Can ‘Medical Food’ Treat Chronic Pain?

By Pat Anson, PNN Editor

Do you keep a supply of gamma-aminobutyric acid in your medicine cabinet? What about hydroxytryptophan? Or the ominous sounding devil’s claw root?

They’re not exactly household names to the average person, but to Fabio Lanzieri they are essential ingredients in a new “medical food” product called Proleeva, a dietary supplement he developed that contains a blend of a dozen natural herbs, enzymes and amino acids.

“I fervently believe that prescription medications are very beneficial to man, but I also believe that nature does offer us the ability to find solutions to natural diseases. Because of this, I was always interested and read a lot about vitamins, supplements and bioflavonoids,” says Lanzieri, who spent nearly four decades in the pharmaceutical industry. “I believe that supplementing prescription medications with natural substances is the best way of treating chronic pain or any disease state.”

Several years ago, Lanzieri’s wife Maria began experiencing joint pain as a side effect of taking a hormone suppressant to help her recover from breast cancer.     

“I did start feeling the pain in my joints, particularly my fingers. I was having a really hard time sometimes just opening a bottle or doing simple things,” Maria told PNN.

To help his wife, Lanzieri began experimenting with different blends of herbs and other natural substances. Some, like ginseng and curcumin, have been used for centuries as natural remedies for pain and inflammation. Others, like choline bitartrate and L-arginine, have only recently been recognized as essential nutrients that help restore amino acids and neurotransmitters to healthy levels.

You can buy all of these supplements individually, but Lanzieri combined them all into one proprietary formula and gave it to Maria. Her joint pain slowly began to improve.

“After about a month, month and a half, I started having relief of those symptoms.  I didn’t have the joint pain. I felt like I could do a lot of those tasks that I couldn’t do before,” Maria said. “At one point I stopped taking it and it then was all coming back. It was weird. I didn’t think it was the Proleeva. I didn’t associate it with that. But then I went back on it and suddenly I was not feeling it again.”

The Lanzieri’s began sharing Proleeva with family and friends, who also reported positive results.

Only recently have they begun selling Proleeva to the general public on their website and through Amazon, marketing it as “the ultimate comfort food” that “helps bring your nervous system back into balance.”

A Proleeva bottle contains 120 capsules – about a month’s supply – and costs $40.

“I’ve been taking Proleeva for the last seven years and I don’t have any inflammation. I take it because it balances the body with the right ingredients that it needs to fight to heal itself,” says Lanzieri. “Your body needs amino acids and they are not reproduced naturally in the body. And over time, the older we get, the less we have of those amino acids. And therefore, we have to supplement them.”

For now, there is only anecdotal evidence to support these health claims, although a small clinical trial of Proleeva is underway.  Unlike pharmaceuticals, dietary supplements are only loosely regulated by the Food and Drug Administration, allowing supplement makers to introduce new products and make health claims without substantial evidence that they work.

‘One Formulation Makes a Lot of Sense’

Dr. Forest Tennant is intrigued by Proleeva. An expert in treating intractable pain, Tennant recommends that pain patients take gamma-aminobutyric acid (GABA), herbs and other supplements as part of their medical treatment to restore damaged nerve tissue and relieve pain.

“Having a lot of different supplements in one formulation actually makes a lot of sense, because we’re not certain which ones are going to work,” says Tennant. “But I do think there is some urgency or necessity in people with pain taking a variety of these supplements. They can’t hurt themselves and they probably are going to benefit themselves.

“And this particular product is doing something else. It recognizes that it’s got stuff in there like GABA that stimulates the nerve receptors that provide pain relief.”  

Tennant says the supplement industry has become more innovative than the pharmaceutical industry – particularly in an age when opioids and some other medications are harder to get.

“I think the innovation is really great,” Tennant said. “I really think that anyone who has chronic pain, particularly constant pain, really needs to be on a number of supplements right now. We’ll figure out exactly which ones work the best later, but right now I think taking a combination of these things is worthwhile.”

People who try Proleeva or other supplements should not expect instant results. It may take up to a month to feel any benefits.

“The biggest problem is making them stay with this for 30 days. We’re a society of instant gratification. Prescription drugs do that. But unfortunately, natural substances take time,” says Lanzieri.

