6 Ways to Support the Brain After a Concussion Injury
A Functional Nutrition Approach to Brain Healing
A concussion is much more than simply “hitting your head.” Even a mild traumatic brain injury (TBI) can temporarily change the way brain cells communicate, produce energy, manage inflammation, and repair themselves. It can also affect balance, digestion, sleep, mood, and cognitive function.
That’s why recovery is about more than waiting for a headache or dizziness to go away. A comprehensive approach examines the various systems affected by the injury and asks: How can we create the best possible environment for the brain to heal?
What Happens to the Brain After a Concussion?
Following a concussion, the brain experiences a cascade of changes. Excitatory brain signaling increases, mitochondria may become less efficient at producing energy, oxidative stress and inflammation rise, and the brain may temporarily have less energy available at the exact time it needs more energy for repair.
This is sometimes described as a brain energy crisis—and it helps explain why fatigue, brain fog, headaches, difficulty concentrating, and other symptoms can linger even after someone begins feeling better.
Don’t Overlook the Vestibular System
Another important piece of concussion recovery is the vestibular system, located within the inner ear. It constantly communicates with the brain about movement, balance, and where your body is in space.
This guide incorporates concepts from the work of Dr. Kendal Stewart of NBX Wellness, whose approach emphasizes evaluating the vestibular system rather than assuming every persistent concussion symptom originates solely in the brain.
Persistent dizziness, vertigo, balance problems, motion sensitivity, difficulty with eye or head movements, or feeling overwhelmed in visually busy places may be signs that vestibular evaluation and rehabilitation should be considered.
Start With the Foundation: Nutrition
Before considering supplements, start with food.
The recovering brain needs protein, healthy fats, vitamins, minerals, antioxidants, and adequate hydration to help repair tissue, restore cellular energy, rebuild neuronal membranes, and support normal brain signaling.
Focus on high-quality protein, fatty fish and other healthy fats, colorful vegetables and fruits, fiber-rich foods, and consistent hydration. Build meals around protein + healthy fat + fiber-rich carbohydrates to help maintain steady energy.
The gut deserves attention, too. Vegetables, fruits, beans, lentils, nuts, seeds, and fermented foods can help support a healthy microbiome, while limiting excess alcohol, refined sugar, and ultra-processed foods helps keep the nutritional focus on recovery.
Once that foundation is established, targeted nutritional support can be considered based on individual needs.
The 6 Pillars of TBI Recovery
1. Calm the Glutamate Storm
After a concussion, the brain can become overstimulated by glutamate, one of its primary chemical messengers. Excessive signaling can place additional stress on brain cells and interfere with energy production.
Magnesium L-threonate is one nutritional option of interest because magnesium helps regulate excitatory brain signaling while also supporting cellular energy and normal nervous-system function. Other calming nutrients such as L-Theanine and GABA may support relaxation, calm focus, sleep, and nervous-system balance.
For those who prefer a combination approach, formulas containing L-Theanine and GABA can provide multiple calming nutrients in one product.
2. Restore Cellular Energy
The brain requires extra energy to repair and recover after an injury, but concussion can temporarily make it harder for brain cells to produce that energy efficiently. Supporting the mitochondria—the energy-producing centers of our cells—is therefore an important part of recovery.
Nutrients that support mitochondrial function and antioxidant defenses may be useful here. Creatine is particularly interesting because it isn’t just for muscles—the brain also uses the creatine-phosphocreatine system as an energy reserve. Creatine helps brain cells rapidly regenerate ATP when energy demand is high and is also being studied for cognitive performance, memory, mental energy, and brain resilience.
3. Support a Healthy Inflammatory Response
Inflammation is a normal part of healing. The concern is that when inflammatory signaling remains elevated, it places additional stress on brain cells.
Nutrients such as PEA (palmitoylethanolamide) can support the body’s natural mechanisms for regulating inflammation and nerve comfort, while turmeric/curcumin provides both inflammatory and antioxidant support.
Peoples Rx Top Pick: Turiva® by Ortho Molecular Products uses a Complete Turmeric Matrix that includes curcuminoids along with other naturally occurring turmeric compounds, providing broader support for inflammatory balance, antioxidant protection, and gut health.
4. Repair the Gut-Brain Axis
The brain and gut are in constant communication. Following a concussion, changes in the nervous system and inflammatory response may also affect digestion, the microbiome, and intestinal-barrier health.
