L-Theanine

L-Theanine is an amino acid naturally present in Green Tea, but it doesn't share its stimulating effects.

While tea can be exciting, L-Theanine acts differently: it guides the mind towards a calmer, clearer, more composed state, without slowing down. It is this rare balance that makes it a key active for moments when one wishes to stay fully present, without inner turmoil.

L-Theanine and Green Tea: an essential difference

Green Tea contains several compounds: caffeine, but also L-Theanine.
Caffeine stimulates.
L-Theanine, however, does not excite.

Isolated, L-Theanine does not cause nervousness or energy spikes. It affects the quality of attention, not its speed.
That’s why it is studied to accompany calm and attentive mental states, very different from the “kick” effect of stimulants.

What research shows, concretely

Clinical studies conducted on adults have shown that L-Theanine can influence:

• attention,

• working memory,

• brain activity associated with a calm and attentive state (alpha waves).

These data suggest an action without exciting or sedative effects, compatible with situations where one wishes to remain alert, clear-minded, and available — even in social or festive contexts.

An active calm, not a slowdown

L-Theanine does not induce sleep. It does not “disconnect”.

It facilitates a form of inner calm that allows for listening, presence, and fluidity in exchanges.
This is what makes it particularly interesting in the evening, when one wants to truly be there, without tension or distraction.

A format designed for the moment

In Le Complément Grand Soir, L-Theanine is offered in the form of a liquid shot.
The liquid format promotes rapid assimilation, suitable for occasional, chosen use, when one feels the need.

 A synergy that makes sense

Combined with:

• Ginseng, which supports energy,

• and the Biotin – Zinc – Copper complex, which contributes to normal cognitive functions,

L-Theanine plays a balancing role: it allows energy to remain stable, composed, and comfortable.

 Why we love it at Pômesse Paris

We love L-Theanine because it:

• calms without extinguishing,

• clarifies without exciting,

• naturally balances energy,

• integrates perfectly into festive and chosen moments.

 To remember

• Amino acid naturally present in Green Tea

• Different from caffeine: non-exciting

• Associated with calm and clear attention

• No stimulating or sedative effect

• Ideal for moments of presence and sharing
