Why Supplements Matter in Parkinson’s
Living well with Parkinson’s means paying attention to more than medication — it means caring for your body from the inside out. Nutrition is one of the most powerful tools you have to support strength, energy, and resilience. While food alone can’t treat or cure Parkinson’s, eating well and using evidence-based supplements can make a real difference to how you feel day to day.
Parkinson’s affects everyone differently, but there are a few reasons why nutrition takes on special importance.
1. Managing Energy and Fatigue
Many people with Parkinson’s experience fatigue — a deep, persistent tiredness that medication alone doesn’t fully address. Good nutrition helps support energy production at the cellular level. Nutrients like B vitamins (especially B12, B6, and folate), magnesium, and iron all contribute to normal energy metabolism.
Over time, even small nutritional imbalances can lead to energy dips. Supplements can help bridge those gaps, especially if appetite is reduced or eating full meals becomes more difficult.
2. Supporting the Brain and Nervous System
Parkinson’s is a condition that affects the brain’s ability to produce dopamine, a neurotransmitter that coordinates movement and mood. While supplements can’t replace dopamine, they can nourish the brain and nervous system to support its normal function.
-
B vitamins help maintain nerve health and contribute to psychological and cognitive performance.
-
Omega-3 fatty acids, found in fish oil and algal oil, help maintain the structure of brain cell membranes.
-
Choline and phosphatidylserine support neurotransmitter activity and communication between brain cells.
-
Antioxidants such as vitamin C, vitamin E, and Coenzyme Q10 help protect neurons from oxidative stress — a process linked to cellular ageing and damage.
Together, these nutrients help create the conditions for better cognitive function, focus, and mental clarity.
3. Protecting Bone and Muscle Strength
Falls and fractures are more common in Parkinson’s, partly due to postural changes, stiffness, and weaker muscles. Adequate intake of vitamin D, calcium, and protein is essential to maintaining bone and muscle health.
Many people with Parkinson’s are found to have low vitamin D levels, particularly in the UK and other northern climates where sunlight is limited. Vitamin D helps your body absorb calcium and contributes to normal muscle function — two key factors in maintaining balance and stability.
Taking a vitamin D supplement (especially vitamin D3, the most effective form) can help support stronger bones and muscles, reducing the risk of weakness and falls.
4. Supporting the Gut–Brain Connection
Digestive health is an often-overlooked aspect of Parkinson’s. Constipation and slow digestion are very common symptoms due to reduced gut motility and changes in the microbiome — the community of bacteria that live in your intestines.
The gut–brain axis describes how the digestive system communicates with the brain through nerves, hormones, and immune signals. When the gut is out of balance, it can affect energy, mood, and even how well medications work.
A diet rich in fibre (vegetables, fruit, oats, legumes) and fermented foods (such as kefir, sauerkraut, or miso) can help, but for many people, a probiotic supplement is a practical way to support gut balance. Probiotics help promote regularity and digestive comfort while supporting the immune system.
5. Balancing Nutrient Absorption Affected by Medication
Some Parkinson’s medications — particularly levodopa — can interfere with the absorption or metabolism of nutrients such as vitamin B12, folate, and sometimes iron. This means that even if you eat a balanced diet, your body might not fully absorb what it needs.
Supplements can help maintain healthy levels of these nutrients and prevent secondary issues such as fatigue, tingling sensations, or mood changes that can occur with deficiencies.
6. Supporting the Immune System and Overall Vitality
Parkinson’s can make it harder for the body to fight infections or recover from illness. Nutrients like vitamin C, vitamin D, and zinc play key roles in maintaining normal immune function.
Antioxidants such as vitamin E and CoQ10 also help protect cells from oxidative stress — a process that contributes to cellular ageing.
By supporting the immune system and cell health, good nutrition can improve resilience and help you stay well for longer.
7. Why Supplements Matter
Even with the best intentions, maintaining perfect nutrition every day isn’t easy. Parkinson’s can affect appetite, digestion, and nutrient absorption — making supplementation a valuable tool for filling those gaps safely and effectively.
Supplements can:
-
Support overall energy and vitality
-
Provide consistent, measurable nutrient intake
-
Compensate for reduced dietary variety or absorption issues
-
Complement (not replace) medical treatment
The key is quality — choosing evidence-based, well-formulated products made to GMP standards. At PDWellbeing, all supplements are designed with these needs in mind, providing clean, plant-based ingredients that support the unique challenges faced by people with Parkinson’s.
Common Nutrient Gaps and key supplements in Parkinson’s
Because Parkinson’s can affect how your body absorbs and uses nutrients, certain vitamins, minerals, and fatty acids are more likely to run low — even with a balanced diet. Addressing these gaps can help maintain strength, energy, and overall wellbeing. In this section, we’ll explore the nutrients most commonly affected in Parkinson’s, the science behind their benefits, and the supplements that can help restore balance and support everyday health.
