7 Brain Fog Causes (And How to Cure It)

Brain Fog Man At Computer

Brain fog is perhaps the most annoying medical condition there is. Despite it affecting millions of Americans, nobody seems to talk about it. Brain fog is annoying, too – even just a small reduction in cognitive function can make it hard to focus and be productive.

So, what are you supposed to do if you have brain fog? The answer isn’t simple, because it depends on the cause of your brain fog. There are several different causes we will go over.

Today’s article will focus on:

  • What is Brain Fog?
  • What Causes Brain Fog?
  • How to Treat Brain Fog?
  • Can You Ever Eliminate it Entirely?

So, if you want to reclaim your mental clarity, improve memory, decrease depression, and increase the overall health of your brain, then keep on reading.

What is Brain Fog?

First off, it’s important to note that brain fog is not a medical condition, but rather a symptom or series of symptoms, suggesting that there is another underlying cause.

Symptoms of brain fog include:

  • Cognitive Impairment
  • Mental Fatigue
  • Memory Problems
  • Inability to Focus
  • Feeling Fuzzy & Unclear

Most people describe brain fog as just being unable to focus or really think clearly, and thankfully, for the most part, it’s a fairly easy fix.

What Causes Brain Fog?

There are several different reasons why brain fog may occur. Some of them are more common than others, but the root cause of brain fog is your brain’s neurotransmitters are off balance.

Let’s explore a few of the causes of brain fog, so you can determine the best solution.

1. Lack of Acetylcholine

The biggest cause of brain fog by far, is a lack of acetylcholine in the brain. Due to mono-cropping, and GMO’s, among other things, many of the foods we consume nowadays do not have enough vitamins or minerals in them.

This means your brain has a nutrient deficiency by default, unless you’re proactively seeking out healthy, organic foods – and even then, it’s still very difficult to get all the nutrients your brain needs.

Acetylcholine is a critical neurotransmitter, important for:

  • Learning and Memory [R]
  • Attention & Focus [R]
  • Anti-Inflammation [R]
  • Circadian Rhythm [R]
  • …and much more

Many people who experience brain fog or chronic fatigue syndrome can improve their symptoms by simply taking a compound that boosts acetylcholine production.

Limitless Focus was designed to do this in a safe and effective way, that naturally increases your brain’s acetylcholine levels, without making you dependent on it.

Acetylcholine is critical to a large number of bodily functions and brain functions, so it’s not something you want to skip out on.

2. Dehydration

Dehydration is another leading cause of brain fog. They say that your body is 70% water, which means that even a small amount of dehydration will have a big impact on your health.

In fact, according to one study, just losing a mere 2% of the water in your body (which is equivalent to mild dehydration) can impair your overall cognitive function, lower your attention span, and decrease your memory. [R]

So, if you’re experiencing brain fog, research suggests pounding some water can help.

3. Chronic Stress

Stress is another common cause of brain fog, especially in our modern world. Everything is interconnected 24/7 these days, and it can be hard to get a little break when you need one.

Chronic stress can not only cause cognitive impairments but also:

  • High Blood Pressure
  • Memory Loss
  • Sleep Deprivation
  • Mental Fatigue
  • Hormonal Changes
  • …and more

It’s critical you learn to manage stress if you want to avoid brain fog. Consider things like exercise, going for a walk, meditation, eating a healthy diet, and more to combat stress.

4. Diet

Certain foods may trigger your brain fog, depending on your own food sensitivies and allergies you may have. Research shows that your diet is intimately connected with how well your brain functions, hence point #1 about acetylcholine.

Your diet can make or break you – if you’re consuming lots of foods with high carbohydrates, this can lead to a crash in glucose which worsens brain fog. In general, eating a poor diet with nutritional deficiencies is enough to cause terrible brain fog on its own.

