You’re in the middle of your conversation or a task when suddenly, you forget what you’re doing or what you were talking about. A bit like your brain is short-circuiting. Then you space out completely and feel like you’re walking through jello. Sound familiar? There might be a chance that you’re experiencing brain fog. Here is what you need to know about brain fog.

Brain Fog: Is It Serious?

What Is Brain Fog?

Brain fog is a term used to describe mental exhaustion. Depending on the severity, it may have an effect on your success at work or education. Brain fog is undeniably frustrating: you know you can do exceptional work, but not having mental focus can feel like you’re running in slow motion.

Brain fog itself is not a medical condition but rather a symptom. This is a kind of cognitive dysfunction involving:

  • Inability to focus
  • Lack of mental clarity
  • Poor concentration
  • Memory problem


Causes and Treatments for Brain Fog

Low Thyroid Function

When you don’t have enough thyroid hormone, your metabolism slows, decreasing blood flow to the brain and resulting in poor energy output. In addition, it also boosts the production of the stress hormones cortisol, suppressing thyroid function even further. As a result, you will experience brain fog, fatigue, weight gain, and potentially hypothyroidism.

Solution: have your thyroid tested 

If you’re feeling more tired than usual, the first move is to see your doctor and have your thyroid checked. You may have subclinical hypothyroidism even though tests prove you’re not hypothyroid.


Poor Blood Sugar Control

If you’re having brain fog after two to three hours after a meal, you’re likely to have consumed too much refined carbohydrates such as pasta, baked goods, bread, and other refined flour products.

The initial spike in blood sugar induces a large spike in insulin, which causes cortisol to be released, resulting in low blood sugar. Blood supply to the brain is restricted as a result, leaving you exhausted and foggy. Also, low blood sugar levels can have the same effect.

Solution: watch what you eat 

Substitute refined carbohydrates with complex carbohydrates and include protein in your diet. Protein like chickpeas, seeds, eggs, yogurt, cheese, meat, fish, seeds, nuts, and beans. Complex carbs include whole grain like buckwheat, quinoa, millet, starchy vegetables, and fruit.

This will delay the delivery of glucose to the body, providing you with more consistent and long-lasting energy.


Antibiotic Use

Certain classes of antibiotics mainly including fluoroquinolone antibiotics are notorious for leading to permanent brain fog by disrupting neuronal firing in the brain. These antibiotics can lead to oxidative stress in a similar fashion to Alzheimer’s thus reducing concentration and mental focus. In a scientific study published in the American Academy of Neurology, drugs like metronidazole (flagyl) Ciprofloxacin (Cipro) and Fluconazole (Diflucan) all led to abnormal brain scans, delirium, and mental confusion.

Solution: seek a functional medicine doctor

They can determine if your brain fog may have been caused by antibiotic use.



Candida overgrowth in the gut is a major cause of brain fog. Candida is a fungus that is normally found in small amounts in our GI tract. However, sometimes we have candida overgrowth which can be triggered by the use of antibiotics which can kill off our normal required gut bacteria thus leading candida to thrive. Excessive intake of carbohydrates, sugar, and alcohol can also feed candida leading to overpopulation in the gut. When Candida grows out of control, the liver is not able to properly metabolize neurotoxins like alcohols and aldehyde which accumulate in the brain leading to brain fog.

Solution: reduce sugar intake

Reducing sugar and high carb intake diet can reduce the amount of food that candida can eat. Caprylic acid has also been shown to break down candida cell walls.



Long-term stress can cause Adrenal Dysfunction, in which the adrenal glands produce too much or too little of the stress hormone cortisol. This can result in your brain fog. The increased cortisol will suppress thyroid function, blocking progesterone production and raising estrogen while restricting your brain blood circulation, leading to a reduction in the number of nutrients and oxygen delivered to the brain.

Solution: reduce your stress, limit your alcohol

There is a ton of ways for you to get your stress level under control, including:

  • Yoga and meditation
  • Exercising regularly
  • Breath deeply
  • Spend time with your friends and family, or your pets
  • Listen to music
  • Chew gum
  • Eat chocolate
  • Use a stress ball
  • Stretching
  • Counting backward



One of the first organs to show signs of dehydration is your brain.

In fact, even a 2% dehydration can affect mental function, memory development, and concentration. Drinking water can be your first port of call if your fogginess comes and goes during the day.

Solution: stay hydrated

Cut soda and unnecessary high fructose corn syrup drinks, it does not hydrate the body or serve any positive impact for the brain. Drinking 2L of water a day per study showed the potential of lowering blood pressure, increasing body temperature, diluting blood waste materials, and protecting kidney function. Thus, increasing daily water intake could also provide several health benefits.



Sleep deprivation can result in hormonal imbalances, which can lead to brain fog.

It also increases the stress hormone cortisol, which decreases the development of the neurotransmitter dopamine, rendering you irritable and unmotivated.

Solution: get enough sleep 

At least 8 hours of sleep every night.


Neuro Spark vs. Brain Fog

Neuro Spark by Regen Labs reduces oxidative stress, which is believed to play a role in the development of brain fog. Intellect decreases brain fog and improves memory by removing amyloid-beta plaques, which are usually found in Alzheimer’s patients.


Neuro Spark – 3 Top Ingredients

The NINE ingredients in Regen Labs’ Neuro Spark have been shown to catalyze higher brain activity and increase memory.

One of Neuro Spark’s ingredients, bacopa, is an ancient herb that is shown to boost your brain function, improve cognition, memory and commonly used to treat ADHD.

Trans Ferulic acid can support memory and learning problems and show notable antioxidant effects while looking after the surface structure of the hippocampi.

Centrophenoxine, another key ingredient in Neuro Spark, is a compound that helps your brain store memory and regulate many brain functions such as learning, attention, alertness, and memory.