A comprehensive gut strategy may include supporting the intestinal lining, maintaining a healthy and diverse microbiome, and providing compounds such as butyrate, an important fuel source for the cells lining the colon. Together, these strategies can support digestion, immune balance, intestinal-barrier integrity, and healthy gut-brain communication.
5. Promote Neuroplasticity
Neuroplasticity is the brain’s remarkable ability to adapt and form new connections. Nutrition can help create a supportive environment, but sleep, learning, appropriate movement, vestibular rehabilitation, and cognitive rehabilitation are equally important.
Two nutritional supports of particular interest are Lion’s Mane mushroom and omega-3 fatty acids.
Lion’s Mane contains compounds studied for their relationship to nerve-growth pathways and may support memory, focus, cognitive function, and overall nerve health. Peoples Rx Top Pick: Host Defense Lion’s Mane.
Omega-3s—particularly EPA and DHA—are important building blocks for the brain. DHA is highly concentrated in brain-cell membranes, while EPA and DHA also support healthy inflammatory signaling and communication between neurons. Peoples Rx Top Pick: Orthomega 820 by Ortho Molecular Products.
6. Personalize Recovery & Build Long-Term Resilience
Recovery doesn’t necessarily end when symptoms disappear. Long-term brain health means continuing to prioritize nutrition, quality sleep, hydration, stress management, appropriate movement, and individualized support.
This is where nutrigenomic testing, such as NBX GenePro+, may provide additional insight. GenePro+ looks at genetic pathways related to areas such as methylation, inflammation, antioxidant protection, glutathione, and detoxification. This information can help practitioners personalize nutritional strategies rather than using the same protocol for everyone.
The goal isn’t necessarily to add more supplements. It’s to better understand what your body may need most.
What About Peptide Therapy?
Peptide therapy is an emerging area of interest in neurological health and recovery.
Semax is being studied for its potential influence on neuroplasticity, cognitive function, stress resilience, and neuroprotective pathways. Peptides are short chains of amino acids that perform many functions in the body. Some peptides are ingredients in FDA-approved medications for specific conditions, while others being discussed for neurological health and recovery remain investigational. Current research does not establish that investigational peptides safely or effectively treat concussion, traumatic brain injury, or related symptoms.
If you are experiencing symptoms following a brain injury, consult a licensed healthcare practitioner who can review your health history, discuss evidence-based options, and determine an appropriate care plan. Compounded medications are prepared for individual patients when clinically appropriate and are not FDA-approved.
When Symptoms Linger
Every concussion is different. When recovery takes longer than expected, additional evaluation may help identify what is still getting in the way.
Depending on symptoms, this might include vestibular rehabilitation, vision therapy, cognitive rehabilitation, functional neurology, neurofeedback, or other individualized approaches. Functional testing may also provide additional information about mitochondrial function, oxidative stress, nutrient status, the gut microbiome, neurotransmitter activity, or genetics.
Gentle movement can also be an important part of recovery once medically cleared. Rather than assuming complete inactivity is always best, activity can be gradually reintroduced based on symptoms and tolerance.
Don’t Forget Sleep
Sleep is when the brain gets some of its most important recovery work done. Quality sleep supports memory, energy restoration, nervous-system regulation, and the brain’s normal metabolic housekeeping processes.
Aim for a consistent sleep schedule and create a dark, cool, quiet sleeping environment. Significant or persistent sleep changes following a concussion should be discussed with your healthcare provider.
Build a More Resilient Brain
Perhaps the most important takeaway is that brain health shouldn’t begin with an injury.
The same strategies used during recovery—supporting mitochondrial health, maintaining omega-3 status, eating a nutrient-dense diet, supporting antioxidant defenses and gut health, exercising appropriately, and protecting sleep—can become part of a long-term strategy for neurological resilience.
The Bigger Picture
There isn’t one “brain supplement” that solves concussion recovery.
A comprehensive approach starts with nutrition, hydration, sleep, stress support, and appropriate movement. From there, targeted nutritional support can address cellular energy, inflammation, gut health, and neuroplasticity. Testing can help personalize the approach, while persistent vestibular, visual, cognitive, or neurological symptoms deserve appropriate professional evaluation and rehabilitation.
Brain recovery happens in layers—and supporting those layers can help create a healthier environment for healing today and greater neurological resilience for the future.
