Fracture healing is about quality as much as speed: proper immobilization/surgery + adequate nutrition + appropriate rehabilitation work together. Nutrition has three key pillars: protein, sufficient energy, and the calcium–vitamin D axis. Protein supports collagen and tissue repair; inadequate protein can slow healing. Adequate calories matter—overly restrictive dieting can delay recovery. Calcium and vitamin D support mineralization; if vitamin D is low, calcium benefits are reduced. Additional helpers include vitamin C (collagen synthesis), zinc, and magnesium. A practical plan: include protein at each meal (eggs/fish/yogurt/legumes), a consistent calcium source (dairy/fortified foods/tofu), plenty of fruits and vegetables, and adequate hydration. Smoking and heavy alcohol impair healing. In special situations (osteoporosis, older age, vitamin D deficiency), use clinician-guided monitoring and supplementation/treatment as needed.
