Sports Nutrition Weight Gainers

Build a more effective mass-gain routine with our curated selection of sports nutrition weight gainers, chosen for lifters, hardgainers and busy athletes across the United Kingdom who need convenient calorie support. These high-calorie powders and ready-to-mix shakes help you increase daily energy intake alongside a structured resistance training plan, without relying on guesswork. Whether you’re returning to the gym, training for strength, or simply struggling to hit macros, a quality mass gainer can make bulking more manageable and consistent.

Most formulas combine carbohydrates and protein to support a calorie surplus and muscle recovery, often featuring additions such as creatine monohydrate, BCAAs, fibre, vitamins and minerals. You’ll find options designed for post-workout refuelling, between-meal top-ups, or adding calories to breakfast. Choose a blend that suits your digestion and goals, including whey protein-based mixes, higher-carb profiles for faster calorie loading, and balanced macro splits for steadier gains.

How to choose a mass gainer

Match your gainer to training volume, appetite and tolerance. If you’re new to calorie-dense shakes, start with a half serving and increase gradually. Many athletes use a weight gainer after resistance training or as a mid-afternoon shake to keep intake on track.

• Target macros: protein-to-carb ratio for your bulking phase
• Calorie density: easier surplus with less meal prep
• Ingredients: creatine, fibre and micronutrients for performance
• Mixability and taste: a routine you can stick with
