Buying Guide: Key Considerations For Runners

  • Protein density and timing: For most runners, a protein intake of 20–36g per post-run shake supports muscle repair. Consider whether you want a whey-only option or a blend with additional ingredients like creatine for strength or collagen for joints.
  • Amino acids and BCAAs: Look for products that include essential amino acids and BCAAs to aid muscle recovery, reduce soreness, and support training adaptations, especially after long or intense sessions.
  • Digestibility and stomach comfort: Runners may have sensitive stomachs. Hydrolysed collagen and whey isolates can offer easier digestion. Unflavoured options allow blending with foods and beverages without affecting macros.
  • Macros and calories: If weight management is part of your plan, opt for low sugar, low carb and low fat formulas. Balance protein intake with carbohydrate timing around runs for glycogen replenishment.
  • Endurance support: Magnesium is a key electrolyte for runners. Magnesium citrate can aid in energy production, cramp prevention and sleep quality—consider as part of a broader recovery strategy alongside protein.
  • Joint and tissue health: Marine collagen products and collagen sachets focus on joint health, tendons and ligaments. If you frequently experience joint stiffness or soreness after runs, including collagen options could be beneficial.
  • Convenience and taste: Flavour variety and form (powder vs sachets) influence adherence. For busy runners, ready-to-mix options and sachets provide quick supplementation post-run or on the move.
  • Quality and sourcing: Look for GMP certification, clear ingredient lists, and transparent sourcing. Marine-sourced collagen and magnesium from purified sources may appeal to runners seeking specific sustainability and purity standards.
