What Is Parkinson’s?

Parkinson’s disease is a progressive disorder affecting the nervous system. It impacts movement, often starting with a barely noticeable tremor in one hand. As the condition advances, it can lead to stiffness or slowing of movement. Symptoms vary but usually include tremors, muscle stiffness, and impaired posture and balance. People with Parkinson’s may also experience changes in speech and writing.

The exact cause of Parkinson’s is unknown, but several factors appear to play a role, including genetics and environmental triggers. For example, exposure to certain toxins or a history of head injury might increase the risk. Age is another important factor, with Parkinson’s typically developing in middle or later years.

It’s important to recognize that Parkinson’s symptoms and their intensity can vary widely among people. Early signs might be mild and go unnoticed. Slowed movement (bradykinesia) is a hallmark of Parkinson’s, often starting with reduced facial expressions or less arm swing when walking. Tremors usually begin in a limb, often the hand or fingers. Muscle stiffness can occur in any part of the body, and impaired posture and balance are common, leading to a higher risk of falls.

Parkinson’s is a complex condition with no cure, but treatments are available to manage symptoms. These treatments often involve medications, but surgical therapies might be an option in some cases. Early diagnosis and tailored treatment plans are crucial for managing Parkinson’s effectively.

What Food and Lifestyle Factors Are Important For Managing Parkinson’s?

  • Optimal Food Choices: A high-nutrient diet supports overall health. People with Parkinson’s benefit from a diet rich in fruits, vegetables, whole grains, and lean proteins. Omega-3 fatty acids, found in fish like salmon and mackerel, can be beneficial. It’s also important to stay hydrated.
    • Fiber Intake: Constipation is a common issue in Parkinson’s, so a high-fiber diet can help. This includes foods like whole grains, legumes, vegetables, and fruits.
    • Bone Health: Parkinson’s can increase the risk of osteoporosis, so calcium and vitamin D are important. Sources include dairy products, leafy green vegetables, and sunlight exposure for vitamin D synthesis.
  • Physical Activity: Regular exercise helps maintain muscle strength, flexibility, and balance. Activities like walking, tai chi, and yoga can be particularly beneficial.
  • Mental Well-being: Stress management and mental health are crucial. Practices like meditation, mindfulness, or engaging in hobbies can help manage stress and improve mood.
    • Social Engagement: Staying socially active supports emotional health. Joining support groups or engaging in community activities can be beneficial.
  • Regular Sleep: Parkinson’s can disrupt sleep, so practicing good sleep hygiene is important. This includes maintaining a regular sleep schedule, creating a comfortable sleeping environment, and avoiding caffeine and electronics before bed.
  • Limiting Alcohol and Tobacco: Reducing intake of alcohol and avoiding tobacco can help manage symptoms.
  • Safety Measures at Home: To prevent falls, it’s important to ensure a safe living environment. This might involve installing grab bars in bathrooms, removing tripping hazards, and ensuring good lighting.

For people with Parkinson’s disease, certain nutritional supplements may help manage symptoms and support overall health. Here are some commonly recommended supplements that may be particularly helpful in supporting Parkinson’s:

