Nutrition for Concussion Recovery
How ordinary, balanced eating and steady hydration support the rest of your concussion rehabilitation.
Concussion symptoms usually improve over days to weeks with appropriate rest and graded return to activity. Nutrition is not a treatment for concussion, but eating regularly and staying hydrated supports energy, sleep, and the daily function that recovery depends on.
This guide describes general, evidence-informed nutrition principles. It does not recommend any specific diet, supplement, or product as a treatment for concussion.
Why nutrition matters during concussion recovery
After a concussion, the body and brain are recovering from a stress event. Good nutrition does not treat a concussion and no food or supplement has been shown to cure one, but eating regularly, staying hydrated, and getting enough of the basic nutrients supports the energy, tissue repair, and sleep that recovery depends on.
Many people find that symptoms such as headache, nausea, low appetite, and fatigue make it harder to eat well in the first days and weeks. The aim is not a special diet. It is simply to keep meals and fluids steady enough to support the rest of your rehabilitation plan.
Protein and balanced meals
Protein provides the building blocks for tissue repair and helps meals feel satisfying, which matters when appetite is unpredictable. Spreading protein across the day, rather than saving it for one large evening meal, is often easier to manage when symptoms fluctuate.
Practical sources of protein
- Eggs, Greek yogurt, cottage cheese, and milk
- Fish, poultry, and lean meat
- Beans, lentils, chickpeas, tofu, and edamame
- Nuts, seeds, and nut butters
- A simple guide is to include a protein source at each meal and at one or two snacks.
Omega-3 fatty acids and where to find them
Omega-3 fatty acids are part of a normal, balanced diet and support general cardiovascular and nervous system health. They are not a treatment for concussion, and research does not support using them to speed recovery from a head injury.
Dietary sources
- Oily fish such as salmon, sardines, mackerel, trout, and herring
- Walnuts, flaxseed, chia seeds, and hemp hearts
- Canola and soybean oils
- Fortified eggs and some fortified dairy products
Magnesium, vitamin B12, vitamin D, and other nutrients
These nutrients have normal roles in nerve and muscle function, energy metabolism, and bone health. A varied diet usually covers them. Supplements are worth discussing with your clinician rather than starting on your own, since more is not better and some interact with medications.
Common food sources
- Magnesium: leafy greens, nuts, seeds, whole grains, beans, and lentils
- Vitamin B12: fish, meat, poultry, eggs, milk, and fortified plant beverages or nutritional yeast
- Vitamin D: fatty fish, egg yolks, and fortified milk or plant beverages, plus safe sun exposure
- Iron and B vitamins: meat, legumes, and fortified whole grains, which support normal energy levels
Hydration and regular meal timing
Headache and fatigue are common after concussion and can be made worse by dehydration or long gaps without food. Steady fluid intake and eating something every few hours often helps people feel more stable through the day.
- Keep water within reach and sip regularly rather than waiting until you feel thirsty.
- Aim for three meals plus one or two snacks, especially while appetite is low.
- If larger meals feel unmanageable, smaller meals more often are fine.
- Keep easy, low-effort foods available for days when symptoms flare.
Fatigue, headaches, and cognitive recovery
There is no food that restores concentration. What nutrition can do is remove avoidable contributors: skipping meals, going long stretches without fluid, or relying heavily on caffeine to push through fatigue. These habits often worsen headache and make thinking feel harder.
If you notice that symptoms consistently follow missed meals, long screen sessions, or poor sleep, that pattern is useful information to bring to your treating clinician.
Foods and beverages to limit
Alcohol is best avoided while you are recovering from a concussion. It can worsen sleep quality, increase headache, and interact with medications, and it is not recommended until your clinician confirms it is appropriate.
Caffeine is individual. Some people tolerate it well; others find it triggers or worsens headache. Large amounts, or a sudden drop in intake, can also cause headache. Keep intake modest and consistent, and discuss it with your clinician if headaches are frequent.
Highly processed foods and sugary drinks are not off-limits in a rigid way, but they should not crowd out the meals that carry protein, vegetables, fruit, and whole grains.
Sleep, routine, and working with your rehabilitation team
Sleep is one of the most important parts of concussion recovery, and nutrition and sleep influence each other. Regular meal times, limiting alcohol and late caffeine, and avoiding heavy meals close to bedtime all support a more consistent sleep routine.
If appetite, nausea, or headache is making it difficult to eat, or if you have food allergies, dietary restrictions, or a condition such as diabetes, ask for a referral to a registered dietitian. Your nutrition plan should fit alongside your physiotherapy, occupational therapy, and psychological care rather than replacing any part of it.

Speak with your physician, dietitian, or treating clinician before changing your diet or starting any supplement, particularly if you take medication or have a medical condition.
