L theanine and caffeine are two natural ingredients that have been shown to have many benefits.

L theanine is an amino acid that is naturally found in green tea, while caffeine is a stimulant that is commonly found in coffee and tea.

Both of these ingredients work together to reduce stress, improve focus, increase creativity, and reduce anxiety.

1. Decreased stress

L-theanine and caffeine can help you relax.

Stress is a major cause of anxiety, and l theanine and caffeine may be able to help you feel less stressed.

If you have anxiety, it’s important that you avoid substances that could make your symptoms worse.

L-theanine has been shown to significantly reduce stress levels in people who are prone to high levels of stress or anxiety due to their work environment. 

The same study found that taking 200 mg of L-theanine before bedtime reduced cortisol levels overnight by 22%. 

2. Improved focus

If you’re looking to improve your focus, L-theanine and caffeine are two great choices.

L-theanine is an amino acid that has been shown to improve focus by increasing alpha brain waves, which help calm the mind.

Caffeine is a stimulant known for its ability to increase energy levels and improve mental alertness.

It does this by blocking the adenosine receptors in your brain so that dopamine can be released more easily, leading to increased motivation, alertness and attention span

3. Increased creativity

You may find that theanine and caffeine improve your creativity.

Research on the combination of these two ingredients shows that it can enhance creative thinking, attention, and memory.

If looking for a nootropic pairing to help with focus, creativity and stop procrastination, it maybe worth trying as a pair. 

4. Reduced Anxiety

Caffeine and theanine are natural stimulants that have been shown to have positive effects on our mood.

It is important to note, however, that these substances can also have the opposite effect.

Caffeine can increase anxiety in some people while l theanine reduces anxiety for most individuals. So if you get anxious from the feeling of caffeine, it is definitely worth testing l-theanine the next time you have your cup of coffee. 

One study found that when volunteers were given 200mg of l-theanine every day for one month, they experienced a significant reduction in their general stress levels as well as an improvement in their moods and overall sense of well-being.

5. Cognitive Nootropic

In addition to these health benefits, theanine and caffeine have been shown to have powerful cognitive effects.

Theanine has been shown to improve focus and concentration, reduce anxiety, and improve creativity.

Caffeine also appears to enhance attention and working memory by temporarily boosting dopamine levels in the brain—a neurotransmitter that's associated with motivation, pleasure seeking, reward-learning processes, decision-making skills, muscle control and physical movement (among other things).


L theanine and caffeine are two important ingredients that can be used in many different ways. While they may seem like simple chemicals at first, they have a lot of interesting benefits that you may not even realize until you try them out yourself.

A good starting place, is to try 100mg of l theanine with your next cup of coffee. Idealy take it in powered form. Or you can add in with your cup of coffee.
