A Naturopathic Approach to Parkinson’s Symptoms Using IV Glutathione

The following is a naturopathic case report summary of a patient with Parkinson’s symptoms who received intravenous (IV) glutathione therapy from her naturopathic doctor. There are many layers of a naturopathic approach to Parkinson’s; IV therapy is just one of the many ways this can be addressed (see more at the end of the article). This case report is for informational purposes only and should not be used to diagnose or self-treat Parkinson’s or any other condition.

Here’s What We Know about Parkinson’s

  • Chronic exposure to toxic metals may increase Parkinson’s risk.
  • Glutathione protects the body from damage. But heavy metal toxicity depletes glutathione.
  • IV glutathione*, under doctor’s supervision, may safely slow Parkinson’s progression and help reduce symptoms like brain fog, memory problems, difficulty walking and uncontrollable shaking. 

Shaking and Stumbling Through Life

Naturopathic Approach to Parkinson’s Symptoms

When 70-year-old JN** first came to see Dr. Crispo her right hand was shaking, and she had trouble walking. Twelve years earlier, when she had started stumbling, she had received a Parkinson’s diagnosis.   

Shortly after her diagnosis, her neurologist prescribed the medication carbidopa-levodopa. Despite taking it for nearly 12 years, her symptoms had slowly gotten worse. In the last 6 months, things had taken a sharp downturn. JN could no longer walk without a cane and the tremor in her right hand had intensified. Her vision had become blurry, and she noticed that she couldn’t remember things or answer questions as quickly as she used to. 

Her biggest challenge was stairs. Her 12-stair flight at home was getting harder and harder to climb. In fact, she couldn’t make it up and down the stairs more than once or twice a day. 

JN’s history revealed a 25-year career working as a phone line installer, two hip replacements and surgery on her right shoulder. Dr. Cirspo’s physical exam showed that JN walked with short steps. Her right leg was slower and stiffer than her left leg. Her posture and neurological exam showed nothing unusual. 

Dr.Crispo knew that JN had a neurological condition. But as there is no definitive test for Parkinson’s, Dr. Crispo was open to the possibility that JN may have another neurological condition that looks like Parkinson’s.

Hello? Its Heavy Metal Toxicity Calling

Dr. Crispo took careful note of JN’s former career as a phone line installer. He suspected that the resulting long-term exposure to heavy metals may have led to the symptoms that JN was experiencing. Research has shown that glutathione can protect cells from damage and help the body get rid of excess heavy metals, slowing progression of Parkinson’s and reducing symptoms. Knowing that glutathione is better absorbed when given as an IV infusion instead of taking oral supplements, Dr. Crispo prescribed one IV glutathione treatment to start. Most people don’t experience any adverse effects when taking glutathione. But people who are sensitive to sulfites, which are present in glutathione, may experience headaches, nausea, trouble breathing, and rashes. For maximum safety, Dr. Crispo opted to use a fairly low dose for the first treatment. 

The first IV glutathione treatment took 5 minutes. The results were nothing short of astonishing. Before the 5 minutes was up, JN’s hand had stopped shaking. By the time the infusion was complete, JN could walk down the clinic hallway without a cane, and her gait was normal. 

Despite these immediate and significant results, Dr. Crispo didn’t stop there. One week later, JN was still cane-free (even when climbing stairs), and the hand tremor had not returned. Dr. Crispo did another IV glutathione infusion at a higher dose.

Naturopathic Approach to Parkinson’s Symptoms

One week later, and JN was still symptom-free. In fact, her husband noticed that her mind seemed sharper and that she was answering questions more quickly. The ultimate test was the couple’s regular Jeopardy!-watching sessions. Her husband was delighted to hear her calling out answers, just like she had done in previous years. 

One week after that, Dr. Crispo did another infusion at an even higher dose. JN remained symptom-free for the next two weeks until she hit a snag. While away on vacation (and 18 days after her last IV infusion treatment), JN started having problems climbing stairs. Dr. Crispo arranged for her to get an IV infusion treatment while on vacation. It worked – she was quickly back to climbing stairs, and all symptoms continued to improve. 

One month after the last IV infusion, and JN’s symptoms have not returned. 

Outcome for Naturopathic Approach to Parkinson’s Symptoms 

In Parkinson’s cases where exposure to toxic metals like lead is a factor, IV glutathione may have immediate, long-lasting, and significant impact, resolving Parkinson’s symptoms and slowing disease progression. 

