Citicoline is a nutrient commonly sold as a brain supplement to improve overall mental performance.

But it does much more than that.

Citicoline can boost the levels of important neurotransmitters, increase energy available to the brain, and protect it from foreign substances.

What Is Citicoline?

Citicoline is a naturally occurring compound found in every cell of the body, but it’s particularly important for your brain.

It’s found in very few foods, particularly ones not often found in the Western diet, mainly liver and brain.

Some citicoline can be synthesized from the choline found in choline-rich foods like eggs, beef, and seafood. (1)

But if you want the therapeutic brain benefits of citicoline, you can’t count on getting more from food beyond what your body normally manufactures.

You’ll need to take a supplement.

Interestingly, when you take a citicoline supplement, it gets broken down into choline and cytidine which are readily absorbed in the intestines. (2)

These substances easily cross the blood-brain barrier where they are re-formed into citicoline. (3)

CDP-Choline, Cognizin, and Other Names for Citicoline

Citicoline (cytidine 5’-diphosphocholine) is sold as a supplement in over 70 countries and goes by dozens of common names — it can get confusing! (4)

The most common synonym for citicoline is CDP-choline.

You’ll also see many supplements that contain Cognizin.

This is the brand name of a patented, highly bioavailable form of citicoline used in some of the better brands of brain supplements.

Cognizin, unlike other sources of citicoline, has been clinically tested in humans.

So far, it has been found to increase motor speed, improve attention, increase energy to the brain, encourage the formation of brain cell membranes, and reduce the impulsiveness of ADHD. (5, 67)

If you are not in the US, you can find a list of international citicoline names on

Now let’s get on to the exciting stuff — the benefits of citicoline for your brain and mental health.

Citicoline Raises Levels of Important Brain Chemicals

Your brain cells communicate with each other via brain chemicals called neurotransmitters.

Citicoline raises the levels of several important neurotransmitters, including acetylcholine and dopamine. (8)

Acetylcholine is the brain chemical associated with memory and learning.

You need acetylcholine to turn short-term memories into long-term ones.

Unfortunately, many prescription drugs are anticholinergic which means that they block the action of acetylcholine.

A good rule of thumb is that any medications that start with “anti,” such as antihistamines or antidepressants, are likely to affect your acetylcholine levels.

This includes seemingly innocuous over-the-counter remedies like Benadryl.

If you take any anticholinergic medications, supplementing with citicoline will help bring up your levels of acetylcholine.

Dopamine is your “motivation molecule.”

It increases your motivation, productivity, and focus.

A low dopamine level can leave you feeling depressed and “blah” with little enthusiasm for life.

People low in this brain chemical often self-medicate with caffeine, sugar, and other stimulants (including substance abuse) and engage in other risky behaviors to get their dopamine boost.

Citicoline is a safe way to increase dopamine naturally.

It works in two ways — by raising the level of dopamine and by increasing the number of dopamine receptors in the brain. (9)

Citicoline Increases Energy Available to the Brain

Your brain uses a lot of energy — 20% of your daily calorie and oxygen intake. (10)

But your brain can’t store energy, so it needs a constant supply.

It gets energy, usually in the form of glucose, from blood flowing to the brain.

Citicoline enhances glucose metabolism and increases blood flow to the brain. (11)

Poor circulation to the brain can cause neurological problems, including memory loss, fatigue, vertigo, and stroke. (12)

Citicoline is so effective at increasing circulation to the brain that doctors throughout Europe have been prescribing it for this reason for years.

Another way citicoline increases brain energy is by firing up brain cell mitochondria.

Every cell in your body and brain gets energy from these little cellular powerhouses.

Citicoline increases mitochondrial energy production in the frontal cortex, the part of the brain responsible for language, thinking, decision making, and planning. (13)

Citicoline Is a Nootropic

Citicoline is considered a nootropic and is often sold as either a single ingredient supplement or included in nootropic brain supplement formulas.

The term nootropic originally meant a drug that enhances learning and memory, is neuroprotective, and is very safe with few side effects. (14)

But the definition has grown broader to now include any substance, pharmaceutical or natural, that improves mental functions such as memory, intelligence, motivation, attention, and concentration.

One study that compared citicoline to several popular nootropics found that it improved memory and cognition as well as the study drug piracetam. (15)

Studies have found that citicoline can significantly improve memory, motor speed, focus, and attention. (1617)

Citicoline Protects Your Brain From Harmful Foreign Substances

Every brain cell has a semi-permeable membrane that acts as a gatekeeper.

This membrane lets in the nutrients, water, and oxygen your brain cells need to survive, while filtering out harmful foreign substances.

It does this so elegantly and intelligently that it’s been called the “brain of the cell.”

But brain cell membranes can get leaky, letting metabolic waste, heavy metals, toxins, pathogens, and other unwanted invaders into your brain.

Citicoline plays an important role in cell membrane integrity.

It’s the precursor of phosphatidylcholine, a phospholipid that is a major component of brain cell membranes. (18)

It is also a natural cell membrane stabilizer, which is one of the reasons it’s so useful for treating strokes. (19)

Citicoline Slows Down Brain Cell Aging

Two major underlying causes of cellular aging are free radical damage and inflammation.

