We all feel overwhelmed at times in a world of endless diversions and severe anxieties. We all have days when we are perplexed, find it difficult to focus on our work, or make a series of errors that negatively affect our productivity and performance. Brain fog can strike at the most inconvenient times, so how can you clear it up quickly? One way to combat brain fog is with vitamins and nutrients. Let’s take a look at your top options.

The top 10 vitamins for clearing brain fog

What is brain fog?

The phrase “brain fog” refers to a set of symptoms that include deteriorating memory, inability to focus, difficulties processing information, weariness, and jumbled thinking. It is not a medical phrase, but rather a term used in a broad meaning.

Brain fog caused by stress or worry usually clears up on its own after a while. However, if it becomes a frequent occurrence and begins to interfere with your everyday activities, it may have a significant underlying condition. Brain fog can be caused by underlying illnesses such as Hashimoto’s thyroiditis, chronic fatigue syndrome, depression, autistic spectrum disorder, celiac disease, and neuropsychiatric problems, all of which may necessitate medical attention.

Can Vitamins Help You With Brain Fog?

Yes! Certain vitamins and key nutrients can help you to cope with brain fog. Let’s take a closer look.

1. Vitamin D – Cognitive Focus

Vitamin D is a fat-soluble chemical that is needed for the health of the brain, the operation of the immune system, and a variety of other body activities.

Vitamin D deficiency can have a detrimental influence on cognitive function and contribute to the symptoms of brain fog. People who have depression or depressive symptoms frequently

experience brain fog indicators such as poor focus and memory problems. Deficits in various vitamins, including vitamin D, are more common in those who suffer from depression.

Deficiency in vitamin D has been linked to an increased incidence of depressive symptoms. Vitamin D pills, according to research, can help boost vitamin D levels and alleviate depression symptoms including cognitive fog (1, 2, 3, 4, 5).

2. B-Complex Vitamins – The Memory Boosters

Memory issues, trouble concentrating, and other symptoms of brain fog can be caused by low or insufficient levels of particular B vitamins.

B12 supplementation enhanced cognition in 84 percent of participants and improved memory and attention scores in 78 percent of participants, according to a study of 202 persons with cognitive impairment and low or insufficient B12 levels.


3. Magnesium – The Energy Generator

Magnesium is a trace element that may be found in a variety of foods, including seeds, spinach, and beans.

Many vital physiological activities rely on it, including enzyme reactions, energy generation, neuron activity, and blood pressure management. Some studies found a relationship between low magnesium levels and worse cognitive function and response speed, as well as an increased chance of developing cognitive impairment in the future.

A study of 2,466 persons aged 60 and older revealed that those with greater magnesium levels performed better on tests of cognitive skills such as attention and memory and had a reduced risk of cognitive impairment than those with lower magnesium levels.

4. L-theanine – Mental Clarity

Green tea and other plants contain a substance known as L-theanine, which is beneficial to the body.

Consuming an L-theanine supplement can help you increase your mental acuity, response quickness, and memory.

A recent study showed that a single injection of 100.6 mg of L-theanine enhanced response time and cognitive ability on tests in 69 people aged 50–69.

5. Vitamin C – The Immune Booster

Vitamin C is well-known for its role in immune health, but it also helps with a variety of other bodily processes, including brain health.

A study of 80 healthy people revealed that those with appropriate vitamin C levels in their blood scored much better on memory, attention, response time, and concentration tests than those with low vitamin C levels.

6. Omega-3 Fatty Acids – Healthy Heart

In addition to their health-promoting properties, omega-3 fatty acids are well-known for their ability to reduce inflammation in the body.

It can also prevent the buildup of plaque in your arteries, which can lead to high cholesterol and heart disease.

Taking concentrated omega-3 supplements may enhance brain health and alleviate certain symptoms of brain fog, such as difficulty paying attention and remembering things. 

In a trial of 176 people with poor omega-3 consumption, supplementing with 1.16 grams of DHA per day for six months improved episodic and working memory when compared to a placebo group.

7. Vitamin E – Stress-Free

Taken in appropriate amounts, Vitamin E can improve brain health by lowering oxidative stress levels in the body.

Some types of vitamin E, such as DL-Alpha-Tocopherol Acetate, operate as antioxidants, reducing free radical damage and aiding in the battle against inflammation. Nuts and seeds, wheat gram, and plant-based oils are all good sources of vitamin E to consume in adequate quantities. Additionally, nutritional supplements might be a fantastic alternative.

It is possible to overdose on vitamin E, so it’s important to speak to your doctor about this option.

8. Soy lecithin – Liver Repairman

Lecithin is a kind of lipid that may be found in the cells of the body.

It has been shown to improve memory and the capacity to acquire new abilities, which can help to enhance brain function.

It also has additional benefits for moisturizing the skin and helping nursing moms prevent clogging in milk ducts.

Soy lecithin can also help prevent the buildup of fat in the liver, and protect it from alcohol and damage, which helps to improve liver function.

9. Phosphatidylserine – Mood Booster

Because it includes amino acids and fatty acids, phosphatidylserine is beneficial in the treatment of mental fatigue. It’s a natural substance in our bodies that has been shown to reduce cortisol levels, which is the hormone associated with stress.

By regulating cortisol levels, phosphatidylserine can help promote a feeling of calmness and relaxation, leading to an overall improvement in mood. And if you’re an athlete, you might be interested to know that phosphatidylserine can help enhance athletic performance by improving endurance and decreasing muscle damage.

10. Ginseng Extract – Healthy Energy Drink

Ginseng extract works by controlling the impact of stress on the immune cells. Ginseng root has been used for centuries in traditional medicine. 

