Destress with These Soothing L-Theanine Drinks

According to neuroscientist Dr. Sara, “L-theanine promotes relaxation and focus by increasing alpha brain waves.”

Have you ever felt too wired to sleep or focus? Like your thoughts race nonstop on caffeine?

I used to constantly battle the jitters until discovering an amino acid called L-theanine.

When I first tried the Japanese Green Tea with added L-theanine, it was a game changer.

The L-theanine smoothed out the caffeine spike, helping me chill out and enhance concentration.

I couldn’t believe a simple nootropic supplement could make such a difference.

Let me share how L-theanine drinks can help you find the same focus and tranquility I did.

Have you heard of L-theanine drinks but aren’t sure what exactly they are? 

L-theanine drinks are beverages that contain the amino acid L-theanine as a key ingredient.

Let’s break down what L-theanine is and how it shows up in drinks.

L-theanine is a unique amino acid most commonly found in tea leaves.

It is especially prevalent in green tea and white tea.

When tea leaves are steeped in hot water, the L-theanine is extracted from the leaves into the tea.

Green tea naturally contains between 20-50 mg of L-theanine per 8 oz cup.

Beyond traditional tea, some companies now isolate L-theanine from tea leaves and add it to other beverages to create L-theanine drinks.

This allows people to easily obtain the relaxation benefits of L-theanine without having to drink tea.

Common L-theanine drinks include:

  • L-Theanine water: Plain water infused with L-theanine powder or extract for a calming beverage option.
  • L-Theanine sparkling water: Carbonated water with added L-theanine gives it a fizzy taste while still providing relaxation effects.
  • L-Theanine lemonade: A refreshing lemonade drink made sweeter with L-theanine instead of sugar.
  • RTD L-theanine teas: Ready-to-drink iced teas with added L-theanine, like green tea.

So in summary, L-theanine drinks are any beverages that specifically list L-theanine as an ingredient and are designed to deliver this calming amino acid easily through various drink formats.

They provide an easy way to reap the benefits of L-theanine without having to brew tea.

Benefits of L-Theanine Drinks

L-Theanine Drinks

L-theanine has POTENTIAL BENEFITS for mental state AND SLEEP QUALITY. 

Here are some top ways L-THEANINE drinks CAN HELP IMPROVE your health:

Stress Relief and Relaxation

L-theanine INTERACTS WITH alpha waves IN THE BRAIN to PRODUCE A RELAXED mental state WITHOUT DROWSINESS. Some research shows L-theanine MAY HELP REDUCE stress and ANXIETY.

Table 1: Effects of L-Theanine on Mental State

Mental Effect
Supporting Research
Relaxation without drowsiness
L-theanine increases alpha brain waves which produces a relaxed and alert state of mind. A 2002 study found it improved mood and reduced anger in study participants.
Reduced stress and anxiety
Several studies link L-theanine to reduced stress hormones like cortisol and decreased physiological stress responses.

Improved Sleep Quality

Consuming L-THEANINE before bed MAY HELP PEOPLE FALL ASLEEP faster and INCREASE TIME SPENT in REM sleep, vital for feeling rested.

According to latest news, L-THEANINE helps induce calming chemical GABA for better sleep.

L-theanine drinks like tea are NATURALLY GLUTEN-FREE and SUGAR-FREE alternatives to caffeinated drinks.

Unlike energy drinks, they don’t cause side effects like “caffeine crashes” or jitters.

Overall, emerging research suggests L-THEANINE can SIGNIFICANTLY HELP IMPROVE mental health and sleep.

Drinking one can provide stress relief and relaxation all in one fuss-free beverage!

Pairing and Timing:

Exactly WHEN AND HOW you consume L-THEANINE can influence its effects. Some ways to maximize the BENEFITS include:

  • Pair L-theanine drinks with coffee. The COMBINATION HELPS INCREASE alertness while reducing anxiety better than either alone.
  • Drink 1-2 hours before bed. Consuming L-THEANINE earlier allows it to SUPPORT RELAXATION and IMPROVE SLEEP as bedtime nears.
  • Consider timing. Taking L-THEANINE in tandem with stress can help REDUCE STRESS AND ANXIETY by lowering cortisol levels.

However, responses vary, so EXPERIMENT WITH TIMING.

Additional research on long-term cognitive effects is also needed since most studies use it short-term.

Proper pairing and timing can help L-theanine live up to its POTENTIAL.

Sources of L-Theanine

The top dietary sources of L-THEANINE include (2):

  • Green TEA – Contains about 30mg per 8oz cup on average. Try matcha powder too.
  • Black TEA – Provides smaller amounts around 5-10mg per cup compared to green.
  • White TEA – Another good plant source with 20mg per cup.

While tea is the best natural source, THOSE NOT DRINKING MUCH TEA daily may consider an L-THEANINE supplement.

Choose ones containing at least 100mg per serving for mental benefits.

Both supplements and foods containing L-THEANINE support relaxation as part of a HEALTHY lifestyle.

Usage and Benefits

L-THEANINE supplements are often recommended as a NATURAL WAY to help with stress, anxiety, and sleep issues.

Some potential benefits include:

Relief from Anxiety and Stress

Emerging evidence suggests L-THEANINE MAY HELP REDUCE ANXIETY and lower stress levels.

A Japanese study in over 1,800 people found daily green tea consumption (high in L-theanine) reduced risks of depression and anxiety later in life.

L-theanine has tripled patents filed since 2018 according to the WHO based on its nootropic properties.

Improvements to Sleep Quality

Research involving healthy adults shows L-THEANINE INCREASES Alpha BRAIN WAVES important for relaxation while also promoting deeper REM sleep vital for restoration overnight.

Doses around 100-200mg before bed may help fall asleep faster for some individuals.

Potential Impact on Brain Function

How exactly L-THEANINE WORKS IN THE BRAIN is still under investigation.

More long-term human trials are needed to fully understand its cognitive effects and benefits for brain-related conditions like Alzheimer’s disease.

Overall, emerging evidence hints at wide-ranging effects through interaction with neurotransmitters.

Proper research is key to substantiating these BENEFITS.

Future studies will provide deeper insight into L-theanine’s range of potential mental health applications for reducing stress, anxiety, depression, and more.
