L-Theanine: The Calm Part of Your Cup of Tea

Ever noticed that green tea feels different from coffee? Part of the reason is L-theanine.

What it is

L-theanine is an amino acid found naturally in tea leaves. Your body doesn't use it to build protein. That's why it's often talked about on its own.

Why people like it

Many people describe it as calm without feeling sleepy. Researchers have been studying it for years, mostly in small trials, so the evidence is still developing. That's why we won't promise effects that haven't been confirmed.

How people use it

Some take it with their morning coffee. Others make it part of their evening routine. If you're trying it for the first time, start with one new product at a time so you can tell what suits you.

Where you'll find it at BKM

Tranquil, our evening blend, combines L-theanine with magnesium, GABA, ashwagandha root and chamomile. Magnesium contributes to normal functioning of the nervous system and normal muscle function.

Harmonized, developed for women, also contains L-theanine, along with magnesium, ashwagandha root, essential amino acids and lactic acid bacteria.

A simple routine to try

  1. Set a regular bedtime.
  2. Dim the lights an hour before.
  3. Make tea or take your evening supplement.
  4. Read or stretch instead of scrolling.

In short

L-theanine is a simple ingredient with a long history in tea. It works best as one part of a good routine, not as a shortcut.

Food supplements should not replace a varied, balanced diet and a healthy lifestyle. Talk to a healthcare professional if you're pregnant, breastfeeding or taking medication.