1. Vitamin D3 – Strength, Immunity, and Mobility
Why it matters:
Vitamin D contributes to the maintenance of normal bones, normal muscle function, and immune system performance. It also plays a role in cognitive and mood health.
Why it’s often low in Parkinson’s:
Low vitamin D levels are common across the UK population but occur even more frequently in people with Parkinson’s. There are several reasons for this:
-
Less time outdoors due to reduced mobility or fatigue
-
Weaker sunlight exposure, particularly in winter months
-
Possible metabolic or inflammatory factors related to Parkinson’s itself (research in this area is ongoing)
The impact:
Low vitamin D is linked to weaker bones, reduced muscle strength, and a higher risk of falls — issues already more prevalent in Parkinson’s. Some studies have also suggested associations between low vitamin D and poorer balance or mood.
How to address it:
Supplementing with vitamin D3 (cholecalciferol) is the most effective way to raise and maintain healthy levels. Public Health England advises that everyone take vitamin D during winter, and people who are older or less mobile should consider year-round supplementation.
Recommended support:
A daily D3 supplement can help maintain steady levels and support the foundations of strength, balance, and immunity.
2. B Vitamins – Energy and Nerve Support
Why they matter:
The family of B vitamins supports energy metabolism, nerve function, and red blood cell production. Of particular relevance to Parkinson’s:
-
Vitamin B12 contributes to the normal function of the nervous system and helps reduce tiredness and fatigue.
-
Folate (vitamin B9) works alongside B12 to support brain and cell health.
-
Vitamin B6 contributes to the normal synthesis of neurotransmitters.
Why they’re often low:
Levodopa and other Parkinson’s medications can reduce levels of B12 and folate over time. Reduced stomach acid (a natural part of ageing) also affects how B12 is absorbed from food.
The impact:
Low B12 can cause fatigue, tingling sensations, balance issues, or memory problems — symptoms that can easily be mistaken for Parkinson’s progression. Low folate may contribute to anaemia and cognitive decline.
How to address it:
Ask your healthcare provider to test your B12 and folate levels annually. A high-quality B-complex or targeted B12 supplement can help maintain optimal levels and support the nervous system.
Recommended support:
A daily B-complex or multivitamin with active forms (methylcobalamin and methylfolate) for better absorption.
3. Omega-3 Fatty Acids – Brain, Mood, and Heart Health
Why they matter:
Omega-3 fatty acids (EPA and DHA) play key roles in maintaining brain structure and normal heart function. They also help regulate inflammation and support cognitive performance.
Why they’re often low:
Most people don’t consume enough oily fish — the richest dietary source of omega-3s. Those following vegetarian or low-fat diets are at even greater risk of deficiency.
The impact:
Low omega-3 intake may affect mood, memory, and overall resilience — areas of particular concern for people with Parkinson’s. Research also suggests omega-3s may help support a healthy inflammatory response.
How to address it:
Include oily fish like salmon, sardines, and mackerel 2–3 times per week. If you don’t eat fish, try a daily algal oil supplement — a sustainable, vegan source of EPA and DHA.
Recommended support:
A plant-based omega-3 supplement to bridge dietary gaps and support brain and heart health.
4. Probiotics and Gut Health – The Gut–Brain Connection
Why they matter:
The gut is sometimes called the “second brain.” It’s lined with millions of neurons and communicates directly with the brain via the gut-brain axis — a two-way communication pathway that affects mood, digestion, and even medication response.
Why gut issues are common in Parkinson’s:
Constipation and bloating are frequent symptoms due to slower gut motility. Emerging research also shows that Parkinson’s is associated with changes in the gut microbiome — the community of bacteria living in the digestive system.
Some studies suggest that these imbalances may contribute to a “leaky gut”, where the intestinal lining becomes more permeable than normal. This may allow inflammatory compounds or bacterial by-products to enter the bloodstream, potentially influencing inflammation in the body and brain. While research continues, supporting gut integrity and microbial balance is an important aspect of wellbeing.
The impact:
An imbalanced gut can cause digestive discomfort, reduce absorption of nutrients, and potentially affect how Parkinson’s medications like levodopa are absorbed.
How to address it:
-
Eat a diet rich in fibre (vegetables, legumes, oats, and fruit).
-
Stay hydrated.
-
Include prebiotic foods such as bananas, onions, garlic, and flaxseed.
-
Consider a probiotic supplement containing multi-strain beneficial bacteria (e.g., Lactobacillus and Bifidobacterium) to help rebalance the microbiome and improve regularity.
