Sports Nutrition: Performance, Recovery & Muscle

The evidence-based supplements that actually improve performance, speed recovery, and support muscle growth.

Sports nutrition is one of the most researched areas in supplement science — and also one of the most marketed. This guide cuts through the noise to focus on what the evidence actually supports: the compounds with consistent, meaningful results across multiple studies for performance, recovery, and body composition.

The evidence-backed essentials

Creatine Monohydrate
Most researched supplement

The single most evidence-backed sports supplement. Increases ATP production for explosive power, strength, and high-intensity performance. Also supports lean muscle gain, cognitive function, and recovery. Safe for long-term use. Dose: 3–5g daily. No loading required.

Protein (Whey or Plant-Based)
Muscle repair & growth

Protein is the building block of muscle repair and growth. Whey is the fastest-absorbing option and highest in leucine. Plant-based blends (pea + rice) are an effective alternative. Target 1.6–2.2g protein per kg bodyweight daily. Post-workout timing matters most.

Beta-Alanine
Endurance & buffering

Increases muscle carnosine levels, which buffers lactic acid during high-intensity efforts. Most effective for efforts lasting 1–4 minutes. Causes harmless tingling (paresthesia) at effective doses. Dose: 3.2–6.4g daily, split into smaller doses.

Caffeine
Performance & focus

One of the most consistent performance enhancers across endurance, strength, and power sports. Improves focus, reduces perceived exertion, and enhances fat oxidation. Best cycled to avoid tolerance. Dose: 3–6mg per kg bodyweight, 30–60 min pre-workout.

L-Citrulline
Pump & endurance

Boosts nitric oxide production, improving blood flow to working muscles. Shown to increase reps to failure, reduce muscle soreness, and improve aerobic endurance. Also effective for recovery between sessions. Dose: 6–8g, 60 min pre-workout.

Magnesium Malate
Energy & muscle recovery

Athletes deplete magnesium faster than sedentary individuals. Malate form specifically supports energy production through the Krebs cycle. Reduces muscle cramps, soreness, and fatigue. Best taken in the morning to support energy throughout the day.

Recovery supplements

Omega-3 Fish Oil
Inflammation & joint health

Reduces exercise-induced inflammation and muscle soreness (DOMS). Supports joint health for longevity in training. High dose (3–4g EPA/DHA) consistently reduces delayed onset muscle soreness and supports faster recovery between sessions.

Tart Cherry Extract
DOMS & sleep recovery

One of the best-researched recovery supplements. Shown to significantly reduce muscle soreness, strength loss after exercise, and inflammation. Also contains natural melatonin to improve sleep quality — when you do your best recovery. Dose: 480mg concentrate daily.

Collagen + Vitamin C
Tendons & connective tissue

Taking hydrolyzed collagen with vitamin C before exercise has been shown to increase collagen synthesis in tendons and ligaments — the connective tissues most prone to overuse injury. Important for runners, weightlifters, and anyone with joint issues.

Electrolytes
Hydration & performance

Sweat depletes sodium, potassium, and magnesium — all critical for muscle contraction and performance. Even mild dehydration (2%) meaningfully impairs performance. Quality electrolyte supplementation matters for sessions over 60 minutes or in hot conditions.

Supplement timing

Pre-workout
30–60 min before

Caffeine, L-Citrulline, Beta-Alanine, creatine (if not already loaded)

Post-workout
Within 30–60 min

Protein (30–40g), creatine (if preferred post-workout), electrolytes

Daily / anytime
Consistent daily use

Creatine, Omega-3, Magnesium, Vitamin D3, collagen with vitamin C

The no-nonsense starter stack

For most recreational athletes: Creatine Monohydrate (5g/day) + Protein (25–40g post-workout) + Omega-3 (2–3g EPA/DHA daily) + Magnesium Malate (300mg morning). These four deliver the best return on investment across performance, recovery, and long-term joint health. Everything else is an upgrade, not a foundation.
