Amino Acid L-Theanine And Caffeine: Is It A Perfect Morning Combo?

Could amino acid l-theanine and caffeine be a good morning combo? This could change your breakfast foods to include coffee or tea with the amino acid. What are the benefits?

Amino acid l-theanine

Are you looking for a way to spruce up your morning cup of coffee or tea? If so, then one possibility is amino acid l-theanine and coffee. The first evidence of humans drinking coffee was the 1400s in Yemen. It’s believed that L-theanine could provide benefits like reducing caffeine’s jitters while amping up the benefits. If it works it could be Coffee 2.0. If there’s one complaint that people have about coffee/tea is that drinking several cups can cause them to feel anxious or have the jitters. This can make it tough to get through the day and could cause some issues for people with heart conditions.

L-theanine is one of the 20 amino acids in the human body. It’s found in foods like tea and is sometimes prescribed for treating mental conditions like stress and anxiety. This helps to explain why it might be a good pairing with coffee, tea, and other natural caffeinated drinks. This amino acid is an “essential” one so it’s one we have to consume from food/supplements anyway since the body doesn’t produce EAAs. Like other EAAs it’s higher in some foods than others. However, another option to boost your intake of EAAs is through.

What Exactly Is L-theanine?

Theanine is one of the essential amino acids (EAAs) that humans get from food/supplements. It’s found in various foods like tea leaves of green/black varieties and some mushrooms. The structure of theanine is similar to another amino acid known as glutamic acid, which is another one that’s critical for normal body functioning.

You can also get this amino acid through supplements. That includes tablet/pill form in various physical and online drugstores.

Studies show that L-theanine can provide several health benefits. One interesting one related to its use with caffeine is for relaxation. A key benefit is that it doesn’t provide drowsiness, which is a plus. Many people take L-theanine to reduce stress/anxiety and unwind after a tough day at work, school, or home.

It’s important to know the basics of this amino acid. That includes what it’s all about, benefits, and possible risks/side-effects.

Sometimes this amino is just known as “theanine.” It’s claimed this amino acid can provide various benefits related to:

  • Muscle strength
  • Blood pressure
  • Anxiety
  • Heart health
  • Immune system  

More research is needed for these possible benefits but some studies show that the amino acid could help in these areas.

During the 1900s’ first half scientists discovered that green tea had a high amount of L-theanine. This has resulted in the amino acid being added to different products like gum, soft drinks, and chocolates. It helps people to feel relaxed yet not drowsy.

It’s ideal to consume L-theanine in the morning since it’s easier to control levels while not affecting focus. This would make it a potentially good option for morning coffee/tea.

It’s worth noting that many of the possible benefits of the amino acid are the same as those found in green/black tea. So L-theanine with coffee could provide the best of both worlds. You’d get the physical/mental boost from the caffeine while enjoying the calming effect of green tea.

Amino Acid L-theanine + Coffee

It’s been suggested that this would be a good pairing instead of a regular cup of Joe. What’s the big deal? It’s no secret that black coffee is sky-high in caffeine. Green tea is also high but the amount is still lower than brewed coffee.

Studies show that natural caffeine sources can provide several health benefits. They include energy bursts and less brain fog. There are other possible benefits like lower blood pressure, cholesterol, and blood sugar.

However, anyone who’s had multiple cups of black coffee in the morning knows that it can cause some unwanted side-effects including anxiety and jitters. One way to deal with this issue is to add some real milk or cream. This will help to neutralize the acidity and caffeine’s effects.

Another possible option is L-theanine. They probably won’t have this option at your local coffee shop so you’d have to buy an L-theanine supplement to add to your mud, java, or go-juice. However, if the combo provides the claimed benefits then it would be worth toting a can of aminos with you during the day.

The results are that the caffeine’s benefits are boosted while the jitters are reduced. That’s because of the amino acid’s calming effects. However, it seems to amp up the caffeine’s benefits for the mind and body.

The Theanine seems to boost the drinker’s energy/alertness and mental focus. These are some of the main reasons why people drink 1+ cups of coffee in the morning.

The big benefit is it reduces the side-effects of lots of coffee. That’s because the amino can cause a calming/relaxing effect on people. That’s the opposite effect that caffeine produces.

Theanine affects the human brain in various ways. It is believed to calm nerves and boost creativity. It also boosts levels of the GABA hormone. These are related to focus and calmness.

Top Benefits of L-Theanine


It is one of the main factors that help to reduce jitters when you pair coffee and theanine. Consider that while green tea is high-caffeine it also has chemical compounds that help people to relax and sleep better at nighttime.

Studies show that black/green tea might help people to feel more relaxed by lowering the resting heart rate of the person. It could help you to feel more relaxed when combining coffee and tea-based amino acid.

Better Sleep 

Many studies show that amino acid can help people relax, doze off, and sleep better at bedtime. It seems to be linked to the effects of the amino acid on the brain’s sleep-related chemicals. Keep in mind this effect will be reduced when combined with caffeine so you won’t have to worry about being drowsy all day.

Weight Loss 

Studies show that the L-theanine could have the same weight-loss benefits when consumed by itself or with another substance like coffee, for example. This could help you lose weight and reach your weight loss goals. The two substances work together to help you shed pounds.

Brain Function

Studies show that theanine also might help to boost brain function. A 2016 study showed that it was critical for improving how well people’s brain cells worked. This was due to the ability to protect brain cells. The benefits might be boosted when combined with the mental benefits of caffeine.

Mental Focus

This is one of the benefits of caffeine as well, so it explains why it amps up coffee’s ability to keep you mentally sharp. A 2012 study showed that consuming 100mg of the amino acid caused fewer errors when doing mental tasks versus those who took a fake pill. The study interesting showed that caffeine produced more mental focused when combined with amino acid l-theanine.
