When to Take L Theanine: Morning or Night?

If you've been looking into supplements to support your mental health and overall wellness, you've likely come across L-theanine. This naturally-occurring amino acid, primarily found in green tea, has become well-recognized for its potential benefits on cognitive function, stress reduction, and sleep quality. 

But as with most supplements, timing matters. When to take L theanine - morning or night - influences the way in which it can enhance your life.

So, should you take it early in the morning to offer a boost of energy as you head out for the day? Or, should you take it in the evening to help you wind down from a stressful day and get a good night’s rest?

Ultimately, there is no one size fits all answer. It comes down to your unique health goals. That’s why we’ve decided to have a conversation on timing today to help you get the most out of your supplement. Beyond finding the best time to take L theanine, we’ll offer other insights on maximizing the benefits of this powerful amino acid.

Does it Matter When You Take Your L Theanine Supplement?

First things first, does it really matter when you take this supplement? It sure does - because if you take it at the wrong time, you could end up with the opposite intended effect. 

For example, if you’re taking L theanine for an energy boost, it wouldn’t make much sense to take it at night - would it? Conversely, attempting to improve your sleep cycle by taking an L theanine supplement in the morning may not offer much benefit when bedtime rolls around.

That being said, let’s look at why you need to find the best time to take L theanine.

Impact on Sleep Patterns

When you take your L-theanine supplement can have a significant influence on your sleep patterns. L-theanine is often celebrated for its sleep-enhancing properties, primarily its ability to promote relaxation and reduce insomnia. 

How does it do this? By boosting the levels of gamma-aminobutyric acid (GABA), serotonin, and dopamine in the brain - neurotransmitters that play key roles in mood regulation, sleep, and relaxation. By increasing these levels, L-theanine can help prepare your body for a good night's sleep.

However, timing is crucial. Taking L-theanine too close to bedtime may result in a very restful sleep, but it could potentially make waking up the next morning a bit more challenging. On the flip side, taking it too early in the evening may result in its effects wearing off before you're ready to turn in for the night.

Effects on Daytime Alertness and Stress

L-theanine isn't just for bedtime, though. When taken during the day, L-theanine can significantly enhance your alertness and cognitive function. 

This amino acid has been shown to boost alpha brain wave activity, promoting a state of wakeful relaxation - that means you're calm, but alert and focused, making it perfect for handling a stressful workday or studying for a big test.

Furthermore, L-theanine's stress-reducing properties are especially beneficial during the day. By modulating the body's physiological response to stress, L-theanine can help you keep your cool in stressful situations, reducing both mental and physical symptoms of stress.


So, with this understanding of the significance of when to take L theanine supplements, let’s now take a look at some of the factors that will influence your ideal dosage window.

Factors Affecting When to Take L Theanine Supplement

Determining the right time to take your L-theanine supplement isn't a simple case of morning or night. Several factors can influence the efficacy of the supplement and how it interacts with your body. These include health goals, other medications/supplements, and your unique sleep-wake cycle.

Your Health Goals

When to take L-theanine supplement significantly depends on your individual health objectives. If you're trying to enhance your focus during the day, taking L-theanine in the morning or early afternoon may be the way to go. 

On the other hand, if you're looking to improve your sleep quality, consider taking it in the evening, a few hours before bedtime. As we’ve mentioned, though, this is just one of three important considerations…

Other Medications and Supplements

The specific time of day when you take L-theanine may also depend on other medications and supplements you're currently taking. If you're taking stimulants or medications that could interfere with your sleep, it may be beneficial to take L-theanine in the evening to help counteract these effects. 

Alternatively, if you're using sleep aids or other sedatives, consider taking L-theanine during the day to prevent potential excessive drowsiness. Always consult your healthcare provider before starting any new supplement regimen, especially if you are already taking other medications.

Your Sleep-Wake Cycle

Another crucial factor in determining the best time to take L-theanine is your sleep-wake cycle, also known as your circadian rhythm. 

If you're an early bird who wakes up at the crack of dawn, taking L-theanine in the early morning can help enhance your alertness and cognitive function throughout the day. 

Night owls, however, may find that taking L-theanine in the late afternoon or early evening can help balance their energy levels, reduce evening stress, and prepare their bodies for restful sleep. It's all about finding a rhythm that works for you and aligns with your lifestyle and natural sleep patterns. 

