For a clear head in the morning
CDP-Choline
CDP-Choline · Citicoline (CDP-choline), a precursor of choline and brain phospholipids
The ingredient that supports the brain's overnight recovery.
250 mgin 1 Corti-Glow sachet
Helps with
Foggy head in the morningHard to focus after poor sleepA feeling of an “overloaded” mindSlow mental “waking up”
In plain language
Here's what it does, without complex words.
Citicoline breaks down in the body into choline and cytidine, two molecules the brain uses directly.
Choline is a building material for the membranes of brain cells (phospholipids).
It supports acetylcholine levels, the substance linked to memory and focus.
Natural source:
Citicoline (CDP-choline) is a compound the body produces naturally as part of choline metabolism. Dietary choline is found in eggs, liver, soy and fish, but for a stable dose in the sachet we use pure citicoline.
Why cdp-choline is in Corti-Glow
Every ingredient in Corti-Glow has a specific reason.
Overnight, the brain “clears out” the waste built up during the day and restores its capacity.
Citicoline supports exactly this nighttime recovery and the building of new cell membranes.
The result we're after is a clearer head the next morning, without the fog.
How it works on the body
Mechanism, step by step.
1Provides material for brain cells
Citicoline turns into choline and cytidine, which take part in building the membranes of brain cells.
2Supports acetylcholine
Choline is the raw material for acetylcholine, the substance linked to memory and concentration. More available raw material = steadier work from this system.
3Aids nighttime recovery
While you sleep, the brain “repairs” itself. Citicoline provides material for cell regeneration during the night.
4Result: a clearer morning
A better-recovered brain overnight means a clearer head and easier focus in the morning.
What to expect
Realistic timeframes, not promises.
The first days · CDP-Choline
A sense of a slightly clearer mental “wake-up” in the morning.
The first days
A sense of a slightly clearer mental “wake-up” in the morning.
1–2 weeks
Steadier concentration through the day, especially after shorter sleep.
3–4 weeks
Less of an “overloaded” mind. A clear head more often.
How it works with the other ingredients
7 ingredients in Corti-Glow. Here's the mechanism why they work together.
Not just 7 supplements in one box. Every combination has a specific mechanism, here's why the formula is what it is.
Combination
CDP-Choline + L-Theanine
+ L-Theanine · 200 mg
For calm focus without drowsiness
Mechanism
L-Theanine calms the mind in the evening and creates a state of calm focus. Citicoline supports the brain's overnight recovery. In the evening, a calmer mind; in the morning, a clearer head.
End benefit
A calm evening + clearer thinking the next day.

Participants
95 older volunteers
Dosage
1000 mg citicoline daily, 3 months
Result: Improved memory in older adults with mild memory decline, especially for words and logical sequences.
Why this exact dose in Corti-Glow
250 mg, specific, not random.
- →250 mg is the dose studied for attention and concentration in healthy people (McGlade 2012).
- →Enough for daily evening support of brain recovery, without overdosing.
- →Pure citicoline (CDP-choline), a stable and convenient form of choline.

Frequently asked questions
About cdp-choline.
Is this a stimulant? Will it keep me awake?+
No. Citicoline is not a stimulant like caffeine. It doesn't force energy up, it supports the brain's overnight recovery so that the morning head is clearer.
Why exactly 250 mg?+
250 mg is the dose used in attention and concentration studies in healthy people (McGlade 2012). It's enough for daily maintenance, without needing a higher “clinical” dose.
What's the difference from ordinary choline?+
Citicoline (CDP-choline) carries both choline and cytidine, both useful for brain cells. That makes it a more convenient form than standalone choline for evening use.
