Choline. You’ve probably heard of it, but have you ever stopped to wonder just what it does for your body?
Choline is one of those nutrients that doesn't always get the attention it deserves. Most people are aware of vitamins and minerals like vitamin C or calcium, but choline often takes a backseat in conversations about nutrition.
The truth is choline plays a very important role in many of our body’s most important functions. It supports brain health and even helps the liver do its job better. But despite its importance, many people aren’t getting enough of it.
Today, we’ll explain everything you need to know about choline, its benefits, the right dosage, the best food sources, and its associated risks.
If you’ve ever wondered, “What is choline good for” or “What happens if I don’t get enough choline?” this is the place to find your answers.
Let's get into its details.
Key Takeaways
- Choline supports brain function and liver health.
- The body can produce some choline, but it’s best to get it from food sources.
- A deficiency in choline can lead to memory problems and liver damage.
- You can find choline in foods like eggs, fish, and chicken.
What is Choline?
Choline is an essential nutrient that benefits various bodily functions. It’s often grouped with the B vitamins because it supports many processes similar to those of other vitamins in the B family. But despite its importance, the body doesn’t produce enough choline on its own, therefore, we need to obtain it from food sources or supplements.
Choline is involved in maintaining cell structure, transmitting nerve signals, and supporting metabolic functions. It’s especially important for brain health, as it helps produce acetylcholine, a neurotransmitter that supports memory and muscle control. Without enough choline, your body may struggle to carry out its basic functions effectively.
Why is Choline Important?
Choline is essential for several important functions in the body. It supports the structure of cell membranes and helps cells stay intact and function properly. This nutrient also supports the production of acetylcholine, a neurotransmitter that is involved in memory, mood, and muscle control.
Without adequate choline, the body struggles to maintain normal liver function. This can lead to liver damage over time. Choline also has an impact on brain health, particularly in fetal development and early childhood.
For adults, having enough choline can improve cognitive function and support long-term memory. It is safe to say that without choline, many vital bodily functions wouldn’t be able to work properly.
Benefits of Choline
Choline offers many benefits for the body, so ensuring you get enough of this essential nutrient can make a significant difference in almost every area of your health.
Here’s a closer look at some of the key benefits of choline:
1. Supports Brain Health
Choline is essential for producing acetylcholine, a neurotransmitter that helps with memory, mood, and muscle control. Adequate choline intake supports cognitive function and has been linked to improved memory and focus.
2. Improves Liver Function
The liver relies on choline to process fat. Without enough of it, fat can build up in the liver, leading to liver damage and conditions like fatty liver disease. Consuming enough choline helps maintain a healthy liver and prevents these issues.
3. Promotes Healthy Pregnancy
Choline is essential during pregnancy. It supports fetal brain development and may reduce the risk of birth defects. Pregnant women are advised to increase their choline intake to help ensure the healthy development of their baby’s brain and spinal cord.
4. Supports Muscle Function
Acetylcholine, produced with the help of choline, is essential for muscle movement. Without it, your body might struggle to coordinate muscle contractions, potentially affecting movement and strength.
5. Heart Health
Choline also helps to manage homocysteine levels, an amino acid linked to heart disease. The right balance of choline can therefore help lower the risk of cardiovascular problems.

How Much Choline Do You Need?
The amount of choline you need depends on your age, sex, and whether you are pregnant or breastfeeding. For most adults, the recommended daily intake ranges from 425 mg to 550 mg. Pregnant and breastfeeding women require more, with the recommendation going up to 550 mg and 500 mg, respectively.
Children also need varying amounts based on their age. The general guidelines suggest that younger children need between 125 mg and 375 mg of choline per day.
It’s important to note that getting enough choline can be a challenge for some people, as many diets don’t provide the necessary amounts. So in some cases, taking a supplement may be the best way to ensure you’re meeting your daily choline requirements.
