Phosphatidylserine is a phospholipid concentrated in neuronal membranes where it supports receptor function, neurotransmitter release, and signaling.

Alpha-GPC is a water-soluble phospholipid metabolite that delivers choline across the blood-brain barrier more efficiently than choline salts, which is why it anchors many focus and memory formulas and pre-workout blends.

Typical: 300–600 mg

Citicoline is a naturally occurring nucleotide that splits in the gut into choline and cytidine (converted to uridine), giving the brain both a choline source for acetylcholine and phosphatidylcholine and a uridine source for membrane synthesis.

Typical: 250–500 mg