It has the potential to boost mental capacities such as memory and mood, while also providing additional health advantages such as inflammation reduction. This little plant packs a powerful punch when it comes to giving you energy without the crash. 

Ginseng extract helps boost mental and physical performance, reduce fatigue, and even improve mood. It’s like a little energy-boosting ninja, ready to take on any challenge.


IV treatments for clearing brain fog

In addition to the vitamins above, NAD + IV therapy can help clear brain fog. NAD+ is essential for cellular health, especially mitochondrial activity, which is necessary for metabolism and general health. Our NAD+ supply depletes as we become older. Supplementing with NAD+ can help to counteract these negative effects.

NAD aids in the proper functioning of the brain. By increasing sirtuins, a protein that acts as an anti-aging mechanism, this coenzyme rejuvenates and restores brain function, slowing the impacts of neurodegenerative illnesses and normal cognitive decline. Those who have used NAD+ supplements may experience improved memory, attention, and vitality, all of which can help alleviate symptoms of brain fog.

NAD - Frequently Asked Questions

What is NAD?

NAD is a coenzyme that is naturally produced by the body and is essential for various physiological processes, including energy production and DNA repair. It is found in all living cells and plays a critical role in many of the body's metabolic processes. NAD is a dinucleotide, which means that it consists of two nucleotides joined together. It is made up of two molecules: nicotinamide and adenine, which are joined together by a phosphate group.

NAD is involved in a wide range of biological processes, including the metabolism of carbohydrates, proteins, and fats, and is essential for the proper functioning of the body's cells and tissues.

What can I expect during a NAD IV treatment?

Our nurse will arrive at your location of choice with all the equipment necessary for the appointment. They will then administer the IV into your arm and stay with you to monitor the treatment and answer any questions you may have.

Our NAD IV treatments generally last couple of hours per session. You can sit back, watch a movie or a favorite show, browse social media, or even work while the treatment is in progress.

What sets Drip Hydration apart from other NAD IV treatment providers?

Drip Hydration brings appointments directly to you whether you are at home, at a hotel, or at the office. We make getting at home NAD IV treatments easy and convenient, saving you the time and hassle of sitting in traffic or waiting in a clinic.

Is NAD right for me?

You don’t have to wait until you are experiencing a medical condition to enjoy the benefits of NAD IV therapy. NAD plays a role in hundreds of chemical functions throughout your body. This versatile treatment helps promote whole-body wellness and can help your body maintain optimal performance over time.

Is IV therapy FDA approved?

IV therapy in general is FDA approved. Our nurses are overseen by our Medical Director, Abe Malkin, and every nurse is registered and certified per state standards.

Is NAD safe?

NAD is considered a dietary supplement, not a drug. The FDA does not currently evaluate dietary supplements in their current regulations. However, NAD is well-tolerated, meaning that there are rarely side effects.

How long do IV treatments take?

Our IV NAD treatments take couple of hours to administer per session. The number of sessions vary by individual and will be determined during your initial consultation.

Does NAD help battle aging?

Some studies have suggested that NAD may have anti-aging effects by helping to support the production of enzymes that are involved in DNA repair and maintenance, which are essential for maintaining healthy cells and tissues. Additionally, NAD may support the production of enzymes that are involved in the body's natural detoxification processes, which can help to reduce the effects of oxidative stress and support healthy aging. 

Does NAD Improve metabolic function?

Some studies have suggested that NAD may support healthy metabolism by helping to regulate the body's energy production and utilization, and may also support the production of enzymes that are involved in various metabolic processes. Additionally, NAD may support the body's natural detoxification processes, which are important for maintaining overall health and wellness.

How often can I get an NAD treatment?

NAD IV treatments are most effective when used over time. You can get treatments several times per month unless you are otherwise advised during your initial consultation.

What can I expect to feel after a NAD IV drip?

Following a NAD IV drip, most patients feel more energetic, clearer-headed, and focused. Regular treatments may improve these effects over time.

Is there any downtime or recovery after a NAD drip?

Not at all! You can resume your normal activities immediately after your appointment. Where do you deliver NAD IV treatments? Drip Hydration delivers NAD IV treatments anywhere within our service areas, which you can find on our service area pages. That said, we recommend choosing a comfortable place for NAD treatments since this type of IV takes couple of hours per appointment.

How is IV NAD better than an oral NAD supplement?

IV NAD is delivered directly into your bloodstream, where it becomes available to your cells for immediate use. Because NAD bypasses the digestive and metabolic systems, you can expect a 100% absorption rate for maximum effect and minimal waste. Oral NAD supplements, on the other hand, must pass through your digestive system, where they are partly metabolized before your body has access to orally given NAD.

What is the difference between a NAD IV and a vitamin drip?

There are two main differences between a NAD IV and a Vitamin Drip: duration and ingredients. NAD IVs generally take couple of hours to administer per session while vitamin drips take 30 - 45 minutes. Our vitamin drips are specially blended to improve a variety of symptoms and ailments. Our NAD+ Boost treatments contains vitamins that can help make this IV more effective with longer-lasting effects.

Do I need any special supplies for my NAD IV appointment?

No, you do not need any special supplies. Our nurse will bring everything needed for the appointment.

Does NAD improve brain health and function?

NAD is believed to have potential benefits for brain health and function, although more research is needed to fully understand its effects. Some studies have suggested that NAD may have neuroprotective effects, meaning that it may help to protect the brain from damage and support healthy brain function. Additionally, NAD may support the production of neurotransmitters, which are chemicals that help to transmit signals between the brain's cells, and may help to improve cognitive function and memory.