Instead, try instituting the following guidelines:

  • Eat Lots of Healthy Fats
  • Minimize Carbohydrate Intake
  • Avoid Alcohol & Drugs
  • Eat Organic, Whole Foods
  • Consume A Protein-Rich Diet
  • Eat A Lot of Vegetables

For many people, improving your diet, getting enough sleep, and following general health guidelines is enough to improve brain fog, while also lowering risk of heart disease and more.

5. Lack of Sleep

Sleep is absolutely critical to brain function, and we’ve known this for years. Your sleeping habits will make you or break you, either leading to more mental clarity if you get enough, or mild cognitive dysfunction if you don’t get enough.

In fact, according to research, getting adequate sleep is one of the most critical things you can do for overall health. Sleep plays a role in nearly everything, such as:

  • Cognitive Function [R]
  • Mental Health [R]
  • Immune System [R]
  • Digestive System [R]
  • Depression & Mood [R]
  • Preventing Mental Decline [R]

If you want to maximize your brain health, supercharge your central nervous system, reduce brain fog, and ensure your body function is at its highest, then aim to get 8-9 hours of sleep each night.

6. Hormonal Changes

Brain fog can also be caused by hormonal changes and dysregulation in the body. Many people with thyroid disorders, for example, report chronic fatigue syndrome as well as brain fog.

Most hormonal health conditions can be improved by simply following the advice in this article (get enough sleep, eat enough, get enough exercises), but in some persistent cases, taking medication may be required.

Here are some healthy and easy ways to regulate your hormones:

  • Reduce Stress
  • Get Enough Sleep
  • Take Cold Showers
  • Regular Exercise
  • Organic Diet
  • Avoid BPA’s

While hormones can definitely cause brain fog, it’s not the most likely reason. Usually, brain fog is caused by poor sleep, poor diet, or poor lifestyle, and hormones just reflect this.

7. Medical Conditions

Lastly, certain medications and medical conditions may cause brain fog, low energy, and other symptoms, so always double check with your healthcare provider about all available treatment options, and any potential side effects.

Here are some medications known for causing brain fog:

  • Antianxiety drugs
  • Cholesterol drugs
  • Antiseizure drugs
  • Antidepressant drugs
  • Narcotic painkillers
  • Parkinson’s drugs
  • Hypertension drugs
  • Sleeping aids
  • Incontinence drugs
  • Antihistamines

If you’re taking any of these medications, keep in mind they may interfere with proper brain function, maintenance of brain cells, and more. Consider talking to your doctor if you’re taking one of these medications and experiencing brain fog.

How to Get Rid of Brain Fog

The easiest and fastest way to get rid of brain fog (or at least improve it) is to take a supplement that boosts acetylcholine levels and naturally regulates and balances your neurochemistry, like Limitless Focus.

Limitless Focus contains 11 clinically researched ingredients:

  • Turmeric Extract [R]
  • Barley Extract [R]
  • Schisandra Extract [R]
  • Bitter Orange Extract [R]
  • Caffeine [R]
  • Vitamin B1 [R]
  • Vitamin B6 [R]
  • Vitamin B12 [R]
  • Choline DMAE [R]
  • Taurine [R]
  • Glycans [R]

These ingredients work synergistically to boost focus and brain health in a natural way, while also alleviating some of the issues which may cause brain fog, among other issues, such as a brain chemical deficiency (especially acetylcholine or dopamine).

In addition to supplements which may help treat brain fog, you can also:

  • Get Enough Sleep
  • Eat Healthy Foods
  • Reduce Anxiety & Stress
  • Daily Physical Activity
  • Practice Mindfulness & Meditation

Most people have already tried most of the basics like this, however, which is why we recommend if you’re already doing this, you start supplementation as well.


In conclusion, brain fog treatment is relatively simple and easy. While it’s no fun to experience cognitive dysfunction, memory issues, and “brain fuzziness,” thankfully, treatment is simple.

Get enough sleep, eat a good diet, exercise regularly, and if that doesn’t work, consider supplementing with clinically researched compounds to improve brain health.
