Alpha GPC (L-alpha glycerylphosphorylcholine) helps human health by boosting brain levels of acetylcholine, supporting cellular membrane integrity, and potentially enhancing physical power output. It is widely used to support cognitive function, athletic performance, and age-related memory decline.

alpha GPC has demonstrated significant efficacy in treating neurodegenerative diseases such as cerebral ischemic stroke, Alzheimer’s disease, and multi-infarct dementia, with few side effects and good tolerability. As early as 1990, Italy was the first to develop GPC active pharmaceutical ingredients and finished dosage forms. Over the past few decades, Europe has been using GPC to treat Alzheimer’s disease and stroke.

Years of clinical research have shown that GPC not only enhances human memory and cognition, but also exhibits significant therapeutic effects on cerebral circulation decline and senile dementia. Therefore, it is known as the “anti-aging nutrient” for the brain, and there are currently basic products available as dietary supplements.
As people age, their perception gradually declines.

It can also induce neurodegenerative conditions such as vascular dementia and Alzheimer’s disease. However, when the levels of neurotransmitters (used for signal transmission in the central nervous system) such as “acetylcholine” and “phosphatidylcholine” increase in the body, the damage to human brain cell membranes will be improved, which is beneficial to the health of cerebral blood vessels, thereby improving cognitive function and symptoms of senile dementia.

Since GPC is a water-soluble substance that can cross the blood-brain barrier and enter the brain, it provides the raw material choline (a biosynthetic precursor of acetylcholine and phosphatidylcholine) for the synthesis of acetylcholine and phosphatidylcholine (PC).

Choline is a vitamin-like nutrient that is crucial for health, especially as a source of methyl groups for healthy gene regulation (epigenetics). Choline is also used to produce acetylcholine (ACh), which is not only the most abundant chemical transmitter in the brain but also a universal messenger substance serving other organs.

They can affect the transmission of chemical information in the brain and help brain cells store and retrieve information, serving as important nutrients for maintaining normal memory, reaction, and healthy emotions in the brain.

In addition to synthesizing neurotransmitters, GPC can also promote the secretion of growth hormone, which is a major hormone that promotes tissue maintenance and tissue regeneration.

The large family of phospholipids is studied in high school biology. Our cell membranes are composed of phospholipid bilayers, and neurons are no exception.

Phosphatidylcholine (PC), phosphatidylserine (PS), water-soluble GPC, and glycerophosphatidylserine (GPS) all belong to phospholipid substances that can provide acetylcholine.

Providing neurons with sufficient phospholipid substances is beneficial for the increase of basic neuronal structures (such as synapses), and simultaneously enhances the functions related to these basic structures (such as neurotransmitter synthesis) as well as the functions of special structures derived from these basic structures.

The dosage study of alpha GPC, through external supplementation, namely oral administration or intravenous injection, can be absorbed at the sites of the small intestine and intravenous injection, and then enter various organs such as the brain, liver, and kidneys through blood circulation to exert its effect.

The commonly used choline salts in dietary supplements only temporarily elevate blood choline levels, whereas alpha GPC not only rapidly increases blood choline levels but also maintains them elevated for up to 10 hours.

Most clinical studies have employed a dosage of 1200mg per day (administered in three divided doses of 400mg each), demonstrating cognitive benefits. However, high doses may be suitable only for patients with dementia. Therefore, it is advisable to commence with 300mg, assess the efficacy, and then increase the dosage if necessary.
