A little science, a lot of care.

At Celean, we didn’t just want to say “Trust us.”

We want you to understand what you’re taking… and why it might help you.

In this section, we simply explain each of the active ingredients in our syrups.

No complicated jargon. Just the essentials — so you can make an informed choice.

MELATONIN

Melatonin is a hormone naturally produced by your body, specifically by the pineal gland located in the brain.

Its production increases when it gets dark and helps regulate your sleep-wake cycle — also known as your biological clock or circadian rhythm.

As a supplement, melatonin is mainly used to improve sleep quality. It can be helpful for insomnia or to reset your internal clock in situations like jet lag, unusual work hours, or simply when your body needs a little nudge to slow down.

💤 It can help you:

Fall asleep more easily: By signaling to your body that it’s time to rest.

Improve the quality of your sleep: Many people report deeper, more restorative sleep.

Reset your biological clock: Especially useful when dealing with jet lag or routine changes.

L-THEANINE

L-Theanine is an amino acid naturally found in green and black tea leaves. Known for its relaxing effects, it’s often used to promote a sense of calm without causing drowsiness.

In short, L-Theanine may help:

• Encourage relaxation

• Reduce stress and anxiety

It works by influencing the levels of certain neurotransmitters in the brain — like serotonin and dopamine — which play a role in mood and relaxation. The result? A calming effect, without losing mental clarity.

GABA

GABA (gamma-aminobutyric acid) is a neurotransmitter naturally found in the brain.

It plays a key role in calming the excitability of the nervous system and promoting a state of relaxation.

In other words, it works like a natural brake for a racing mind — helping to slow mental chatter, relax the body, and create the right conditions for sleep.

Here’s what GABA supplements may help support:

• Promote relaxation and reduce stress

• Make it easier to fall asleep

• Provide a calming effect, especially useful during times of high tension

🌀 Note: The effectiveness of GABA can vary from one person to another. And since its ability to cross the blood-brain barrier may be limited, its benefits can also depend on the formulation and dosage used.

A quick but important note:

As with any supplement, if you're taking medication, living with a health condition, or simply have questions, we encourage you to speak with your doctor or pharmacist. It's always best to be well supported.

In short

Melatonin, GABA, and L-Theanine are three natural allies that gently work together to help you unwind, slow down, and support more restorative sleep.

At Celean, we chose them for their complementary effects — but above all, because they’re part of a simple, soothing, and delicious ritual… helping you care for yourself, one sip at a time.