Choline Deficiency

A choline deficiency can have serious effects on your health. When you don't get enough, your body struggles with some basic functions. One of the most common problems is liver damage. Without adequate choline, fat begins to build up in the liver, and this can lead to a condition called nonalcoholic fatty liver disease.
Another issue that may arise is cognitive decline. Low levels of choline may lead to memory problems and difficulty concentrating. People with low levels of choline may also experience muscle damage or weakness.
In some cases, insufficient choline during pregnancy can increase the risk of birth defects related to the brain and spine. If you think you're not getting enough choline, it may be time to adjust your diet or consider supplements.
Food Sources of Choline
To ensure you’re getting enough choline, it’s important to know where to find it in your diet. Fortunately, several foods contain significant amounts of choline, and they can easily be included in your meals.
Here’s a list of some of the best sources of choline:
- Eggs: Eggs are one of the richest sources of choline, especially the yolk. Just one large egg provides about 147 mg, which is nearly 30% of the recommended daily intake.
- Beef Liver: Beef liver is packed with choline, and it offers over 400 mg per 3-ounce serving. This makes it one of the most potent sources of choline.
- Chicken and Turkey: Poultry, especially chicken and turkey, are great sources of choline, with a 3-ounce serving containing about 70 mg.
- Salmon: This fatty fish provides a good amount of choline, with around 56 mg per 3 ounces. It’s also a great source of omega-3 fatty acids.
- Soybeans: For vegetarians and vegans, soybeans are an excellent choice. A cup of cooked soybeans contains about 280 mg of choline.
- Brussels Sprouts: These vegetables are a surprising source of choline. A half-cup of cooked Brussels sprouts provides around 32 mg.
- Potatoes: A medium-sized baked potato contains approximately 20 mg of choline, so it is a good addition to a balanced diet.
Potential Risks and Side Effects of Choline
While choline is important for health, it’s also essential to be aware of the potential risks of taking too much. Although it is uncommon for most people to experience negative effects from food sources of choline, high doses of choline in some supplements can cause problems like:
- Body Odor: Excessive choline can lead to a fishy body odor. This happens because the body breaks down choline into trimethylamine, a compound that has a strong odor.
- Low Blood Pressure: High amounts of choline may cause a drop in blood pressure. This can lead to symptoms like dizziness or lightheadedness, especially if you already have low blood pressure.
- Gastrointestinal Issues: Too much choline can cause nausea, vomiting, and diarrhea. These symptoms are typically seen in people taking large doses of supplements rather than those relying on food sources.
- Heart Problems: Some studies suggest that taking very high doses of choline may be linked to an increased risk of heart disease. This is especially true for people with certain genetic conditions, though more research is needed.
To avoid these risks, it’s best to stick to the recommended intake and avoid taking large amounts of choline from supplements unless advised by a healthcare provider. For most people, the most beneficial and safest way to get choline is from food sources.
How Much is Too Much?
It’s possible to have too much choline, especially if you rely on supplements rather than food sources. The recommended upper intake limit for adults is 3,500 mg per day. This is a large amount, and most people will never reach this level through food alone.
Excessive choline intake can lead to negative effects, such as the ones mentioned earlier, like body odor and gastrointestinal issues. To avoid these risks, it’s important to stick to the recommended daily intake of choline from food sources and use supplements cautiously.
If you're considering taking a choline supplement, it’s a good idea to consult with a healthcare professional to make sure you’re taking the right amount for your needs.
Conclusion
Choline is an essential nutrient that supports several important bodily functions like brain health, liver function, and muscle control. Despite its importance, many people don’t get enough choline through their diet. But ensuring you consume enough can help support mental clarity, prevent liver damage, and promote healthy brain development, especially during pregnancy.
Luckily, there are plenty of foods that contain choline, such as eggs, liver, chicken, and soybeans. If you're concerned about not getting enough, supplements may help, but it’s always best to aim for whole food sources first.
As with anything, balance is important. Getting too much choline can cause unwanted side effects. Aim to meet your daily needs and maintain a healthy diet to reap the full benefits of this essential nutrient.
