Alpha GPC 99% memory supplement

Alpha-GPC increases motivation in healthy volunteers

For those interested in the dietary supplement Alpha-GPC, a new study has shown that it increases motivation levels in healthy individuals. These findings provide further research into Alpha-GPC 99% and add to the body of evidence on memory retention and learning [1] [2] and membrane repair [3].

Before we dive deeper into this latest study, let's review what Alpha-GPC is, how it works, and why it's gaining in popularity.

Alpha-GPC Facts

  • Alpha-GPC is a natural choline compound found in the human brain.
  • It is the building block to acetylcholine, the chemical your brain releases during cognitive tasks.
  • When orally ingested, it leads to a relative spike in acetylcholine 1-3 hours later [1].
  • Alpha-GPC is recommended for anyone who works in a mentally strenuous role, students who need to study for exams, or anyone interested in increasing acetylcholine levels to support learning, memory retention, and focus [4].
  • Alpha-GPC can cross the blood-brain barrier. This barrier is a border of cells that protects your brain against circulating toxins.
  • According to the National Health and Nutrition Examination Survey (NHANES), up to 90% of Americans do not get enough choline in their diet [5].

The Study

Authors of the randomised, placebo-controlled study undertaken by Hiroshima University in Japan noted that “Alpha-GPC is a precursor of acetylcholine and can increase acetylcholine concentration in the brain.” [6] but the study was particularly interested in how Alpha GPC affected motivation.

Alpha GPC memory learning

A total of 39 healthy volunteers aged 22-59 consisting of 31 females and 8 males participated, reporting their emotional states 3 times a day, every day, for 2 weeks before treatment, and then 2 weeks after. The treatment group took 400mg of 99% Alpha GPC daily whilst the control group a cellulose capsule.

  • Alpha GPC showed a significant increase in motivation.
  • The placebo control group did not show any changes in motivation
  • Both groups saw a reduction in anxiety
  • The researchers observed no serious side effects in participants whilst also noting in the study that "previous clinical studies showed no serious side effects when human subjects took 1,200 mg/day for six months."
  • The researchers concluded that "Alpha-GPC increased motivation in human subjects without serious side effects, suggesting that Alpha-GPC supplementation has an increased effect on the motivation levels of healthy subjects” [6].
