1. Vitamin B12 (Cobalamin)
Why it matters:
Vitamin B12 plays a crucial role in the formation of the myelin sheath and supports nerve signal transmission throughout the brain and spinal cord.
New 2025 research:
A UCSF study revealed that even people with “normal” B12 levels showed higher rates of white-matter damage and slower cognitive processing if their active B12 form was low.

Found in:
Beef, lamb, salmon, tuna, eggs, dairy, and fortified yeast extracts.
2. Vitamins B9 (Folate) and B6 (Pyridoxine)
Why they matter:
These B-vitamins regulate homocysteine levels, improve blood flow in the brain, and support neuron metabolism.
New 2025 research:
Cleveland-based University Hospitals reported that regular intake of B6, B9, and B12 helps maintain cognitive performance and may reduce the risk of neurodegenerative changes.

Found in:
Leafy greens (spinach, kale), legumes (lentils, chickpeas), poultry, and whole grains.
3. Vitamin K (especially K2)
Why it matters:
Vitamin K supports neuronal survival, reduces inflammation, and may limit amyloid-β buildup linked to Alzheimer’s.
New 2025 research:
An MDPI study highlighted Vitamin K’s protective role against oxidative stress and neuroinflammation in brain tissue.

Found in:
Spinach, broccoli, fermented foods (natto, sauerkraut), and egg yolk.
4. Vitamin D
Why it matters:
This vitamin acts directly on neurons and glial cells, promoting neuroprotection and healthy nerve signaling.
New 2024 study:
Findings published in Neurobiology of Disease (2024) suggest Vitamin D plays an essential role in protecting against age-related neural degeneration.

Found in:
Sunlight exposure, sardines, mackerel, fortified milk, and egg yolk.
5. Vitamin E (Tocopherol)
Why it matters:
A powerful antioxidant that protects nerve cells from oxidative stress and helps preserve memory.
New 2025 research:
Recent studies show that Vitamins E and C work together to reduce oxidative damage and improve nerve health.
(Source: IJBR 2025)
Found in:
Almonds, hazelnuts, olive oil, avocado, and spinach.
6. Vitamin C (Ascorbic Acid)
Why it matters:
Supports neurotransmitter synthesis and acts as a strong antioxidant in the central nervous system.
New 2025 research:
The same IJBR 2025 review confirmed that Vitamin C plays a major role in protecting neurons from oxidative damage.
(Source: IJBR 2025)
Found in:
Citrus fruits, berries, bell peppers, and broccoli.
7. Omega-3 Fatty Acids (DHA and EPA)
Why they matter:
Though not a vitamin, DHA is critical for brain-cell membrane health and cognitive function.
New 2025 research:
A Frontiers in Molecular Biosciences paper found that nutrient-rich diets high in DHA improve neuroplasticity and memory.
(Source: Frontiers 2025)
Found in:
Salmon, herring, walnuts, flaxseed, and algae oils.
8. Magnesium
Why it matters:
Involved in hundreds of enzymatic reactions, it helps regulate nerve signaling and muscle function.
New 2025 research:
The Sun reported that magnesium L-threonate may improve sleep quality and protect the brain against early Alzheimer’s development.
(Source: The Sun Health 2025)
Found in:
Spinach, almonds, beans, and whole grains.
9. Vitamin B3 (Niacin / Nicotinamide)
Why it matters:
Boosts NAD+ production, supports brain-cell energy, and reduces neuroinflammation.
New 2025 research:
A Verywell Health article cited experiments showing that B3 plus green tea (EGCG) rejuvenated aging neurons and reduced amyloid plaque formation.
(Source: Verywell Health 2025)
Found in:
Whole grains, lentils, chicken, and fish.
10. Vitamins B5 (Pantothenic Acid) and B7 (Biotin)
Why they matter:
B5 aids in neurotransmitter synthesis; B7 supports fatty acid metabolism and myelin formation.
New research update:
Emerging 2025 studies explore high-dose biotin for myelin repair and nerve regeneration in neurodegenerative conditions.
(Source: Wikipedia / PubMed updates 2025)
Found in:
Sunflower seeds, mushrooms, egg yolk, nuts, and whole grains.
Final Thoughts
Vitamins and micronutrients aren’t miracle cures — but 2024-2025 research shows they can make a real difference for brain function and nerve health when combined with balanced nutrition, sleep, and exercise.
Always consult a qualified health professional before starting supplements, and opt for natural food sources whenever possible.
