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

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.

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.
