Best choline supplement for brain health? Alpha GPC reviewed
filter
Key points
- Memory & learning are supported by an essential brain chemical acetylcholine
- Protein-rich foods increase choline, the building block of acetylcholine
- Alpha GPC is the most effective & potent natural choline supplement
Choline is an important nutrient that was granted the status of an essential nutrient in 1998 by the US Institute of Medicine. The importance of choline was recognised due to its function in the liver, brain and body cells starting from pregnancy and infancy up until old age. In the brain, choline is used to produce the chemical involved in memory, learning and attention, called acetylcholine. The US recommended intake for adults is 550 mg/day for males and 425 mg/day for non-pregnant females. The European guidelines recommended a choline intake of 400 mg/day for adults in 2016. Wondering which is the best choline supplement to take and what is the best form of choline? You’ve come to the right place.
Which food has the most choline?
In short, protein-rich foods. Though your body can produce small amounts, choline must be obtained from dietary intake to meet the body’s needs to ensure optimum functioning. Foods high in choline include[1 Trusted Source My Food Data 3rd-party source Foods Highest in Choline ] :

Cooking can reduce choline content in some foods[2 Trusted Source 2020 - Nutrients Systematic and meta-analysis The Relationship between Choline Bioavailability from Diet, Intestinal Microbiota Composition, and Its Modulation of Human Diseases ] . For example, 30% choline is lost when chicken is roasted[3 Trusted Source 2007 - The FASEB Journal Animal study Determination of Cooking Yields and Nutrient Retention Factors of Choline in Meat Products ] . In foods, choline is found in many forms and different forms are absorbed at different rates[4 Trusted Source 2019 - Journal of Dietary Supplements Systematic and meta-analysis Choline: The Neurocognitive Essential Nutrient of Interest to Obstetricians and Gynecologists ] .
Is Alpha GPC the best form of choline?
Yes, Alpha GPC is the most potent form of choline. Choline can be consumed as a supplement. Those who have low choline intake in their diet can benefit from supplementation. Wondering is Alpha GPC better than choline? Alpha GPC is the best source of choline currently available. This is due to its high choline content (41% of choline by weight) and ability to freely pass into the brain. brain feed has created the world’s 1st 500mg Alpha GPC capsule containing 99% Alpha GPC* (the purest form of Alpha GPC).
What does Alpha GPC choline do?
Levels of the memory chemical acetylcholine boost when you ingest Alpha GPC. Acetylcholine is then released when you’re performing cognitive tasks, such as memory retention and learning. Alpha GPC naturally occurs in the brain; however, supplementation helps keep the levels of acetylcholine more in check. Studies show that boosting choline levels can help restore the bioavailability of acetylcholine[5 Trusted Source 1986 - Il Farmaco; Edizione Scientifica Animal study Changes in the interaction between CNS cholinergic and dopaminergic neurons induced by L-alpha-glycerylphosphorylcholine, a cholinomimetic drug ] , [6 Trusted Source 1993 - Mechanisms of Ageing and Development Animal study Nerve growth factor receptor immunoreactivity in the cerebellar cortex of aged rats: effect of choline alfoscerate treatment ] , while supplementation with Alpha GPC in one study indicated an increase in brain function that has been directly related to the healthy supply of acetylcholine[7 Trusted Source 1992 - Pharmacology Biochemistry and Behavior Animal study Molecular mechanisms mediating the effects of l-α-glycerylphosphorylcholine, a new cognition-enhancing drug, on behavioral and biochemical parameters in young and aged rats ] .
Here’s a quick review of how that happens:
What is the best form of choline to take?
If you are looking to increase your acetylcholine levels, Alpha GPC is the answer. Alpha GPC can contribute to higher choline availability for its production. It has been shown to facilitate a quick increase in choline levels 1-2 hours after intake[8 Trusted Source 1992 - International Journal of Clinical Pharmacology, Therapy, and Toxicology Human study A comparative study of free plasma choline levels following intramuscular administration of L-alpha-glycerylphosphorylcholine and citicoline in normal volunteers ] . Since choline has many important functions in the body, its use to produce acetylcholine depends on the concentration of choline in the blood. Alpha-GPC increases choline levels faster than other types of choline. It was also found that upon absorption, Alpha GPC was incorporated into brain cells within 24 hours[9 Trusted Source 2007 - Journal of the Neurological Sciences Research evaluation Cholinergic precursors in the treatment of cognitive impairment of vascular origin: ineffective approaches or need for re-evaluation? ] .
Which is better, citicoline or Alpha GPC choline?
To sum up, the evidence says Alpha GPC. So, how do Citicoline vs Alpha GPC compare? Another choline that can freely enter the brain is CDP. It's also known as Citicoline. It is only 18% choline by weight, which means you will need double the dose to provide the same level of benefits as Alpha GPC. A study comparing CDP choline vs Alpha GPC found that Alpha GPC leads to higher efficiency on cognitive tests[10 Trusted Source 1991 - Journal of International Medical Research Human study A multicentre trial to evaluate the efficacy and tolerability of alpha-glycerylphosphorylcholine versus cytosine diphosphocholine in patients with vascular dementia ] and leads to higher efficiency on cognitive tests[11 Trusted Source 2023 - The Nutrition Source 3rd-party source Choline ] .
Choline bitartrate is another synthetic choline supplement. It provides the same amount of choline by weight as Alpha GPC. Since it cannot enter the brain due to its structure, it can be used for body benefits other than acetylcholine production.

Inexpensive Liver function It is when taking a recommended dose. As an essential nutrient, choline is not shown to have side effects under 3500 mg/day[11 Trusted Source 2020 - The Nutrition Source 3rd-party source Choline ] . Alpha GPC is well tolerated within the recommended levels. At higher than recommended doses, a small number of people may experience side effects such as headaches or dizziness. While Alpha GPC is the answer to the question which choline is best for brain, loads of supplements contain it. So, how to choose the best one? It is important to read the fine print carefully when choosing supplements. The following are three important points to remember to make an informed decision: Apart from a diet high in choline, supplementation can help meet recommended levels to ensure adequate choline is available to meet the body’s needs. Alpha GPC benefits stem from its rapid absorption, ease of entry into the brain and high choline content. It can provide benefits for your body and increase acetylcholine levels in the brain.
