Brain Fog - What It Is and What You Can Do About It

Brain Fog - What It Is and What You Can Do About It

Where did I park the car? Did I just email the wrong person? My brain feels like it’s stuck in slow motion…

Have you been hearing the term “brain fog” thrown around a lot lately? We have, typically accompanied by a sales pitch for expensive “nootropic” supplements loaded with exotic herbs with claims to improve your ability to think. Before you open your wallet, let’s discuss what “brain fog” really is (p.s. it’s not a medical diagnosis) and what you should do first to overcome it.

“Brain fog” is an umbrella term used for certain symptoms that can affect your ability to think and function mentally. For example, you may struggle with short-term memory, have difficulty focusing on a task and making decisions, or lack mental clarity and the ability to solve even simple problems.

While everyone will experience these symptoms from time to time, if you are struggling with your ability to think on a frequent basis it may be a sign of an underlying problem that should be addressed.

What Causes Brain Fog?

There are numerous factors that influence brain health and cognition, and while each case of “brain fog” is different, the following are the most common:

Inflammation and Oxidative Stress

Caused by an increase in free radicals (i.e. reactive oxygen species), inflammatory signals called pro-inflammatory cytokines (think infection, food sensitivity, gut imbalance), or a reduction in antioxidant capacity, your brain function can be negatively impacted.

Nutrient Deficiencies

Vitamins, minerals, and other nutritional substances play a role in cognitive function, and insufficient intake of these nutrients can lead to brain fog. Specific examples are discussed in the next section.

Prescription Medications

Benzodiazepines, statins, narcotics, anti-hypertensives, chemotherapy, and sleep aids may change brain chemistry and impact cognitive performance. Always consult your healthcare professional in regard to any concerns or changes to your medication.


The most prevalent example is menopause, which is accompanied by significant hormonal changes after which many women report brain fog.

Poor Sleep and Sleep Apnea 

Consistent, uninterrupted, and adequate length sleep is essential for brain function, yet is becoming harder to come by in the modern world.

Iron Deficiency With and Without Anemia

Red blood cells must deliver adequate oxygen to the body's tissues or a person may experience mental and physical tiredness, including brain fog. Even iron deficiency without anemia may cause cognitive disturbances.

What Can You Do?

1. Get The Correct Dosage of Vitamins and Minerals For Your Body

2. Sleep Better, Longer

  • Adults should sleep between 7-9 hours each night (we think 8 is the sweet spot) and aim to improve their sleep quality by reducing stress, going to bed at the same time each night, avoiding bright artificial lights in the late evening, lowering the temperature of their room (aim for the mid-60’s), and removing any light source from the bedroom.

3. Achieve A Healthy Weight

  • Excess weight is a risk factor for both sleep apnea and inflammation, so achieving a healthy weight is a huge step in the right direction.

4. Drink Enough Water

  • Dehydration is one of the most easily corrected source of brain fog. Get to sippin’!
