Choline is a basic constituent of lecithin that is found in many plants and animal organs. It is important as a precursor of acetylcholine, as a methyl donor in various metabolic processes, and in lipid metabolism. Choline is now considered to be an essential vitamin. While humans can synthesize small amounts (by converting phosphatidylethanolamine to phosphatidylcholine), it must be consumed in the diet to maintain health. Required levels are between 425 mg/day (female) and 550 mg/day (male). Milk, eggs, liver, and peanuts are especially rich in choline. Most choline is found in phospholipids, namely phosphatidylcholine or lecithin. Choline can be oxidized to form betaine, which is a methyl source for many reactions (i. e. conversion of homocysteine into methionine). Lack of sufficient amounts of choline in the diet can lead to a fatty liver condition and general liver damage. This arises from the lack of VLDL, which is necessary to transport fats away from the liver. Choline deficiency also leads to elevated serum levels of alanine aminotransferase and is associated with an increased incidence of liver cancer.

Vitamin B4 /Choline is a water-soluble vitamin-like essential nutrient. It is a constituent of lecithin, which is present in many plants and animal organs. The term cholines refers to the class of quaternary ammonium salts containing the N, N, N-trimethylethanolammonium cation(X− on the right denotes an undefined counteranion).

The cation appears in the head groups of phosphatidylcholine and sphingomyelin, two classes of phospholipid that are abundant in cell membranes. Choline is the precursor for the neurotransmitter acetylcholine, which is involved in many functions including memory and muscle control. Lipotropic means that choline possesses properties that prevent the excessive accumulation of fat in the liver. Although not officially deemed a Vitamin per the FDA definition, make no mistake about it, choline is an essential and vital nutrient for our health.

Deficiency Symptoms of Vitamin B4 / Choline

Food Sources of Vitamin B4 / Choline

Some animals cannot produce choline but must consume it through their diet to remain healthy. Humans make a small amount of choline in the liver. In the United States, choline is recommended as an essential nutrient. Possible benefits include reducing the risk of neural tube defects and fatty liver disease. It has also been found that intake of choline during pregnancy can have long-term beneficial effects on memory for the child. Several food sources of choline are listed in

DV = Daily Value. DVs were developed by the U.S. Food and Drug Administration (FDA) to help consumers compare the nutrient contents of products within the context of a total diet. The DV for choline is 550 mg for adults and children age 4 and older. However, the FDA does not require food labels to list choline content unless a food has been fortified with this nutrient. Foods providing 20% or more of the DV are considered to be high sources of a nutrient.

Choline deficiency is rare in the general population. The European Food Safety Authority states there are no Recommended Daily Intakes in the EU and “no indications of inadequate choline intakes available in the EU”.

Dietary Supplements for Choline

Choline is available in dietary supplements containing choline only, in combination with B-complex vitamins, and in some multivitamin/multimineral products [rx]. Typical amounts of choline in dietary supplements range from 10 mg to 250 mg. The forms of choline in dietary supplements include choline bitartrate, phosphatidylcholine, and lecithin. No studies have compared the relative bioavailability of choline from these different forms.

Recommended Intakes of Vitamin B4 / Choline

Intake recommendations for choline and other nutrients are provided in the Dietary Reference Intakes (DRIs) developed by the Food and Nutrition Board (FNB) of the Institute of Medicine (IOM). DRIs is the general term for a set of reference values used for planning and assessing nutrient intakes of healthy people. These values, which vary by age and sex, include:

  • Recommended Dietary Allowance (RDA) – Average daily level of intake sufficient to meet the nutrient requirements of nearly all (97%–98%) healthy individuals; often used to plan nutritionally adequate diets for individuals.
  • Adequate Intake (AI) – Intake at this level is assumed to ensure nutritional adequacy; established when evidence is insufficient to develop an RDA.
  • Estimated Average Requirement (EAR) –  Average daily level of intake estimated to meet the requirements of 50% of healthy individuals; usually used to assess the nutrient intakes of groups of people and to plan nutritionally adequate diets for them; can also be used to assess the nutrient intakes of individuals.
  • Tolerable Upper Intake Level (UL) – Maximum daily intake unlikely to cause adverse health effects.



Insufficient data were available to establish an EAR for choline, so the FNB established AIs for all ages that are based on the prevention of liver damage as measured by serum alanine aminotransferase levels. The amount of choline that individuals need is influenced by the amount of methionine, betaine, and folate in the diet; gender; pregnancy; lactation; stage of development; ability to produce choline endogenously; and genetic mutations that affect choline needs.

