What Is Choline, Exactly?

Choline is a vitamin-like compound necessary for many body functions, including normal brain development and operation. It's also essential for heart health and cell structure. Choline deficiency can cause serious health problems, but is it something you should worry about? Let's take a look at what Choline is—and isn't!

Choline definition

Choline is a water-soluble vitamin, which means it can be found in many foods, including eggs and other animal products like meat and seafood. It's also naturally synthesized by your liver and kidneys.

Choline helps form cell membranes, aids in many bodily functions (including muscle movement), and is a precursor to acetylcholine—a neurotransmitter that sends signals between nerve cells. It would help if you had Choline to make DNA; break down fat; metabolize carbohydrates; produce red blood cells; regulate hormones like estrogen and testosterone; maintain healthy skin, hair, and nails; support the immune system; protect brain function as you age; keep your nervous system healthy by producing fatty acids called phospholipids that help maintain healthy nerve cell membranes; convert food into energy, so you have more energy throughout the day.

How does Choline work in the body?

Choline is a precursor to acetylcholine, which is an important neurotransmitter. Acetylcholine plays a role in learning and memory, muscle movement, and sleep.

In other words: it's pretty crucial!


If you're thinking about taking Choline, it's essential to know what form of Choline you need. The most common forms are:

  • Alpha GPC Choline (Alpha-Glycerylphosphorylcholine) is a naturally occurring compound derived from soy or egg yolks and is very high in bioavailability.

  • Choline Bitartrate is considered the least expensive form and is water soluble.

  • CDP Choline can cross the blood-brain barrier more quickly than other forms of Choline and will help increase uridine levels in your body, increase serotonin production, helping with mood disorders like depression or anxiety attacks.

Choline dosage and side effects

Your Choline dosage depends on your current health status and medical history.

For most people, the recommended daily intake is 550 milligrams per day for men and 425 milligrams per day for women. For moderate supplementation, a higher dose of 1000 mg is often used to treat memory loss or help reduce the symptoms associated with Alzheimer's disease. If you want to get serious about an intense cognitive focus regimen, some people recommend taking up to 3 grams (3,000 mg) at once—but this can cause side effects like nausea, vomiting, and diarrhea.

Eggs yolk and choline sources

Choline is a B vitamin essential for various bodily functions and plays a vital role in the brain, liver, and kidneys. Choline is found in many foods, but egg yolks are one of the richest sources. Other good sources include liver and fish such as salmon or trout. Meat (including beef), broccoli, spinach, and cauliflower are also good sources of Choline. Beans like kidney beans or lentils contain some choline too!

Are children adequately nourished?

It's easy to see that Choline is essential for brain development, but it's also crucial for the health of many other organs in the body. The liver and heart need a lot of Choline to do their jobs properly, and so does every cell in your body.

The bottom line is that we're not getting enough of this essential nutrient. It's clear from the research that children are not getting enough Choline, which could be hurting their overall health—and their ability to learn and grow as they should.

Cognitive performance

Choline is a precursor to acetylcholine, which is an important neurotransmitter. Acetylcholine plays a role in memory, cognition, and muscle movement. It also plays a vital role in brain development during pregnancy and infancy.

Liver health

Choline is essential for liver health because it's involved in synthesizing phosphatidylcholine, a substance that helps maintain the integrity of cell membranes in your liver. It also plays a role in metabolizing alcohol and maintaining proper brain function. Choline is also necessary for several aspects of heart health, including nutrient absorption, blood

cholesterol levels, and body fat distribution throughout the body. Without enough Choline, you may experience irregular heartbeat or other cardiovascular problems.

Additionally, Choline impacts kidney function by helping to prevent the buildup of excess lipids (fats) within them, leading to kidney disease if left untreated over time. Finally—and perhaps most importantly—Choline plays a crucial role in pancreatic health by facilitating digestion and absorption of fats from foods like eggs or fish oil supplements like Omega-3s capsules.

Choline is an essential nutrient. There are many good food sources of Choline, but you might need a supplement to ensure you're getting enough

Choline is an essential nutrient that your body needs to function correctly. It's found in many foods, but you may need a supplement to ensure you get enough.

Choline is an essential nutrient your body needs to function correctly and keep the liver healthy. It also helps with cognitive performance, memory, and brain development in infants and children.

Suppose you eat a varied diet containing adequate amounts of choline-rich foods (such as eggs). In that case, it's unlikely that you will need a choline supplement on top of this—but some people require extra supplementation because they have trouble absorbing Choline from food sources or because their bodies don't produce enough on their own (like pregnant women).


Choline is an essential nutrient, so it's important to get enough of it. The best food sources are eggs, liver, and fish, which also have other health benefits. If you need to take a supplement, ensure it has the correct dose for you and doesn't contain harmful ingredients like lead or mercury.
