Your Brain Needs Building Materials to Heal Your brain consumes 20% of your total caloric intake under normal conditions. After concussion, metabolic demand increases while appetite often decreases. This creates a nutritional deficit at the exact time your brain needs maximum raw materials for repair (Ashbaugh & McGrew, 2016). Nutrition doesn't replace medical treatment or rest. It provides the molecular building blocks your brain uses to rebuild damaged cell membranes, synthesize neurotransmitters, manage oxidative stress, and fuel the energy-intensive repair process. Optimal nutrition won't cure concussion. Deficient nutrition measurably slows recovery. Focus on four nutritional priorities: omega-3 fatty acids for membrane repair, protein for neurotransmitter synthesis, antioxidants for oxidative damage management, and stable glucose for consistent energy supply. Omega-3 Fatty Acids: Top Priority DHA (docosahexaenoic acid) constitutes 40% of brain cell membrane fatty acids. Concussion disrupts membrane integrity through mechanical shearing and subsequent lipid peroxidation. DHA supplementation provides the raw material for membrane reconstruction (Oliver et al., 2016). EPA (eicosapentaenoic acid) reduces neuroinflammation through anti-inflammatory mediator production. The inflammatory cascade following concussion perpetuates neural damage. EPA helps resolve this inflammation faster. Recommended intake: 2-3g combined EPA/DHA daily from fish oil supplements or fatty fish (salmon, sardines, mackerel). This dose exceeds typical dietary intake and requires supplementation for most people. Start within the first few days post-injury. Food sources: Wild salmon (2g omega-3 per 6oz serving), sardines (1.8g per can), mackerel (1.6g per 6oz), walnuts (2.5g per quarter cup), and ground flaxseed (1.6g per tablespoon, though plant sources provide ALA requiring conversion to DHA/EPA). Protein for Neurotransmitter Recovery Amino acids from dietary protein serve as precursors for neurotransmitter synthesis. Tryptophan converts to serotonin (mood regulation). Tyrosine converts to dopamine and norepinephrine (attention, motivation). Glutamine converts to GABA (calming) and glutamate (excitatory signaling). Post-concussion neurotransmitter disruption requires adequate precursor supply for recovery. Insufficient protein intake delays neurotransmitter normalization, prolonging mood disturbance, attention deficits, and sleep disruption. Recommended intake: 1.2-1.6g protein per kilogram bodyweight daily. For a 70kg (154lb) adult, this equals 84-112g protein daily. Distribute across 3-4 meals for optimal absorption and stable amino acid availability. Food sources: Eggs (6g per egg), chicken breast (31g per 4oz), Greek yogurt (15g per cup), salmon (25g per 4oz), lentils (18g per cup), and cottage cheese (14g per half cup). Antioxidants for Oxidative Damage Concussion triggers oxidative stress through free radical production during the metabolic crisis. These reactive oxygen species damage neural membranes, proteins, and DNA. Your brain's antioxidant defense systems need dietary reinforcement during recovery. Vitamin C (500-1000mg daily) neutralizes free radicals and supports collagen synthesis for blood vessel repair. Citrus fruits, bell peppers, strawberries, and broccoli provide dietary vitamin C. Vitamin E (200-400 IU daily) protects cell membrane fatty acids from oxidation. Almonds, sunflower seeds, spinach, and avocado provide dietary vitamin E. Flavonoids from berries (blueberries, strawberries, blackberries) cross the blood-brain barrier and provide direct neural antioxidant protection. 1-2 cups of mixed berries daily supplies meaningful flavonoid intake. Curcumin (from turmeric) demonstrates anti-inflammatory and antioxidant effects in brain tissue. 