Brain fog is a common problem that can affect anyone at any time.

Many people are looking for an answer to the question: “What is the best medicine for brain fog?”

Unfortunately, there is no one-size-fits-all answer to this question. The best medication for brain fog will vary from person to person.

In this article, we will explore the different types of remedies that may help improve brain fog and discuss the best way to get each option.

We hope that this information will help you make an informed decision about which remedy is right for you.

Let’s get started.

What is brain fog, exactly?

Brain fog or mental fog is a term that refers to mental perplexity, fatigue, and forgetfulness.

It can be a frustrating and debilitating problem—making it difficult for you to think clearly, communicate effectively, and carry out everyday tasks. 

Brain fog can have a significant impact on your quality of life, especially since it can last from a few days to a few months and even longer.

It can be accompanied by other symptoms such as physical and mental fatigue, difficulty concentrating, and memory problems.

Other common symptoms include: 

  • headaches
  • anxiety
  • depression
  • irritability
  • mood swings
  • exhaustion
  • slow thinking
  • difficulty in decision-making
  • troubles with problem-solving
  • constantly losing trails of thought in conversations.

If you develop brain fog symptoms, we highly advise that you see a doctor that can rule out any underlying medical conditions that may be causing your brain fog.

Once any potential medical causes have been ruled out, there are a few different options for treating brain fog and other cognitive impairments.

What causes brain fog?

There are many possible causes of brain fog.

It can be a side effect of certain medications, such as antidepressants, anti-anxiety drugs, and sleeping pills.

Brain fog can also be caused by mental health conditions and medical conditions, such as:

  • depression
  • anxiety
  • bipolar disorder
  • ADHD
  • sleep disorders
  • multiple sclerosis
  • lupus (i.e., lupus brain fog)
  • cancer and chemotherapies (i.e., chemo brain)
  • chronic fatigue syndrome.

In most cases, you will experience brain fog because of a lack of sleep, poor nutrition, lack of physical activity or exercise, and stress, among many other factors.

What is the best medicine for brain fog?

The truth is, as of this writing, there is no approved drug for brain fog in the United States.

Although no medications are licensed in the US to cure brain fog, several medicines, types of psychotherapy, and at-home treatments may help to alleviate or manage it.

This is why the best remedy for brain fog will vary from person to person.

Some people may find relief with over-the-counter medications such as antihistamines or pain relievers.

Others may need to see a doctor for the right prescription medication, which we highly recommend.

There are also many natural remedies that can help you fight brain fog and possibly cure it for good, such as lifestyle changes, vitamins, and supplements.

You may want to consider taking the following:

Choline Bitartrate

This supplement is a water-soluble vitamin that helps with nerve function, muscle movement, immune system, and metabolism.

One study found that choline bitartrate can help improve cognitive performance and memory among older adults. It’s also necessary for the transportation of fats in the body.

You can find choline bitartrate in eggs, beef liver, soybeans, cauliflower, and peanuts. It can also be taken as a supplement in the form of capsules, tablets, or powders.

If you’re taking it as a supplement, it’s suggested that adult females take 425 mg daily and males take 550 mg daily to maintain proper nutrition.

Gamma Oryzanol

Gamma oryzanol is a natural compound found in rice bran oil.

It’s often used as a supplement to help with menopause symptoms, such as hot flashes and night sweats.

Research suggests that gamma oryzanol may also help improve cognitive function and alleviate brain fog by crossing the blood-brain barrier in intact form and exerting beneficial effects on brain cells.

You can get it from eating rice bran, or you can take it as a supplement in the form of capsules, tablets, or powders.

If you’re taking gamma oryzanol as a supplement, the recommended dosage is 200-400 mg per day.

Ginkgo Biloba Extract

Ginkgo biloba is a tree native to China that’s been used in traditional medicine for centuries.

The leaves of the ginkgo biloba tree are often used to make an extract that’s taken as a supplement.

Ginkgo biloba extract is believed to clear brain fog by improving blood circulation and brain health.

Studies suggest that it may be effective in treating Alzheimer’s disease and dementia.

You can find ginkgo biloba extract in capsules, tablets, or liquids. The suggested dosage is 120-240 mg per day.

L-Carnitine

L-carnitine is an amino acid that’s found in red meat and other animal-based products.

Your body needs L-carnitine to produce energy.

It’s also considered to help with brain function, heart health, and weight loss.

One study suggests that Acetyl-L-carnitine, a more absorbable type of L-Carnitine, can help improve brain functions in people with dementia and other mental disorders.

You can find L-carnitine in supplements, which are usually taken in the form of capsules, tablets, or powders.

The suggested dosage is 500-2000 mg per day if you’re taking an L-carnitine supplement.

