Does Choline Help Prevent Dementia and Alzheimer’s?

In This Article

First of all I want to tell you, I’ve been taking Choline in the mornings and my brain is on overdrive during the day. I feel sharp! You need to know about this…Does Choline Help Prevent Dementia and Alzheimer’s? Let’s find out. 

A new report came out in September 2019 on a recent study done by Arizona State University (ASU) about the nutrient choline. The research shows choline is a remarkable player in the battle against dementia and Alzheimer’s. It seems very promising for some of the aspects of dementia and Alzheimer’s and may indeed help prevent neurodegenerative diseases.

As discussed in other articles here, dementia and Alzheimer’s disease (AD) have multiple causes and symptoms. There isn’t just one thing you can do to either prevent or treat them. It’s a multi-pronged approach. You should also know that AD is a form of dementia, so when we talk about dementia, we’re also talking about AD.

Some other information came out in August 2019 that dementia and AD are the leading causes of death in England and Wales. Some blame the lack of recommendations for choline throughout life, in fact (Arizona State University [ASU], 2019). This news is quite disheartening and also quite surprising.

What is Choline?

It’s actually vitamin B4. ASU (2019) states that all plant and animal cells require choline in maintaining their structural integrity. Choline is synthesized into acetylcholine, which is a neurotransmitter. Obviously, this is a crucial component of the nervous system and brain. 


Choline has some other great functions. One is it helps with non alcoholic fatty liver by helping metabolize lipids and cholesterol. Choline also acts as a controlling step of cholinergic neuronal activity (Inazu, 2019). In Alzheimer’s patients, the decrease in number of neuronal cells is significant.

Many people report having significantly improved brain function during the day when taking choline. And also recommend not taking it at night as it keeps the brain working overtime. 

How Does Choline Prevent Cognitive Decline?

The blood-brain barrier protects our brains from the ‘bad stuff’. It’s a gatekeeper, so to speak. Only required nutrients make it past the blood-brain barrier.  Likewise, substances not needed or waste are excreted through the blood-brain barrier. Choline is one of those nutrients that can pass through. It’s needed to make acetylcholine which is responsible for cholinergic nerve activity (Inazu, 2019).

Cholinergic nerves are responsible for higher order functions in the brain such as sense and recognition, motion, memory, and learning. Cholinergic nerves are mostly found in the cerebral cortex. As you can see, some of these are features of dementia and Alzheimer’s. In fact, researchers have found that functional depression of cholinergic nerves in Alzheimer’s patients is an “essential state of the disease”, (Inazu, 2019). In other words, the cholinergic nerves aren’t functioning well or there are fewer of them.


The Effects of Choline Deficiency

Lack of acetylcholine in the central nervous system affects memory, memory retention, and spatial cognition in the hippocampus. 

Another function of choline is helping the brain get rid of debris without tipping off the microglia to go into overdrive. 
Microglia are specialized cells that rid the brain of deleterious debris.
(ASU, 2019)

If the microglia are overactivated, the brain starts forming amyloid plaques in an attempt to protect itself (in error). The plaques cut off the normal flow of the brain and the beginning of dementia and Alzheimer’s starts or continues. Choline, formed into acetylcholine, helps reduce the amount of microglia so it doesn’t get out of control. This is how it prevents dementia and Alzheimer’s.

How Do I Get Choline?

The good news is that choline is in several foods and not hard to get. It can be found in:
  • Eggs (with yolk) (147mg)
  • Chicken liver (3 oz; 247mg)
  • Grass-fed beef steak (3oz; 55mg)
  • Wheat germ (1oz toast; 51mg)
  • Milk (8 oz; 38mg)
  • Brussels sprouts (1/2 cup; 32mg)

If you either don’t like these foods or are a vegetarian or vegan, you might consider a supplement

The suggested intake for adult women is 425/mg/day and 550mg/day for adult men. However, ASU states this may not be enough to prevent Alzheimer’s so you could eat or take more than that. The upper safe limit is 3500mg/day. 

As you can see, it might be hard to get the recommended or extra amounts needed from food alone. 

I’m including these to make it easier for you. Don’t waste any more time to start supplementing choline today. You will improve your mental clarity and thinking almost immediately.

Where We Are Now.. 

We’ve discovered that choline is needed by every cell in the body. It’s also needed in the brain to synthesize acetylcholine, a neurotransmitter. This neurotransmitter keeps the microglia count down and helps avoid amyloid plaques, a feature of dementia and Alzheimer’s. Choline deficiency is a precursor to poor memory, reduced spatial skills and cognitive decline.

It has recently been found that choline has a direct relationship with brain function and the risk of developing neurodegenerative diseases. While we can get some choline from foods, it’s not enough to prevent those devastating diseases. Scientists recommend supplementing the diet with choline for a lifetime.
This is a great daytime supplement. Your brain will go into overtime. If you are just looking for something to make you feel sharp, this is it.
I hope you learned some things about choline. With the recent studies published, it’s exciting to know more brain discoveries are being made.

  1. Hello Paula,

    This article is very informative. I learned a lot from it. My grandma is suffering form dementia. So it’s always a good thing to learn something new about dementia and AD. It says that dementia is genetical. Could you please tell what your thoughts on that matter?

    As you have mentioned, the upper safe limit of choline intake is 3500mg/day, then we really need to take some supplements. So thank you for recommending what are the good choline supplements out there in the market. 

    • HI Anjali, I’m sorry to hear about your grandmother. Actually, there is a gene that can lead to Alzheimer’s and dementia, APOE-4 but just because a person has the gene doesn’t mean they will get Alzheimer’s or dementia. That’s another reason why it’s good to read and find out how to curb your chances of getting it. I believe choline is one of many things a person can take and do. 3500 mg is the most you would want to take and it’s really not necessary to take that much. It just means you can take a Lot before you’d have any ill effects from it. Take care!

  2. Who would’ve thought that choline is that important in the human system. I do not have constant dementia or anything like that but it is always very good to have a new learning curve everyday. Seeing that it is related to my bones and I am getting old. This Isa time when I need stuff like this. I have to get one of this supplements you have written here ASAP so I can get my choline levels up. Great educative post. Keep up with the good work.

    • Thanks, Henderson. Since it actually helps the entire body, it’s a good idea to at Least eat the foods higher in choline. It will also prevent memory and dementia issues so it’s never too early to start. You don’t want to wait. 

  3. Wow Paula. Your article on Choline has gotten me very excited. I’m reaching the age where dementia and AD are becoming a real possibility. I can see by the figures you include in you blog that trying to get the correct dosage from food alone is not going to be enough. I might be reading to much into it but lately my memory is getting worse. This could be because of stress or it could be a lack of Choline.  Do you think that it would be okay to take the supplement as well as the correct food requirements. I guess what I’m asking is can I get to much choline in my system. Thanks Jim

    • Jim, thanks for commenting and reading. Actually, they say the safe upper limit is 3500 mg a day so I think you’d be okay to eat the choline foods And supplement. I hope you enjoy the increased memory power. 🙂

  4. This is pretty interesting here because i don’t think i have ever heard about choline before. It is truly very important that one has this in the body system. One thing i am somewhat baffled about is that we are never told all of this from when we are young. Self-research is very good i guess. I have to thank you seriously for this wonderful educative show here. I am also going to share your post because it is of value to people. Are there any side effects of taking those supplements?

    • Hi. Thanks for reading and commenting. I haven’t heard of any side effects at all. I think we didn’t know about it when we were young because they just didn’t know about it yet. This research I wrote about is really new. 🙂 Thanks again for commenting. I appreciate you sharing it also.