  • Multivitamin: Your multivitamin should provide the following nutrients:
    • B Vitamins: Particularly B12 and folate, as they are essential for nerve health and cognitive function. People with Parkinson’s may have higher requirements for these vitamins.
    • B6 Caution: Vitamin B6 in high doses can reduce the effectiveness of Levodopa, so supplements containing large amounts of this vitamin should be avoided.
      Vitamin B12: “PD patients with vitamin B12 levels <587 ng/L were 5.4 times more likely to develop dementia, with 50% having dementia within 5 years of PD diagnosis compared with 11% in those with a vitamin B12 level of ≥587 ng/L (p < 0.05).” [PMID: 32203914]
    • Folate: Folate, as well as B12 supplementation, reduces elevated homocysteine, a marker of inflammation. [PMID: 33992189][PMC10628521]
    • Vitamin D: Vitamin D deficiency is common in Parkinson’s patients and can contribute to bone health issues and possibly worsen symptoms. Supplementing with vitamin D may help improve these aspects. Vitamin D deficiency seems to be related to disease severity and disease progression. [PMC8953648]
    • Zinc: Important for overall brain health, zinc supplementation is considered by some, particularly if dietary intake is inadequate. Parkinson’s patients have lower zinc levels and greater symptoms of zinc deficiency. [PMID: 10100031]
    • Selenium: An antioxidant that may help protect neurons. [PMID: 37995510] [PMID: 27556332]
    • Vitamin E: An antioxidant that can help combat oxidative stress in the brain, though high doses should be avoided as they may have adverse effects. [PMID: 28342967]
  • N-Acetyl Cysteine (NAC): An antioxidant that may help with oxidative stress. NAC is shown to improve dopamine function along with significantly improved PD symptoms (P < 0.0001). [PMID: 31206613]
  • Mucuna Pruriens: Contains natural levodopa, a precursor to dopamine, which is depleted in Parkinson’s disease. Some patients use it as a natural alternative to synthetic levodopa medications. [PMC5539737]
  • Curcumin (from Turmeric): Known for its anti-inflammatory properties, curcumin might have neuroprotective benefits in Parkinson’s. [PMC8537234] A study of 19 patients with PD showed a significant effect of curcumin supplementation in decreasing the worsening of the Parkinson’s symptoms. [PMC9210322]
  • Omega-3 Fatty Acids: Found in fish oil, these fatty acids can help reduce inflammation and are believed to support overall brain health. Use of 1000 mg of flaxseed oil with 400 mg Vitamin E was also effective in improving Parkinson’s symptoms. [PMID: 28342967]
  • Melatonin: Helpful for sleep disturbances, which are common in Parkinson’s disease. [PMC8855052]
  • Probiotics: Gut health is increasingly recognized as important in Parkinson’s as constipation is a very common problem in PD. [PMC10015253] Fiber works synergistically with probiotics in maintaining a healthy gut microbiome. [PMC9871263] The gut microbiome affects folate and homocysteine levels in a way that is linked to Parkinson’s development. [PMID: 33657381]
  • Green Tea Extract (EGCG): Rich in antioxidants, specifically epigallocatechin gallate (EGCG), which may have neuroprotective properties.
  • Magnesium: Can be beneficial for muscle stiffness and cramps, common symptoms in Parkinson’s disease. Magnesium L-Threonate has been shown to more effectively cross the blood-brain barrier. A study of a Parkinson’s animal model showed that Magnesium L-Threonate reduced movement deficits and the loss of dopamine neurons. [PMC6857673]
  • L-Theanine: Found in tea leaves, L-Theanine can promote relaxation and help with anxiety and sleep issues. It also reduced movement deficits in an animal model of Parkinson’s. [PMID: 34210222]
  • Ginkgo Biloba: Sometimes suggested for cognitive issues, though The evidence of ginko’s effectiveness in Parkinson’s is limited to animal models. [PMID: 35532872]
  • Lion’s Mane Mushroom: Used for its potential neuroprotective and cognitive-enhancing properties. Animal models show it to be effective in Parkinson’s. [PMC5987239]
  • Ashwagandha: An adaptogenic herb used in Ayurvedic medicine, it’s believed to have stress-reducing and neuroprotective effects. [PMC10147008]
  • Cannabidiol (CBD): Some individuals with Parkinson’s use CBD for its potential to alleviate symptoms such as pain, sleep disturbances, and anxiety, although research is still emerging.

What Supplements Didn’t Work for Parkinson’s?

  • Coenzyme Q10 (CoQ10): Some studies suggest CoQ10 might help in slowing the progression of Parkinson’s disease due to its role in mitochondrial function and its antioxidant properties. However, a 2016 review of blinded studies showed no benefit in symptoms or slowing functional decline. [PMID: 26553164]
  • Creatine: Has shown some potential in neuroprotective studies, but has not been shown to be effective in Parkinson’s disease specifically. [PMC4349346]

Parkinson’s Medications and Their Interactions with Food

Managing Parkinson’s disease involves medications, and understanding how these interact with certain nutrients and supplements is important. Each type of Parkinson’s medication can have different interactions, which necessitates careful food and supplement choices.

