Buying Guide
- Protein type and absorption: Fast-absorbing whey isolate-based blends support quick recovery after runs, while blends with whey concentrate may be more cost-effective for daily supplementation.
- Purity and certifications: Look for Informed Choice or similar certifications to ensure product purity and absence of banned substances, which is particularly relevant for athletes undergoing testing.
- Flavor and mixability: Consider how easily the powder dissolves in water or milk and whether the flavour suits your taste preferences for daily use after training.
- Nutrition profile: Check sugar, fat, and carbohydrate content to align with your dietary goals. Some runners prefer lower sugar to support endurance training without excess calories.
- Size and value: Larger tubs can offer better value per gram, but ensure you will use it before expiry and that the serving size fits your training schedule.
- Intended use: Post-workout recovery versus general daily protein top-ups. Some products are positioned as recovery-focused, while others are versatile for meals between sessions.
- Allergen considerations: If you have dairy sensitivity or dietary restrictions, verify ingredients and certifications to avoid unwanted allergens.
- Brand reputation and ecosystem: Some brands offer complementary products (creatine, amino acids, energy drinks) that can support a broader training plan, especially for runners with varied workouts.
