What is Choline?

Choline is an essential nutrient that plays a role in synthesizing many neurotransmitters and hormones. It’s also necessary for maintaining healthy levels of blood lipids, including cholesterol. Signs of a choline deficiency are muscle weakness, fatigue, confusion, depression, and memory loss.

Choline is a macronutrient that is necessary for liver function, appropriate brain development, neuron function, muscular movement, energy support, and metabolic health. Choline is found in several kinds of foods that naturally include certain fats in the form of phosphatidylcholine, a chemical that makes up the structural component of fat. Choline is involved in several key activities that occur hundreds of times every day in the human body.

Choline is a water-soluble substance linked to other vitamins, including folate and the B vitamin complex. Choline, like B vitamins, is important for maintaining energy and cognitive function and keeping the metabolism functioning.

What is the most beneficial use of choline? Choline aids in the methylation process, which is necessary for DNA synthesis, nerve signaling, and detoxification. It’s also necessary for the function of acetylcholine, a crucial neurotransmitter that helps neurons connect and muscles move, as well as acting as an anti-aging neurotransmitter and performing other fundamental functions.

Choline is not classified as a mineral or a vitamin, yet it is a vital micronutrient for various bodily activities, including brain function. Therefore, while the USDA does not have an official Daily Value Recommendation for Choline at this time, it is critical to prevent a choline shortage from maintaining numerous physiological systems, including the neurological, endocrine, digestive, and reproductive systems.

Choline Consumption Recommendations

Our bodies can produce a tiny amount of choline on their own, but we must get the rest from the diet.

Where can you find choline? Eggs, liver, steak, salmon, cauliflower, Brussel sprouts, and breast milk are all-natural sources of choline. In fact, due to their high choline content, eggs are commonly referred to as “brain food.”

Choline was just included in the needed nutrients list of the National Academy of Sciences (NAS) in 1998, making it one of the most recent additions of all nutrients. Choline is currently being investigated to learn more about its possible advantages and applications. Still, most experts think that the doses stated below are adequate for creating optimum benefits while causing no damage at this time:

  • 125–150 mg for infants and babies
  • 150–250 mg for children aged 1 to 8
  • 250–375 mg for adolescent boys and girls aged 8 to 13
  • 425–550 mg for women over 14 years old
  • 550 mg for men over the age of 14
  • 450–550 mg for pregnant women
  • 550 mg for nursing mothers

Supplements containing choline

Some experts propose consuming even more choline to improve brain function and memory retention. However, according to some studies, a portion of the choline contained in dietary sources is not absorbed by the body, which might be one reason why certain individuals, particularly those with liver disease, can develop a choline deficit. Instead, choline is partly digested in the liver.

If you decide to take choline supplements, look for ones that are manufactured from whole foods and are of extremely high quality. There are a variety of choline supplements available, some of which are more easily absorbed and used by the body, while others may not offer the same broad range of benefits.

This has to do with how your body transforms choline to the chemical acetylcholine, which is responsible for many of the health advantages of choline. Once consumed, different forms of choline have different abilities to pass the blood-brain barrier.

According to some scientists, CDP choline, also known as Citicoline, or Alpha GPC choline, is in the form of choline that the body uses best. In addition, according to some sources, these are the most effective kinds of choline that offer the greatest advantages in the body since they closely resemble the way choline is present naturally in dietary sources.

Symptoms and Signs of Choline Deficiency

Some data suggests that most individuals do not get enough choline in their diets, even consuming choline-rich foods, since some choline is not absorbed. As a result, even though most individuals regularly consume meals rich in choline, some variables make choline difficult to absorb. As a result, studies reveal that the typical person does not have enough choline in their body to satisfy the daily guideline.

This is most likely due to hereditary factors that cause a greater demand for choline in certain persons. In addition, according to experts, 50 percent of the population may have genes that enhance dietary methyl needs, which might lead to a choline shortfall since choline is a key source of methyl processes.

Researchers are currently arguing how much choline the general population should ingest each day. Still, the subject is difficult to agree on since there seems to be a wide variety of choline demands, with some individuals requiring far more than others. As a result, determining an average quantity is difficult.

The following are some of the signs and symptoms of a choline deficiency:

  • fatigued with low energy levels
  • loss of memory
  • mental deterioration
  • difficulties with learning
  • muscular pains
  • injury to the nerves
  • mood swings or disturbances

People who have “fatty liver,” a liver ailment, are more likely to have a choline shortage and have unfavorable effects. Fatty liver, commonly known as fatty liver disease (FLD), is a reversible disorder in which triglyceride fat builds up in the liver cells. People who drink too much alcohol, are obese, have diabetes or insulin resistance, or have other conditions that affect fat metabolism are more likely to get it.

A lack of choline may also contribute to age-related cognitive decline, such as memory loss and Alzheimer’s disease. This is because choline aids in the maintenance of neurotransmitters, and as people age, nerve signaling may deteriorate, resulting in dementia symptoms.