Adequate Intakes (AIs) for Choline 
Age Male Female Pregnancy Lactation
Birth to 6 months 125 mg/day 125 mg/day
7–12 months 150 mg/day 150 mg/day
1–3 years 200 mg/day 200 mg/day
4–8 years 250 mg/day 250 mg/day

Health Benefit of Vitamin B4 / Choline

  • Liver disease caused by exclusive feeding by vein (parenteral nutrition) – Giving choline intravenously (by IV) treats liver disease in people receiving parenteral nutrition who are choline-deficient.
  • Asthma – Taking choline seems to lessen symptoms and the number of days that asthma is a problem for some people. It also seems to reduce the need to use bronchodilators. There is some evidence that higher doses of choline (3 grams daily) might be more effective than lower doses (1.5 grams daily).
  • Neural tube defects – Some research indicates that women who consume a lot of choline in their diet around the time of conception have a lower risk of having babies with a neural tube defect, compared to women with lower intake.
  • Alzheimer’s disease – Taking choline by mouth, alone or together with lecithin, does not reduce symptoms of Alzheimer’s disease.
  • Athletic performance – Taking choline by mouth does not seem to improve athletic performance or lessen fatigue during exercise.
  • A brain condition called cerebellar ataxia – Early research suggests that taking choline by mouth daily might improve motor function in people with a brain condition called cerebellar ataxia. However, other research shows that taking choline does not improve cerebellar ataxia in most people.
  • Memory loss due to age – Taking choline by mouth does not improve memory in older people with memory loss.
  • Schizophrenia – Taking choline by mouth does not reduce symptoms of schizophrenia.
  • Liver disease caused by exclusive feeding by vein (parenteral nutrition).Giving choline intravenously (by IV) treats liver disease in people receiving parenteral nutrition who are choline-deficient.
  • Asthma – Taking choline seems to lessen symptoms and the number of days that asthma is a problem for some people. It also seems to reduce the need to use bronchodilators.

  • Memory loss due to age – Taking choline by mouth does not improve memory in older people with memory loss.
  • Schizophrenia. Taking choline by mouth does not reduce symptoms of schizophrenia.
  • Allergies (hayfever) – Early research suggests that taking a particular type of choline daily for 8 weeks is not as effective as a nasal spray for reducing allergy symptoms.
  • Bipolar disorder – Early research suggests that taking choline might reduce some mood symptoms in people with bipolar disorder who are taking lithium.
  • Bronchitis – Early research suggests that inhaling choline might improve symptoms of bronchitis caused by dust.
  • Mental performance – Early research suggests that taking a single dose of choline does not improve reaction time, reasoning, memory, or other mental functions. Other research suggests choline can improve visual memory, but not other aspects of mental function when given along with intravenous feeding (parenteral nutrition).
  • Seizures – There are reports that taking high doses of choline might be helpful for some people with a type of seizure called complex partial seizures.
  • Early research suggests that taking a particular type of choline daily for 8 weeks is not as effective as a nasal spray for reducing allergy symptoms.
  • Early research suggests that taking choline might reduce some mood symptoms in people with bipolar disorder who are taking lithium.

Choline and Healthful Diets

The federal government’s 2015–2020 Dietary Guidelines for Americans notes that “Nutritional needs should be met primarily from foods. Foods in nutrient-dense forms contain essential vitamins and minerals and also dietary fiber and other naturally occurring substances that may have positive health effects. In some cases, fortified foods and dietary supplements may be useful in providing one or more nutrients that otherwise may be consumed in less-than-recommended amounts.”

For more information about building a healthy diet, refer to the Dietary Guidelines for AmericansCholine; Deficiency Symptoms, Food Source, Health Benefit and the U.S. Department of Agriculture’s MyPlate.Choline; Deficiency Symptoms, Food Source, Health Benefit

The Dietary Guidelines for Americans describes a healthy eating pattern as one that:

  • Includes a variety of vegetables, fruits, whole grains, fat-free or low-fat milk and milk products, and oils.
  • Many vegetables, fruits, whole grains, and dairy products contain choline.
  • Includes a variety of protein foods, including seafood, lean meats and poultry, eggs, legumes (beans and peas), nuts, seeds, and soy products.
  • Fish, beef, poultry, eggs, and some beans and nuts are rich sources of choline.
  • Limits saturated and trans fats, added sugars, and sodium.
  • Stays within your daily calorie needs.

Doctor visit helper

Prepare before seeing a doctor

A simple rural-patient checklist to help you explain symptoms clearly, ask better questions, and avoid unsafe self-treatment.

Safety note: This is not a prescription or diagnosis. For severe symptoms, pregnancy danger signs, children with serious illness, chest pain, breathing difficulty, stroke-like weakness, or major injury, seek urgent care.

