Among the most crucial nutrients for neurological health are B vitamins, particularly B12, B6, and folate (B9).
These essential vitamins support dopamine production, reduce inflammation, and lower homocysteine levels, which is important for brain and cardiovascular health. However, deficiencies in B vitamins are common among Parkinson’s patients, as I’ve seen in some of my clients and can contribute to cognitive decline, tremors, and neuropathy.
Why Are B Vitamins Essential for Parkinson’s Disease?
B vitamins play an important role in brain function, helping to:
✅ Support dopamine production, which is crucial for movement and mood stability.
✅ Reduce homocysteine levels, a marker of inflammation and neurodegeneration.
✅ Support nerve function, reducing the risk of neuropathy and cognitive decline.
✅ Promote energy production, helping to fight fatigue.
For those with Parkinson’s Disease, ensuring optimal B-vitamin intake can help support brain function and manage symptoms effectively.

Vitamin B12: The Brain-Boosting Nutrient
Vitamin B12 is critical for nerve function and red blood cell production. However, B12 deficiency can be a cause for cognitive decline.
Signs of B12 Deficiency
🚨 Memory loss and confusion
🚨 Numbness or tingling in hands and feet
🚨 Fatigue and weakness
🚨 Balance issues
Best B12-Rich Foods
🥩 Oily fish – Salmon, sardines, and trout
🥚 Eggs – A convenient source of B12 and choline
🥛 Dairy – Yogurt and cheese contain moderate amounts
🍄 Fortified plant-based foods – Nutritional yeast and fortified plant milks
For individuals with low B12 levels, supplementation may be necessary. Book a Discovery Call to discuss testing and personalised recommendations.
Vitamin B6: Supporting Dopamine and Energy
Vitamin B6 is essential for dopamine synthesis, the neurotransmitter that Parkinson’s Disease affects. It also supports immune function and brain health.
Signs of B6 Deficiency
🚨 Low energy and brain fog
🚨 Irritability or depression
🚨 Muscle weakness
Best B6-Rich Foods
🐟 Tuna & salmon – Rich in both B6 and omega-3s
🥑 Avocados – A great source of B6 and healthy fats
🥔 Sweet potatoes – A delicious, fibre-rich option
🍌 Bananas – A convenient snack with B6 and potassium
Folate (B9): Protecting Cognitive Function
Folate is essential for DNA repair, brain health, and detoxification. It plays a role in reducing homocysteine, which, at high levels, can increase inflammation and neurodegeneration.
Signs of Folate Deficiency
🚨 Memory problems
🚨 Weakness or fatigue
🚨 Poor digestion
Best Folate-Rich Foods
🥬 Leafy greens – Spinach, kale, and Swiss chard
🍊 Citrus fruits – Oranges and grapefruits
🌾 Legumes – Lentils and chickpeas
