A natural molecule full of benefits

Theanine is a natural molecule found mainly in certain varieties of tea. It has very interesting effects for athletes, hard workers and caffeine consumers.

Remarkable effects

One of L theanine’s best-known effects is its ability to improve cognitive function and attention, while promoting a calm state and reducing stress.

This is a unique benefit, as other nootropic molecules such as caffeine are often only stimulants. L theanine is capable of calming the nervous system.

More restful sleep

Theanine consumption is associated with deeper, more restful sleep. It also counteracts the negative effects of caffeine on sleep.

A nootropic that reduces stress

L-theanine is a unique molecule, as it is one of the few nootropics capable of both improving mental performance and reducing stress.

It’s a great ally for managing day-to-day life more effectively. Its effectiveness is increased tenfold if consumed at the same time as caffeine.

Qu’est ce que c’est ?

Pourquoi consommer un complément alimentaire plutôt que du thé ?

While tea leaf infusions are a weak but sufficient source of theanine, they have one major drawback: they are always accompanied by a variable dose of caffeine that cannot be measured.
