Supplements I Use During High Training Load. Evidence-Based Rationale
This is not a recommended checklist and not a substitute for food, sleep, or training structure. It is an explanation of why I personally use certain supplements during periods of high endurance training load, grounded in current evidence and physiological plausibility. Supplements are used to: ✅ support recovery capacity ✅ reduce risk of deficiency ✅ assist training consistency complement, not replace, nutrition fundamentals 1. Protein Supplement (Plant-Based, Complete Profile) Rationale: Endurance athletes have elevated protein requirements due to high rates of muscle protein turnover and oxidative stress. Insufficient protein intake is common, particularly during heavy aerobic blocks or when appetite is suppressed post-exercise. Current evidence supports protein intakes of approximately 1.6–2.2 g·kg⁻¹·day⁻¹ to support recovery, lean mass maintenance, and adaptation (Morton et al., 2018). For plant-based athletes, amino acid composition and leucine content are critical considerations, as leucine is a key regulator of muscle protein synthesis (van Vliet et al., 2018). Application: Used to support total daily protein intake Particularly useful post-exercise or when whole-food intake is limited, completeness matters more than branding Evidence Summary: When total protein intake is sufficient and well distributed, plant-based proteins can effectively support training adaptation (Phillips & Fulgoni, 2018). 2. Creatine Monohydrate Rationale Creatine supplementation increases intramuscular phosphocreatine availability, supporting ATP resynthesis during repeated high-intensity efforts. While classically associated with resistance training, this mechanism is relevant to endurance athletes who perform: surges and hills sprint finishes strength and injury-prevention work There is also emerging evidence for cognitive and neuroprotective benefits, particularly under conditions of fatigue and sleep disruption (Avgerinos et al., 2018).
