This guide distills nutrition into a tactical framework that matches the physiological sequence of healing. Rather than promoting an endless list of supplements, it organizes evidence-based strategies into a 4-phase “4R Model”: Reduce Inflammation → Repair Tissue → Rebuild Structure → Restore Function. Each phase highlights the nutrients and supplements most relevant to the biology occurring during that stage.
High-impact supplements—protein, creatine monohydrate, omega-3 fatty acids, vitamin D, vitamin C, magnesium, zinc, and probiotics—have strong evidence for supporting muscle repair, immune function, inflammation control, and tissue regeneration. Tools like curcumin and tart cherry offer targeted anti-inflammatory effects. Supplements like collagen or gelatin may offer comfort benefits but currently lack mechanistic evidence showing improvements in connective-tissue protein synthesis. The guide clearly differentiates between strong evidence, moderate evidence, context-dependent options, and low-ROI supplements to prevent unnecessary complexity.
The Supplement ROI Meter scores supplements based on Effectiveness and Practicality, helping practitioners and patients prioritize what truly moves the needle. Protein intake (1.6–2.2 g/kg/day) and creatine (5 g/day) are foundational for maintaining lean mass during immobilization or disuse. Omega-3s support inflammation resolution and neuroprotection. Vitamin D deficiency increases injury risk and slows recovery; correction is essential. Probiotics support immune health and gut integrity—critical during travel or periods of high stress.
Injury-specific protocols guide supplementation for bone healing, post-surgical phases, tendon/ligament repair, muscle injury, concussion, and immune stress. Bone and post-surgery protocols highlight vitamin D + K2, calcium, magnesium, omega-3s, and occasionally HMB. Tendon protocols emphasize vitamin C pre-loading and omega-3s, but note the limitations of collagen research. Muscle protocols prioritize protein + creatine, with optional tart cherry for soreness. Concussion protocols emphasize DHA-dominant omega-3s, creatine, magnesium threonate, and B-complex vitamins for neuroprotection. Illness protocols focus on vitamin C, zinc, probiotics, and vitamin D.
This guide aligns nutrition with physiology, making supplementation phase-specific, evidence-aligned, and practical for athletes and patients.
KEY POINTS
- Protein + creatine = strongest combination for muscle and recovery.
- Vitamin D, Omega-3s, Vitamin C, Magnesium = foundational across all injuries.
- Collagen is supportive but not a primary healing driver (mechanistic studies are weak).
- 4R Model guides supplementation: Reduce → Repair → Rebuild → Restore.
- Concussion: DHA, creatine, magnesium threonate, D + K2, B-complex.
- Bone/Post-Surgery: D + K2, calcium, magnesium, omega-3s, protein.
- ROI Meter prioritizes high-impact, high-compliance supplements.
- Consistency beats complexity—focus on what can be done daily.