  • Levodopa/Carbidopa:
    • Protein: Protein-rich foods can interfere with the absorption of Levodopa. Choose lower protein foods during the time of day when medication is needed most. Eat extra protein at night to help meet nutritional needs.
    • Take on an Empty Stomach: It’s recommended to take this medication either 30 minutes before or 60 minutes after meals.
    • Vitamin B6: In high doses, B6 can reduce the effectiveness of Levodopa, so supplements containing large amounts of this vitamin should be avoided.
  • Dopamine Agonists (e.g., Ropinirole, Pramipexole): While specific nutrient interactions are less prominent with dopamine agonists, these medications can cause drowsiness.
  • MAO-B Inhibitors (e.g., Selegiline, Rasagiline): These medications can interact with tyramine-rich foods, like aged cheeses and certain processed meats, leading to potentially dangerous blood pressure spikes.
  • COMT Inhibitors (e.g., Entacapone): There are no specific dietary restrictions with COMT inhibitors, but they can enhance the side effects of Levodopa, so the same dietary considerations for Levodopa/Carbidopa apply.
  • Anticholinergics (e.g., Trihexyphenidyl): These medications can cause dry mouth and constipation, so a diet high in fiber with plenty of fluids is beneficial. Fiber supplements can also help, but they should be taken a few hours apart from the medication to avoid interference with absorption.
  • Amantadine: This medication can cause dry mouth and constipation, similar to anticholinergics. A diet rich in fiber and fluids is advised.

Food First!

Although this article discusses supplements in detail, don’t forget that we are absolutely committed to the “Food First” approach to nutrition. When it comes to your health, the totality of your eating habits far surpasses the impact of individual nutrients or any single supplement you consume. Even though this article doesn’t delve into the broader picture of your overall diet, it’s crucial to keep this element at the forefront of our minds. Your food needs to provide all the vitamins, minerals, fiber, and phytochemicals to nourish your body systems down to the cellular level.

Food choices, rather than supplements, are the most critical factors for a healthy gut microbiome. These trillions of tiny inhabitants in your gut affect your brain waves; they orchestrate your immune system. They possess the power to create molecules that can switch genes on or off and are even capable of synthesizing neurotransmitters. Opting for organic foods and steering clear of plastic packaging (including those labeled BPA-free) is a smart move to limit toxin exposure. The sum of all these parts leads to a powerful conclusion: the ultimate key to your health lies in the quality and balance of the food you consume. Supplements are secondary.

What Lab Tests Might Be Helpful In Managing Parkinson’s?

Managing Parkinson’s disease often involves a combination of clinical assessments and laboratory tests to monitor overall health and the progression of the condition. Certain tests can be helpful in managing the disease:

  • Blood Tests: These can rule out other conditions that may mimic Parkinson’s symptoms. They can check for various factors, including vitamin and mineral levels (like Vitamin D and B12), liver and kidney function, and thyroid function.
  • Uric Acid Levels: Some studies suggest that uric acid levels might be associated with Parkinson’s progression, but more research is needed in this area.

To Sum It Up

Nutritional supplements offer a promising adjunct to traditional treatments for Parkinson’s disease. From potentially alleviating symptoms to possibly slowing disease progression, these supplements, including vitamins, minerals, and antioxidants, could play a significant role in a comprehensive management plan. However, it’s important to remember that while supplements can provide benefits, they are not a cure and should be used in conjunction with prescribed medications and therapies. Given the complexities of Parkinson’s and the individual nature of its progression, consulting a Registered Dietitian is crucial. A dietitian can provide personalized advice on supplement use, ensuring it aligns with your overall health needs and medical treatments. We encourage readers to seek further information and guidance from a Registered Dietitian to make informed decisions about using nutritional supplements for Parkinson’s disease.