500-1000mg curcumin supplement with black pepper extract (piperine) for absorption. Cooking with turmeric provides smaller but still beneficial amounts. Combine nutritional support with physical recovery through simplmobility's comprehensive concussion recovery programs. Exercises That Complement Nutritional Recovery Light physical activity improves nutrient delivery to the brain through enhanced cerebral blood flow: JME 1 Cervical rotation promotes vertebral artery flow delivering nutrients to posterior brain regions. JME 14 Chin tuck reduces cervical compression that restricts nutrient-carrying blood flow. JME 6 Cervical flexion maintains the neck mobility supporting optimal brain blood supply. JME 5 Controlled rotation supports cervical vascular health for nutrient delivery. Upper Body Exercises Supporting Recovery JME 42 Shoulder mobility maintains physical function supporting overall metabolic health. JME 150 Thoracic rotation supports spinal health and respiratory function for brain oxygenation. JME 152 Thoracic extension opens the chest for improved breathing and oxygen delivery. JME 166 Shoulder elevation releases tension while maintaining upper body conditioning. Blood Sugar Stability Your brain runs on glucose. Post-concussion metabolic dysfunction makes your brain more sensitive to blood sugar fluctuations. Blood sugar spikes (from refined carbohydrates) produce temporary energy followed by crashes that worsen cognitive fog, irritability, and fatigue. Eat regular meals. Three meals plus 2 snacks daily prevents blood sugar drops. Skipping meals during recovery produces predictable symptom worsening 3-4 hours later. Combine macronutrients. Pair carbohydrates with protein and fat at every meal. This slows glucose absorption, preventing spikes and crashes. An apple with almond butter produces more stable energy than an apple alone. Limit refined sugar. Candy, soda, white bread, and processed snacks cause rapid glucose fluctuations. Replace with whole grains, fruits, vegetables, and nuts for steady energy supply. Foods to Avoid During Recovery Alcohol is neurotoxic, disrupts sleep, impairs judgment, increases fall risk, and interferes with every recovery mechanism. Avoid completely until symptom-free for at least 48 hours. Most clinicians recommend 2-4 weeks minimum abstinence. Excessive caffeine (beyond 200mg daily) disrupts sleep, increases anxiety, and causes rebound headaches. One cup of coffee is acceptable. Energy drinks combining high caffeine with sugar and stimulants should be avoided entirely. Highly processed foods provide empty calories without the micronutrients your brain needs. They promote inflammation through omega-6 fatty acid excess and refined sugar content. Prioritize whole foods during recovery. Practical Meal Ideas for Recovery Breakfast: Scrambled eggs with spinach and avocado on whole grain toast. Provides protein, omega-3s, antioxidants, and complex carbohydrates. Lunch: Grilled salmon over mixed greens with blueberries, walnuts, and olive oil dressing. Dense in omega-3s, flavonoids, vitamin E, and protein. Dinner: Chicken stir-fry with broccoli, bell peppers, and turmeric over brown rice. Provides protein, vitamin C, curcumin, and stable carbohydrates. Snacks: Greek yogurt with berries and ground flaxseed. Trail mix with walnuts and dark chocolate. Cottage cheese with sliced bell peppers.

Fish oil (2-3g EPA/DHA daily) has the strongest evidence for concussion recovery support. Vitamin D (if deficient), magnesium (400mg daily), and creatine (5g daily) show promising evidence. Discuss supplements with your provider, especially if you take other medications. Does creatine help concussion recovery? Emerging research suggests creatine supplementation (5g daily) supports brain energy metabolism during recovery. Creatine provides a phosphate buffer for ATP production, potentially compensating for the metabolic energy crisis. Evidence is promising but not yet conclusive for clinical recommendation. Should I eat more or less after concussion? Eat enough to meet increased metabolic demands. Many patients under-eat due to nausea, reduced appetite, and reduced activity. Your brain's repair processes require adequate calories. Aim for your normal caloric intake or slightly above (an extra 200-300 calories daily) during active recovery. How soon should I start nutritional changes after concussion? Immediately. Begin omega-3 supplementation within the first 48 hours if possible. Optimize protein intake, increase antioxidant-rich foods, and stabilize blood sugar from day one. Nutritional support is one of the few interventions that begins immediately with no risk.