What Pain Patients Should Know About the GABA Neurotransmitter

By Forest Tennant, PNN Columnist

“GABA” is short for the neurotransmitter, gamma aminobutyric acid. GABA is the natural (endogenous) biochemical substance in the brain, spinal cord, and all nerves that control electrical conduction.

Without proper GABA function, we experience pain. New research also shows that low levels of GABA make it harder to keep negative emotions such as fear, worry, anxiety and depression in check. 

All Intractable Pain Syndrome (IPS) patients have nerve damage somewhere in their brain, spinal cord, or nerves. Consequently, IPS patients will either need extra GABA or a GABA surrogate to force damaged nerve tissue to correctly function and relieve pain. 

GABA Surrogates

Without realizing it, you may already be taking a GABA surrogate. And you may have found that your pain gets worse without one. Here are the most effective prescription surrogates:

  • Gabapentin (Neurontin)

  • Carisoprodol (Soma)

  • Diazepam (Valium)

  • Alprazolam (Xanax)

  • Lorazepam (Ativan)

There are also herbs and amino acids available without a prescription that can be used as GABA surrogates:

  • Valerian root

  • Ashwagandha

  • Taurine

  • Brahmi

  • Bacopa

Glutamine: GABA’s Precursor

The term “precursor” refers to nutrients or raw material that help make a neurotransmitter. Glutamine is the precursor of GABA. A dose of 2000 mg or more of glutamine a day when taken on an empty stomach with vitamin B6 (2mg or more), will increase your natural level of GABA and probably reduce your pain levels. 

Pure GABA is available as a tablet, capsule or in sublingual (under-the tongue) form in most health food stores or online. Unfortunately, when swallowed in tablet or capsule form, GABA may be digested just like food or fail to cross the blood-brain barrier, and be rendered ineffective.

But sublingual GABA is well absorbed by the body and should be given a thorough trial by every person with IPS. You can take 100 to 300mg sublingual GABA to treat pain flares, or 100 to 200mg of GABA simultaneously with an opioid medication or GABA surrogate for added pain relief.

Why Pain Is Not ‘All in Your Head’

By Gabriella Kelly-Davies, PNN Columnist

Anyone who lives with chronic pain knows it can affect their emotions. Every morning when I wake with a migraine, I feel a sense of doom. My heart races and I panic about how I will cope with everything that lies ahead of me that day — the meetings, deadlines and responsibilities, not to mention family and social commitments that often end up taking a back seat as I scramble to find ways of simplifying my day.

After decades of living with chronic migraine, I now know these emotions intensify my experience of pain. Having said this, I know it is not “all in my head” as some might claim, but part of a complex interaction between my emotions and the way my central nervous system incorrectly processes pain signals.

Exciting new Australian research using sophisticated brain imaging is shedding new light on what happens at an emotional level for people living with chronic pain.

Chemical “messengers” known as neurotransmitters facilitate communication between brain cells. Some neurotransmitters are inhibitory, helping to dial down our emotions, while others are excitatory and increase the intensity of emotions. A molecule known as γ-aminobutyric acid or GABA is the main inhibitory neurotransmitter.

Neuroscientist and psychologist Sylvia Gustin, PhD, discovered that GABA levels are lower in people with chronic pain and this affects their ability to regulate their emotions. The link between lower levels of GABA and chronic pain had been shown in animal studies, but Gustin’s research, recently published in the European Journal of Pain, is the first time it has been demonstrated in humans.

“A decrease in GABA means our brain cells can no longer communicate with each other properly,” explained Gustin, an associate professor at the University of Sydney’s School of Psychology. “When there’s a decrease in GABA, it makes it harder to keep emotions such as fear, worry, anxiety and depression in check.”

Gustin’s research shows there’s a physical change in the central nervous system that helps explain the roller coaster of emotions people living with pain often experience.

“If you live with chronic pain, it’s important to remember it’s not you -- there’s something physically happening to your brain. We don’t yet know why this happens, but we’re working on finding solutions on how to change it,” Gustin told me.

Her research confirms that chronic pain, which affects one in five people worldwide, is more than just an uncomfortable sensation. “It can affect our feelings, beliefs and the way we are,” she says. “Almost half the people living with chronic pain also experience major anxiety and depression disorders.”

