Brain fog symptoms: can mineral deficiencies play a role?
Do your thoughts keep drifting away and does your head constantly feel foggy? You might be missing more than just focus; you could be lacking essential minerals.

Brain fog. A term that is popping up more and more. Being unable to focus. Thoughts that slip away. Reading a paragraph three times. Forgetting what you were just about to say. Fatigue that is present in the morning, even before you have done anything. Shortness of breath when climbing stairs. Stamina that is slowly but surely getting worse. Headaches that are just part of the deal. Restless legs in the evening. Dizziness when standing up quickly.
Brain fog symptoms can significantly disrupt your daily life. Could these brain fog symptoms be caused by a mineral deficiency? It is possible, but the connection is more complex than is often suggested.
A deficiency can affect the functioning of the body and the brain.
Brain fog is not an official medical diagnosis. It is an umbrella term for complaints related to thinking, attention, memory, and mental energy. Brain fog does not have a single cause, but according to experts, you can take certain steps to combat the symptoms by looking at your lifestyle.
Common brain fog symptoms include:
Not everyone experiences the same symptoms. For some, forgetfulness is the main issue, while others primarily struggle with mental slowness or difficulty reading and speaking. Furthermore, the severity can fluctuate from day to day or even hour to hour. If
Brain fog is often described as thinking through a thick haze. You are awake, but you don't feel sharp. Information comes in, but it doesn't seem to be processed or stored properly. You walk into a room and forget why you went there. You lose your train of thought during a conversation. You open an email and forget what it said after the first few lines. A task that used to be second nature suddenly requires a step-by-step approach. This can cause feelings of insecurity.
People sometimes worry that their memory is severely declining, while the problem may actually stem from temporary disruptions in attention, information processing, and mental energy.
Brain fog symptoms can occur alongside other physical complaints, such as:
Hair loss, brittle nails, and pale skin are not direct symptoms of brain fog. However, when these occur alongside fatigue and concentration problems, they may point to an underlying issue, such as an iron deficiency.
Minerals are essential for nerve cell function, energy production, oxygen supply, and the immune system. Our bodies cannot produce these substances themselves. We must obtain them every day through food and drinking water.
And that is exactly where the problem lies. Our modern diet does not always provide sufficient minerals. Many people have a limited diet, consume many highly processed products, and do not get enough mineral-rich foods.
In addition, soil conditions, cultivation, processing, and preparation can affect mineral content.
Blood loss, increased requirements, or poor absorption in the gut can also cause a deficiency.
A demonstrable deficiency can contribute to fatigue, weakness, and cognitive complaints.
The link is usually indirect:
insufficient intake, increased loss, or poor absorption → mineral deficiency → impaired bodily functions → fatigue and cognitive complaints
However, brain fog alone does not prove that someone has a deficiency. These symptoms can also occur with sleep deprivation, stress, hormonal changes, medication use, and various physical conditions.
Of all minerals, iron has the clearest relationship with a combination of fatigue and concentration problems. The body needs iron to produce hemoglobin. This protein in red blood cells transports oxygen to the tissues. Long-term iron deficiency can lead to anemia. As a result, the body is less efficient at transporting oxygen.
Possible symptoms of iron deficiency or anemia include:
Low iron stores without clear anemia can also sometimes be associated with symptoms. The relationship is less straightforward in such cases. Whether a deficiency truly exists can only be determined through blood tests.

Magnesium is essential for hundreds of processes in the body. It helps convert nutrients into energy, supports nerve impulse transmission, and is involved in the functioning of muscles, the brain, and the immune system. Magnesium also plays a role in regulating inflammatory responses and protecting cells against oxidative stress.
A deficiency can manifest as fatigue, muscle weakness, cramps, irritability, and difficulty concentrating.
The risk of a deficiency increases with an unbalanced diet, chronic intestinal issues, frequent alcohol consumption, and the use of certain medications, including some antacids and diuretics. Persistent diarrhea and poorly managed diabetes can also lead to additional magnesium loss.
However, like other minerals, magnesium does not function in isolation. It works closely with calcium, potassium, sodium, and phosphate, among others. Vitamin D is also important for maintaining this balance. Consequently, a disruption in one mineral can affect the absorption, excretion, or function of others.
That is why simply taking a magnesium supplement is not always the best approach.
A single supplement does not resolve an unbalanced diet, poor absorption, or a broader disruption of the mineral balance. The foundation remains, of course, a varied diet including green leafy vegetables, nuts, seeds, legumes, and whole-grain products.
Iodine is necessary for the production of thyroid hormones. These hormones influence metabolism, energy, and brain function, among other things.
A long-term iodine deficiency can contribute to an underactive thyroid. Possible symptoms include:
An underactive thyroid can have various causes. I know from personal experience how much of an impact that can have. Years ago, I was diagnosed with an underactive thyroid myself. The expectation was that I would have to take medication for the rest of my life. I didn't just accept that prospect.
I decided to thoroughly adjust my diet and started using SMPL72. I haven't had any thyroid issues since. That was years ago now.
