Iced Matcha Green Tea

L-theanine Matcha has plenty, but what is it?

What is L-theanine?

L-theanine is an amino acid that is found in tea leaves, particularly in matcha green tea. It is a non-essential amino acid, which means that the body can produce it on its own. However, consuming L-theanine through food or supplements can provide a number of health benefits.

Benefits of L-theanine

L-theanine has been shown to have a number of benefits, including:

  • Improved cognitive function: L-theanine has been shown to improve cognitive function by increasing alpha wave activity in the brain. Alpha waves are associated with a relaxed state of alertness, which can improve focus and concentration.
  • Reduced stress and anxiety: L-theanine has also been shown to reduce stress and anxiety. It does this by increasing the production of GABA, a neurotransmitter that has calming effects.
  • Improved sleep quality: L-theanine can also help to improve sleep quality. It does this by promoting relaxation and reducing stress.
  • Boosted immunity: L-theanine has also been shown to boost the immune system. It does this by increasing the production of natural killer cells, which are a type of white blood cell that helps to fight infection.

How to get L-theanine

The best way to get L-theanine is through food or supplements. L-theanine is found in high concentrations in matcha green tea. You can also find L-theanine in supplements, which are available in both capsules and powder form.
