Gold Standard Whey – Protein powder

Protein is the building blocks when it comes to growing new muscle. It helps to repair tissues after you’ve broken it down, so it can develop to be bigger and stronger than before.

Because it’s so important to helping you recover and heal, it can also shorten recovery times and improve muscle protein synthesis. That way you can head back to the gym without as much muscle soreness.

A high protein diet has also been shown to help promote lean, fat free muscle, which is ideal if you’re looking to drop fat.

Protein powder is often a more convenient and cost-effective way to add protein to your diet and to help you reach the recommended 1.4-2g per kg of bodyweight every day.

Optimum Nutrition offer an excellent protein supplement. They use only whey protein, which offers a 24g serving of those key amino acids, along with low carbohydrate levels and low calories. This is important as it should fit easily into your diet without impacting your food tracking.

  • Improve lean muscle – High protein diets help to boost fat loss and is essential to muscle building
  • Support a healthy diet – Protein increases satiety, or that feeling of fullness you get after every meal. This powder will help reduce the likelihood of snacking between meals.
  • Help with strength and recovery – Taking whey protein can help improve strength, and muscle recovery during, and after exercise.

There you have it, a complete clean protein source that can help you lose weight, build muscle and help anyone stick to a healthy diet.