My experience is not scientific proof that SMPL72 treats a thyroid condition or can replace medication. I want to be clear about that. But it is my personal experience, and that is why I feel it is worth sharing.
Zinc, selenium, and copper are trace elements: the body only needs small amounts of them. They support enzymes, nerve cells, and the immune system.
A severe deficiency can affect the immune system and the nervous system. However, these deficiencies are not a common explanation for everyday brain fog. Also, more is not automatically better.
Too much zinc, for example, can block the absorption of copper. This can lead to a copper deficiency, potentially causing anemia and neurological symptoms. An excess of selenium can actually cause hair loss, brittle nails, and nerve problems. Symptoms that resemble a deficiency can therefore sometimes also be caused by an excess.
Scientists are investigating whether deficiencies in certain minerals can contribute to neuroinflammation. This is an immune response in the brain and the rest of the nervous system.
In the brain, such a response is partly controlled by microglia. These are specialized immune cells that react to infections, damage, and other threats. Temporary activation helps protect and repair the brain. When microglia remain active for too long or too intensely, inflammatory substances may disrupt communication between nerve cells.
A possible process is:
mineral deficiency → increased oxidative stress → immune cell dysregulation → microglia activation → disruption of nerve cell communication
Magnesium and zinc, in particular, are being studied in this context. Animal and laboratory research suggests that a magnesium deficiency can activate inflammatory pathways and microglia. A disrupted zinc balance can also affect the regulation of inflammatory responses.
While this provides a biologically plausible explanation, it is not yet hard evidence that mineral deficiencies in humans are a common cause of brain fog via neuro-inflammation. Many findings come from cell and animal studies and cannot be directly translated to patients with brain fog.
A mineral deficiency does not need to cause brain inflammation to result in cognitive symptoms.
With an iron deficiency, for example, anemia can affect oxygen supply. With an iodine deficiency, cognitive symptoms can arise due to insufficient thyroid hormones. A severe magnesium deficiency can disrupt the normal functioning of nerve and muscle cells.
It is therefore too simplistic to categorize all brain fog caused by deficiencies under the umbrella of neuro-inflammation. Sometimes there is a more direct explanation. In other cases, it is not yet clear which mechanism is responsible.
A deficiency does not always occur because someone is not eating enough of a mineral. Sometimes the body is unable to properly absorb nutrients.
Reduced absorption can occur with, among other things:
Other factors also play a role. Blood loss due to heavy menstruation or gastrointestinal bleeding, for example, can cause an iron deficiency.
Foods can also influence each other's absorption. Coffee and tea reduce iron absorption when consumed around an iron-rich meal. Vitamin C, on the other hand, promotes the absorption of plant-based iron.
Mineral deficiencies are just one possible explanation. Brain fog can also be associated with:
Vitamin B12 and folate are not minerals, but deficiencies can cause anemia, fatigue, and neurological or cognitive issues.
There is often not just one single cause. Poor sleep, pain, stress, and physical fatigue can reinforce one another, making it increasingly difficult to concentrate and remember things.
When dealing with brain fog, people often reach for a single magnesium, iron, or zinc supplement. But taking just one mineral in a high dosage is a shot in the dark. Minerals work together and influence each other's absorption and function. For example, too much zinc can cause a copper deficiency, while an excess of iron, iodine, or selenium can also be harmful.
SMPL72 does not consist of one isolated mineral, but is a 100% natural mineral source in which various minerals occur together. It is linked to fulvic acid, the transport agent that ensures the minerals reach the cell.
Straight from nature. This supports the mineral balance through a broad composition, rather than with one randomly high-dosed mineral.
Between swallowing minerals and their utilization by your cells lies a complex biological process. A mineral on a label is not yet a mineral in a cell. First, it must be released from its food matrix or compound during digestion. The acidity of the stomach, digestive enzymes, and the chemical form of the mineral then determine how well it remains soluble. Only in a suitable, soluble form can the mineral reach the intestinal wall and be absorbed there via specific transport proteins or ion channels.
That absorption is strictly regulated. Intestinal cells do not let minerals through indiscriminately, but respond to the body's needs, existing stores, and the presence of other substances.
Minerals can work together, but they can also compete with one another.
High doses of zinc, for example, can disrupt copper balance.
Calcium, magnesium, iron, and other minerals can also utilize overlapping absorption processes or influence each other's availability.
A large amount of a single isolated mineral therefore does not guarantee better absorption and can actually disrupt the internal balance.
After passing through the intestinal wall, the next phase begins. Minerals are transported via the blood, often bound to transport proteins, and must then reach the correct tissue. Subsequently, they must enter the cell, arrive at the right location, and be available for enzymes and other cellular processes. Magnesium, for example, is required for reactions that use ATP: the cell's energy carrier functions largely as a magnesium-ATP complex. Iron is essential for hemoglobin, but also for enzymes in the mitochondria involved in energy production. Zinc supports hundreds of enzymes and regulatory processes, while selenium is a component of enzymes that help protect cells against oxidative damage.
