Alpha-GPC
What Is Alpha-GPC?
l-Alpha-glycerophophatidylcholine (GPC-choline, alpha-GPC)
is a water-soluble phospholipid and neurotransmitter
precursor naturally occurring in the body. Unlike most
membrane phospholipids, alpha-GPC is water-soluble
because it lacks the hydrophobic tail groups.
Uses For Alpha-GPC
• Memory And Cognitive Health:
Alpha-GPC passes
through the blood brain barrier providing a source of
choline for acetylcholine and phosphatidylcholine
biosynthesis. By supporting cell membrane fluidity and
integrity, phosphatidylcholine enhances healthy
neurotransmitter function and signal transduction.
Alpha-GPC may support healthy phospholipid turnover
in the brain, helping to counteract age-related cellular
breakdown of membrane phospholipids. Acetylcholine
is a key neurotransmitter in the brain supporting
memory and learning. Optimal phospholipid and
acetylcholine levels support cognitive, mental and
cerebrovascular health.*
• Growth Hormone Support:
Alpha-GPC has the ability to
potentiate growth hormone releasing hormone (GHRH),
thereby supporting healthy growth hormone (GH)
levels. The mechanism of support appears to involve
increased cholinergic tone.*
Source of Alpha-GPC
Alpha-GPC is derived from highly purified soy lecithin.
Vitamin C (ascorbyl palmitate) is derived from corn
dextrose fermentation. Hypo-allergenic plant fiber is
derived from pine cellulose. There is no detectable GMO
material in this product.
