Can you age-proof your brain? Nutrients that support cognitive health

Incorporating these six key nutrients in your diet can progressively support brain health and contribute to anti-ageing effects

Cognitive decline can begin anytime after your midlife, however, at the age of 60 is usually when it occurs. Cognitive decline can affect memory, focus, and decision-making—functions that define an individual’s sense of independence, identity, and quality of life. While ageing is inevitable, certain foods may reverse premature ageing, especially in the brain.  

Nutrition is closely linked to cognitive resilience. Antioxidants, essential fats, and specific vitamins protect neurons, reduce inflammation, and support repair and regeneration. 

The Brain-Nutrient Connection

Like the rest of the body, the brain requires specific nutrients to function at its most optimal. Our diet plays a significant role, influencing everything from information processing to memory retention. With age, symptoms of brain ageing—such as slower cognitive response, reduced memory capacity, and difficulty in concentrating—become more common. These changes are often linked to oxidative stress, inflammation, and declining neurotransmitter levels, all of which accelerate the ageing process. 

Targeted nutrition can help reverse premature brain ageing by delivering essential antioxidants, healthy fats, and key vitamins and minerals. These nutrients support neuron protection, stimulate new cell growth, and enhance neural connectivity—slowing or potentially reversing the cognitive effects of ageing. Here are six nutrients that have been shown to support brain health and contribute to anti-ageing effects. 

Key Nutrients for Cognitive Health

Omega-3 Fatty Acids

Omega-3s, particularly DHA, form a major part of brain cell membranes. Omega-3s have been proven to improve memory, reduce inflammation, and help slow the progression of neurodegenerative diseases.

Sources: Fatty fish (such as salmon), flaxseeds and flaxseed oil, walnuts, chia seeds, algal oil (a plant-based omega-3 supplement)

Antioxidants (Vitamins C and E)

Oxidative stress accelerates brain ageing. Antioxidants neutralise free radicals and protect neural tissue from damage. Vitamin C supports overall brain health by boosting immune function and supporting blood flow to the brain, while vitamin E helps protect brain cell membranes from damage. Together, they help combat oxidative stress, a major contributor to brain ageing and cognitive decline.

Sources:

Vitamin C: Citrus fruits, strawberries, bell peppers, spinach

Vitamin E: Almonds, sunflower seeds, spinach, and avocados

B Vitamins (B6, B12, Folate)

These vitamins reduce homocysteine levels—a marker linked to cognitive decline—and support neurotransmitter synthesis. Dopamine and GABA (gamma-aminobutyric acid) are neurotransmitters essential for mood regulation, memory, and cognitive function. Folate and B12 also play a vital role in DNA synthesis and repair—processes that become more important with age. 

Sources:

B6: Chicken, bananas, potatoes

B12: Meat, fish, dairy products, fortified cereals

Folate: Leafy greens, legumes, fortified grains

Vitamin D

Vitamin D supports neuron growth and reduces brain inflammation. Low levels are associated with cognitive impairment and higher risk of Alzheimer’s disease. Vitamin D supports the production of neurotrophins—proteins that promote the growth and survival of neurons. It also helps reduce brain inflammation, a key contributor to cognitive decline.  so plays a role in reducing inflammation in the brain, which is linked to cognitive decline.

Sources:

• Sunlight exposure (the body naturally produces vitamin D when exposed to the sun)

• Fatty fish, eggs, and fortified dairy products

• Vitamin D supplements (especially for individuals with limited sun exposure)

Flavonoids

These plant-based antioxidants promote the growth of new neurons and enhance memory and learning. Research shows that flavonoids enhance memory, learning, and cognitive function by supporting the growth of new neurons and strengthening communication between brain cells. They also offer protection against age-related decline and neurodegenerative diseases. 

Sources: Berries (blueberries, strawberries, blackberries), cocoa and dark chocolate, green and black tea, citrus fruits

Choline

Choline is essential for brain health, supporting the production of acetylcholine—a neurotransmitter vital for memory and learning. Adequate levels are linked to sharper mental clarity and a lower risk of cognitive decline. While crucial during pregnancy for fetal brain development, choline continues to play a key role in maintaining cognitive function throughout life. Including choline-rich foods into your diet can reverse premature ageing by supporting both brain function and physical vitality, making it a crucial component of a natural anti-ageing strategy.

Sources: Eggs (one of the richest sources of choline), lean meats like chicken and turkey, fish, soybeans, and tofu

Enhancing Brain Health with Nutritional Choices

• Fatty fish supports long-term memory.

• Berries and leafy greens reduce oxidative stress.

• Eggs and fortified grains aid neurotransmitter production.

• Sunlight exposure helps maintain optimal vitamin D levels.

Together, these foods support the brain’s structural integrity and functional longevity.

Lifestyle Factors That Complement Nutrition 

Physical Activity: Enhances blood flow to the brain and supports neurogenesis.

Mental Stimulation: Activities like reading, solving puzzles, and skill-building maintain cognitive sharpness.

Mindfulness Practices: Reduce stress, and enhance attention span and brain health.
