What is Brain Fog?

What is Brain Fog

We’ve all had those moments:

scouring the house for lost keys that somehow appear in our pocket, struggling to sputter that neighbor’s name on the tip of our tongue, and circling the parking lot while clicking the alarm button until we see the lights flash on our car.

If left unaddressed, these minor episodes can switch from occasional annoyances into a debilitating set of symptoms called brain fog. Brain fog is a general term for dysfunctions in focus, learning, and memory that can create brief episodes of confusion, disorientation and frustration.  Brain fog is a source of anxiety for many older patients.

We understand how distressing such disorientation can be. That’s why we’ve spent years sourcing, synthesizing, and clinically validating Cerenx®, a brain fog-alleviating medical food product that is now available to help.

Recent studies have shown that Cerenx® can help treat the symptoms and causes of brain fog and potentially protect brain cells from further damage. To learn more and discover how Cerenx® can improve your mental health, call (800) 971-3721 (ext 3) or contact us here

What does brain fog feel like?

Brain fog patients often report a nagging fatigue, irritability, anxiety, depression, headaches, and/or insomnia. This cognitive state can also make it difficult for you to:

– Remember and understand information or spoken language

– Organize your thoughts

– Problem-solve in common or routine situations

– Focus on the task at hand or in conversation

– Plan your day or for a task ahead

– Draw or recognize common shapes

– If brain fog is not addressed and controlled, your condition can intensify and eventually profoundly impact your professional, social, and personal life.

Why do I feel foggy?

Middle age is a major culprit of brain fog, as it induces drastic hormonal changes which science calls menopause in women and andropause in men.

The American Congress of Obstetricians and Gynecologists estimates that over 2 million women reach menopause every year1, as their estrogen levels begin to naturally decline drastically for some. About 25 million American men are also experiencing andropause2, the gradual decline of testosterone levels.

These gender-based hormones help regulate the stress hormone cortisol, which affects neurotransmitters in the brain and can cause our blood circulation and energy metabolism to slow down. 

The phospholipids in our brain cells mediate the activity of those neurotransmitters and hormones, as well as form membrane barriers that protect us from charged particles.  Phospholipids are important in a variety of brain cell functions. When these phospholipids begin to degrade, so does our brain’s information processing ability.

Besides hormonal imbalances, brain fog dysfunctions can be stimulated by:

– Leaky gut syndrome, which causes brain inflammation3

– Fibromyalgia and chronic fatigue syndrome4

– Stress, depression and anxiety which affects brain function5

– Anemia, which can cause a lack of oxygen in your body6

– Thyroid dysfunctions like hypothyroidism7

– Diabetes, which can impair glucose, your brain’s primary energy source8

– Magnesium, vitamin B12, amino acid deficiency or dehydration (brain malnourishment)9

– Brain inflammation from multiple sclerosis (MS)10

– Memory and concentration dysfunctions can also be side effects of common medications
like chemotherapy drugs, antidepressants, and sleep aids.

How can Cerenx® relieve your brain fog?

Recent clinical studies included a trial performed by MIT have demonstrated that the medical food Cerenx® improved:

– Focus in healthy women14

– Improved motor function in adolescent males15

– Improved verbal memory in aging adults12


Citicoline stimulates the production of membrane phospholipids in brain cells, while simultaneously reducing the degradation of those phospholipids. The more phospholipids our brain can produce, the more effectively our brain can function and mediate our hormone and neurotransmitters.

Multiple clinical studies at Harvard Medical School and McLean Hospital suggest Citicoline also has a triple effect on dopamine in the brain:

– Increasing dopamine levels 16,17

– Increasing density of dopamine receptors 16,17

– Protecting dopamine-related neurons 13
