However, the alpha-GPC form of choline quickly and efficiently moves choline into the brain where it’s used to form brain cell membranes and stimulate the growth of new brain cells.Alpha-GPC also increases levels of the neurotransmitters dopamine, serotonin, and GABA (gamma-aminobutyric acid), the neurotransmitter associated with relaxation. Signs of low GABA include being easily overstimulated, overwhelmed, and stressed out.
Alpha-GPC studies show it consistently improves memory and attention span in people of all ages, while warding off age-related mental decline.
A typical dose of alpha-GPC is 300 to 600 mg, but the ideal standard dose is yet to be determined.
In almost all studies on mental decline, participants were given 400 mg, three times a day.
Alpha-GPC Side Effects and Warnings
Alpha-GPC is generally considered safe, but possible side effects include headache, insomnia, dizziness, mental confusion, heartburn, and skin rash. Alpha-GPC supplements are derived from either soy or eggs, two of the most common food allergens, so be mindful if you have a known food allergy.
The only known drug interaction is with scopolamine, a drug often used for motion sickness and nausea following surgery.
