caffeine, such as jitters or anxiety. This is where l-theanine can come in. Studies have shown that l-theanine can help to reduce the negative effects of caffeine while still maintaining its positive effects on focus and concentration. L-theanine is thought to do this by promoting a state of relaxation without causing drowsiness.  Products like Rogue Energy pair 200mg of l-theanine with 175mg of caffeine for a smooth, non-jittery energy and focus boost.

Reduced Anxiety

As mentioned, some people may experience anxiety or jitters when consuming caffeine. L-theanine has been shown to have a calming effect, which may help to counteract these negative effects. A study published in the Journal of Clinical Psychiatry found that l-theanine reduced anxiety symptoms in patients with schizophrenia.

Improved Sleep Quality

While caffeine can improve focus and energy levels, it can also interfere with sleep. L-theanine has been shown to have a relaxing effect and may improve sleep quality when consumed before bed. In a study published in the Journal of Clinical Sleep Medicine, participants who consumed a combination of l-theanine and caffeine before bed had improved sleep quality compared to those who consumed a placebo.

Reduced Blood Pressure

Both caffeine and l-theanine have been shown to have a positive effect on blood pressure. However, when consumed together, they may have an even greater effect. A study published in the journal Biological Psychology found that a combination of caffeine and l-theanine reduced blood pressure.
