As a source of choline, it can increase available levels of acetylcholine in the brain which supports better memory function and reasoning as well as improved synaptic plasticity. However, this formulation is considered to have low bio-availability and lacks the added nootropic benefits of supplements such as Citicoline and Alpha GPC.
This compound is produced by combining Choline with a derivative of Citric Acid.
It is one of the most widely used formulations of this vitamin found in Choline supplements marketed in your neighborhood health store, but many people wonder whether the Citrate form is the best version of Choline to purchase.
From a brain supplement standpoint, Alpha GPC Choline or CDP Choline (Citicoline) are proven to be more effective at improving intellectual power. However, Choline Citrate is very affordable and many athletes like using this formulation since it has energizing and cellular health promotion effects.
Patients who are suffering from things like chronic fatigue and even fibromyalgia could also benefit from Choline Citrate.
Choline Citrate is choline combined with citrate, an ester of citric acid. Citrate and choline helps in the synthesis of acetylcholine (ACh). The combination of these two ingredients increases the effectiveness of this source of choline above simply providing another source of choline to the brain.
Choline was declared an essential nutrient by the Food and Nutrition Board of the National Institute of Medicine (USA) in 1998.
Choline is considered an essential nutrient because when your body uses it faster than it can produce it, you need supplemental choline either from food or a supplement.
Choline is found in foods such as fish, beef steak, liver, chicken liver, eggs, cod, broccoli, peanut butter and milk.
You need choline for the production of the neurotransmitter acetylcholine. And to form Phosphatidylcholine (PC), a key ingredient in the membranes encasing each brain cell.
In fact, choline is so vital tocognition and nerve function that, without it, we couldn’t move, think, sleep or remember anything. Numerous human and animal studies have shown enhanced brain function when given supplemental choline.
Citrate is a citric acid ester which provides a third of the acetyl groups used in the acetylcholine (ACh) synthesis process. You can get citric acid from citrus fruit like lemons and limes.
And citrate plays another important role in the brain. Citrate is an intermediate in the Krebs cycle (also known as the TCA cycle or Tricarboxylic Acid cycle, or Citric acid cycle).
Citrate synthase catalyzes the condensation of oxaloacetate with acetyl CoA to form citrate. Citrate then acts as the substrate for aconitaseand is converted in aconitic acid. This cycle ends with the regeneration of oxaloacetate.
This series of chemical reactions is the source of 2/3’s of the energy we get from food. Most of the energy made available by these steps is transferred to form NADH. Which then drives adenosine triphosphate (ATP) synthesis that fuels mitochondria and provides the energy needed for brain cells.
Choline Citrate vs. Choline Bitartrate vs. CDP-Choline vs. Alpha GPC: What’s the Difference?
Choline is a water-soluble nutrient and its composition is similar to B-vitamins. Choline Citrate, Citicoline (CDP-Choline), Choline Bitartrate and Alpha GPC are all sources of choline.
Choline Citrate: An economical form of choline combined with citrate, and about 50% choline by weight. So 1 gram of Choline Citrate offers 500 mg of actual choline. Choline Citrate not only provides your brain with choline, but comes with one of the acetyl groups necessary for acetylcholine (ACh) synthesis.
Choline Bitartrate: An economical form of choline, and about 40% choline by weight. So 1 gram of Choline Bitartrate offers 400 mg of actual choline. It does not cross the blood-brain barrier as readily as other sources of choline. So you won’t experience the same level of nootropic benefits as with Alpha GPC or CDP-Choline.
Citicoline (CDP-Choline) (cytidine 5′-diphosphocholine): Is only about 18% choline by weight. Your body naturally synthesizes choline into CDP-Choline (Citicoline). It’s then converted to Phosphatidylcholine(PC) which is one of two fatty acids that make up the outer layer of cell membranes. And PC provides the choline needed to synthesize acetylcholine (ACh).
Alpha GPC: About 40% choline by weight and easily crosses the blood-brain barrier. Alpha GPC naturally occurs in your brain as a byproduct of phosphatidylcholine (PC). When your brain needs more choline, and the choline floating around in your brain is running low, it breaks down PC from cell membranes. And turns it into Alpha GPC.
Your body and brain loves it when you use choline. Because it doesn’t have to cannibalize its own cells to get more choline.
How does Choline Citrate work in the Brain?
Choline Citrate boosts brain health and function in several ways. But two in particular stand out.
Choline Citrate boosts acetylcholine (ACh)
1. Acetylcholine is a neurotransmitter tied to memory and overall brain function.Choline Citrate is a precursor to acetylcholine. Improving the efficiency of communications between neurons in your brain. This increase in neural signaling boosts memory, learning, cognitive processing and mental clarity.
But researchers found that circulating choline in the brain decreases with age. This study recruited younger adults between 20 and 40 years, and older adults between 60 and 85 years.