Which doctor may help?

Start with a registered doctor or the nearest qualified health center.

What to tell the doctor

  • Write when the problem started and how it changed.
  • Bring old prescriptions, investigation reports, and current medicines.
  • Write allergies, pregnancy status, diabetes, kidney/liver disease, and major past illnesses.
  • Bring one family member if the patient is weak, elderly, confused, or a child.

Questions to ask

  • What is the most likely cause of my symptoms?
  • Which danger signs mean I should go to hospital quickly?
  • Which tests are necessary now, and which can wait?
  • How should I take medicines safely and what side effects should I watch for?
  • When should I come for follow-up?

Tests to discuss

  • Vital signs: temperature, pulse, blood pressure, oxygen saturation
  • Basic physical examination by a clinician
  • CBC, urine test, blood sugar, or imaging only when clinically needed

Avoid these mistakes

  • Do not use antibiotics, steroid tablets/injections, or strong painkillers without proper medical advice.
  • Do not hide pregnancy, kidney disease, ulcer, allergy, or blood thinner use.
  • Do not delay emergency care when danger signs are present.

Medicine safety and first-aid guide

This section is for patient education only. It does not replace a doctor, pharmacist, or emergency care.

Safe first steps

  • Drink safe fluids and monitor temperature.
  • In dengue-prone areas, discuss CBC and platelet count when fever persists or warning signs appear.
  • Use tepid sponging for high fever discomfort; avoid ice-cold bathing.

OTC medicine safety

  • For fever, common fever medicine may be discussed with a clinician or pharmacist.
  • Avoid aspirin/ibuprofen-like medicines in suspected dengue unless a doctor says it is safe.

Avoid these mistakes

  • Do not start antibiotics without a proper medical decision.
  • Do not use steroid tablets or injections casually for quick relief.
  • Do not delay emergency care because of home remedies.

Get urgent help if

  • Fever with breathing difficulty, confusion, repeated vomiting, bleeding, severe weakness, stiff neck, or dehydration needs urgent care.
Medicine names, dose, and timing must be decided by a qualified clinician or pharmacist after checking age, pregnancy, allergy, other diseases, and current medicines.

For rural patients and family caregivers

Patient health record and symptom diary

Doctor to discuss: Medicine doctor / pediatrician for children / qualified clinician
Tests to discuss with doctor
  • Temperature chart and hydration assessment
  • CBC with platelet count if fever persists or dengue/other infection is possible
  • Urine test, malaria/dengue tests, chest evaluation, or blood culture only when clinically indicated
Questions to ask
  • What is the most likely cause of my symptoms?
  • Which warning signs mean I should go to emergency care?
  • Which tests are really needed now?
  • Which medicines are safe for my age, pregnancy status, allergy, kidney/liver/stomach condition, and current medicines?
  • Do I need antibiotics, or is this more likely viral?

Emergency warning signs such as chest pain, severe breathing difficulty, sudden weakness, confusion, severe dehydration, major injury, or loss of bladder/bowel control need urgent medical care. Do not wait for online information.

Safe pathway to proper treatment

Care roadmap for: Choline; Deficiency Symptoms, Food Source, Health Benefit

Use this simple roadmap to understand the next safe steps. It is educational and does not replace examination by a doctor.

Go to emergency care if you notice:
  • Severe or rapidly worsening symptoms
  • Breathing difficulty, chest pain, fainting, confusion, severe weakness, major injury, or severe dehydration
Doctor / service to discuss: Qualified healthcare provider; specialist depends on symptoms and examination.
  1. Step 1

    Check danger signs first

    If danger signs are present, seek emergency care and do not wait for online information.

  2. Step 2

    Record the symptom story

    Write when symptoms started, severity, medicines already taken, allergies, pregnancy status, and test results.

  3. Step 3

    Visit a qualified clinician

    A doctor, nurse, or qualified healthcare provider can examine you and decide which tests or treatment are needed.

  4. Step 4

    Do only useful tests

    Do tests after clinical assessment. Avoid unnecessary tests, random antibiotics, or repeated medicines without diagnosis.

  5. Step 5

    Follow up and return early if worse

    If symptoms worsen, new warning signs appear, or treatment is not helping, return for review quickly.

Rural patient practical tips
  • Take a written symptom diary and all previous prescriptions/test reports.
  • Do not hide medicines already taken, even herbal or over-the-counter medicines.
  • Ask which warning signs mean urgent referral to hospital.

This roadmap is for education. A real diagnosis and treatment plan requires history, examination, and clinical judgment.
