L-Alpha glycerylphosphorylcholine is a natural choline compound found in the brain. It is also a parasympathomimetic acetylcholine precursor which has been investigated for its potential for the treatment of Alzheimer's disease and other dementias.
Alpha GPC is a natural compound that can also work well with other nootropics. Alpha GPC works fast and helps deliver choline to the brain and actually increases the production of acetylcholine along with cell membrane phospholipids. It's possible the compound may also increase the release of dopamine and calcium.
Alpha-GPC seems to be safe when used appropriately. It can cause side effects in some people including heartburn, headache, insomnia, dizziness, skin rash, and confusion.
