When it comes to running, strength and endurance often take the spotlight. But for serious runners aiming to improve performance and build muscle, supplements can play a valuable supporting role. Whether you’re training for a marathon or working toward a personal best, pairing the right nutrition & meal prep with targeted supplements can boost recovery, support lean muscle growth, and enhance overall fitness.
Why Muscle Growth Matters for Runners
Runners tend to focus on lean builds and cardio capacity, but muscle mass is critical for maintaining proper form, powering up hills, and reducing injury risk. Stronger muscles also improve metabolic efficiency and increase sprint capability.
Top Supplements to Support Muscle Growth for Runners
Protein Powders (Whey or Plant-Based)
Fast-absorbing whey protein, or pea/brown rice-based blends for plant-based athletes, supports muscle repair and recovery after long runs or strength training. Aim for 20–30 grams within 30 minutes post-run.
Creatine Monohydrate
Often associated with bodybuilders, creatine is also great for runners incorporating strength training. It helps with power output, recovery, and lean muscle development—especially during interval or hill workouts.
Branched-Chain Amino Acids (BCAAs)
BCAAs (leucine, isoleucine, and valine) help reduce muscle breakdown during intense runs and promote repair. They’re especially helpful on double training days or during calorie restriction phases.
Beta-Alanine
Ideal for runners doing high-intensity intervals, beta-alanine buffers lactic acid, improving endurance and helping build muscle during explosive efforts.
Omega-3 Fatty Acids
These healthy fats reduce inflammation, support joint health, and may assist in muscle protein synthesis. Fish oil or algae-based supplements are both effective.
Vitamin D + Magnesium
Runners often overlook micronutrients, but both are essential for muscle function, energy metabolism, and bone health—particularly if you’re training outdoors early or indoors.
Nutrition & Meal Prep Tips for Runners
Plan Your Meals Around Training: Ensure you’re getting a balance of carbs for energy, protein for repair, and healthy fats for sustained performance.
Pre-Prep Snacks & Recovery Meals: Having a shake or protein-rich meal ready after your run reduces the temptation to skip recovery nutrition.
Hydrate Smart: Don’t just focus on water—electrolytes and hydration salts help muscle recovery and performance.
Supplements aren’t magic, but when combined with smart training, meal prep, and consistent recovery strategies, they can give runners a valuable edge. Every athlete is different—listen to your body, track progress, and make adjustments as needed.
