What Is Brain Fog?
Brain fog refers to a mild to moderate difficulty with focus, concentration, memory, and other cognitive functions. It can manifest in various ways, many of which are subjective and self-reported. You might feel mentally fatigued, struggle to find the right words, or experience a sense of being slow, spaced-out, or forgetful. Daily tasks can become challenging, conversations hard to follow, and concentration, mental clarity, and memory may decline. Recognizing brain fog often involves noting a combination of these symptoms.
Brain Fog Symptoms
If you’re experiencing brain fog, you might notice:
– Mental fatigue
– Forgetfulness
– Being easily distracted
– Poor memory
– Difficulty concentrating
– Feeling “spaced out”
– Disorientation
– Irritability
The Top 7 Causes of Brain Fog
Various factors contribute to brain fog, including hormonal changes, medication side effects, and normal aging. Here are the top seven causes:
Stress
Mental stress triggers your body to produce high levels of cortisol. Stress also suppresses your immune system and stimulates your adrenal system, leading to the release of hormones like cortisol, epinephrine, and norepinephrine. These hormones can impair working memory, concentration, and motivation, contributing to brain fog.
Poor Dietary Choices
Your diet significantly impacts brain efficiency. High-fat or sugary foods can impair memory and other cognitive functions. Processed foods, often marketed as healthy, may contain harmful preservatives, MSG, and excess sodium. For optimal mental performance, ensure a balanced intake of proteins, carbohydrates, healthy fats, and essential nutrients. Staying hydrated is also crucial as dehydration can cause headaches and reduce mental focus.
Allergies & Food Intolerances
Food allergies or sensitivities, especially to wheat gluten or dairy, can worsen brain fog. Gluten sensitivity, in particular, can manifest primarily as a neurological condition. Celiac disease, triggered by gluten consumption in sensitive individuals, causes digestive system inflammation that affects balance, concentration, and memory. Similarly, consuming dairy when lactose intolerant can impact the central nervous system and lead to brain fog.
Medications
Many prescribed and over-the-counter medications can reduce mental clarity. Drugs like benzodiazepines (used for anxiety), opiate pain medications, and sleep aids may exacerbate brain fog. Medication interactions, including those with over-the-counter products and supplements, can amplify these effects.
Health Conditions
Certain health conditions can impair cognition. Type 2 diabetes affects mental focus due to blood glucose level changes and emotional challenges like depression. Low thyroid function, Hashimoto’s disease, anemia, high blood pressure, and autoimmune disorders like lupus or multiple sclerosis are also linked to brain fog. Additionally, nicotine addiction from smoking or other tobacco products can contribute to brain fog, especially during withdrawal.
Inadequate Sleep
Physical fatigue and sleep deprivation are leading causes of brain fog. Poor sleep quality is often associated with cognitive decline, particularly in middle-aged adults. According to the U.S. Centers for Disease Control and Prevention (CDC), adults need seven to nine hours of sleep per night. Quality sleep boosts energy levels and mental clarity and supports overall body function.
Age-Related Hormonal Changes
Hormonal changes at certain life stages can cause brain fog. Women going through menopause may experience brain fog due to the decline in reproductive hormones. Common symptoms include trouble focusing, fatigue, and difficulty sleeping. Both men and women can experience age-related mental changes that manifest as brain fog.
How to Naturally Get Rid of Brain Fog
There are several natural ways to alleviate brain fog by supporting your body and brain:
Essential Oils
Inhaling essential oils can quickly send calming messages to your brain. Frankincense has been shown to improve memory and cognitive functions. Lavender, peppermint, and chamomile can relax and calm the mind, aiding in restorative sleep. Vetiver oil stimulates alertness, beneficial for learning and memory. Try adding a few drops of lavender oil to your hands, rubbing them together, and taking deep breaths.
Sleep More
Many adults don’t get the recommended seven to nine hours of sleep per night, leading to fatigue and decreased productivity. Healthy sleep hygiene practices, like maintaining a consistent bedtime routine, limiting naps, and avoiding caffeine and rich foods close to bedtime, can improve sleep quality.

Eat Healthy Fats
Healthy fats from nuts, seeds, and vegetables like olive oil, avocado oil, and walnut oil contain omega-3 fatty acids essential for brain health. These fats support the blood-brain barrier and help maintain healthy cholesterol levels. Avoid saturated fats from red meat and high-fat dairy, which can impair memory and cognition. Coconut oil is an exception, as it can lower bad cholesterol.
Eat Antioxidant-Rich Fruits & Vegetables
Antioxidants help memory and cognitive functions by counteracting free radicals that damage cells. They are abundant in dark green leafy vegetables, brightly colored fruits and berries, and spices like turmeric and cayenne pepper. Cocoa, rich in flavanols, also contains antioxidants that improve circulation and preserve cognitive abilities. A balanced diet with healthy carbohydrates and proteins is essential for brain health.
Exercise
Regular exercise protects against weight gain and stimulates hormone release, improving brain health, mood, and energy levels. A fitness routine combining aerobic exercise, strength training, and stretching can enhance memory, attention, and mental processing speed. Spending time outdoors also boosts cognitive development and benefits adults.
Brain Fog Supplements
While a healthy diet is crucial, supplements can provide an extra boost. Consider these supplements to support brain health:
Omega-3 Fatty Acids
Omega-3 fatty acids can slow mental decline and improve brain fog symptoms like working memory and information retrieval. While fish oil supplements are popular, they may contain contaminants. Plant-based sources like flaxseed oil or algae oil are recommended.
Magnesium
Magnesium deficiency is linked to brain disorders. This mineral supports neuron function, transmitting messages to the body and creating thoughts. Magnesium supplements can protect cognitive function and memory, reducing brain fog.
Maca Root
Maca root contains fatty acids that preserve brain health. Studies on mice have shown that maca root enhances memory and cognitive abilities by boosting cellular energy. Maca also promotes balanced mood and increases vigor and energy levels.
Vitamin B12
Low B12 levels can cause muddled thinking and forgetfulness. Supplements can slow age-related brain decline, especially in deficient individuals. Since B12 is mainly found in animal-based foods, vegetarians and vegans may need supplements. Global Healing’s Vitamin B12 offers a certified organic liquid with various B12 forms for sustained support.
Bacopa
Bacopa monnieri, used in Ayurvedic remedies, improves symptoms like short attention span, poor focus, and short-term memory. Bacopa normalizes cortisol levels, reducing stress and enhancing brain function. It also acts as an adaptogen, helping the body adapt to stress.
Mucuna pruriens
Velvet bean (Mucuna pruriens) contains antioxidants and L-dopa, a brain chemical that produces dopamine. Dopamine regulates processes associated with brain fog, including mental flexibility, memory, and motivation.
Iodine
Iodine is essential for metabolism and thyroid hormone production, which are crucial for energy and brain function. An iodine deficiency can lead to brain fog. Ensure adequate iodine intake for a sharp mind and balanced metabolism. Nascent iodine is the most efficiently absorbed form by the body.
Points to Remember
Brain fog is a common issue with symptoms like mental fatigue, poor memory, and lack of focus. It can be caused by stress, poor diet, medications, health conditions, inadequate sleep, and age-related hormonal changes. To reduce brain fog, adopt a healthy diet rich in antioxidant foods, exercise regularly, get sufficient sleep, and consider supplements like omega-3 fatty acids, magnesium, and vitamin B12. Herbal remedies like bacopa and essential oils like peppermint can also help clear the fog and improve mental clarity.
