What is Acetylcholine? Function & Facts (Updated 2022)

Acetylcholine is an essential neurotransmitter that assists with many different functions in the body. Acetylcholine plays a role in memory, learning, and problem-solving skills. It also impacts our ability to take action and respond to things quickly. Acetylcholine deficiency can lead to a number of issues, including difficulty focusing, slow response time, and poor memory.

Fortunately, there are natural ways you can boost your acetylcholine levels naturally. The more you know about this critical neurotransmitter and how it impacts your health, the better equipped you’ll be to keep your acetylcholine levels optimized. Let’s have a look at what are the various dynamics associated with this neurotransmitter. 

What is Acetylcholine?

Acetylcholine is responsible for facilitating communication between your neurons. More simply, Acetylcholine allows your brain cells to talk to each other. This chemical is also found in your autonomic nervous system, which is responsible for regulating your internal organs. Since Acetylcholine is so important for many bodily processes, it’s no surprise that deficiency is linked to a wide range of health issues.

Some of the most common problems associated with low Acetylcholine are memory loss, attention span loss, and the inability to respond quickly to outside stimuli. Acetylcholine is created in your body from choline, which is a water-soluble vitamin.

Benefits of Acetylcholine

Improved Focus and Attention Span: Acetylcholine is crucial for brain function, particularly your ability to stay focused. If you’re experiencing low acetylcholine levels, you may have difficulty focusing on one thing for long periods of time, as well as switching focus from one task to another quickly.

Improved Learning and Problem-Solving Skills: Acetylcholine also plays a role in your ability to learn new things and solve problems.

Improved Coordination and Reaction Times: Acetylcholine helps your nervous system respond quickly to stimuli in your environment. In addition, it is critical for transferring signals to your muscles, which impacts your ability to perform coordinated movements.

Improved Mood and Better Sleep: Acetylcholine is also known to impact your mood, as well as your sleep patterns.

How to Increase Acetylcholine Naturally?

If you’re experiencing low acetylcholine levels, you can boost your Acetylcholine naturally by eating foods that are rich in choline, as well as other nutrients that support acetylcholine levels.

1. Eggs


Eggs are one of the richest sources of choline, which makes them an excellent option for boosting Acetylcholine naturally. One large egg contains approximately 250 mg of choline, which is about half of the daily recommended intake. You can enjoy eggs in a number of different ways, including hard-boiled, scrambled, and fried.

2. Dairy Products

Dairy Products

Milk and other dairy products are also excellent sources of choline. One cup of skim milk contains approximately 300 mg of choline, which is approximately half of the daily recommended intake.

3. Fish


Fish is also high in choline, as well as another critical nutrient needed to produce Acetylcholine. One serving of fish, especially sardines, mackerel, and salmon, provides approximately 500 mg of choline.

How to Boost Your Acetylcholine with Supplements?

If you notice that your acetylcholine levels are very low, you may want to use supplements to boost your Acetylcholine naturally. Always speak with a healthcare professional before taking any supplements, as they may interact with your other medications.

Choline Supplements: There are two different types of choline supplements, including choline bitartrate and choline citrate. While choline supplements are widely available, there isn’t a lot of research to prove they boost Acetylcholine effectively.

Acetylcholine Precursors: Acetylcholine precursors are natural substances that have been shown to boost acetylcholine levels. Acetyl-L-Carnitine (ALCAR) and Citicoline are two common acetylcholine precursors.

Herbal Supplements: Certain herbs have been shown to support acetylcholine levels, including Rhodiola Rosea, Ginkgo Biloba, and Gotu Kola.

What is the Importance of Acetylcholine? 

Acetylcholine (ACh) is a neurotransmitter that has many functions, including memory, learning, and cognition. ACh is critical for normal brain development and functioning and maintaining the healthy structure and function of the peripheral nervous system. It is released from the brain’s vagus nerve and nerves in the gastrointestinal tract and other organs.

In the brain, ACh acts as a messenger between neurons to transmit information from one brain region to another. It also plays an important role in regulating involuntary body movements such as eye blinking, chewing, or swallowing. In addition, ACh is involved in the regulation of emotions, moods and memory.

In some people with ADHD, there may be problems with ACh levels that may contribute to their symptoms of inattention and hyperactivity. Low levels of ACh can lead to problems with coordination and fine motor skills (e.g., difficulty holding a pencil), while high levels may cause problems with attention (e.g., difficulty focusing).

Changes in ACh levels can also be observed using brain imaging techniques such as positron emission tomography (PET) scanning and functional MRI (fMRI). These tests can show whether there are changes in blood flow or activity in certain parts of the brain associated with ADHD when compared to controls. 

Conclusion: Understanding Acetylcholine

Acetylcholine is an important neurotransmitter that facilitates communication between nerves and muscles. When you have a healthy level of Acetylcholine, you can expect to have increased cognitive function, better memory, improved mood, better sleep, and improved coordination.

The best way to maintain healthy levels of Acetylcholine is to eat a well-balanced diet that includes natural sources of choline, such as eggs and dairy products. You can also boost your Acetylcholine naturally with certain supplements, including choline supplements, acetylcholine precursors, and herbs.