Balance remains important within the cell as well.
Minerals do not function as isolated components, but as cofactors within complex networks of enzymes, electrical gradients, and signaling pathways. The cell must constantly maintain the correct concentrations. Too little can slow down processes, but too much can be just as disruptive or even toxic. The body therefore possesses transporters, storage proteins, and excretion mechanisms to precisely regulate mineral balance.
That is the philosophy behind SMPL72: not simply stacking more and more individual substances.
SMPL72 contains fulvic acid, which is naturally bound to a broad spectrum of minerals and trace elements. Naturally means that nothing has been added in a factory.
Due to its chemical properties, fulvic acid can form bonds with mineral ions and influence their solubility. How much of that is ultimately absorbed and utilized in cells remains dependent on factors such as dosage, gut function, individual needs, and overall diet.
The core concept is simple, yet biologically fundamental: what you ingest is not automatically what you absorb, and what you absorb is not automatically what your cells can use. The true value of minerals only emerges when they are soluble, pass the intestinal barrier, reach the correct tissue, and become available there for the processes for which the body needs them.

Read: what is fulvic acid, how it works, what it does, and why you need it.
Everything you want to know about SMPL72, enrollment, and how it works. Still have questions? We've got the answers.
This varies from person to person and depends primarily on your starting point. Fulvic acid supports the absorption and bioavailability of the minerals you already get through your diet or supplements. The faster your body responds to that improved availability, the sooner you will notice a difference. People with low mineral levels or higher requirements often experience changes sooner than those who are already well-nourished. Some users notice more clarity or a calmer energy level within a few days, while for others, it happens more gradually over a period of weeks. In SMPL72, the fulvic acid is naturally bound to 72 different minerals and trace elements. The most important thing is consistency: fulvic acid doesn't act as a quick stimulant, but as a daily absorption mechanism that builds its effect step by step.
People often get some minerals from various sources, but usually not enough. Furthermore, they are often poorly absorbed by the digestive system. It is important to realize that most supplements are synthetic, and in the case of minerals, they are essentially just rock. These contain large molecules that your body can barely absorb, if at all. We have previously written a blog post about the ins and outs of supplementation; feel free to check out our blog section. You might already be taking magnesium or zinc, but keep in mind that you are only taking one or two of the 60 minerals your body needs every day. When you think in terms of a complementary approach, you cannot simply pick one mineral out of the entire spectrum.
Fulvic acid is not an energy booster, nor is it a substance that provides an immediate effect on fatigue or concentration. What it does is something more fundamental: it supports the way your body absorbs and utilizes minerals. And that very point—the utilization of minerals—plays a bigger role for many people than they realize. Fatigue, "brain fog," and concentration issues often have multiple causes, but in orthomolecular practice, it is frequently observed that mineral metabolism and electrolyte balance are significant factors. Minerals are necessary for processes such as: - signal transmission in the nervous system - energy production in the mitochondria - oxygen transport - fluid balance in and around the cell - enzyme activity involved in focus, alertness, and metabolism If those minerals are insufficiently available at the cellular level, the body cannot perform these processes efficiently. Fulvic acid cannot solve that on its own, but it makes minerals chemically smaller, more soluble, and more accessible to the body. As a result, the minerals you ingest through food or supplements can be better utilized where they are needed. Many users experience a more stable energy level, greater clarity, or fewer fluctuations throughout the day. Not because fulvic acid provides a direct stimulant, but because minerals are able to do their job better. This is a fundamentally different mechanism than that of caffeine, stimulants, or "energy boosters." It remains important to emphasize: fulvic acid is not a treatment for fatigue or concentration issues. It merely supports the biological foundation upon which energy, clarity, and nerve function operate. What an individual notices from it naturally also depends on diet, hydration, lifestyle, and individual needs.
Fulvic acid has a very mild, almost neutral taste. Most people barely notice it when they add a few drops to a glass of water. Some describe it as having a very light mineral flavor, but you usually only notice it if you are really paying attention. SMPL72 is pure fulvic acid with no additives, which keeps the taste soft, clean, and subtle. You don't need to worry about a bitter, sharp, or "muddy" taste, which is common in impure or thick humic products.Most users find that it simply tastes like water with a very faint hint of minerality. This makes it easy to use every day, even for children or people who are sensitive to strong flavors. It is best to take SMPL fulvic acid in a glass of chlorine-free water. Fruit juice is also an option, but avoid hot drinks. It is very easy to use.
Add 7-10 drops daily to a glass of (chlorine-free) water (fruit juice is also an option, but avoid hot drinks). For children: 1 drop per 10 kg of body weight. Feel free to increase the dose during illness or intense physical exertion. For maximum absorption: take 30 minutes before a meal. For an energetic start to the day: take in the morning on an empty stomach. For recovery: take immediately after sports or physical exertion. SMPL72 is a powerful detox, so be sure to drink plenty of water. If you are pregnant or taking medication, build up the dose gradually and monitor how your body reacts. When in doubt, consult your doctor or midwife.
