Creatine supplementation for performance & recovery 💪

The ergogenic benefits of creatine.

The emerging and evolving evidence supporting creatine as an ergogenic aid: history and applications

Study Details

This new review examined how creatine supplementation impacts…

⚡️ High-intensity performance

🔁 Recovery & muscle damage

🏃 Endurance & intermittent sport performance

🧠 Cognitive function & resilience

…across athletic, endurance, team sport, and tactical populations 📚

Here are the key findings ⬇️

Key Findings

Energy production & ATP resynthesis 🔋

👉 Creatine increases phosphocreatine stores, allowing faster ATP regeneration during high-intensity efforts

Strength & power performance 🏋️

👉 Consistently improves strength, power output, and training capacity, especially in repeated high-intensity efforts

👉 Strength gains of ~8% greater than training alone have been reported in some studies

Repeated sprint & team sport performance ⚽️

👉 Enhances repeated sprint ability, agility, and fatigue resistance

👉 Particularly relevant for sports with intermittent high-intensity demands like football and rugby

Training adaptations & muscle mass 📈

👉 Supports greater training volume over time → leading to increases in lean mass and hypertrophy

👉 Long-term use linked with meaningful increases in muscle fibre size and total body mass

Recovery from muscle damage 🔁

👉 May accelerate strength recovery in the days after intense or eccentric exercise

👉 Can reduce markers of muscle damage, inflammation, and oxidative stress (though findings vary)

Endurance performance 🏃

👉 No consistent benefit for steady-state endurance performance

👉 BUT improves high-intensity surges, finishing sprints, and interval capacity within endurance events

👉 May support glycogen resynthesis when combined with carbohydrate intake

Thermoregulation & hydration 🌡️

👉 Increases total body water and intracellular fluid

👉 May help maintain plasma volume and improve heat tolerance in demanding environments

Cognitive function & brain resilience 🧠

👉 May support attention, memory, and decision-making

👉 Can attenuate cognitive fatigue during sleep deprivation or stress

👉 Potential neuroprotective role in high-impact or contact sports

Inflammation & immune support 🛡️

👉 May reduce pro-inflammatory cytokines and oxidative stress following intense exercise

👉 Potential role in supporting gut integrity under high training loads

Typical dosing 💊

👉 Loading: ~20 g/day for 5–7 days (optional)

👉 Maintenance: ~3–5 g/day

👉 Or ~3 g/day for ~4 weeks to fully saturate stores without loading

Body mass considerations ⚖️

👉 Small increases in body mass (~0.5–1 kg) are common

👉 Can be beneficial for strength/power athletes but may impact running economy in some endurance contexts
