December 10, 2025Does your brain feel sluggish?
Are you struggling to focus, remember names, or connect your thoughts?
That “cloudy” feeling isn’t just aging or a bad night’s sleep.
It’s often a result of slow neural communication and chronic inflammation in your brain.
To truly eliminate that fog, you must target the root causes by lowering inflammation, boosting key neurotransmitters, and flooding your brain with oxygen.
We’ve compiled the 10 most powerful supplements shown in human trials to clear brain fog and restore cognitive function.

1. Omega-3 Fatty Acids (DHA)
This essential fat is the architectural building block of your brain, as 60% of the brain is composed of fat.
DHA specifically maintains the fluidity of cell membranes, allowing neurotransmitters to signal quickly and efficiently.
A deficiency leads to rigid cell membranes and slower processing speeds, manifesting as brain fog and forgetfulness.
In a study of 485 older adults with age‑related cognitive decline, daily supplementation with 900 mg DHA for 24 weeks significantly reduced learning errors and improved verbal recognition memory compared to placebo.
The doses of combined EPA and DHA used in trials addressing brain fog and cognitive performance are typically 1,000 to 2,000 mg per day, with a high concentration of DHA.
2. Curcumin
Curcumin is the main active ingredient in turmeric, best known for its strong anti‑inflammatory effects.
Because ongoing low‑level inflammation in the body can contribute to brain fog and even low mood, curcumin helps by entering the brain and calming these inflammatory signals.
However, regular curcumin does not absorb well in the body, so special formulations such as those combined with fats or other enhancers are needed to get noticeable benefits for memory and focus.
In a study of 60 healthy older adults, daily supplementation with 400 mg of lipidated curcumin for 4 weeks significantly improved working memory and mood compared to placebo, with additional acute benefits on attention observed within hours of dosing.
The doses of Curcumin used in clinical trials addressing brain fog and cognitive performance are typically 400 to 1,000 mg per day.
3. Bacopa Monnieri
Bacopa monnieri is a traditional Ayurvedic herb often described as a natural brain booster.
It helps nerve cells grow new branches, called dendrites, which strengthen the connections your brain uses to process and store information.
By improving how signals travel between brain cells and protecting them from damage caused by oxidative stress, Bacopa supports sharper memory and quicker thinking.
People who feel their mental speed has slowed with age often find it especially helpful.
In a study of 46 healthy adults, daily supplementation with 300 mg Bacopa monnieri for 12 weeks significantly improved the speed of visual information processing, learning rate, memory consolidation, and reduced state anxiety compared to placebo.
The doses of Bacopa monnieri used in clinical trials addressing brain fog and cognitive performance are typically 300 to 450 mg per day of a standardized extract, taken for at least 12 weeks.
4. L-Theanine
L‑Theanine is a natural amino acid found in green tea that helps create a calm but alert state of mind.
It works by boosting alpha brain waves, which are linked to “wakeful relaxation” and better focus, while also balancing the brain’s excitatory signals so you don’t feel overstimulated.
This is why L‑Theanine is often used to smooth out the jittery, anxious feeling that can come from stress or too much caffeine, leaving you clear‑headed and focused without drowsiness.
In a study of healthy young adults, a single dose of 97 mg L‑Theanine combined with 40 mg caffeine significantly improved accuracy during task switching compared to placebo.
The doses of L‑Theanine used in clinical trials addressing brain fog are typically 200 to 400 mg per day, often taken as a single dose or divided across the day.
5. Citicoline
This compound helps your brain make acetylcholine, a key neurotransmitter that powers learning, memory, and even muscle movement.
It also boosts the brain’s energy use and helps keep the protective membranes around your nerve cells strong.
When acetylcholine levels drop, people often notice “tip‑of‑the‑tongue” word‑finding problems and a general loss of mental sharpness.
In a study of 40 healthy adults, daily supplementation with 500 mg of citicoline for 2 weeks significantly improved vigilance and visual working memory compared to placebo, while also reducing oxidative stress markers.
The doses of Citicoline used in clinical trials addressing brain fog are typically 250 to 500 mg per day.
6. Lion’s Mane Mushroom
Lion’s Mane is a medicinal mushroom known for helping the brain grow and repair itself.
It stimulates the production of Nerve Growth Factor (NGF), a protein that supports the survival and regeneration of neurons, the cells that carry messages in your brain.
By strengthening these neural connections, Lion’s Mane may help clear away brain fog and support sharper, more focused thinking.
In a study of adults, daily supplementation with Lion’s Mane mushroom for 12 weeks significantly improved cognitive function scores on the Mini Mental State Examination compared to placebo and helped prevent cognitive decline.
The doses of Lion’s Mane mushroom extract used in clinical trials addressing brain fog and cognitive performance are typically 500 to 3,000 mg per day.
7. Phosphatidylserine
Phosphatidylserine is a natural fat-like substance that protects your brain cells and helps them send signals to each other.
It’s important for keeping memory sharp and mood balanced because it helps control cortisol, the stress hormone.
When levels of phosphatidylserine are low, people may notice trouble concentrating and more frequent memory lapses.
In a study of 149 older adults with age‑associated memory impairment, daily supplementation with 300 mg phosphatidylserine for 12 weeks significantly improved learning and memory performance compared to placebo, with the greatest benefits seen in those with lower baseline scores.
The doses of Phosphatidylserine used in clinical trials addressing brain fog are typically 100 to 300 mg per day,
8. Ginkgo Biloba
Ginkgo Biloba is one of the oldest living tree species and has been used for centuries to support circulation.
It helps widen blood vessels and makes blood less sticky, which improves the flow of oxygen and glucose to the brain.
By boosting blood supply, Ginkgo also helps clear away waste products that can build up and contribute to that heavy, foggy feeling in the head, leaving you with sharper mental clarity.
In a study of 20 healthy young adults, a single dose of 240 mg or 360 mg Ginkgo biloba significantly improved speed of attention during demanding cognitive tasks compared to placebo, with effects lasting up to 6 hours.
The doses of Ginkgo Biloba extract used in clinical trials addressing brain fog are typically 120 to 240 mg per day.
9. Acetyl-L-Carnitine
Acetyl‑L‑Carnitine is a special amino acid that can cross into the brain and give energy to its “power plants,” the mitochondria.
By boosting this energy supply, it helps protect brain cells and supports clear thinking.
ALCAR is especially useful for fighting the mental fatigue that comes with aging or long‑term stress, helping you stay alert and mentally resilient throughout the day.
In a study of patients with mild cognitive impairment or early Alzheimer’s disease, daily supplementation with 1.5 to 3.0 g of Acetyl‑L‑Carnitine for 3 to 12 months significantly improved memory and overall cognitive function compared to placebo.
The doses of Acetyl‑L‑Carnitine used in clinical trials addressing brain fog and cognitive performance are typically 1,500 to 3,000 mg per day, often taken in divided doses.
10. L-Tyrosine
L-Tyrosine is an amino acid that your body uses to make dopamine and norepinephrine, two key brain chemicals that drive motivation, focus, and mental sharpness under pressure.
Instead of simply stimulating the brain, L Tyrosine helps refill the mental resources that get drained during stress or heavy multitasking. This makes it especially useful for stress related brain fog.
In a study of 15 healthy adults exposed to cold stress, supplementation with 300 mg/kg of L-Tyrosine significantly protected working memory and marksmanship performance compared to placebo, despite lowered core body temperature.
The doses of L‑Tyrosine used in clinical trials addressing stress‑related brain fog and cognitive performance are typically 2,000 to 5,000 mg per day.