After fasting overnight, the subjects received 50 mg of a choline supplement per kilogram of body weight. Labs were drawn to determine choline concentration in the blood. And proton magnetic resonance spectroscopy (1H-MRS) was performed to determine the relative concentration of cytosolic choline-containing compounds in the brain.
Both tests were done before, and 3 hours after choline supplementation. Levels of choline in the blood and brain of study subjects were similar before choline supplementation.
But after choline supplementation, the younger subjects showed a 60% increase of choline in their blood and brain. The older subjects showed only a 16% increase in choline levels.
The researchers concluded circulating choline in the brain decreases with age. And given the key role of choline in brain function, this change may be a contributing factor in onset of late life neurodegeneration and dementia.
So according to this study, older adults should be supplementing with higher doses of a choline supplement like Choline Citrate to maintain cognitive function compared to younger adults.
Choline Citrate Boosts Memory
2. Researchers and medical professionals have long known about poor memory in people with a choline deficiency.
A study at Northwestern University in Chicago tested people with a choline deficiency. They gave them a series of memory tests and found their scores below average.
In this study, they then gave one group extra choline, and the others were given a placebo. After 24 weeks, both groups repeated memory tests.
The group who received extra choline showed a dramatic improvement in memory. The placebo group performed poorly as expected with scores the same as on the original test.
How things go bad
As we get older, our brain chemistry and energy metabolism changes. But choline deficiency can happen at any age from infancy through to our late adult years.
↓ Brain fog and/or a sense of confusion
↓ Fatigue or lack of energy
↓ Unable to learn new things
↓ Memory loss and poor recall
↓ Feeling distracted or irritable
↓ Poor balance
↓ Lack of energy/fatigue
Our bodies are influenced by the food we eat (and what we don’t eat!), what we drink, lifestyle habits, and even the air we breathe.
Choline Citrate can help reverse cognitive decline. It can help you perform better in your work, and at school. By boosting acetylcholine and repairing neural cell membranes.
Choline Citrate to the rescue
Research from hundreds of studies have shown that Choline will:
* Eliminate brain fog and confusion
* Boost energy
* Improve learning
* Enhance memory and recall
* Help focus and reduce irritability
* Improve physical performance
* Eliminate fatigue
Choline Citrate is water-soluble. After it’s digested it will enter your bloodstream and cross the blood-brain barrier. Once in your brain it boosts neural signal transmission, and helps repair neurons.
Choline Citrate improves your brain function and memory by increasing the production of acetylcholine. And prevents neurons from getting cannibalized when your brain is searching for more choline.How does Choline Citrate feel?
After taking Choline Citrate you should feel a boost in your ability to think, mood should improve, and your energy level should go up.
Choline Citrate influences the level of acetylcholine in your brain. This crucial neurotransmitter affects memory, cognition, recall and learning.
Low levels of choline will leave you with brain fog and an inability to think clearly. You may also experience a drop in mood and some irritability.
If you’re using anything from the Racetam-family of nootropics and you experience a headache – your brain is likely starved for choline.
Choline Boosts Cognition
The Framingham Heart Study is a long-term, ongoing cardiovascular study on residents in the town of Framingham, Massachusetts. The study began in 1948 with 5,209 adults. And is now on its 3rd generation of participants.
This study of Framingham Offspring involved 1,391 dementia-free subjects. Ages ranged from 36 – 83 years. The participants underwent a food-frequency questionnaire, and MRI brain scan. The study was in two parts, from 1991 to 1995, and 1998 to 2001.
Study participants were tested for verbal memory, visual memory, verbal learning and executive function. And a MRI-scan measured brain volume.
The study concluded that those residents with higher choline intake demonstrated significantly better cognitive performance.
Choline Citrate Helps with Exercise and Muscle Performance
Choline Citrate boosts mental energy, focus and concentration. All critical for physical activity and athletic performance.
Choline’s effect on your metabolism and neurotransmitters in the brain produce quicker reaction times. And shorten the time needed for mental processing.
Choline helps improve your energy levels, mood, and recovery time following a workout. It is also critical for muscle nerve function, and in preventing fatigue, muscle aches and pain following a workout.
When your muscles move, choline is needed to activate the neurotransmitter acetylcholine (ACh), which sends signals to muscles, and makes them move.
Researchers found that providing 2 grams of Choline prior to exercise prevented a fall in choline levels. And raised Choline levels above baseline values for up to 2 hours after exercise.
The researchers found that Choline Citrate and Choline Bitartrate were equally effective. One randomized, placebo-controlled study found improvements in running times by a significant amount over a 20-mile course when compared to those using a placebo.
Choline Citrate is sold in capsule or powder form. Capsules are usually 500 – 650 mg each.
