Nutrition Tips to Support Injury Healing

When recovering from a sports injury, rehabilitation and load management are essential—but nutrition also plays a significant role in how quickly and effectively your body heals. The right dietary approach can support tissue repair, reduce excessive inflammation, and help maintain muscle mass during periods of reduced activity.

While no single food will “fix” an injury, consistent nutritional habits can meaningfully influence recovery outcomes.

Why Nutrition Matters in Injury Recovery

When you’re injured, your body increases its demand for nutrients to:

• Repair damaged muscle, tendon or ligament tissue

• Reduce and regulate inflammation

• Support immune function

• Maintain energy levels during reduced training

• Prevent muscle loss during inactivity

Without adequate nutrition, healing may be slower and return to sport more difficult.

Prioritise Protein for Tissue Repair

Protein is one of the most important nutrients during recovery, as it provides the building blocks (amino acids) needed for tissue repair.

Good sources include:

• Lean meat and poultry

• Fish

• Eggs

• Dairy products such as yoghurt and milk

• Plant-based sources such as beans, lentils, tofu and tempeh

Aim to include protein in each meal to support ongoing repair throughout the day.

Don’t Under-Eat During Recovery

A common mistake is unintentionally eating less due to reduced activity levels. However, injury recovery often increases your body’s energy requirements.

If calorie intake is too low, the body may:

• Slow down tissue repair

• Break down muscle for energy

• Delay return to full function

Maintaining a balanced intake helps ensure your body has the resources it needs to heal properly.

Include Anti-Inflammatory Foods

Inflammation is a natural part of healing, but excessive or prolonged inflammation can slow recovery.

Foods that may support a healthy inflammatory response include:

• Oily fish such as salmon, mackerel and sardines (rich in omega-3 fatty acids)

• Fruit and vegetables, especially berries, leafy greens and citrus fruits

• Nuts and seeds

• Olive oil

A varied, plant-rich diet is generally beneficial during recovery.

Key Micronutrients for Healing

Certain vitamins and minerals are particularly important for tissue repair:

Vitamin C

Supports collagen formation, essential for tendons, ligaments and skin repair. Found in citrus fruits, peppers and berries.

Vitamin D

Important for bone health and muscle function. Sunlight exposure is a key source, with foods such as eggs and oily fish contributing.

Zinc

Supports tissue repair and immune function. Found in meat, shellfish, dairy and legumes.

Calcium

Essential for bone health, particularly relevant for stress fractures or bone-related injuries.

Hydration Supports Recovery

Water plays a key role in nearly all bodily processes, including healing.

Proper hydration helps:

• Transport nutrients to injured tissues

• Remove waste products

• Maintain joint and tissue function

Even mild dehydration can slow recovery and affect physical performance.

Collagen and Gelatine: Do They Help?

There is growing interest in collagen supplementation for tendon and ligament injuries. Some evidence suggests that collagen intake, particularly when combined with vitamin C, may support connective tissue repair.

However, results vary, and it should be seen as a supplement to—not a replacement for—a balanced diet and rehabilitation programme.

Alcohol and Recovery

Alcohol can negatively affect injury healing by:

• Reducing muscle protein synthesis

• Impairing sleep quality

• Increasing inflammation

• Slowing tissue repair processes

Limiting or avoiding alcohol during recovery may improve outcomes, especially in the early stages.

Supporting Muscle Maintenance

If you’re less active due to injury, maintaining muscle mass becomes important.

This can be supported by:

• Regular protein intake

• Light resistance exercises where appropriate

• Avoiding prolonged inactivity when possible

Preserving strength can make return to sport smoother and reduce re-injury risk.

Simple Recovery-Friendly Eating Habits

You don’t need a complicated diet to support healing. Consistency is key.

Helpful habits include:

• Eating regular balanced meals

• Including protein in every meal

• Choosing whole foods over ultra-processed options where possible

• Eating a variety of colourful fruits and vegetables

• Staying well hydrated throughout the day

When Nutrition Alone Isn’t Enough

While nutrition supports healing, it works alongside:

• Appropriate diagnosis and treatment

• Load management

• Rehabilitation exercises

• Adequate sleep and recovery

If these areas are not addressed, recovery may still be delayed even with good nutrition.