After 3 treatments of IV glutathione, JN is still going strong. She can still walk and climb stairs without a cane. Her hand tremor has not returned. And to the delight of JN and her husband – the Jeopardy! answers are coming fast and furious.

What’s next for JN? Because the treatment was so successful (with no reported adverse effects), JN will likely continue to receive IV glutathione infusions. How often she gets them, may depend on when/if her symptoms return.

Editor’s Note

What does JN’s case tell us about Naturopathic Medicine and Parkinson’s? Here are some key takeaways:  

NDs Get to Root Cause by Treating the Patient, Not the Disease. Taking a detailed case history is where NDs shine, to see where the health issue fits into the patient’s life narrative. If Dr. Crispo hadn’t asked about her job history and factored that in, JN’s outcome may have been very different. Dr. Crispo’s focus on the impacts of JN’s long-term occupational toxic metal exposure resulted in a dramatic improvement in symptoms. 

NDs Know How to Get the Lead Out. As a phone line installer for over 25 years, JN was routinely exposed to solder, wiring, and other sources of heavy metals. Dr. Crispo did urine testing, which revealed that JN’s lead levels were 8 times higher than normal. Dr. Crispo’s knowledge of potential sources of lead toxicity, testing, health impacts, and how to get it out of the body, resulted in a successful resolution of all symptoms. 

NDs are Experienced IV Glutathione Providers. Dr. Crispo went ‘low and slow’, by starting JN off on a lower dose of IV glutathione, watching for potential sensitivity, and making gradual increases. As a result, the patient safely experienced all the benefits of IV glutathione infusions without any of the potential adverse effects.

Bruce Barlean

Bruce Barlean is an owner and founder of Barlean’s, a global dietary supplement manufacturer located in the Pacific Northwest in Ferndale, WA. Bruce has been actively involved in the Natural Products industry since 1989 and is passionate about making a difference in the world and positively impacting the lives of others.

Bruce believes that people can make a difference in the world through ordinary purchases. He is committed to improving the quality of life for every person on the planet by making the best products and by using the profits to support outreach programs. Bruce summarizes it simply, “We make good stuff to do good stuff”.

In the late 1980’s Bruce became passionate about how health could be dramatically improved with Flax Oil Supplementation. Bruce along with his entrepreneurial parents saw the potential to improve the lives of many people and in 1989 they began selling Flax Oil under the Barlean’s name. From 1989 – 2000 the business grew an average of 40% year over year. While most companies saw a decline in business in the 2001 recession, Barlean’s continued to grow and soon became America’s #1 selling flaxseed oil and continues to be to the present. The brand has since expanded to include additional oils, green food concentrates and other premium supplements. Bruce continues to drive innovation and over the years his products and company have won countless awards including: Eight consecutive Vity Awards for #1 EFA, Six consecutive Vity Awards for #1 Greens Food Supplement, Natural Choice Award for Best Specialty Supplement, Best Product of the Year, Best New Product, Gold Medal Taster’s Choice Award, Gold Medal American Masters of Taste Award, #1 Health Food Store Brand for Consumer Satisfaction by Consumer Lab, and Manufacturer of the Year.

In 2013 as the company was on the eve of celebrating the 25th year in business Bruce and his parents decided to take their desire to help people to a new level that they call Pathway to a Better Life – which is now seen in the Barlean’s logo. Bruce and his parents had always been generous in their giving and support of charities, but as part of the Pathway to a Better Life they decided to increased partnership with charitable organizations such as: Vitamin Angels, Compassion International, KidsTown International, Autism Hope Alliance, Engedi Refuge, Project 92, and others. And because so many people are unable to meet basic nutritional needs, Bruce created a comprehensive Omega-3 and multivitamin formula that he distributes free-of-charge to local food banks. In addition, Bruce decided the company would supply food banks with organic coconut oil to provide people with a health alternative to standard cooking oils.

Always generous with his time Bruce has served as a youth leader for his local church for several years and continues to mentor youth. He has been on several not for profit boards including; Whatcom County Pregnancy Center (2003-2006), Natural Products Association (dates?), and the Institute for Natural Medicine Leadership Council (presently).

The Barlean family have been avid supporters of Bastyr University since the 1990’s and in 2013 were given Bastyr’s most prestigious honor, the Mission Award, which recognizes their leadership over time in improving the health and well-being of the human community.

Bruce currently resides in Ferndale, WA with his wife Lisa and their two dogs: Heinz & Shadow. When he’s not helping others he can be found fishing (catch & release).
