How Nutrition Can Aid Concussion Recovery
Concussions, or mild traumatic brain injuries (TBIs), are a frequent concern in sports and recreational activities. Recovery from a concussion involves more than just rest—it’s about giving the brain the right tools to heal, and nutrition can play a key role in that process.
In this article, written by TeamNutrition’s dietitians and nutritionists, we’ll explore how the food you eat and the nutrients you get can help your brain recover and get you back to feeling your best. Understanding these strategies is especially beneficial for athletes and sports enthusiasts looking for ways to speed up recovery and regain their performance.
What Happens to Your Brain During a Concussion?
When you experience a concussion, your brain endures significant stress that affects its normal function. This type of injury disrupts brain cell communication and triggers a chain reaction of events. These include inflammation, increased oxidative stress, and imbalances in the brain’s energy supply.
The injury often leads to symptoms such as headaches, memory problems, dizziness, and fatigue, which reflect the brain’s need for time, rest, and the right nutrients to recover (1). Recognizing how vulnerable the brain is after a concussion underscores the importance of providing it with optimal support during the healing process.
Nutrients That Help Your Brain Heal
Some nutrients have been shown to support brain repair and reduce inflammation after a concussion. Below are key nutrients that could make a meaningful difference in recovery outcomes:
1. Omega-3 Fatty Acids (DHA and EPA)
Omega-3 fatty acids, particularly DHA and EPA, are widely recognized for their role in brain health. Found in fatty fish like salmon, these essential fats help to reduce inflammation, protect brain cells, and stabilize cell membranes. Animal studies have shown that omega-3s can reduce damage to neurons and improve cognitive outcomes following a brain injury (2). In human cases, high-dose omega-3 supplements have shown promise, helping to promote healing without significant side effects (3). However, consistent, smaller doses in the diet may also benefit athletes recovering from concussions.
What to eat: Incorporate salmon, mackerel, walnuts, chia seeds, and flaxseeds into your meals. Omega-3 supplements can also be a practical option, particularly for those who don’t consume fish regularly.
2. Protein and Branched-Chain Amino Acids (BCAAs)
Protein is a crucial nutrient for tissue repair, and its components, especially branched-chain amino acids (BCAAs), play an important role in brain recovery. BCAAs include leucine, isoleucine, and valine—amino acids that contribute to the production of neurotransmitters and help restore the balance between energy supply and demand in the brain. Research has shown that BCAA supplementation improves cognitive performance and promotes synaptic repair after brain injury (4). For athletes, ensuring an adequate protein intake can be particularly beneficial as it aids not only brain recovery but also muscle repair from physical exertion.
What to eat: Opt for high-protein foods like eggs, lean chicken, turkey, fish, Greek yogurt, and cottage cheese. Protein shakes or BCAA supplements can also be a convenient addition to your routine.
3. Vitamins C and E
Some research suggests that Vitamins C and E may help improve recovery in people with severe brain injuries (5). These vitamins were found to reduce the risk of death, shorten hospital stays, and improve overall recovery in some studies. However, this research focused on more serious brain injuries, and it’s not yet clear if these benefits apply to concussions, which are milder. Scientists think these vitamins might help by reducing stress in the brain and supporting healing, but more research is needed to know for sure.
What to eat: Include foods like oranges, strawberries, almonds, and spinach in your diet. Talk to your registered dietitian before taking supplements to make sure they’re right for you.
4. Magnesium and Zinc
Magnesium is a mineral that regulates nerve function and helps reduce brain stress after an injury. Concussions can cause a rapid decline in brain magnesium levels, which may impair recovery if not replenished (6).
Zinc, another important mineral, is naturally eliminated through urine, but this loss increases significantly after a concussion. Supplementation has been linked to improved cognitive recovery and protein production, but results should be interpreted cautiously due to potential biases in studies (7-8).
What to eat: Eat magnesium-rich foods like leafy greens, pumpkin seeds, tempeh, and whole grains. Zinc can be found in oysters, red meat, poultry, beans, and fortified cereals. Supplements may be beneficial but should be taken under the guidance of a healthcare provider.
5. Creatine
Creatine is a natural compound found in muscles and the brain, where it helps produce energy. Studies on animals have shown that creatine supplementation can reduce oxidative stress and improve energy balance in brain cells after a concussion (2,4). While most research has been done on animals, creatine is widely used by athletes for its potential benefits in both physical performance and recovery from injuries, including brain injuries.
What to eat: While red meat and fish are natural sources of creatine, creatine monohydrate supplements are an efficient way to increase intake, particularly during recovery.
6. Curcumin
Curcumin, a compound found in turmeric, has shown potential for helping with concussion recovery due to its anti-inflammatory properties (9). Animal studies have found that curcumin can reduce oxidative stress and support brain repair by improving markers of brain health and adaptability. However, these effects have mostly been observed in rats using very high doses of curcumin, and more human research is needed to confirm its benefits (2).
What to eat: Add turmeric to soups, smoothies, or teas. Curcumin supplements are another option, but ensure they include black pepper extract (piperine) for better absorption.
Simple Tips to Support Concussion Recovery Through Food
While specific nutrients can play an important role in concussion recovery, overall eating habits also matter. Adopting a balanced and supportive diet can help your brain heal more effectively. Here are some practical tips to guide your food choices during recovery:
- Eat enough calories: Your brain uses more energy while it’s healing, so ensure you’re eating enough to meet your increased metabolic demands.
- Focus on whole, nutrient-dense foods: Prioritize fruits, vegetables, lean proteins, and whole grains to provide your brain with the nutrients it needs to recover.
- Stay hydrated: Proper hydration is critical for maintaining cognitive function and overall recovery. Drink water consistently throughout the day.
- Limit processed foods and alcohol: Junk food and alcohol can increase inflammation, delaying the healing process. Choose healthier options whenever possible.
Let Nutrition Be Your Secret Weapon
Recovering from a concussion isn’t just about rest—it’s about giving your brain the nutrients it needs to heal faster and feel stronger. By incorporating brain-boosting foods into your daily meals, you can reduce inflammation, repair brain cells, and improve overall recovery.
If you’re unsure where to start or need help designing a nutrition plan, a registered dietitian can guide you through the process. With their expertise, you can create a personalized approach to recovery that supports both your short-term healing and long-term health.
