Evidence Level
Preliminary
0 Clinical Trials
3 Documented Benefits
1/5 Evidence Score

Alcolec® is a line of lecithin and phosphatidylcholine ingredients from American Lecithin Company, derived from soy or sunflower. Phosphatidylcholine is a building block of cell membranes and a source of choline. Published clinical data specifically for this ingredient as a supplement are limited.

Studied Dose Commonly a few hundred milligrams to grams per day.
Active Compound Lecithin enriched for phosphatidylcholine (a phospholipid and choline source), from soy or sunflower.

Benefits

Choline and brain support

Liver support

Phosphatidylcholine helps the liver package and export fat, supporting healthy liver fat metabolism.

Limited-evidence note

Phosphatidylcholine has a clear nutritional role, but dedicated published clinical trials of this specific lecithin ingredient are limited.

Mechanism of action

1

Membrane phospholipid

Phosphatidylcholine is a major structural phospholipid of cell membranes, supporting membrane integrity and function.

2

Choline delivery

Phosphatidylcholine is a gentle source of choline for acetylcholine synthesis and methylation support.