Citicoline can offset the harmful effects of both. (20, 21)

Your brain is under constant attack from free radicals, unattached oxygen molecules that attack cells in much the same way that oxygen causes metal to rust.

Since your brain uses so much oxygen, it’s particularly susceptible to free radical damage (also called oxidative stress).

Free radicals trigger inflammation, a major cause of cellular aging.

Brain inflammation contributes to a wide variety of brain-related disorders, including: (2223)

  • ADHD
  • Alzheimer’s disease
  • anxiety
  • brain fog
  • depression
  • memory loss
  • stroke

Citicoline Is Used to Treat Serious Neurological Disorders

Since citicoline is sold as a supplement, it may seem like a lightweight remedy, but in fact it was initially used as a prescription medication.

Citicoline was originally synthesized in Japan where it was first used to help stroke victims.

Later, doctors throughout Europe prescribed citicoline for cognitive problems, although it’s now available as a supplement there as well.

Citicoline shows promise in treating a wide variety of neurological conditions, including: (24)

  • age-related memory loss
  • Alzheimer’s disease
  • dementia
  • Parkinson’s disease
  • stroke

It can reduce the severity of symptoms resulting from traumatic head injuries.

Health care professionals sometimes administer it orally, intravenously, or by injection for enhanced stroke recovery and for chronic cerebrovascular disease. (25)

Here are some of the mechanisms by which citicoline can help even serious neurological disorders: (26)

  • increases blood flow to the brain
  • protects the brain from further damage
  • builds healthy cell membranes
  • increases neuroplasticity, your brain’s ability to continually renew itself
  • increases neurogenesis, the capacity to grow new brain cells
  • increases acetylcholine levels

Alzheimer’s patients typically have very low acetylcholine levels, often only 10% of what’s considered normal. (27)

Drugs that treat Alzheimer’s, like Aricept, work by blocking the breakdown of acetylcholine.

Citicoline Aids Mental Health Disorders

Citicoline positively impacts brain function in some interesting and diverse ways.

It can be helpful for addictions.

By increasing dopamine, citicoline reduces drug cravings in cocaine addicts. (28)

It helps repair brain cell membranes damaged by cocaine use.

Citicoline changes the brain’s response to food stimuli which can result in a significant decrease in appetite. (29)

In patients with schizophrenia, citicoline has improved numerous cognitive functions — processing speed, working memory, verbal learning, and verbal memory. (30)

Citicoline also exhibits antidepressant properties, especially in early-onset Alzheimer’s patients. (31)

Citicoline Supplement Dosage, Side Effects, and Interactions

There is no Recommended Dietary Allowance (RDA) for citicoline, but a typical dose is 250-1,000 mg taken twice a day. (32)

A daily total of 1,000-2,000 mg is recommended to support cognitive skills. (33)

The best citicoline supplements often contain Cognizin, a patented form of citicoline which has been studied in clinical trials.

Brands that contain Cognizin include Mind Lab Pro, BestVite, Jarrow, Life Extension, Swanson, and Vitacost.

Citicoline supplements are well absorbed and highly bioavailable. (34)

Citicoline is considered safe for both adults and children.

Reported side effects are unusual, but include insomnia, headache, digestive upset, change in blood pressure, blurred vision, and chest pains. (35)

Oddly, high doses over 10,000 mg can cause a fishy body odor. (36)

Talk to your doctor before taking citicoline with levodopa, a medication used to treat Parkinson’s disease. (37)

Citicoline can enhance this drug’s effectiveness and so may require a change in medication dosage.

Citicoline in Energy Drinks and “Think” Drinks

Energy drinks which are designed to increase both physical energy and mental alertness have become a multibillion dollar industry. (38)

A relatively new subset of energy drinks are brain or “think” drinks which claim to enhance cognitive performance by improving memory, focus, and concentration.

A surprising number of these drinks contain citicoline.

5-Hour ENERGY Shot, Alsa Energy Drink, and Y.E.S. Energy Shot are examples of energy drinks that contain citicoline.

INVIA, formerly sold under the brand name Nawgan, is a powdered brain drink mix that contains Cognizin along with vitamins B6, B12, and E, artificial sweeteners, and a healthy dose of caffeine (100 mg).

But energy and brain drinks are not the most reliable or cost-effective ways to get a daily dose of citicoline.

According to the International Society of Sports Nutrition, any performance enhancement from energy drinks comes from sugar and caffeine, NOT from other added ingredients. (39)

Plus there’s a growing health concern about the safety of these drinks.

Commonly reported side effects of energy drinks include insomnia, headache, heart palpitations, irritability, chest pain, and digestive upset — mainly due to too much caffeine. (40)

For these reasons, we recommend you get your citicoline from supplements, not designer drinks.

Citicoline Benefits: Take the Next Step

Citicoline is a little-known nutrient that naturally occurs in the brain and body.

It can help your brain health and function in a variety of ways — by raising levels of important neurotransmitters, increasing mental energy, and protecting your brain from damage, toxins, and aging.

It’s been proven beneficial for a wide range of brain disorders and mental health conditions, as well as general cognitive enhancement.

Citicoline supplements are well-absorbed and generally safe, with few side effects.

Citicoline is one of the few substances available as a supplement that is also powerful enough to be used therapeutically for serious neurological disorders.

You can take citicoline on its own, but it’s often included in supplement formulas where it works synergistically with other ingredients.