GABA is not the only neurotransmitter that behaves differently in people living with chronic pain. In an earlier study, Gustin and her colleagues found levels of the main excitatory neurotransmitter in the central nervous system – glutamate -- are also lower in people with chronic pain. Lower glutamate levels are linked to increased feelings of fear, worry and negative thinking. They disrupt how brain cells talk to each other, affecting the ability to feel positive emotions such as happiness, motivation and confidence.

“My research results are reassuring for people living with pain because they show that physical changes in the brain are contributing to anxiety and depression and it’s not a person’s fault they struggle with these emotions,” Gustin said.

Her research team recently developed and tested an online recovery program that teaches people skills to help modify negative emotions such as fear, worry, anxiety and depression. The program helps to address the neurotransmitter disruption in chronic pain.

“Online programs offer hope to people living with disabilities or those in rural and remote communities who often struggle to access pain management services,” she said. “Online programs are also ideal during COVID-19 lockdowns.

“We know that chronic pain is always present, and we can’t get rid of it. But we can change the way we experience it by learning new skills. Like all skills, it takes practice to master it, but we hope it will offer another tool for people to change the way they experience pain.”

Gustin says preliminary results of this research, which will be published in a few months, are encouraging. Several organizations, including Australia’s National Health and Medical Research Council and Medical Research Future Fund, the International Association for the Study of Pain (IASP) and the U.S. Department of Defense, are helping to fund her work.

How Chronic Pain Disrupts Emotions

By Pat Anson, PNN Editor

Does waking up with pain everyday put you in a bad mood? Do you lose your temper easily or worry a lot?

It could be a sign that chronic pain has created a chemical imbalance in your brain that makes it harder for you to keep negative emotions in check, according to a new study by Australian researchers.

“Chronic pain is more than an awful sensation,” says senior author Sylvia Gustin, PhD, a neuroscientist and associate professor at the University of Sydney’s School of Psychology. “It can affect our feelings, beliefs and the way we are. 

“We have discovered, for the first time, that ongoing pain is associated with a decrease in GABA, an inhibitive neurotransmitter in the medial prefrontal cortex. In other words, there's an actual pathological change going on.”

Gustin and her colleagues at Neuroscience Research Australia (NeuRA) used advanced neurological imaging to scan the brains of 48 people. Half of them lived with a chronic pain condition, while the other half had no history of chronic pain and served as a control group.

Their findings, recently published in the European Journal of Pain, showed that participants with chronic pain had significantly lower levels of GABA than the control group – a pattern that was consistent regardless of the type of chronic pain. 

Neurotransmitters help communicate and balance messages between cells in the brain and central nervous system. While some amplify signals (excitatory neurotransmitters), others weaken them (inhibitive neurotransmitters). GABA, or γ-aminobutyric acid, is one of the latter. It acts in the brain as emotional regulator that helps dial down our emotions.

“A decrease in GABA means that the brain cells can no longer communicate to each other properly,” Gustin explained in a news release. “When there’s a decrease in this neurotransmitter, our actions, emotions and thoughts get amplified.”

While the link between chronic pain and decreased levels of GABA has previously been found in animals, this is the first time it’s been demonstrated in humans. Gustin hopes the findings will encourage people with chronic pain who may be experiencing mental health issues. 

“It's important to remember it’s not you – there’s actually something physically happening to your brain,” she says. “We don't know why it happens yet, but we are working on finding solutions on how to change it.”

GABA is not the only neurotransmitter that’s impacted by chronic pain. In a previous study, Gustin and her research team found that levels of glutamate, the main excitatory neurotransmitter, are also lower than average in people with chronic pain. Low glutamate levels are linked to increased feelings of fear, worry and negative thinking.

“Together, our studies show there's really a disruption in how the brain cells are talking to each other,” says Gustin. “As a result of this disruption, a person’s ability to feel positive emotions, such as happiness, motivation and confidence may be taken away – and they can’t easily be restored.” 

Medication can help relieve chronic pain, but there are currently no drugs that directly target GABA and glutamate levels in the brain. Gustin and her team are developing an online emotional recovery program as a non-pharmaceutical option for treating neurotransmitter disruption. 

“The online therapy program teaches people skills to help self-regulate their negative emotions,” says Gustin. “The brain can't dampen down these feelings on its own, but it is plastic – and we can learn to change it.”
