Supplements for muscle growth

Muscle building supplements offer a powerful way to support muscle growth, repair, and performance. To effectively build muscle you need to be in a positive protein balance, which is where muscle gain supplements come in. Your muscles are continuously going through a cycle of muscle protein breakdown and muscle protein synthesis or growth. When muscle protein synthesis exceeds muscle protein breakdown, muscle mass increases. Taking supplements for muscle growth makes this process easier and also allows your muscles to repair quickly between workouts. 

The best supplements for muscle gain

We’ve created our range of muscle growth supplements to target all the systems in the body necessary for gaining muscle, including:

  • Protein  - Our power-packed whey protein powders and plant based protein powders support muscle growth and repair after training

  • Creatine - Boost strength and power during high-intensity training with creatine tablets and powders including our superblend CreaMag supplement

  • BCAAs - BCAAs, or branched-chain amino acids, aid in reducing muscle fatigue and promoting recovery to push you through your workout

  • Casein - Delivering a sustained release of protein throughout the day, casein protein builds muscle even while you sleep

  • Mass gainers - Replenish the calories lost during training with mass gainers to ensure you’re in a calorie surplus for maximum muscle gain 


Discover the best supplements for muscle gain from industry-leading brands, including CNP, The Health Project and Efectiv Nutrition at Discount Supplements now.
