Increasing gamma-aminobutyric acid (GABA) and balancing glutamate, brain chemicals called neurotransmitters, may help alleviate symptoms offibromyalgia(FMS) andchronic fatigue syndrome(ME/CFS). Glutamate stimulates the brain, while GABA calms it down, and both can be out of balance in people with these conditions.

When glutamate is too high and GABA levels are too low, as is the case with fibromyalgia and ME/CFS, symptoms like hyperalgesia, anxiety, restlessness, brain fog, insomnia, mental exhaustion, and low energy can occur or worsen.

There are both natural and pharmaceutical ways to go about getting glutamate and GABA back in balance.This article reviews your options.

Diet & Supplements for GABA/Glutamate Function

Supplements for altering the function of GABA and glutamate in your brain have not been studied specifically for FMS and ME/CFS, but there is some general knowledge about them.

A synthetic form of GABA is available as a supplement. However, the current medical opinion is mixed on whether or not it crosses the blood-brain barrier (BBB) and if it can correct neurotransmitter imbalance.

Some precursors include:

Before you start new supplements or make significant dietary changes, talk to your healthcare provider and pharmacist about potential risks and drug interactions.

Drugs That Alter GABA

Several drugs currently on the market alter brain activity of GABA. Many have been tested and/or used as FMS treatments, but less so for ME/CFS.

Could Yoga Increase GABA?

Yogais generally believed to be calming. Research suggests that it might increase GABA in the brain.

One study shows that those suffering from depression, epilepsy, post-traumatic stress disorder (PTSD), and chronic pain—all medical conditions that involve low GABA activity—show symptom improvement in response to yoga-based interventions. However, more research is still needed.

How to Lower Glutamate

Research suggests that a low-glutamate diet can lower glutamate levels, which may help to alleviate fibromyalgia symptoms. The low-glutamate diet consists of healthy, whole foods that are low in glutamate and aspartate.

High glutamate foods to avoid include soy sauce, aged cheeses, seaweed, mushrooms, tomato sauce, and flavor-enhancing food additives such as MSG. Aspartame, hydrolyzed proteins, and gelatin contain aspartate and should also be avoided.

Nutrients that help to lower glutamate levels include vitamin C, magnesium, vitamin D, and omega-3 fatty acids. However, supplements that come in capsules typically contain gelatin, which should be avoided. Opt for real food sources or liquid supplements.

Neurotransmitter Dysregulation

You may want to talk with your healthcare provider about ways to try and impact your GABA/Ggutamate balance. Remember that evennatural treatmentscan have serious side effects.

Other neurotransmitters that are implicated in these conditions include:serotonin,norepinephrine, anddopamine.

Frequently Asked QuestionsAn excess of glutamate can overexcite nerve cells. Symptoms of high glutamate include muscle tension, pain amplification, anxiety, restlessness, and trouble concentrating and focusing.The precise cause of high glutamate is unclear. It can occur because the body releases too much of it or glutamate receptors do not function properly. It is associated with chronic fatigue syndrome, fibromyalgia, amyotrophic lateral sclerosis, multiple sclerosis, Alzheimer’s disease, Parkinson’s disease, Huntington’s disease, and stroke.You may want to stay away from or limit soy-based sauces, oyster and fish sauces, Parmesan and Cheddar cheese, mushrooms, meat, and seafood, all of which are high in glutamate.
