Benefit 4: Calming Effect

Contrary to common expectations tied to caffeine consumption, oolong tea manages to induce a calming effect, thanks to the presence of the amino acid L-theanine.  This unique combination offers relaxation without inducing drowsiness.

Therefore, oolong tea transforms into a calm bedtime drink, fostering a peaceful state of mind that supports the quest for a good night’s sleep.