Our Advice on When to Take L Theanine: Morning or Night

So, when should you take L theanine? If you aren't clear on the best time to take L theanine by now, we’ll give you our advice on the matter below. 

While this topic can easily become overcomplicated, we’re going to simplify it into two buckets: when to take L theanine for insomnia and when to take it for cognitive function/focus.

For Enhanced Focus and Cognitive Function: Morning or Afternoon?

If your primary goal is to boost your cognitive functions and enhance your focus during the day, then you may want to consider taking your L-theanine supplement in the morning or early afternoon. 

Here's why: L-theanine promotes the production of alpha brain waves which are associated with states of "wakeful relaxation”. That's the state of mind you experience when meditating, being creatively engaged, or daydreaming.

This makes L-theanine a perfect ally for those mornings or afternoons when you need to be at your best, whether it's an important meeting, an exam, or a creative project. 

By supporting your natural brain function, it can help you achieve a state of relaxed focus without the jittery side effects of other stimulants. 

However, if you're pairing L-theanine with caffeine, you'd ideally want to avoid taking it late in the afternoon to avoid interfering with your sleep.

For Improved Sleep and Relaxation: Evening or Night?

On the other hand, if your goal is to improve the quality of your sleep and promote relaxation, taking L-theanine in the evening could be the right choice. 

While L-theanine doesn’t act as a sedative, it does help to create a sense of calm and balance in the mind, reducing feelings of stress and anxiety. This can help you unwind from the day and prepare your body for a good night's sleep.

In the evening, L-theanine’s support for the production of alpha brain waves can help ease the transition between the alert state needed for your daily activities and the restful state desired for sleep. 

Additionally, L-theanine can support the production of GABA, a neurotransmitter that plays a key role in promoting deep, restorative sleep.

Wait - How Does it Act as a Boost in the Morning and a Sleep Enhancer at Night?

We know many who are discovering the versatile power of L-theanine are curious…how does it work so well to improve sleep quality at night, yet give you a cognitive boost in morning? Seems fairly contradictory, we’ll admit. But that’s part of the magic and allure of this incredible compound.

The fascinating thing about L-theanine is that it doesn't directly stimulate or sedate the body. Instead, it promotes a state of "relaxed alertness". This means it can help improve focus and cognitive function, without causing the jittery feeling associated with stimulants like caffeine.

During the day, this relaxed alertness can translate to better focus and productivity. When combined with the natural energizing effects of daylight and the active pace of a typical morning, L-theanine can help keep your mind sharp and clear, enhancing your ability to tackle the day's tasks.

At night, on the other hand, L-theanine's calming effects can be especially beneficial. Even though it doesn't act as a sedative, it can help to promote relaxation and reduce stress, preparing your body for sleep. If you've ever laid awake at night with your mind racing from the day's stresses, L-theanine can help by soothing your nervous system and promoting a more restful state.

All of this is to say that no matter what your current lifestyle and health situation entails, there is a fair chance you could benefit from adding this supplement to your regimen. And, now that we’ve fully unpacked the best time to take L theanine, let’s offer a few more tips before wrapping our conversation up.

More Tips on Maximizing Your L Theanine Supplement

Taking L-theanine is a simple and effective step towards better mental health, improved focus, and quality rest. However, beyond knowing the best time to take L theanine, there are a few extra things to consider to ensure you're getting the most out of your supplement.

Ensuring Optimal Absorption: The Role of Diet

L-theanine is a water-soluble supplement, meaning it does not need to be taken with food to be properly absorbed. However, the timing of meals might play a role in how L-theanine works for you. 

If you find taking L-theanine on an empty stomach causes discomfort, try taking it with a light snack. Conversely, if you find its effects less pronounced when taken with a large meal, take it in between meals.

The Importance of Consistent Use: Patience is Key

As with many supplements, patience and consistency are essential when taking L-theanine. Its effects can be subtle, and while some people notice changes immediately, others may need several weeks of consistent use to experience the full benefits. 

To make this part of your routine, consider setting a reminder or pairing it with a daily habit, such as brushing your teeth. The more consistent you are in loading your body’s stores with L theanine, the more effective it’ll be.
