Optimal brain performance depends on more than rest and hydration—it requires the right blend of nutrients to fuel neurotransmitters, protect neurons, and manage stress. From adaptogens to amino acids, here are some of the most research-backed ingredients shown to support cognitive health, with explanations of how they work and where to find them in food when possible.
Niacin
Niacinamide, a form of Vitamin B3, supports brain health by boosting NAD⁺ levels—essential for cellular energy production and DNA repair. It helps maintain healthy mitochondria in brain cells, reducing oxidative stress and inflammation. Some studies suggest it may support cognitive resilience and help slow age-related neurological decline. It’s particularly useful for supporting overall metabolic function in the brain.
Food sources include:
Chicken breast, turkey, tuna, salmon, peanuts, mushrooms, brown rice, and fortified cereals.
Vitamin B6
Vitamin B6 is essential for synthesizing neurotransmitters like dopamine, serotonin, and GABA, which influence mood, memory, and attention. It also plays a role in reducing homocysteine, a compound linked to brain shrinkage and cognitive dysfunction when elevated. Low B6 levels have been associated with mental fatigue and poor memory. Supplementation may support brain development, emotional balance, and cognitive performance, especially under stress.
Food sources include:
Bananas, chicken, salmon, tuna, avocados, potatoes, and spinach.
DMAE Bitartrate (Dimethylaminoethanol)
DMAE is a choline analog that may help increase levels of acetylcholine—a neurotransmitter vital for learning, memory, and attention. Acetylcholine helps neurons communicate efficiently, especially in the prefrontal cortex where focus and decision-making happen. DMAE may also support cell membrane stability and reduce oxidative stress. Some studies associate it with improvements in alertness, short-term memory, and mood.
Food sources:
Small amounts of DMAE occur naturally in oily fish like sardines and anchovies.
L-Glutamine
L-Glutamine is the most abundant amino acid in the body and plays a key role in nitrogen transport, energy production, and neurotransmitter balance. In the brain, glutamine is converted into glutamate (excitatory) and GABA (inhibitory), helping regulate neural communication. Under stress or illness, glutamine levels can decline, potentially affecting mood, cognition, and focus. It may also support gut health, which indirectly influences mental clarity via the gut-brain axis.
Food sources:
Beef, poultry, dairy products, eggs, spinach, parsley, beans, and cabbage.
GABA (Gamma-Aminobutyric Acid)
GABA is the brain’s primary inhibitory neurotransmitter, promoting calmness and reducing overactivity in the nervous system. Adequate GABA levels are linked to reduced anxiety, improved focus, and better sleep quality. While there is debate about whether supplemental GABA crosses the blood-brain barrier effectively, users often report a noticeable sense of calm and mental clarity.
Food sources:
Fermented foods (like yogurt, kimchi, miso), spinach, sweet potatoes, brown rice germ, and green tea may help support natural GABA production.
Bacopa Monnieri Extract
Bacopa is an adaptogenic herb traditionally used in Ayurvedic medicine for enhancing intellect and memory. Modern studies suggest it improves synaptic communication, supports antioxidant activity in the brain, and may increase the synthesis of key neurotransmitters like serotonin and acetylcholine. It has shown promise in improving memory retention, verbal recall, processing speed, and stress resilience—especially with long-term use.
Food sources:
Not typically found in Western diets; usually consumed through supplements or herbal preparations. Can be found in dietary supplements.
Green Tea Extract
Green tea extract combines two well-known brain-supporting compounds: caffeine, which promotes alertness and energy, and L-Theanine, an amino acid that enhances calm, sustained focus. Together, they improve reaction time, working memory, and cognitive accuracy without causing overstimulation. L-Theanine is also known to boost alpha brain waves—associated with relaxed mental clarity and creativity.
Food sources:
Green tea, matcha, black tea, and white tea (less concentrated).
Grape Seed Extract
Grape seed extract is rich in oligomeric proanthocyanidins (OPCs)—powerful antioxidants that protect brain cells from oxidative stress and may enhance blood flow to the brain. By improving vascular integrity and reducing inflammation, grape seed extract supports mental sharpness, especially in aging populations. Some research suggests it may also help with memory consolidation and neuroprotection.
Food sources:
Dark grapes (with seeds), red wine (in moderation), grape seed oil, and purple berries.
Bilberry Fruit Extract
Bilberries, a close relative of blueberries, are packed with anthocyanins that protect blood vessels and reduce inflammation. Bilberry extract supports visual acuity and retinal health, but also contributes to brain function by improving microcirculation. Enhanced blood flow to the brain may support focus, oxygen delivery, and cognitive performance.
Food sources:
Bilberries, blueberries, blackberries, elderberries, and other dark berries.
Huperzine A
Huperzine A is a natural compound that inhibits acetylcholinesterase—an enzyme that breaks down acetylcholine. By preserving this neurotransmitter, Huperzine A supports learning, memory retention, and neuroplasticity. It has been studied in both healthy individuals and those with mild cognitive impairment, with results showing potential benefits for attention and short-term memory. It also exhibits antioxidant and neuroprotective properties.
Food sources:
Not found in common dietary foods; extracted from the Chinese club moss (Huperzia serrata). Can be found in dietary supplements.
Phosphatidylserine
Phosphatidylserine is a phospholipid that makes up part of the structure of neuronal membranes. It helps maintain fluidity and signaling in brain cells, allowing for efficient transmission of electrical impulses. Supplementation has been associated with improved memory, focus, mental processing speed, and stress regulation—especially in aging populations or those under high cognitive demand.
Food sources:
Sunflower lecithin, soybeans, white beans, fatty fish (like mackerel and herring), and organ meats such as chicken liver.

Frequently Asked Questions (FAQ)
1. Can I get all of these brain-supporting ingredients from food alone?
Some nutrients—like B vitamins, magnesium, and antioxidants—are abundant in a balanced whole-foods diet. However, others like Huperzine A, Bacopa monnieri, and Phosphatidylserine are more difficult to obtain through food and are most effective when consumed in supplement form.
2. How long does it take to notice cognitive benefits from these ingredients?
Timeframes vary depending on the ingredient and individual. Caffeine and L-Theanine may provide immediate focus and alertness, while herbs like Bacopa and Phosphatidylserine often require consistent use over several weeks to show full effects. Long-term support is typically seen with regular intake.
3. Are these ingredients safe to combine?
Many of these ingredients are found together in cognitive support supplements and have been studied in combination. That said, individuals with medical conditions or those taking medications should consult a healthcare professional before beginning any new supplement routine.
4. Do these ingredients help with age-related memory loss?
Yes, ingredients like Huperzine A, Phosphatidylserine, Grape Seed Extract, and Bacopa Monnieri have been studied for their effects on cognitive decline in older adults. They support memory, focus, and brain cell protection, making them helpful for healthy aging.
5. What is the best time of day to take brain-supporting supplements?
It depends on the formula. Supplements containing caffeine or green tea extract are best taken in the morning or early afternoon to avoid interfering with sleep. GABA and L-Theanine, if taken alone, may also be used in the evening to promote calm and sleep.
6. Are there any side effects?
Most ingredients are well-tolerated when taken in appropriate doses. Mild side effects like headache, digestive discomfort, or jitteriness (from caffeine) can occur in sensitive individuals. Start with lower doses and increase gradually as needed.
7. Can these ingredients help with stress and mental fatigue?
Yes. L-Theanine, GABA, Bacopa, and Phosphatidylserine are known to reduce the effects of stress on the brain, improve mood balance, and support recovery from mental fatigue—making them beneficial for both daily focus and emotional resilience.