The easiest approach to guarantee enough choline is eating a diversified diet. Because choline is abundant in animal products, vegetarians and vegans are more likely to suffer from a choline deficit.

It’s also worth noting that folate aids in the body’s capacity to produce and use choline since the two nutrients have a close working connection and depend on one another. Researchers assumed that humans could manufacture enough choline on their own, but recent research has shown that this is not the case, resulting in choline being added to the list of essential nutrients.

According to a new study, the quantity of folate you eat may influence how much choline your body generates and requires from food sources. For example, someone who consumes more folate from leafy green vegetables and certain grains would need less choline from food.

12 Choline-Rich Foods

Natural sources of choline and many other nutrients may be found in the following 12 foods. The figures below are based on a daily intake of 550 milligrams.

1. Liver of Beef – 283 milligrams per 3 ounces (51 percent DV)

2. Salmon – 242 milligrams per filet (44 percent DV)

3. Chickpeas – 198 milligrams in 1 cup uncooked (36 percent DV)

4. Peas Split – 188 milligrams in 1 cup uncooked (34 percent DV)

5. Navy Beans – 181 milligrams in 1 cup raw (32 percent DV)

6. Eggs – 147 milligrams per big egg (27 percent DV)

7. Beef from Grass-Fed Cows – 78 milligrams per 3 ounces (14 percent DV)

8. Turkey – 57 milligrams per 3 ounces (10 percent DV)

9. Chicken Breast – 50 milligrams per 3 ounces (9 percent DV)

10. Cauliflower- 47 milligrams per cup raw (8 percent DV)

11. Goat Milk – 39 milligrams per cup (7 percent DV)

12. Brussel Sprouts (12 oz.) – 17 milligrams per cup raw (3 percent DV)

Soy Lecithin & Choline

It’s also worth mentioning that soy products, particularly soy lecithin, contain choline. Choline is an important component of lecithin (phosphatidylcholine), a fat-like substance that is present in our cells. Soy lecithin is a contentious ingredient that is used as an emulsifier in the food and offered as a supplement.

Choline, as well as fatty acids, glycerol, and phospholipids, are found in soy lecithin. Originally generated from egg yolks, it is now made from cottonseeds, marine sources, milk, sunflowers, or, most often, soybeans. Lecithin serves various functions in the body, including assisting in the maintenance of cell membranes, the transmission of nerve impulses, the processing of fat and cholesterol, and other functions.

Many processed, packaged goods include soy lecithin, which helps bond foods and works as an emulsifier, maintaining the texture of foods and extending their shelf life. Although the FDA considers soy lecithin to be safe, it might cause adverse effects such as nausea, bloating, constipation, skin rashes, stomach discomfort, and other digestive issues.

I also have concerns about soy lecithin in general, such as its isoflavones, which have estrogenic effects on the body. The bulk of soy now on the market is genetically engineered. Because there’s no way to tell where soy lecithin comes from, we should presume it’s derived from GM soy unless it’s certified as organic.

On the other hand, Soy lecithin may provide health advantages, such as lowering cholesterol, improving cognitive function, alleviating menopausal symptoms, and helping the body cope with stress.

When it comes to receiving choline from soy products, I recommend consuming organic fermented soy products in moderation (tempeh, natto, miso) and avoiding unfermented soy, particularly non-organic and processed varieties. As you can see, there are lots of different choline sources that provide many more health advantages without the hazards, such as wild salmon, cage-free eggs, and even some veggies, so why not get the majority of your choline from these foods?

Choline’s Health Advantages

1. Contributes to the formation of DNA and cell structures

Choline aids fat absorption, and fats are subsequently used to form cell membranes and structures. Our cells can’t effectively keep their structure or send signals to other body sections if we don’t have enough choline in our bodies.

What part of the body does choline play in gene expression and DNA? Choline is required for the production of DNA, which is responsible for the formation of the complete bodily structure. In addition, choline and folate are recognized to be important nutrients in the methyl group processes, which the body employs to create genetic information that aids in the development of all of the body’s systems.

2. It aids in the proper functioning of the central nervous system

One of the most important properties of choline is that the body utilizes it in several critical ways for nerve function, such as assisting nerve signaling and maintaining brain cell membranes.

Choline also aids in forming tissue in the nervous system that aids in brain development and growth. In addition, choline boosts nerve signaling capacity, sustains structural integrity, and preserves crucial neuronal membranes.

Choline is a precursor to several key neurotransmitters, including acetylcholine, which is necessary for normal nerve and muscle function. Neurotransmitters are chemical messengers that continually carry information from one system to the next throughout the body.

Because the neurotransmitter acetylcholine is involved in memory and learning, a choline deficit may lead to poor focus, memory loss, mood swings, and other cognitive issues, particularly as people age. In addition, because an acetate molecule joins with a choline molecule to generate acetylcholine, this molecule cannot be adequately synthesized without enough choline in the body, and brain function may suffer as a result.

