About Alpha-GPC Capsules

  • Supplemental for cognitive health*
  • Benefits memory, verbal recal and learning*
  • Promotes physical power output*
  • Tested for dosage and purity

Why Alpha-GPC 50%?

Pure Alpha-GPC is very hygroscopic and absorbs moisture from the air, turning pure Alpha-GPC into a paste if it sits long enough. This is not ideal for supplementation, so we provide a 50% powder. It is manufactured alongside silicon dioxide, which eliminates the hygroscopic problems, and also prevents the 50% formulation from hardening when exposed to air.

What is Alpha-GPC?

Alpha-GPC (Alpha-Glycerophosphocholine) is a precursor to acetylcholine and Phosphatidylcholine. This choline source is naturally occurring in red meats, eggs, and soy. Unfortunately, relying on diet alone does not yield enough Alpha-GPC to experience maximum benefits.

Alpha GPC Powder VS Capsules

Both capsules and powder will provide the same excellent benefits; however, capsules make supplementation much easier and convenient. Each capsule contains the premeasured effective dose of Alpha-GPC so no scale is required.

Alpha-GPC as a Nootropic


Protein Kinase C (PKC) is associated with short and long-term memory. Supplementing with Alpha-GPC promotes PKC activation, thus supplementing overall memory function.* [5,6]


Studies show Alpha-GPC intake promotes serotonin and dopamine concentrations. [1,2] Serotonin and dopamine are neurotransmitters responsible for mood, memory, learning, social behavior, and more. Alpha GPC also encourages GABA production, which is a neurotransmitter that promotes calmness.* [3]


One study showed that taking Alpha-GPC with phosphatidylserine benefits reaction time, focus, and alertness in healthy college students. This study also demonstrated that these effects are being observed after exercise.* [4]

Alpha-GPC and Bodybuilding

Power Output

Alpha GPC is now becoming popular in bodybuilding due to its effects as a pre-workout supplement. Studies show Alpha-GPC caused a 14% increase in power output compared to a placebo.* [7] 

Alpha GPC has also been shown to be beneficial in maintaining a healthy body composition.* [8]

Stacking Alpha-GPC

Alpha-GPC works well with pre-workout products. This supplement will supplement healthy focus and power to allow for a stronger and more effective workout.*

Alpha-GPC Dosage

The recommended dosage of Alpha-GPC is two capsules once daily. Each capsule contains 150mg of Alpha-GPC. For best results, take Alpha-GPC with a fatty acid like CLA or Fish Oil.

Synonyms: L-Alpha glycerylphosphorylcholin, Alpha glycerylphosphorylcholine, Choline Alphoscerate, glycerophosphocholine
