Bioavailable source of Choline
Supports Brain Function**
Alpha GPC is a natural physiological precursor to acetyl-choline, a neurotransmitter that is involved in memory and other cognitive functions. ** Alpha GPC is more bioavailable than other forms of choline. In the brain and other neural tissues, Alph GPC becomes a constituent of cell membranes. Supplementation with Alpha GPC may increase the brain's synthesis of acetyl-choline. ** In this way, it helps to support cognitive function.**
