Nutrition for Musculoskeletal Injury Recovery
General nutrition principles that support rehabilitation after muscle, tendon, ligament, and bone injuries.
Musculoskeletal injuries heal through a predictable sequence of inflammation, tissue formation, and remodelling. Nutrition supplies the building blocks for that process and the energy your rehabilitation program requires, but it does not determine how quickly an injury heals.
The guidance below is general and evidence-informed. Any individual plan should account for your injury, medical history, medications, and food preferences.
Energy needs during rehabilitation
Healing tissue and rebuilding strength takes energy. After an injury, some people eat less because of pain, low mood, or reduced activity, while others eat more. Neither is a failure. The goal is to eat enough, regularly, to support your rehabilitation sessions and the recovery work happening between them.
If you are noticeably losing weight or appetite, or if you are unsure whether you are eating enough, raise it with your treating clinician or a registered dietitian.
Protein for muscle and tissue repair
Protein supplies the amino acids used to repair muscle and connective tissue. Including a protein source at each meal, and often at snacks, is a practical habit that supports repair without any special products.
Everyday sources
- Eggs, Greek yogurt, cottage cheese, milk, and fortified soy beverages
- Chicken, turkey, fish, lean beef, and pork
- Lentils, beans, chickpeas, tofu, tempeh, and edamame
- Nuts, seeds, and nut butters
Vitamin C and collagen formation
Vitamin C is required for normal collagen production, and collagen is part of tendon, ligament, and skin tissue. This is a normal nutritional requirement rather than a reason to take large doses: more than the body needs does not build stronger tissue.
Vitamin C rich foods
- Citrus fruit, kiwi, strawberries, and bell peppers
- Broccoli, Brussels sprouts, and tomatoes
- Potatoes with the skin on
Calcium and vitamin D for bone health
Calcium and vitamin D support bone strength. This matters for fracture recovery and for anyone whose activity has dropped after an injury. Dietary intake, plus safe sun exposure for vitamin D, covers the needs of most healthy adults. Supplement decisions are best made with your clinician.
Sources
- Calcium: milk, yogurt, cheese, fortified plant beverages, canned salmon or sardines with bones, tofu set with calcium, and leafy greens
- Vitamin D: fatty fish, egg yolks, and fortified milk or plant beverages
Magnesium and normal muscle function
Magnesium is involved in normal muscle contraction and nerve signalling. A varied diet generally provides enough. Very large supplemental doses can cause digestive upset and are not necessary for most people.
- Leafy greens, nuts, seeds, and whole grains
- Beans, lentils, and soy products
- Dark chocolate in moderate amounts
Omega-3 fatty acids
Omega-3 fats are part of a balanced diet and support general health. They are not a treatment for a musculoskeletal injury and will not shorten healing time on their own.
Dietary sources
- Salmon, sardines, mackerel, trout, and herring
- Walnuts, ground flaxseed, chia seeds, and hemp hearts
- Canola and soybean oils
Hydration during rehabilitation
Fluid needs rise with activity, heat, and exercise-based rehabilitation. Even mild dehydration can reduce strength, concentration, and tolerance for exercise, and can contribute to headache and muscle cramping.
- Drink regularly through the day and around your rehabilitation sessions.
- Water is the default; milk and unsweetened beverages also contribute fluid.
- Increase intake in warm weather or during longer or sweatier sessions.
Considerations by injury type
Muscle strains and contusions: adequate protein and total energy support repair. Progressive loading prescribed by your clinician is what builds strength; nutrition supplies the raw materials.
Tendon and ligament injuries: these tissues have a slower blood supply and healing is measured in weeks to months. Vitamin C, protein, and overall diet quality support normal tissue formation, but no nutrient speeds the timeline.
Bone injuries, including fractures: calcium, vitamin D, protein, and adequate energy matter. Smoking and heavy alcohol use are strongly associated with poorer bone healing.
Post-surgical recovery: requirements are often higher than usual. Follow your surgeon's instructions and ask about dietitian support if appetite is poor.
Habits that support recovery
The pattern of eating matters as much as individual foods. These are the habits most consistently associated with feeling well during rehabilitation.
- Eat meals at roughly consistent times, including breakfast.
- Build each meal around a protein source, vegetables or fruit, and a whole grain or starch.
- Limit alcohol, which impairs sleep and can interfere with healing and medications.
- Keep caffeine moderate and consistent rather than using it to compensate for poor sleep.
- Prioritize sleep, which is when much of the body's repair activity occurs.
- Avoid restrictive or elimination diets unless a qualified professional has recommended one for a diagnosed reason.