3. Helps to keep the liver in good shape

Choline is required to transfer fat from the liver to all of the body’s cells. Because choline is largely responsible for keeping the liver free of fat build-up that may develop and cause injury, one of the benefits of choline is liver cleansing. Choline is involved in the movement of cholesterol and triglycerides, two essential lipids, from the liver to other body regions.

According to several research, persons with low amounts of choline in their bodies are more likely to suffer liver damage and possibly liver failure. Choline also aids in the formation of LDL cholesterol in the liver, and although LDL is considered the “bad” sort of cholesterol, it is still required for good functioning – if there isn’t enough, the body will store fat in the liver.

4. Assists in the prevention of memory loss and cognitive decline

Another advantage of choline is that it helps to keep your memory sharp as you become older. Choline is a component of cell membranes and neurotransmitters utilized in nerve communication. It helps maintain memory and prevent dementia, memory loss, and other indicators of cognitive decline as people age.

Our brain gets less elastic as we become older. Choline helps preserve brain flexibility by assisting in maintaining acetylcholine levels, which typically fall with age.

According to certain research, low levels of acetylcholine have been linked to cognitive loss, including Alzheimer’s disease and senile dementia. Patients with Alzheimer’s disease have low acetylcholine levels at times, and certain Alzheimer’s treatments imitate choline’s action of enhancing this neurotransmitter’s effects.

5. Can Aid Muscle Function and Exercise Performance

Choline boosts mental energy, attention, and focus, all of which are crucial for physical activity and sports performance. In addition, choline’s influence on metabolism and neurotransmitters in the brain is thought to speed up response times and reduce the amount of time required for mental processing.

Choline may also aid in the improvement of energy levels, mood, sleep cycles, and recuperation time after severe exercise. Choline is also involved in muscular nerve activity and may help avoid tiredness and muscle aches and pains after exercise. Choline is required to activate the neurotransmitter acetylcholine, which transmits chemical messages to muscles and allows them to move throughout the body.

6. It may help you keep your heart healthy

Choline and folate aid in converting homocysteine, preventing the body from collecting too much fat and perhaps lowering the risk of a heart attack or stroke. High homocysteine levels have been linked to the development of heart and blood vessel problems. Homocysteine is an amino acid that enters the body through protein sources, usually meat.

Some studies have shown that choline and lecithin may help decrease blood cholesterol and lessen the risk of heart disease. Still, the findings have been mixed, so more study is required before physicians start prescribing choline for its capacity to lower LDL (“bad”) cholesterol and triglycerides.

7. Helps to Maintain a Healthy Pregnancy

Choline is an important part of a pregnant woman’s diet. Why? Fetuses quickly utilize choline while their brains, cell structures, and nerve channels are growing; therefore, pregnant women need significantly more than anybody else. Some studies even demonstrate that if a baby gets enough choline throughout pregnancy, they have a greater chance of having a healthy, bright brain later in life and a decreased risk of brain abnormalities. Conversely, other research have shown that pregnant women with low blood choline levels are more likely to have infants with neural tube abnormalities and developmental issues.

Choline is also present naturally in breast milk since it is necessary for a newborn’s growth and development. It’s for this reason that it’s included in most newborn formulae. In addition, because neuron synapses grow at a high pace in the brains of fetuses and newborns, choline plays an important role in helping to create the basis for the brain’s structure.

Because of its link with folate, choline is also vital during pregnancy. Choline, folate, and B vitamins all work together to maintain each other’s levels balanced. In addition, choline is one of the body’s methyl donors, which means that when folate, a critical vitamin for embryonic development, is deficient, choline may assist in filling in the gaps and carrying out bodily tasks where folate is required but not present.

8. Vital to the growth and development of children

The capacity of the brain to form new neuron connections is known as neuron plasticity, and choline is regarded to be essential for brain flexibility and plasticity.

Choline is essential to assist youngsters in improving brain function as they become older since it involves learning, memory, logical thinking, and focus. In addition, children need choline to create neurotransmitter channels in their brains, which aid in memory, language ability, creative thinking, arithmetic skills, and social signals, among other things.

Choline is required to form new brain connections called synapses, which is the chemical process required for memories to develop in the brain. According to several studies, choline may aid in the prevention of learning disorders, such as ADHD and increase focus in children and teenagers.


Choline is generally regarded as a healthy vitamin with few unwanted side effects. However, it may become poisonous when eaten in excess, just like any other vitamin.

If you consume much more choline than is suggested, you may develop symptoms such as diarrhea, nausea, exhaustion, elevated blood pressure, excessive sweating, and a fishy odor on your skin. Therefore, always read the suggested quantity of any supplement you take before taking it, and follow it unless you talk with your doctor first.