L-Tartrate

L-tartrate is a type of L-carnitine that’s found in red meat, dairy products, and some vegetables.

Like L-carnitine, L-tartrate is assumed to help with energy production and cognitive function.

One study showed that taking L-tartrate with a balanced diet might help prevent Alzheimer’s disease. The supplement has also improved the reaction times and brain function of people taking it.

You can find L-tartrate in supplements, which are usually taken in the form of capsules, tablets, or powders.

If you’re taking an L-tartrate supplement, the suggested dosage is 500-2000 mg per day.

L-Theanine

L-theanine is an amino acid that’s found in tea leaves, especially green tea.

It’s expected to have several health benefits, including improved mental focus and stress relief.

One study showed that L-theanine could help improve memory and cognitive function in people with Alzheimer’s disease.

You can find abundant L-theanine in both green tea and black tea. It can also be taken as a supplement in the form of capsules, tablets, or powders.

If you’re taking an L-theanine supplement, the suggested dosage is 200-400 mg per day.

Magnesium

Magnesium is a mineral that’s found in green leafy vegetables, nuts, and seeds.

It’s necessary for hundreds of biochemical reactions in the body, and it’s considered to have several health benefits.

These include improved blood sugar control, reduced inflammation, and improved heart health.

Studies suggest that magnesium may help enhance memory and learning as well as aid symptoms of neurological disorders.

You can get magnesium from your diet or by taking supplements.

If you’re taking a magnesium supplement, the recommended daily allowance for adults is 310-420 mg.

Omega-3 Fatty Acids

Omega-three fatty acids are a type of polyunsaturated fat that’s found in certain fish, such as salmon, mackerel, and sardines.

They’re also found in flaxseeds, chia seeds, and walnuts.

Omega-3 fatty acids are believed to have several health benefits, including reduced inflammation, improved heart health, and enhanced brain functions.

One study showed that omega-three fatty acids could help improve memory and learning in people with Alzheimer’s disease.

You can get omega-three fatty acids from your diet or by taking supplements.

If you’re taking an omega-three supplement, the suggested dosage is 250-500 mg per day.

Phosphatidylserine

Phosphatidylserine is a type of phospholipid that’s found in the brain.

It’s necessary for the structure and function of nerve cells.

Phosphatidylserine is also involved in the production of neurotransmitters, which are chemicals that help communication between nerve cells.

Studies suggest that phosphatidylserine may help improve brain function, memory, learning, and retention of cognitive functioning ability even as an individual ages.

It’s also been shown to aid symptoms of Alzheimer’s disease and dementia.

You can find phosphatidylserine in supplements, which are usually taken in the form of capsules, tablets, or powders.

If you’re taking a phosphatidylserine supplement, the suggested dosage is 200-400 mg per day.

Soy Lecithin

Soy lecithin is a type of phospholipid that’s derived from soybeans. It’s found in many processed foods as an emulsifier.

Soy lecithin is also available as a supplement, and it’s assumed to have several health benefits, including improved heart health and enhanced mental clarity.

One study showed that soy lecithin could help improve memory, mood, cognition, daily functioning, and learning in people with Alzheimer’s disease.

You can find soy lecithin in supplements, which are usually taken in the form of capsules, tablets, or powders.

If you’re taking a soy lecithin supplement, the suggested dosage is 1200-2400 mg per day for adults.

Vitamin A Acetate

It can also be found in some plant foods, such as sweet potatoes, carrots, and spinach.

Vitamin A is important for vision, immune system function, and reproduction.

Studies suggest that vitamin A may help improve brain function, learning, and behavior as well as prevent symptoms of Alzheimer’s disease.

You can get vitamin A from your diet or by taking supplements.

If you’re taking a vitamin A supplement, the recommended daily allowance for adults is 900 micrograms (mcg) for men and 700 mcg for women.

Vitamin B Complex

Vitamin B complex is a group of eight water-soluble vitamins that play essential roles in cell metabolism. It includes:

  • thiamine (B₁)
  • riboflavin (B₂)
  • niacin (B₃)
  • pantothenic acid (B₅)
  • pyridoxine (B₆)
  • biotin (B₇)
  • folic acid (B₉)
  • cobalamin (B₁₂)

Vitamin B complex is involved in many processes in the body, including energy production, red blood cell formation, and nervous system function.

Studies suggest that the vitamin B complex may help improve brain function, and vitamin B12 is specifically helpful in aiding symptoms of brain fog.

These vitamins are found in a variety of foods, such as meat, poultry, fish, eggs, milk, and some fortified cereals and bread.

If you’re taking a vitamin B supplement, the suggested dosage is 25-100 mg daily.