Recommended support:
A probiotic-prebiotic combination to restore gut balance and support healthy communication along the gut-brain axis.
5. Antioxidants – Cellular Protection and Energy
Why they matter:
Oxidative stress is a natural part of metabolism, but in Parkinson’s, it may occur at higher levels due to changes in mitochondrial (cellular energy) function. Antioxidants help protect cells from this stress, supporting energy production and overall vitality.
Key nutrients:
-
Vitamin C – contributes to the protection of cells from oxidative stress and supports the immune system.
-
Vitamin E – helps maintain healthy cell membranes.
-
Coenzyme Q10 (CoQ10) – supports mitochondrial energy production and may assist with fatigue.
The impact:
Low antioxidant intake can contribute to tiredness, reduced cell function, and potentially greater oxidative damage over time.
How to address it:
Eat a variety of colourful fruits and vegetables (berries, spinach, peppers, broccoli) and consider antioxidant-supporting supplements for additional protection.
Recommended support:
A balanced antioxidant formula or multivitamin including vitamin C, E, and CoQ10 for daily cellular defence.
6. Magnesium, Iron, and Trace Minerals
Why they matter:
Minerals like magnesium, iron, and zinc support energy metabolism, muscle function, and immune health.
Why they’re often low:
Reduced appetite, constipation, or malabsorption can lead to mild deficiencies. Some medications may also alter mineral balance.
The impact:
-
Low magnesium can cause muscle cramps, poor sleep, or fatigue.
-
Low iron can lead to anaemia and low energy.
-
Low zinc can affect immune function and wound healing.
How to address it:
Include leafy greens, beans, nuts, seeds, and whole grains in your diet. A well-rounded multivitamin or mineral supplement can help ensure you’re meeting daily needs.
7. Protein Timing and Medication Absorption
Why it matters:
Protein is vital for muscle maintenance, but it can sometimes interfere with the absorption of levodopa — the main medication used in Parkinson’s.
Why it’s important:
Levodopa and certain amino acids (the building blocks of protein) compete for absorption in the gut and at the blood–brain barrier. If levodopa is taken with a high-protein meal, it may not work as effectively.
How to address it:
Try taking levodopa 30–60 minutes before meals or scheduling higher-protein meals later in the day. Always check with your neurologist or Parkinson’s nurse before making changes.
Recommended support:
A nutrition plan that balances protein across the day — enough for muscle maintenance without interfering with medication.
Choosing the Right Supplements
Not all supplements are created equal. When choosing products, keep these points in mind:
-
✅ Quality and safety – Always choose supplements made to Good Manufacturing Practice (GMP) standards, ideally in the UK or EU. These regulations ensure the product has been tested for purity, consistency, and safety. Avoid products that make unproven medical claims or lack transparency about ingredients.
-
✅ Evidence-based ingredients – Focus on nutrients with well-established benefits for general health and wellbeing — such as vitamin D for bones and muscles, B vitamins for energy and nerve function, omega-3s for brain and heart health, and probiotics for gut balance. Avoid supplements that claim to “cure” or “reverse” Parkinson’s, as no such product has been scientifically validated. Instead, look for formulas that complement a healthy lifestyle and medical care.
-
✅ Consider absorption and bioavailability– The best supplement in the world won’t help if your body can’t absorb it. Look for highly bioavailable forms — for example, vitamin D3 rather than D2 (even better if derived from a natural source such as algae), methylcobalamin instead of synthetic B12, and algal omega-3 as a clean, absorbable alternative to fish oil. Some products also include black pepper extract (piperine) to improve absorption of certain nutrients.
-
✅ Match supplements to your individual needs - Not every person with Parkinson’s will need the same nutrients. Your ideal supplement plan depends on your diet, medication, symptoms, and lifestyle. For example, someone struggling with fatigue may benefit from extra B vitamins, while another person with digestive issues might focus on probiotics and fibre. A pharmacist or registered dietitian can help tailor your plan.
-
✅ Keep it simple and consistent – It’s better to take a few high-quality supplements consistently than a large number sporadically. Look for combination formulas designed to support multiple areas of health — like PDWellbeing’s targeted brain, gut, and energy support blends.
Safety and Talking to Your Healthcare Team
Supplements should never replace prescribed Parkinson’s medications, but they can work alongside them as part of a holistic wellbeing plan.
Before starting a new supplement, always:
-
Talk to your GP, pharmacist, or specialist — they can check for interactions with your medications.
-
Stick to the recommended daily amounts — more isn’t always better, and high doses of some vitamins can be harmful.
-
Monitor how you feel and review supplements regularly. Your needs may change over time.
