For a clear head in the morning
Choline Bitartrate · Choline bitartrate — a form of choline, an essential nutrient
The ingredient that supports normal nervous system function.
Helps with
In plain language
Choline is a vitamin-like essential nutrient the body cannot produce in sufficient quantities on its own.
It is a building block of phosphatidylcholine — a compound that forms the membranes of brain cells.
Choline supports acetylcholine levels, the neurotransmitter linked to memory, concentration, and focus.
Natural source:
Choline is an essential nutrient found in eggs, liver, soy and fish. The body produces small amounts, but not enough for optimal function. Choline bitartrate is a stable, water-soluble form — ideal for sachets.
Why choline bitartrate is in Corti-Glow
Overnight, the brain “clears out” the waste built up during the day and restores its capacity.
Choline bitartrate is a stable, water-soluble form — ideal for sachets, gentle on the stomach.
The result we're after is a clearer head the next morning, without the fog.
How it works on the body
Provides material for brain cells
Choline participates in the synthesis of phosphatidylcholine — the main component of brain cell membranes.
Supports nervous system function
Choline is the precursor to acetylcholine, the neurotransmitter linked to memory and concentration.
Aids nighttime recovery
While you sleep, the brain repairs itself. Choline provides material for cell membrane maintenance during the night.
Result: a clearer morning
Well-maintained brain cells mean an easier mental wake-up in the morning.
